Some edits for NPOV, MAINSTREAM
Wikipedia is a mainstream encyclopedia. As such, we are here to fairly report on cold fusion.
Here is an edit I did to help this article conform to the above doctrine:
Rationale:
- "Summary of evidence for cold fusion" is not NPOV. People do not agree that this stuff listed here is actually "evidence" "for" "cold fusion". Everyone can agree that these are the assertions of cold fusion proponents. Let's keep it at that.
- We need to be clear that the only thing being discussed (right now) in this section are cold fusion devices that were built and reported on by proponents. The previous version did not do that. The current version does.
- "As of 2008, over 200..." We agreed a long time ago that attaching particular numbers to claims is irresponsible. Since Wikipedia has no way of verifying the number of "proper" claims, or even what makes a "proper" claim, we should not be reporting the number of claims. The source that numbers them is not universally considered reliable and is, in fact, promotional.
- The Hubler review is cited as evidence for "how much" excess heat. Of course, this is not a reliable source for this claim. The amount of excess heat has varied and reporting solely on positive results is an example of publication bias. We need to avoid this. It is good enough to simply state that cold fusion proponents believe that excess heat has been reported and leave it at that.
- The statement about nuclear science theory and cold fusion explanations was clarified to let it be known that no "theory" of "cold fusion" has ever been accepted by anyone but cold fusion proponents.
- The listing of people who believe in excess heat is excessive, promotional, and unnecessary. We can cite the people, but listing them in the article text is Project Steve-esque. Wikipedia is a neutral encyclopedia, not an indiscriminate collection of information. Unless the report of the particular cold fusion researcher can be shown to be prominent, Wikipedia policy says to marginalize it. To show prominence, we need to show that independent sources (that is, sources who are NOT cold fusion proponents) think the claims are notable. That criteria has not been fulfilled.
- Specific claims of the "order of magnitude" of the nuclear products were removed as being essentially unverfiable. We can state that researchers claim nuclear products. The details of their claims have not been scrutinized independent of cold fusion proponents and therefore cannot be included in Wikipedia.
- Claims made by pro-cold fusion proponents from the DOE report were not vetted independently. They were, in fact, intended to be partisan. Including them is tantamount to a complete subversion of WP:NPOV. Therefore those specific claims of "independent verification" of nuclear transmutations have been removed.
- The novel process conjecture is one held solely by cold fusion proponents. Therefore I have rewritten the sentence to conform to this point.
- Iwamura's specific claims are not independently verified. As such, I have kept in a simpler summary and removed points that are obviously contentious.
I expect that cold fusion proponents will be none to happy with these changes. However, if we are to take it seriously that Wikipedia needs to be WP:MAINSTREAM these edits, or at least edits along these lines will need to be put in place.
If you wish to argue with any point above, please do so below.
People who agree with this edit are encouraged to say so in the interest of proving consensus. If only cold fusion proponents respond, we cannot properly gauge the level of support for this treatment of the subject.
ScienceApologist (talk) 00:09, 24 November 2008 (UTC)
- Support I first read this article a couple of days ago and was shocked at how bad it is (I'm a physicist). Your edits are a step in the right direction. As noted in WP:MAINSTREAM, Wikipedia should be presenting a highly fringe phenomenon in terms of the language of the maintstream, and the article doesn't do that. There's a lot more to do, I'll be happy to highlight some more problems and do the edits. Phil153 (talk) 00:45, 24 November 2008 (UTC)
- Support On balance these edits and associated proposals seem reasonable. As a complete outsider to this debate up to now I really would like to see a more neutral tone to the article because I suspect we may have an "in universe" mentality reflected in some sections rather than a mainstream one. If and when any breakthroughs happen supported by WP:RS we can happily add them to the article. That would be a more fitting approach for a serious encyclopedia. To put it in football terms let the cheerleading begin after the touchdown has been achieved but not before that. We don't need a blow by blow account of the state of the art of cold fusion. Just a general overview of the topic. Dr.K. (talk) 05:07, 24 November 2008 (UTC)
- Support On the whole, I think the article is shaping up. I would like to see more improvements though. In particular:
- "In 2004, the DOE organized another panel to take a look at cold fusion developments since 1989 to determine if their policies towards cold fusion should be altered"
- is misleading. The DOE did not undertake a review of the field as a whole. Instead, they agreed to consider a new petition from a group seeking DOE funding for cold fusion (referred to as "proposers") in a peer review process. The material considered was only that of the proposers. Instead of:
- "Various people who have reported a supposed demonstration of cold fusion have used a variety of devices"
- I would prefer something like
- "Cold fusion claims have involved a variety of devices"
- The statement:
- "The cold fusion researchers who presented their review document to the 2004 DOE panel said that "the hypothesis that the excess heat effect arises only as a consequence of errors in calorimetry was considered, studied, tested, and ultimately rejected"
- goes too far into the arguments and should be struck. It is much more interpretive than describing the kinds of apparatus cold fusion researchers use and the kinds of observations they claim to have made. You cannot observe "no calorimetry error." Likewise I would strike:
- "The cold fusion researchers who presented their review document to the 2004 DOE panel on cold fusion proposed that there were insufficient chemical reaction products to account for the excess heat.[79] However, the amount of helium in the gas stream was about half of what would be expected for a heat source of the type D + D → 4He.
- The former sentence is interpretive, the second is misleading and inaccurate. Finally, I would like to see:
- " has lead some cold fusion proponents to conjecture that new processes may by converting nuclear energy directly to heat"
- replaced with something more specific an accordance with the archived discussion. I think it is worth reporting that the proponents proposed an entirely new way in which high energy particles can interact with macroscopic bodies rather than attach significance to the absence of high energy particles.Paul V. Keller (talk) 16:15, 30 November 2008 (UTC)
- Support per all above. Verbal chat 16:19, 30 November 2008 (UTC)
- Oppose, obviously. Wikipedia is not a mainstream encyclopedia, as discussed here. On the contrary, it is a NPOV encyclopedia based on reputable, scholarly sources. The statements under dispute come from reliable sources, and we should not evaluate them further. Hopefully, this will be resolved by the ArbComm case. Pcarbonn (talk) 16:41, 30 November 2008 (UTC)
- Verifiability to reliable sources is a necessary but not a sufficient condition for including something. Wikipedia articles are not collections of all verifiable information on a specific subject. Hut 8.5 18:25, 1 December 2008 (UTC)
- Comment and follow-up I support Dr. Keller's proposals. They are reasonable and they address my concerns as expressed in my comments above. I don't think that the article will benefit by presenting in minute detail arguments and technical information contained in the sources or by micro-analysing and then trying to interpret technical details presented in reports or technical papers, especially if we still pretend that our readers need not be nuclear physicists in order to comprehend the article. Even if they were nuclear physicists there is still no agreement between them as to the exact processes involved so it is even more useless to include these highly detailed claims here. It is clear that this article does not have to be the battlefield of the micro-details as they continually unfold in the field. The analysis ethic in this article clearly needs to be more macroscopic. Dr.K. (talk) 19:54, 30 November 2008 (UTC)

You "skeptics" are astounding. You live in your own cloud-cuckoo land, where academic standards do not apply and conventional scientific evidence is not admitted. You say "Wikipedia" has "no way of verifying" the claims. What methods have you tried? Have you been to a library? Have you tried reading the mainstream, peer-reviewed journal papers listed at LENR-CANR.org? Our copies of these papers came from the libraries at Georgia Tech and Los Alamos National Laboratory. That's the kind of place people usually go to verify a claim. Your "information," on the other hand, appears to come out of a sewer, or you just make it up. In normal, accepted science (something you apparently know nothing about) replicated, high sigma peer-reviewed results from over 200 mainstream laboratories would be considered irrefutable proof that a claim is confirmed. You "refute" this proof by pretending it does not exist, or putting quote signs around the word 'proper.' In the words of the Bush administration, you are not members of the reality-based community, and consequently you have filled this article and this discussion area with absurd speculation and nonsense. - Jed Rothwell, Librarian, LENR-CANR.org
Let me explain something to this audience that you may not realize about the perspective of the cold fusion researchers regarding this debate. You are probably as ignorant of the field as the editors of the Scientific American are. They told me they have not read a single paper on the subject because it is “not their job.” They are certain that the effect was never replicated. Such people of course can have no notion who published these papers, where the papers were published, what the claims are, what experiments have been done, what instruments were used, or anything else. It is clear from the comments published by the Scientific American editors that they know none of these details, and they have in fact made up absurd nonsense about cold fusion, or dredged up it from the Internet. You can compare their statements to the experimentally proven facts to confirm this. As you probably know, in academic science it is customary to first read experimental papers before discussing them or criticizing them. People who do not do this are generally considered crackpots. Many distinguished experimentalists and theorists have contributed to cold fusion, including Nobel laureates, the Director of the Max Planck Institute for Physical Chemistry in Berlin; Iyengar, the Director of BARC and later chairman of the Indian Atomic Energy Commission; Prof. Melvin Miles, Fellow of China Lake; three editors of major plasma fusion and physics journals; a retired member of the French Atomic Energy Commission, and so on, an so forth, not to mention Martin Fleischmann, FRS. (You will find papers from all of these authors in the LENR-CANR.org library, and of course at the Georgia Tech and Los Alamos libraries.) Most researchers are distinguished senior professors because younger professors cannot get funding, because the research is controversial. These people are highly capable and certain of themselves. Many of them literally wrote the book on modern electrochemistry, calorimetry and other relevant fields. They do not make stupid mistakes. They have repeated the experiment thousands of times. They seldom read the kind of comments you skeptics make here, but when they do they instantly dismiss you people as a bunch of ignorant crackpots who do not understand the laws of thermodynamics, who have no clue how a calorimeter works, and who criticize papers they have never read. Naturally, I agree with them. You people imagine you are qualified to write an article about cold fusion. I doubt that you would casually edit some similar article about some other scientific research that you know nothing about, but for some inexplicable reason you imagine that you are experts on this subject, and that you can casually contradict the likes of Iyengar, Miles or Fleischmann. You imagine that their work is "discredited." This is unbelievable chutzpah. It is egomania. This is why Wikipedia will never become a viable source of information about this research. - Jed Rothwell, Librarian, LENR-CANR.org —Preceding unsigned comment added by 68.217.42.138 (talk) 23:14, 25 November 2008 (UTC)
As a scientist, the first thing I am looking for is reproducible experiments. Next, I am looking for reproducibility with progressively increasing precision to the point where the data shows what some of the important variables are and some rough functional relationships. Then I am looking for the all important steps of forming a theory and making predictions from that theory, followed by testing of the predictions, and thus the theory, by experiments. Cold fusion is way behind the curve on this flow. Cold fusion is still stumbling on the reproducibility part. The review cited in the main article describes 50-200% excess heat in 1/3 of the experiments, which is pretty sorry in terms of reproducibility. The 2004 DOE report, which is based on a report prepared by cold fusion research proponents, left 50% of the reviewers concluding excess heat itself had not been convincingly shown, to say nothing of quantified. Figure out what the variables are and start controlling them to get near 100% reproducibility followed by decreasing experimental error (measurement uncertainty) and you'll be doing science and you will have little trouble convincing people you are doing science. If you think the Pd electrode is the wild card, build a system with eight Pd electrodes to statistically average the effect, etc. Various reports of X-rays, gamma rays, neutrons, protons, helium-4, helium-3, and/or "anomalous" isotopic distributions do not make cold fusion science or advance the theory. A report of one of these products that is reproducibly quantified would be more convincing than the collective report of all of them. Cold fusion has made poor progress from the point of view of theory and experiment. Schwinger tried to help make cold fusion a science by giving it a theoretical framework. Given the absence of helium-4 (D+D), he postulated p+D -> helium-3 and a gamma ray. Given that no gamma ray was observed, he went out on a limb and postulated comparatively macroscopic well-ordered portions of the Pd array could take up the gamma rays before they are emitted. I would expect this to lead to experimentally testable predictions, such as a prediction that a Pd array will adsorb gamma rays of a certain frequency, or that gamma ray will be emitted if you alter the Pd lattice structure. I see no such predictions and experiments. Instead, the main proponents are now claiming helium-4. Every science has to start somewhere, but "cold fusion" has already had a good helping of time, effort and funding. The hypothesis is that electrochemically-induced nuclear reactions explain an experimental result. It was a far-fetched hypothesis to begin with, because the working theories of nuclear physics lead to the conclusion that a very high energy is required to bring the nuclei together and all past observations show nothing in the electrochemical system that could impart the required energy. Prediction based on that far-fetched hypothesis, such as gamma rays, did not bear out. Instead or rejecting the hypothesis, enthusiasts added another far-fetched theory: macroscopic lattices take up all the gamma ray energy before it can be detected. What prediction will be made on that theory? Could any experimental result cause proponents to reject the nuclear reaction theory, or is cold fusion now a religion? Cold fusion proponents, who decry for their lack of objectivity those physicists who assert cold fusion is impossible, brazenly assert that a chemical source is impossible, that all other energy sources are impossible, and that various types of experimental error are impossible. Ahem. Meanwhile, even the demonstrations of unaccounted for heat prove hard to reproduce. I see a very unconvincing case for cold fusion. I see a very convincing case for pathological science.Paul V. Keller (talk) 16:47, 29 November 2008 (UTC)
I cited my source above. The 2004 DOE report (which only looked at material gather by cold fusion proponents) and the review article cited in the main article. I also explained that good reproducibility would include quantitative results, not just qualitative result. The articles I cite are only talking about qualitative results.Paul V. Keller (talk) 23:55, 29 November 2008 (UTC)
Its not a question of whether I disageee. The point is that you and other cold fusion advocates are applying a double standard, one to when considering evidence contrary to cold fusion theory and one when considering evidence contrary to other theories that would explain the same data. Just look at what's written above. As far as speculating on a previously unidentified energy source or storage mechanism, that seems a little premature when more than half the DOE reviewers were not convinced there was even an effect to explain.Paul V. Keller (talk) 23:55, 29 November 2008 (UTC)
You need to make a prima facie case before you can shift the burden of persuasion.Paul V. Keller (talk) 23:55, 29 November 2008 (UTC)
* The maximum effect that is observed is produced by a causative agent of barely detectable intensity, and the magnitude of the effect is substantially independent of the intensity of the cause. * The effect is of a magnitude that remains close to the limit of detectability, or many measurements are necessary because of the very low statistical significance of the results. * There are claims of great accuracy. * Fantastic theories contrary to experience are suggested. * Criticisms are met by ad hoc excuses. * The ratio of supporters to critics rises and then falls gradually to oblivion.
I gave the foundation for my statement, and I was careful to qualify it as a matter of opinion. What I meant was that I find much more support for the hypothesis "cold fusion is pathological science" than for the hypothesis "cold fusion has been found experimentally". By pathological science I mean a theory that will not go away no matter how much evidence accumulates that it is not a good theory. In this case, I pointed out that the theory would have predicted gamma rays. Gamma rays were not found. Instead of rejecting the cold fusion theory and looking for other explanations for the data, the researchers came up with another far feteched theory: the lattice theory of direct energy transfer. As far as the specific factors go: The causitive agent remains unclear: Energy can be stored in many forms and heat effects can have innumerable causes. Effects near the limit of detectibility: The only evidence of nuclear reactions presented to the DOE was Helium-4 production, which was detected at background levels or barely above. When above, air contamination would explain the result (according to the report). As far as gamma rays: I do not even know if you claim them now. You mentioned X-ray plates. The 2004 DOE applicants did not claim gamma rays, but advanced the lattice theory. Claims for great accuracy: Check how many times "irrefutable proof" is used above. Btw, there is no such thing in science. Fantastic theory: Fusion at room temperature. Criticisms are met by ad hoc excuses (not to mention hostility): See the foregoing discussion I'll ask you specifically: could any experimental result cause you to reject the nuclear reaction theory? If not, is you belief in cold fusion different from a religious belief? If it hass become a religious belief to some, if it has a life of its own, if the theory cannot die no matter how poorly it performs, then pathological is a good description.Paul V. Keller (talk) 23:55, 29 November 2008 (UTC)

Another try at the intro
I have made changes to the intro which are relatively bold. I tried to gather similar references together and eliminate redundant statements, and I also changed some details of the phrasing. If you feel these changes are not in the right direction, I ask that we discuss the intro here. Olorinish (talk) 03:41, 25 November 2008 (UTC)
- I have said this before on the talk page but I disagree with the statement "Cold fusion gained a reputation as pathological science after several researchers presented reports of failed replication attempts at conferences and in journals." It wasn't so much that they "failed" to get result but "didn't" get the same conclusion. In fact many of them observed the same results but could explain it without fusion. It wasn't just a negative results the follow ups explained a large number of theoretical and experimental flaws in the original work. One of these follow-up papers was in the room I had group meetings and I would thumb through it when things got slow. I made edits to reflect this and they have since been reverted.--OMCV (talk) 05:23, 25 November 2008 (UTC)

- Who are you talking about? Which researchers observed "the same" results, and how did they "explain" them? Where did they publish? Please be specific. I am not aware of anyone who has observed megajoules of heat per mole of reactant, no measurable chemical changes, and yet who claims these results can be explained by anything other than a nuclear process.
- Unless you can cite specific authors, papers and claims, your statement is unsubstantiated opinion, and should not be included in a serious review of cold fusion.
- It wasn't just a negative results the follow ups explained a large number of theoretical and experimental flaws in the original work.
- Apart from the neutron results in the first paper, what experimental flaws do you mean? Again, which authors, and which papers do you refer to? What theoretical flaws do you have in mind? As far as I know, cold fusion is entirely experimental, without a theoretical basis, so how can there be theoretical flaws? The only theory involved are the laws of thermodynamics which govern calorimetry, and the various theories that govern mass spectroscopy, x-ray detection and so on. Do you think the laws of thermodynamics are in error? (I am asking seriously: some skeptics do claim that thermodynamics and calorimeters fundamentally do not work, and they say this is all that cold fusion researchers have discovered.)

OMCV, I see what you are talking about. What would an improved version look like? Olorinish (talk) 16:30, 25 November 2008 (UTC)
- Thanks for addressing my comments despite their stilted grammar. My point was that follow-up researchers claims on the work of Pons and Fleischmann were not limited to its irreproducibility (and thus fraudulence). The usual claim was that their cell was badly designed and they didn't account for all known phenomenon (poorly informed rather than liars). Phenomenon insufficiently accounted for included things like voltage vs. faradaic efficiency. I don't bring this up to discuss the validity of the pros or cons of P&F's claims. I think the page should be clearly state what the con claims were regardless of whether they are "right".
- I would direct the reader to Nate Lewis' analysis of the situation. For a simple example I'm sure many are aware of "the cell that exploded"; P&F believed this was the result of nuclear reaction but Lewis suggests it was the chemical reaction between hydrogen and oxygen in a semi-closed vessel. Thankfully not all scientists jump to conclusion they found a nuclear reaction every time they blow something up.
- The paper I was thinking of was Lewis NS, et al Nature 340 (1989) 525-530. At the moment I don't have a copy to reference but this paper is conspicuously absent from this page since for many researchers it was the definitive end of the P&F work and their version of cold fusion. The nature paper represents a bunch of reliable researchers publishing in a major journal a debunking of wild claims form a number of individuals on the fringe (some of them widely assumed to be crazy: Bockris). I'm not saying that this is right but this was the way many scientist understood the situation. This is the history regardless of content debate.
- Olorinish, I would like to write something but I would not be able to sufficiently cite it at the moment. But anyone who is widely read in the cold fusion literature should be able to explain my point. Jed Rothwell I see you have translated a book on the subject, maybe you could correct the error with proper citation.--OMCV (talk) 03:41, 1 December 2008 (UTC)
2004 DOE panel views
There had been agreement to include this in the intro description of the 2004 DOE report:
- Of eighteen reviewers, twelve decided the occurrence of low energy nuclear reactions was not conclusively demonstrated by the evidence, five were somewhat convinced, and one believed that the occurrence was demonstrated.
But that simple factual statement which puts proportions to the sides of the controversy has been considered "too detailed" and "cherry picking parts of the report to make cold fusion look better". Why? Why is simply telling the numbers from polling the jury too detailed? Why is it cherry picking?
Why is this information about the proportion of experts holding different viewpoints not an essential component of representing the different points of view neutrally in a controversial science article such as this one? 69.228.200.155 (talk) 13:53, 27 November 2008 (UTC)
- To me it seems out of place in the intro. The intro is meant to give a broad overview, not specifics, and the information is available later in the article so it's not being left out. Phil153 (talk) 14:16, 27 November 2008 (UTC)
- The consensus is, I believe, to keep the specificity out of the intro. We are more detailed in the relevant section. ScienceApologist (talk) 01:42, 30 November 2008 (UTC)
Reliable sources?
If we narrow down the complete biography to only the top APS journals, then here is the breakdown:
Journal | res+ | res0 | res- |
---|---|---|---|
Physical Review Letters | 0 | 0 | 4 |
Physical Review A | 0 | 6 | 0 |
Physical Review B | 0 | 10 | 18 |
Physical Review C | 1 | 1 | 11 |
I believe "res0" indicates neutral results, while "res-" is certainly negative. Some of these are strictly theoretical, but a few are experimental upper bounds contradicting the claims of cold fusion proponents. So how does the article currently cover this distribution of positive versus negative results?
Proponents estimate that 3,000 cold fusion papers have been published, including over 1,000 journal papers and books, where the latter number includes both pro and con articles.
Right, still some way to go before this article is NPOV wrt reliable sources, but at least the lead seems decently accurate now. Good work! Vesal (talk) 13:51, 30 November 2008 (UTC)
- I looked for the "res+" article in Phys. Rev. C and I believe it is the one by Southon et al. It is obvious that it should be labeled as a "res0" or "res-" article, which should raise doubts about all of the labels on that page. Olorinish (talk) 14:31, 30 November 2008 (UTC)
- Why do you assume that Phys. Rev. is the only reliable source of information? What about J. Electroanal. Chem. or Jap. J. Appl. Physics? In the past there have been many scientific controversies in which some journal editors turned out to be wrong, and others right. There is no reason to think that the editors of Phys. Rev. are better able to judge this issue than the editors of these other journals.
- In any case, "reliability" is not a function of the publication, but rather the instruments, techniques and signal to noise ratio, and by the number of independent replications. Cold fusion results are highly reliable by these standards. No other standards apply in science. Even if the results were not published at all, they would still be highly reliable.

- As far as WP:RS goes, reliability is a function of the standards of the publication. Hut 8.5 16:22, 30 November 2008 (UTC)
- I repeat the question then: Why is Phys. Rev. more reliable than Jap. J. Appl. Physics? The latter is the most prestigious journal in Japan. It is the journal of the Japanese Physical Society, just as Phys. Rev. is the journal of the APS. Is there a suggestion here that Japan is a second-rate nation, and that only American journals and scientific societies are reliable? Or that electrochemistry is not as scientific as physics? Cold fusion results have been published in the leading journals of plasma physics. Are these less reliable than Phys. Rev.?
- The APS has a long history of outrageous prejudice against fusion. Schwinger resigned to protest their attitude. Their journal reflects this attitude. They are not a reliable source of information about this topic.

- Nobody here is saying that Phys. Rev. is the only source of reliable information, and you know that. What is important is that the Physical Review journals are the most important mainstream journals for physics results, at least in the US and arguably in the world. Journals like theirs which routinely report on physics topics and are widely read by physicists are definitely more likely to correctly evaluate physics articles. I find it very significant that Mosier-Boss et al. chose to publish four of their articles in Naturwissenschaften, which is essentially a biology journal, rather that in physics journals. That doesn't mean they should be ignored completely, and in fact two are listed in the current version of this article. But it does suggest that the reports were not quite solid enough to pass the review process for Physical Review.
- Regarding the Japanese Journal of Applied Physics, my recollection is that none of those articles show any direct nuclear reaction detection data, but I could be wrong.
- Regarding the publication of articles in plasma physics journals, what articles are you talking about?
- Regarding your statement that "Even if the results were not published at all, they would still be highly reliable," it is important to remember that publication is extremely important to the modern scientific process.
- Regarding your claim that Physical Review is "not reliable on this topic," what evidence supports this, beyond the Schwinger episode?
- On another topic, I notice that you still haven't listed your choice of the three most persuasive reports of nuclear reactions related to cold fusion, as I requested. Olorinish (talk) 17:03, 30 November 2008 (UTC)

- Journals like theirs which routinely report on physics topics and are widely read by physicists are definitely more likely to correctly evaluate physics articles.
- The editors at Phys. Rev. have told me and many others that they have not read any papers on cold fusion, and they will not read or review any in the future. All papers are returned to the authors unread. So they know nothing about this subject.
- I find it very significant that Mosier-Boss et al. chose to publish four of their articles in Naturwissenschaften, which is essentially a biology journal, rather that in physics journals.
- This is because Phys. Rev., Nature and some other well-known journals summarily reject all submissions about cold fusion, without review, as I said. They have told Mosier-Boss and many others that is their policy.
- Regarding the publication of articles in plasma physics journals, what articles are you talking about?
- Fusion Technology, Nucl. Fusion Plasma Phys., J. Phys. D: Appl. Phys., J. Fusion Energy. (this is a kind of a trade magazine of the plasma fusion researchers, published by their lobby organization in Maryland, so perhaps it is not peer-reviewed . . . Not sure.)
- Regarding your statement that "Even if the results were not published at all, they would still be highly reliable," it is important to remember that publication is extremely important to the modern scientific process.
- I was kidding. Unlike you, I really do believe in the peer-review process and the importance of publications. That is why I am convinced that cold fusion is real: because of all those hundreds of peer-reviewed papers I have read. I believe in peer-review, but the Phys. Rev. editors do not, as I said, since they do send out cold fusion papers for review.
- Regarding your claim that Physical Review is "not reliable on this topic," what evidence supports this, beyond the Schwinger episode?
- The letters sent by their editors to me and to researchers.
- On another topic, I notice that you still haven't listed your choice of the three most persuasive reports of nuclear reactions related to cold fusion, as I requested.
- I did respond, but someone deleted my messages. Sorry about that. There is no point to responding again because I will only be censored again. In general let me suggest you start with the review articles by Storms at LENR-CANR.org because they are well organized and conveniently hyperlinked to the papers they refer to. The book by Storms has much more detail, with hundreds of footnotes.
- The principal nuclear reaction, obviously, is deuterium to helium plus heat energy in the same ratio as plasma fusion. Why this occurs without neutrons I have no idea, but the fact that it does occur is clearly shown by the instruments, in both real time (on-line mass spec.) and off line mass spectroscopy.

- Jed, your description of Vesal's comments is deceptive. You misrepresented him by stating that he viewed Physical Review as being the only reliable source on these topics, while he are clearly stating that it is a top source. That is a big difference because your version implies that he is being unreasonable.
- Your comment that "Unlike you, I really do believe in the peer-review process and the importance of publications," is also deceptive. I am a strong believer in the peer review process and everything I have posted on wikipedia backs that up.
- Regarding your comment that Physical Review and other journals refuse to review papers on cold fusion, is there a way I could see documentation of this?
- Your response to my request about articles was not deleted. It can be viewed by clicking "show" in the relevant section. So I ask again, please list the three reports (preferably not review articles) that you believe are most persuasive of cold fusion nuclear reactions. I also ask again for persuasive articles from significant fusion journals. Please give the title and authors, since it is not easy to find things at LENR-CANR.org.

- This list shows only paper from Phys. Rev. Anyone familiar with cold fusion will know that the editors at Phys. Rev. have it in for cold fusion. Listing this journal only, and leaving out the others, is biased. It is preposterous. That's my opinion and I'm sticking with it.
- Your comment that "Unlike you, I really do believe in the peer-review process and the importance of publications," is also deceptive.
- You and the other so-called skeptics have repeatedly erased peer-reviewed information about cold fusion and substituted your own unfounded opinions. You pay lip service to peer-review, but you have no respect for the system or its results. If you did, you would believe cold fusion is real, because the overwhelming number of actual published scientific results prove that to be the case, and not one credible peer-reviewed paper has ever been published showing an error in a major cold fusion result. The score is roughly 1000 to 0 in favor of cold fusion. Read the skeptical papers at LENR-CANR.org and see for yourself!
- I am a strong believer in the peer review process and everything I have posted on wikipedia backs that up.
- Perhaps you believe this but you do not know yourself. And you certainly do not know the literature on cold fusion!
- Regarding your comment that Physical Review and other journals refuse to review papers on cold fusion, is there a way I could see documentation of this?
- Sure! Ask the editors or anyone else at the APS. They are not shy about expressing their opinions on this subject. Ask Robert Park, who sets the policy on cold fusion at the APS. Read his columns.
- Your response to my request about articles was not deleted. It can be viewed by clicking "show" in the relevant section. So I ask again, please list the three reports (preferably not review articles) . . .

- I also ask again for persuasive articles from significant fusion journals. Please give the title and authors, since it is not easy to find things at LENR-CANR.org.
- Start with the papers I listed and then do your own homework, please. You may not agree with me about what is "persuasive." For example, I find it very persuasive when a cell with ~20 ml of water and a few grams of palladium produces megajoules of energy with no input power and no chemical changes, and it produces helium. I think that is proof that a nuclear reaction is occurring. However, you may not find that persuasive, so perhaps you should look at some other aspect of cold fusion, such as tritium production or host-metal transmutations.

All the articles you cite in the table above are from 1989 or 1990. Since then, other papers have been published in reputable sources, or by the 2004 DOE. NPOV requires us to present significant views that have been published in reputable sources. The balance of views should be based on published secondary sources, such as the 2004 DOE or review books published in academic press, not on our original research among a limited set of journals.

- Thank you, I looked briefly at the paper by Mosier-Boss, but I'm not an expert in this field. I would have to agree that it is "somewhat convincing", although they provide no explanation at all why this all might happen. Theories are under development... Still, I do not mean to say that these papers are insignificant, but when assessing due weight you also have to take into account the fact that the APS journals have only published negative results. That they now dismiss positive experimental results without review is actually sad, but I read somewhere that they are softening their stance... Vesal (talk) 22:02, 30 November 2008 (UTC)
- I looked at the paper by Iwamura et al. I found it well written, but it stretches credulity even further than the original cold fusion work. In each case, four seperate deuterium nuclei are brought to combine with single Cs or Sr nuclei. Even without energy barriers that would be a tall order. Nuclei are very small compared to the space around them. There would have to be intermediates. Even molecular reactions with more than two reactants necessarily proceed through intermediates. And the intermediates must be stable enough to survive until the following steps have time to occur. As a follow up, locating the intermediate species would make sense, but there are other things to do as well. Repetition by independent groups. Study of the way conversion rate varies with parameters such as D2 flux. If a new phenomena has been identified, it should be easy to engage in a process of developing a more detailed picture. This paper was published in 2002. What advances has Iwamura's group made in the last seven years?
- Iwamura et al. did reference a EINR model that might partially explain his results, but I could not find a report of that mode (that I did not have to pay for). It would be good to know not only what the model is, but what is being done to test it. What I am looking for is a scientific process.Paul V. Keller (talk) 23:11, 30 November 2008 (UTC)
- The Mosier-Boss work shows cold fusion research reversing its claim there are no gamma rays. Previous efforts to detect gamma rays failed. One direction taken was to come up with a spectacular theory, the lattice theory, to account for their absence (See 2004 DOE report). Mosier-Boss go in another direction, they get rid of the old detector and start using one operating on a different principle, with a scanty track record for detecting gamma rays and differentiating them from other emissions. The pits Mosier-Boss observed had many causes: the difference with the deuterium-free control was a matter of degree and not kind. If this field were advancing as science, I am sure gamma rays would be demonstrated in more ways than one and that there would be some reconciliation with earlier work failing to show gamma rays. We would be learning more about the types of gamma rays and their density. As it is, going to a new detector when the old one did not show the predicted result is more evidence of pathological science. If we were to amend the article in view of these papers, we could as easily use them to illustrate the pathological science aspect as to show an apparant confirmation of the original theory.Paul V. Keller (talk) 01:32, 1 December 2008 (UTC)
- Paul V. Keller wrote:
- . . . we could as easily use them to illustrate the pathological science aspect as to show an apparant confirmation of the original theory.
- Cold fusion is purely experimental. It is not based on theory, or guided by theory, and at present no theory can explain it. The notion that there is an "original theory" to "go back to" is nonsense. Szpak and others are trying to determine the nature of the reaction using different techniques. They are not trying to prove or disprove any particular theory, but rather to find out what nature has to teach us.
- Keller is incorrect about gamma rays. They have been detected with other instruments, by Iwamura and others. He wrote: "We would be learning more about the types of gamma rays and their density." We would be indeed, if the field were properly funded. Most cold fusion researchers pay for experiments themselves, and they cannot afford more elaborate or expensive equipment, so they use things like CR39, which is cheap. The field is not funded because there is enormous academic opposition to it, which comes mainly from people like Keller who do not read the literature and thus know nothing about the research, and yet who feel free to fabricate claims about it such as the notion that gamma rays have not been detected by other means! And also to free associate and invent new definitions for "pathological science" such as: "returning to the original theory."
- Despite the opposition, a great deal of progress has been made, and the effect is now produced at SRI nearly every time at power levels and input to output ratios 10 to 40 times larger than they were a few years ago. If this field were not "advancing as science" that would not be the case.

Wikipedia's reliability standards require a survey of the peer-reviewed literature, not some subset thereof (e.g. "top APS journals") selected to show a particular result. That the skeptics are reduced to such attempts to cherry pick shows exactly how far the peer-reviewed literature is from the imaginary "mainstream" which only exists as part of the prejudices of people who have invested their emotions in taking the side opposed to the experimental results. A neutral presentation requires summarization in accordance with the totality of peer-reviewed publications on the matter; any attempt to pick a subset which skews the result will be seen as such. I recommend going through the Britz bibliography of peer-reviewed papers and counting only the res+ and res- publications which are not based in theory, but rather in actual empirical experiments. 69.228.231.250 (talk) 10:54, 1 December 2008 (UTC)
- It's not the place of Wikipedia to do such research. Wikipedia doesn't do literature surveys except to establish notability. When providing a position on a field of study, we're limited to summarizing information about the topic from the most reliable second hand sources, such as meta reviews published in leading journals, the positions of authoritative bodies, the results of investigations by reliable NPOV parties, and newspaper articles from good sources. All of these, with no exceptions that I know of, consider cold fusion to be fringe science and largely unworthy of serious investigation or funding. See, for example, the DOE report, this article in the Washington post, which quotes prominent members of the physics community, and so on. See also: Wikipedia:Fringe#Notability_versus_acceptance Phil153 (talk) 11:39, 1 December 2008 (UTC)
- You say : "All of these, with no exceptions that I know of, consider cold fusion to be fringe science and largely unworthy of serious investigation or funding." You must be mistaken. The 2004 DOE, Hubler 2007, Biberian 2007, Storms 2007, Marwan 2008, are respected meta-reviews that say the contrary and are superior to news articles such as NYT for scientific topics. You'll see their full reference in our article. Again, Wikipedia is a NPOV encyclopedia, not a WP:MAINSTREAM encyclopedia. Pcarbonn (talk) 12:39, 1 December 2008 (UTC)
- You're claiming 2004 DOE contradicts my statement? The majority of reviewers said that even excess heat had not been established, let alone "fusion" being the most likley explanation. They clearly did not think it worthy of serious investigation or serious funding.
- The 2004 DOE says : "The nearly unanimous opinion of the reviewers in the 2004 review was that funding agencies should entertain individual, well-designed proposals for experiments that address specific scientific issues relevant to the question of whether or not there is anomalous energy production in Pd/D systems, or whether or not D-D fusion reactions occur at energies on the order of a few electron volts (eV).". So, yes, the 2004 DOE contradicts your statement. Pcarbonn (talk) 16:54, 1 December 2008 (UTC)
- I'm aware of what 2004 DOE says. But they don't recommend budgeting money for research, as they regularly do in other areas; they don't recommend putting together a task force or partnership with universities to do serious research into cold fusion. Their recommendation is that well designed proposals to investigate the remaining unknowns should be entertained. This is neither serious investigation nor funding, merely an acknowledgement that the area still has enough unknowns that solid proposals for research should be entertained. Contrast this with the Japanese government's direct funding and promotion of cold fusion research in the 90s (which they later abandoned after some years), or the ongoing, active DOE promotion of research into various aspects of fission and waste products.

- Biberian 2007 offers nothing new. Read his list of references, the large majority come from The Xth International Conference on Cold Fusion. He is presenting a non critical summary of claims published in completely unreliable sources. This is not a meta review of reliable primary sources, but an opinion piece published in a very questionable journal. The Int. J. Nuclear Energy Science and Technology, first published in 2004, could not even charitably be called a reliable source, especially for claims rejected by the mainstream scientific establishment.
- I haven't read Hubbler or Storms yet but I think it's clear that DOE 2004 supports my statement above, while Biberian 2007 fails completely as a reliable source.Phil153 (talk) 13:33, 1 December 2008 (UTC)
- Indeed, DOE won't recommend a cold fusion research program until the scientific controversy is favorably resolved. This is an economic decision. If they thought that the controversy was already negatively resolved, they would not have written what they have. So, the scientific controversy is still unresolved, and we should present both sides of it. And please, read Hubler 2007, Storms2007, and Marwan 2008 (ISBN 978-0-8412-6966-8) to have a full view of the reputable sources. Pcarbonn (talk) 17:43, 1 December 2008 (UTC)
- Actually, the DOE review says that there is a scientific case to justify funding some research, and gives advice on resolving "some of the controversies in the field". It doesn't say that the field itself has an unresolved controversy. --Enric Naval (talk) 01:06, 2 December 2008 (UTC)
- Concerning the replication of iwamura's work, here is what an older version of our article said : "The experiment was replicated by researchers from Osaka University using Inductively Coupled Plasma Mass Spectrometry to analyze the nature of the surface (the Pd complex samples were provided by Iwamura). " The source is : Higashiyama, Taichi; Sakano, Mitsuru; Miyamaru, Hiroyuki; Takahashi, Akito (2003), "Replication of MHI Transmutation Experiment by D2 Gas Permeation Through Pd Complex", Tenth International Conference on Cold Fusion, Cambridge, MA: LENR-CANR.org
- The replication was not by an independent group. One of the author's is the same. On the bright side, there is part of a theoretical discussion, and some proposals cosnsitent with what would be science as I asserted below (drafted earlier). On the downside, it looks like pure BS. Touching on one of the more tractable points, they said they needed a vacuum to get deuterium into the reaction zone. The vacuum only takes deuterium away from the reaction zone. Frankly, I am now doubting not just their accuracy, but their honesty.Paul V. Keller (talk) 00:02, 2 December 2008 (UTC)
Science without theory is not science. Experiments without hypothesis are not following the scientific method. All experimentalists rely heavily on theory, including the ones whose findings you credit. You need theory to interpret XPS and mass spectronomy data. You need theory to understand your calorimetry data. In fact, the closer you look at any of the experiments described in your literature, the more you will see reliance on hundreds of assumptions about the way things work. Theories get replaced and new hypothesis put forward, but if you throw away everything that's ever been known or thought to be understood, you will have nothing left to interpret your results. Experimentalists could not hypothesize fusion without drawing on theoretical understanding that such phenomena exist and release energy. Come up with a hypothesis to explain Iwamara and you will know what experiment to do next: if you agree it is a multistep process, figure out what intermediates to look for and in what concentration ranges to look for them. If you think the process starts with four deuterium chemically bonded to a Cs atom, predict what happens to the rate if you mix in 50% hydrogen and try to confirm that experimentally. Without that kind of process, it is not science.Paul V. Keller (talk) 23:32, 1 December 2008 (UTC)
- Iwamura's paper is scientific enough to be published in Japanese Journal of Applied Physics. We are not evaluating content here, only the reliability of sources. Also, you may want to read Thomas_Samuel_Kuhn or Paul_Feyerabend about what Science is and is not. Pcarbonn (talk) 11:47, 2 December 2008 (UTC)
- I agree that the steps you suggest would be beneficial. However, you are assuming that such experiments could produce reliable results. And that requires the phenomena to be highly reproducable. That's why scientists have been so focused on improving reproducibility and control, instead of doing experiments like you suggest. Without these two things, the results of experiments like you suggest would be so swamped by noise (statistical uncertainty) that they would be effectively meaningless. You see, good science requires a high degree of control, and these people, like good scientists, are working towards that goal.
- I don't know why you went on that spiel about theory, because obviously - as you, yourself point out - they would not be making any progress without it. But I hope you are not putting the cart before the horse here. Theory comes after experiment. After many, many experiments, actually. It models the results of empirical evidence, not the other way around. And it is far from a perfect model, as models inevitably are. But that's why we have science.

Nobody is saying that the Japanese Journal of Applied Physics or the European Physical Journal are less reliable. The problem is that almost every positive paper is cited, but not a single one of the negative papers from the above APS journals.

- Vasal asks:
- The problem is that almost every positive paper is cited, but not a single one of the negative papers from the above APS journals.
- There are no negative papers in APS journals, or anywhere else. Only about a dozen negative papers have been published in history of cold fusion. You will find most of them at LENR-CANR.org.
- There were several early papers describing experiments that did not work. That's a null, not a negative. The authors did not discover any fault in the positive experiments, or any other reason to doubt them. The reasons these early experiments failed is new well understood and has been described in detail.
- Actually, the three most famous negative papers, at Cal Tech, Harwell and MIT were false negatives. (Actually positive.) They all got excess heat at the same rate as others did in 1989, but they did not realize it, or they erased it and published fake results.
- As it happens, we just today uploaded a review paper discussing some of early failures, and the reasons for them:
- The authors examined 174 papers, in detail. They did a lot of analysis not shown in the paper. (I assisted so I know about it.)
- Every lab that has succeeded in reproducing the results is mentioned, but not those that failed or came up with experimental counter-claims. Why?
- There are no experimental counter-claims. No one has ever done an experiment that calls into question cold fusion, or an experiment with a prosaic explanation that exhibits the same behavior (i.e., one that produces tritium or megajoules of heat per mole of reactant.)
- The failures were all for obvious reasons not worth discussing in detail unless you are an expert. Of course you can read about them at LENR-CANR.org to your heart's delight. I have compiled a list of null and false negative experiments; contact me via the front page.
- - Jed Rothwell, Librarian, LENR-CANR.org
- Ugh, So much OR. Experiments with no results (failed replications) don't count as negative, and negative papers were actually positive because either the authors didn't notice they were positive or they lied about the results. Peer-reviewed papers published on top journals on the field are countered with proof from a cold fusion conference paper. My eyes, they hurt. --Enric Naval (talk) 07:01, 3 December 2008 (UTC)
- Enric Naval wrote:
- Experiments with no results (failed replications) don't count as negative . . .
- Obviously not, since the reasons they failed are well understood. When U.S. Vanguard missiles exploded in 1957 and 1958, that did not call into doubt the existence of the Russian Sputnik satellite. Negative experiments from labs that never succeeded failed for the same reasons some experiments failed at SRI and other successful labs: critical levels of loading, current density, flux or some other control parameter were not achieved.
- . . . and negative papers were actually positive because either the authors didn't notice they were positive or they lied about the results.
- Would you count them as negative? If you have any doubt that the data is fake, I suggest you review this paper, pages 21 - 24:
- Or this one:
- Peer-reviewed papers published on top journals on the field are countered with proof from a cold fusion conference paper.
- There are no peer-reviewed papers from top journals that call cold fusion into question. Not one study and not one paper has ever demonstrated an error in a positive cold fusion paper. If anyone ever did find an error, it would not only disprove cold fusion, it would overthrow the laws of thermodynamics and a large part of chemistry and physics going back to 1860. That isn't going to happen.

- Ummm...yes, there are two, mine and Brian Clarke's. I demonstrated that the interpretation of an apparent excess heat signal by Storms as due to 'cold fusion' was premature because he didn't consider calibration constant shifts. Jumping to an extreme, radical conclusion when a more conventional and understandable conclusion is available is an error. Brian showed that 4 'Case-type' cells submitted to him by McKubre et al for confirming analysis of anomalous He were in fact poorly sealed and had leaked to air, which is where the He came from. That's a big error on Mckubre's part. it makes one wonder how many more of his (and other's) experiments had the same flaw. Fortunately, both of these are in the article as it stands today. I'm glad you agree that they 'disprove' cold fusion (which of course can not ever be done in fact, only probabalistically).Kirk shanahan (talk) 21:41, 4 December 2008 (UTC)

- You can see at a glance that the data is fake! Part of the graph is replaced with crudely fabricated, hand-drawn data. The rest is regularly-spaced computer generated data. See D. Albagli et al., J. Fusion Energy, 1990, 9, pp. 133-148. That's peer-reviewed and often cited by skeptics, and obviously fake.
- You can tell even more clearly because one of the researchers accidentally leaked the original data, which shows excess heat in the part that was replaced with hand-drawn dots. You can also read the official MIT hearing in which the researchers claimed they had no idea how the data was changed and they think it means nothing. It is all on the record in official sources.
- All of this is described in the two papers I referenced above. I suggest you read something about this before commenting on it.
- As for the "reliable sources" on null experiments, of course they should be "taken into account"! Everyone takes them into account. We know why the null experiments produced no heat; we can see that the false negatives are actually positive (just do the arithmetic right and you will see this); and anyone who looks at the fake data in the peer-reviewed paper will see that it is fake. You do not need to take my word for any of this -- the data speaks for itself.

The purpose of the Wikipedia "Cold fusion" article
I keep reading here about various experiments published hither and yon and arguments about them. No! The purpose of the talk page is not to debate the subject but to improve the article. "Peer review" is not a talisman preventing error, since working scientists agree that most published results are just wrong and weigh them accordingly. But cold fusion advocates and skeptics do agree on one thing: "Cold fusion" is viewed as bunk by mainstream science. The Wikipedia article should not leave its readers with any other impression. --72.74.17.230 (talk) 12:06, 2 December 2008 (UTC)
- I think some advocates would disagree with that statement. Regardless, the intro is muddled and unclear on this point, I'd propose changing it to something like this:
- Cold fusion, also known as low energy nuclear reactions (LENR) or condensed matter nuclear science, is a name given to supposed nuclear fusion reactions hypothesized to occur at normal temperatures and pressures. Most physicists reject cold fusion as both an effect and a viable source of energy. However, low level research continues with some notable proponents.
- Cold fusion gained prominence in 1989 when Martin Fleischmann and Stanley Pons reported anomalous heat production in an electrolytic cell during electrolysis of heavy water using palladium electrodes, which they proposed was due to nuclear fusion. Significant scientific and media attention followed. In the months after their report, a lack of reliable replication of the initial experiment and the lack of a viable theoretical basis caused the field to fall into disrepute. Today it is considered a kind of pathological science and most scientists remain skeptical of the field.
Phil153 (talk) 14:50, 2 December 2008 (UTC)
- Oppose, obviously. Sources say that "most scientists" are skeptical, not that they reject cold fusion. Also, this intro is full of WP:weasel words, and gives too much weight to the view of "most scientists" as opposed to the one from reliable secondary sources. Pcarbonn (talk) 16:36, 2 December 2008 (UTC)
- Reliable secondary sources catalog this rejection, and note that many journals will not even publish cold fusion research. I think reject is a very reasonable term to use. "Skeptical" isn't a strong enough word to describe how most scientists feel about cold fusion.
- Also, weight *should* be given to the opinion of most scientists and the mainstream. If 95% of scientists think cold fusion is nonsense, it is far more important to stress this point in the introduction than anything cold fusion advocates say or publish.
- Anyway, I don't propose the above text as the new intro, merely an example of how strongly the mainstream view (and its reasons for rejecting CF) should be presented in the intro, in order to have a balanced and accurate article for a layman. Phil153 (talk) 16:45, 2 December 2008 (UTC)
- You are wrong about rejection. The American Chemical Society has published a review book on cold fusion in 2008, distributed by Oxford University Press, cited above as Marwan 2008. They wouldn't if cold fusion was rejected, and there was no market for it; on the contrary, it is a proof that it is not rejected. World Scientific Publishing has published a book in 2007. This is a reliable secondary source. "Rejection" is not a "reasonable" term to use according to reliable secondary sources (and "most scientists" is not a reliable source for wikipedia). Pcarbonn (talk) 17:04, 2 December 2008 (UTC)
- And yet, the author of LENR-CANR.org, one of the most pro cold fusion sites around, states: the editors at Nature and Sci. Am. denounced cold fusion as fraud. Since then, the journals I listed (and most others) automatically reject any manuscript about cold fusion, usually with a polite form letter. Several researchers have shown me these form letters. If that isn't rejection by mainstream science, I don't know what would possibly satisfy you. In addition, the US patent office rejects cold fusion applications, just as it rejects perpetual motion machines. Here is a reliable source that explicitly states the rejection by mainstream scientists:
- Erratic results such as those, coupled with the theoretical unlikelihood of the whole idea, long ago drove most mainstream scientists to dismiss cold fusion; they say that any indication of heat or nuclear byproducts is the result of an error in the experiment. Research money has dried up. The U.S. Patent and Trademark Office has refused to grant a patent on any invention claiming cold fusion. According to Esther Kepplinger, the deputy commissioner of patents, this is for the same reason it wouldn't give one for a perpetual motion machine: It doesn't work.

- Given the above, would you accept "dismiss" instead of "reject"? "Skeptical" gives a poor description of most physicists' rejection of cold fusion.
- Anyway, the scientist interest you are claiming does not exist except at the fringes. Also, one book - a book of evidence presented at a Chemistry symposium, or even several books - does not refute the fact that most physicists and physics journals reject cold fusion as stated above. Phil153 (talk) 18:39, 2 December 2008 (UTC)
- Yes, I would accept "dismiss" instead of "reject" : "dismiss" means that they choose to ignore cold fusion; it does not mean that they say it is wrong on scientific ground. That also explains why some journals choose to not publish papers, while others have: it depends on editorial policy, not on the scientific status of the field. Also, you have changed from "most scientists" to "most physicists" : that may also be more accurate, as chemists seem more open to the idea of anomalous effects that cannot be explained by chemical theory, whatever the explanation. Pcarbonn (talk) 11:52, 3 December 2008 (UTC)
- I like coupled with the theoretical unlikelihood of the whole idea. The theoretical side is very important to understanding main stream science's view of cold fusion research. The erratic nature of the results would not be given the same interpretation if there were a plausible nuclear theory to explain appreciable cold fusion or if the interpretation of results proposed by cold fusion enthusiasts did not require a radical yet unspecified revision of our current understanding of nuclear reactions. http://www.sciam.com/article.cfm?id=what-is-the-current-scien. (A 1999 article apropos today).
- A study showing rain dances produce rain would not be, and should not be, interpreted without considering what we know about weather. Likewise, a study showing time dilation in an atomic clock moved around at high speeds would be of little significance absent that it tested and showed results consistent with relativity theory. In this case, I am concerned that the plausibility of cold fusion is greater the less one knows about the science that came before it.
- A fundamental disagreement we have here is that one group thinks finding certain things implausible is bias, whereas another group understands finding certain things implausible is progress. Understanding what does and does not make sense is an important goal of science education. I have in mind here an anecdote at a commencement address about the response of legendary chemical engineering professor Neal R. Amundson to an inquiry about rumors of a chemical that could dissolve a tornado. Here, I think we would do a disservice if we left readers with a more optimistic view of cold fusion research than an understanding of science would warrant. The degree of contradiction with current theory and the significance of that contradiction need to be conveyed with clarity to do justice to this subject.Paul V. Keller (talk) 14:42, 3 December 2008 (UTC)
- I think that's an important point. One of the main reasons that true believers and skeptics talk past each other is the theoretical expectations. I like to think about it in terms of Bayesian priors. A similar case that springs to mind is the Fifth force. That field was also plagued with a few years of mixed results, but it was taken seriously (although eventually abandoned) because it was possible to think about the problem within the constraints of known physics. Anyway, we do not need to come to a consensus on the a priori likelihood of cold fusion and how that should affect our interpretation of the experimental reports. But we should make it clear in the article that the lack of theoretical underpinnings is considered by the skeptics to be a serious problem, regardless of the number of sigmas reported. Very similar to homeopathy as well. --Art Carlson (talk) 15:24, 3 December 2008 (UTC)

- A second set of reports on an attempted replication of the Patterson Power Cell can be found on Scott Little's Web page (http://www.earthtech.org/experiments/index.html) under the 'CETI' subsection. There was a third attempt made as I recall, by a guy named Shaffer or Schafer or such at the time. It was reported in sci.physics.fusion, but is probably long gone by now. None of the three replications succeeded.Kirk shanahan (talk) 16:16, 4 December 2008 (UTC)
- BTW, I should note that the Little papers contain that subsection of work that comments on the use of SIMS to support nuclear heavy metal transmutation that I tried to include in the 'Criticisms' section of the CF Wiki article, and which Pcarbonn block deleted.
- I have to plead guilty about putting technical discussions on these pages, but that was brought about because Pcarbonn wanted to argue every detail I tried to add. Some discussion was necessary anyway because I assumed the article should be written for an 'average' user not familiar with the field, and some of the quoted comments needed some explaining for those readers.
- In agreement with the comments above, the article always was too biased towards the 'reality' of cold fusion, and I tried to make it less so, with the result that I was opposed at every step by Pcarbonn. The general state of affairs regarding cold fusion today, as observed by myself as a worker in the field of the materials claimed to show CF, is that the average scientist thinks the issue was setled c. 1994, with CF being declared 'bad science' (or pathological or pseudoscience, they don't tend to distinguish between these various terms). Almost universally (including me), these scientists when presented with current CF papers or statements say "What? I thought that was over." A very few are aware it is not, most of them are somewhat incensed that CF is NOT dead, and, at this point, only one (me) has actually studied the field and published conventional explanations (the other, W. B. Clarke, passed away). This situation has allowed the CF die-hards to experience a resurgence of their view in the popular press, since not enough informed scientists are available to stop them (which is not a nefarious plot, they just do lousy science and rarely make it through a good peer review) and they actively suppress mention of the outstanding criticisms of their work. Thus we have the recent book published via the ACS.Kirk shanahan (talk) 16:49, 4 December 2008 (UTC)

Article on Reproducibility
Reproducibility contains some comments on cold fusion. Here is the relevant section (added by our neighborhood editor PCarbonn :))
- At the end of May the US Energy Research Advisory Board found the evidence to be unconvincing, and cold fusion was dismissed as pseudoscience. Later on, successful replications by independent teams were reported in peer reviewed scientific journals, and, although the effect is not considered fully repeatable, the field eventually gained some scientific recognition.
My concerns are:
- Was it initially dismissed as pseudoscience?
- Has it "eventually gained some scientific recognition"?
(The 2004 DOE report, which did not differ substantially from 1989 report, is used as evidence of scientific recognition).
I'm concerned that perhaps this doesn't leave a balanced impression of cold fusion for the casual reader. Phil153 (talk) 00:29, 4 December 2008 (UTC)
- The 2004 DOE report does not constitute scientific recognition. The DOE simply agreed to be open minded and here a renewed application for funding. The state of acceptance, or lack thereof, has remained unchanged for at least ten years. http://www.sciam.com/article.cfm?id=what-is-the-current-scien. A little research will show that these claims of breakthroughs and improved reproducibility are perennial.Paul V. Keller (talk) 01:54, 4 December 2008 (UTC)
- Phil asked if CF was initially dismissed as pseudoscience. Initially, the scientific community went to great lengths to reproduce the effect, and most could not, while a few did. The attitudes of F and P (driven most likely by intellectual property concerns) alienated a lot of scientists. Subsequently there was the 1989 DOE review, and the later book by its chairman, Huizenga, calling CF a 'fiasco'. At that point most scientists believed the issue to be settled and went on their way. A die-hard band of people however continued on. You can tell this by comparing lists of authors from the various ICCFs, they tend to be all the same people, with no significant influx of new blood. The field has not gained any scientific recognition to speak of. The large majority of cscientists think it is dead, and are shocked to find out it isn't. There was the 2004 DOE review, but that occurred due to political pressure from CF supporters, not because DOE thought there was any merit to the claims. Paul Keller correctly notes that the CFers contiunously claim breakthroughs. The recent claims of heavy metal trransmutations and radiation detection by CR-39 plates are just the most recent mutations of these claims. Note that this demostrates Langmuir's pseudoscience characteristic of always coming up with more ad hoc explanations when faced with solid criticisms. I should note however, that my own work assumes there is a real effect at work in the production of apparent excess heat signals, and the CFers ARE observing unexpected elements on their cathodes, but the point is one does NOT need nuclear reactions to explain these observations.Kirk shanahan (talk) 17:11, 4 December 2008 (UTC)
- Dr. Shanahan, do your concerns about calorometry apply to reports of experiments which do not involve electrolosys? 69.228.195.158 (talk) 18:20, 4 December 2008 (UTC)
- Potentially. The Calibration Constant Shift (as I call it) is a universal problem. It is nothing but a very simple concept that says if you need to convert a measurement via a calibration equation, you get the wrong answer if you use the wrong equation or constants. This applies to any and all calibrated measurements, in any and all scientific experiments. All I did was reverse engineer the constants required to force Storms' data to produce 0 excess power. That's called 'sensitivity analysis'. Then I noted that the spread in the computed calibration constants was trivial (1-3%), entirely consistent with 'good' analytical chemistry techniques. In other words, the 'noise' of the experiment can explain the apparent excess heat. Any other technique, such as a non-F&P type experiment, should be similarly analyzed to see if the normal variation in the technique can explain the results. Kirk shanahan (talk) 21:11, 4 December 2008 (UTC)
- Is it fair to say that "reverse engineer the constants required to force Storms' data to produce 0 excess power" means starting with the assumption that there is no excess power, and designing a general theoretical argument in support of that assumption? 69.228.195.158 (talk) 23:29, 4 December 2008 (UTC)
- Yes, but it also includes evaluating that argument and reanalysis for credibility. Kirk shanahan (talk) 13:18, 8 December 2008 (UTC)
- How do you select among a set of arguments in support of a selected hypothesis for credibility? What measure of credibility do you use? 69.228.201.246 (talk) 07:36, 9 December 2008 (UTC)
- (edit conflict) I haven't heard any claims of "breakthroughs" but I've read a number of articles about improved reproducability. Didn't a famous scientist recently reproduce the phenomena in front of a live audience? [4] It seems, as Paul suggests above, that reproducability has been slowly improving over time, as new methods are tried. Though I dispute the notion that "The state of acceptance, or lack thereof, has remained unchanged for at least ten years." I would say, rather, that it hasn't changed a lot. It's still not mainstream and many universities in the U.S. will refuse to publish research quite irrespective of its relative scientific merit. However, as the field has matured, recognition has increased over the years, the recently reinvigorated interest in India [5] being a prime example. Kevin Baastalk 18:01, 4 December 2008 (UTC)
- Dr Shanahan's work validates an edit to the definition of cold fusion that I recently made in the main article. Cold fusion is a phenomena hypothesized to explain a group of experimental results, it is not the results themselves.Paul V. Keller (talk) 19:38, 4 December 2008 (UTC)
- Excellent progress has been made in reproducibility, control and the power of the reaction. See:
- (Scroll down to "Some examples of progress made since 1989.")
- I attended the demonstration by Arata, and I was not impressed. See:
- Shanahan's hypotheses, if true, would disprove most electrochemistry and calorimetry going back to Lavoisier's 1781 ice calorimeter (which is used in some cold fusion experiments), and J. P. Joules's calorimeter circa 1845 (which is used in many others). There is no chance Shanahan is correct. The fact that skeptics such Paul V. Keller are so quick to believe him, and add his theories to this article, shows that they are grasping at straws, and they will believe anything that comes along without a critical examination, even if it means they must throw away the whole basis of chemistry and physics. It is often said that cold fusion appears to violate some laws of plasma physics. Many experts disagree, but in any case, the arguments made against cold fusion violate far more textbook laws than this.

As an example, I have explained to him many times what I explain above in answer to "69.228.195.158", but he still insists on spouting the 'Shanahan"s thesis will kill calorimetry' mantra. All my work does is show that baseline noise isn't the only noise in these exeperiments. The CFers know this, that's why they moved from isoperibolic calorimetry to integrating types like mass flow or Seebeck. All I did was put algebraic teeth into the problem, instead of just gut feel. Yet you see what Jed writes. My advice - ignore him. Kirk shanahan (talk) 21:11, 4 December 2008 (UTC)
- For those who are unaware of who Kirk shanahan is, I advise you to read his papers, carefully. Then read Storms' rebuttal. Then think for yourself.
- Excellent advice. Just make sure you read the response to the rebuttal too, the one that Storms didn't bother to mention in his 2007 book. It rebuts every point made by Storms, in a point-by-point fashion. Kirk shanahan (talk) 13:16, 8 December 2008 (UTC)
- That's the difference between me and anti-cold fusion people. I want people to read original sources from both sides. Do you own homework. Take no one's word for anything. I have put years of effort into making both pro- and anti-cold papers available to the public at LENR-CANR.org. My opponents, on the other hand, want you to ignore me -- just as they want you to ignore the scientific literature, and the laws of physics and chemistry.
- The difference if telling. I want everyone to know as much as possible. I have made hundreds of papers available, and people have downloaded 1.1 million copies of them. They want to squelch the debate and keep everyone ignorant, and Beware! Beware! of actual data and peer-reviewed papers! Oh my, better not to look -- which is why Robert Park brags that he has never read a single paper, even though he wrote a book attacking cold fusion. (It is obvious from his book that he knows nothing about the subject.)
- And by the way, if you want to know who I am, I suggest you read some of my papers at LENR-CANR.org.

Intro edit
I am not sure why there is a disagreement. Cold fusion is nuclear fusion occurring at near-ordinary temperatures and pressures. What is there to argue? Whether cold fusion is hypothetical, experimentally demonstrable, or apocryphal, it is still "nuclear fusion occurring at near-ordinary temperatures and pressures." I thought we should all restrain ourselves from trying to put our POV into the first sentence. I don't think there needs to be a word about what the experimental results are, not any weasels like "postulated" or "hypothetical". There is no reason to tip toe around what the subject is.
Although I want to change some things in the next paragraph, the discussion of Fleischmann and Pons is a great place to introduce the controvery. Both sides of the controversy see those events as seminal. From the main stream side, it flows into the explanation of why cold fusion is thought to be highly improbable. From the LENR side, it flow into the explanation of how their amazing work is being ignored. We can get well into this article, without saying anything prejudicial to either side.Paul V. Keller (talk) 23:01, 4 December 2008 (UTC)
- Something that has not been proven is by definition hypothetical or a postulate. There is nothing weasel about calling a spade a spade. If it is conclusively demonstrated to be real fusion then we can eliminate the qualifiers. But there is some way to go before we can do that. Until then a qualifier is an absolute necessity IMO. I don't think even the CF proponents would disagree with that. Dr.K. (logos) 23:10, 4 December 2008 (UTC)

- We agree that this article needs qualifiers, but all of the cold fusion researchers I know (roughly 1000 professional scientists) feel they have conclusively demonstrated the effect. Read their papers and you will see they express no doubts. This is because they have observed dramatic and incontrovertible proof such as tritium at 60 times background, or a million times background, or 20 W of excess heat continuing thousands of time longer than any chemical source of heat from the same mass of reactants could. Their assertions are unequivocal. For example, H. Gerischer was the leading physical electrochemist in Europe and the Director of the Max Planck Institute for Physical Chemistry in Berlin. He wrote:
- "In spite of my earlier conclusion, - and that of the majority of scientists, - that the phenomena reported by Fleischmann and Pons in 1989 depended either on measurement errors or were of chemical origin, there is now undoubtedly overwhelming indications that nuclear processes take place in the metal alloys."
- I can give you 50 other quotes as unequivocal as that from the creme de la creme of U.S. and European electrochemistry and nuclear physics. You may think there are doubts and open questions, but the researchers will tell you that all of the questions, doubts and criticisms raised here were rebutted in detail in the peer-reviewed literature by 1992.

- Perceptions are always a problem. It may take time for CF research to be adopted by the wider scientific community. But science should not and cannot hold grudges or frozen ideas for long. If the reproducibility, yield and sustainability of the reactions improves there is no reason why CF research will not be officially adopted and funded in universities, especially in the presence of such sustained effort by the current CF researchers. The jump to the mainstream will not be a long one after that. Dr.K. (logos) 03:41, 5 December 2008 (UTC)
- Dr. K. wrote: "But science should not and cannot hold grudges or frozen ideas for long."
- Perhaps it should not, but as Max Planck said progress in science occurs "funeral by funeral." He explained: "A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it." Unfortunately, most cold fusion researchers are elderly scientists and they are dying off faster than the opposition. It is a generational role reversal: Most cold fusion researchers were people like Schwinger, from the WWII Los Alamos era. One of them was the guy who pushed the button to trigger the first atomic bomb. They saw scientific revolutions. They were open minded. Above all they believed in the absolute primacy of replicated experimental evidence over theory. Cold fusion opponents are young people who 'shall never see so much, nor live so long,' as Albany put it -- with the sort of "end of history" conservative conceit that only unimaginative young people might feel. They actually believe that you must have a theory before you can believe the data! By that standard no one would have believed in radium when Curie discovered it. No one would have believed there is helium and a nuclear reaction in the sun -- not before 1939! Actually, by today's rules Bethe would not have even bothered to try to explain the anomaly. They would dismiss it as experimental error. Frankly, I have little hope the field will survive.

- Thanks for the elegant historical background but I don't think you should be pessimistic. I just saw a posting about new research interest in India, tabletop demonstrations in Japan. If the experimental evidence is strong enough and the scalability of the process is demonstrated, research interest will increase further and it will eventually reach critical mass. I don't think that lack of interest will be one of the factors that will influence the evolution of this process. Dr.K. (logos) 14:49, 5 December 2008 (UTC)
- I am pleased to say that I agree completely with Paul V. Keller on this: Whether cold fusion is hypothetical, experimentally demonstrable, or apocryphal, it is still "nuclear fusion occurring at near-ordinary temperatures and pressures." Exactly right.
- I disagree mildly on this:
- From the LENR side, it flow into the explanation of how their amazing work is being ignored.
- From the LENR side I say why bother bringing that up? It is obvious from other sources and this is an article on the science, not the politics. You could mention that in another article about academic politics and the disputes over cold fusion, such as this one:
- Of course the article must make it clear that many people do not believe cold fusion is real and some consider it pathological science. This is important and it should be close to the beginning. I inserted it in the Citizendium article:
- But having said that, you should move on to the scientific claims. Including positive and negative claims. Whether you believe them or not, you should simply enumerate them, and give the reader lots of original source material so that he can decide for himself. That is how I write science articles, including ones about subjects that I think are mistaken, or bunk. I never express my own opinions, but only documented opinions given by experts. I have translated, edited and critiqued hundreds of cold fusion papers (and dozens of technical articles and product reviews before that) including many that I think have no merit. I have disagreed with papers by cold fusion researchers and by by skeptics. Those authors never heard a single personal opinion from me. An editor, translator or librarian must be impartial. The skeptics know that I would not think of refusing a paper from them for LENR-CANR.org, or changing one word of it without their permission.
- - Jed Rothwell, Librarian, LENR-CANR.org
- Jed, I think we basically agree, although we will have to work through further changes one by one. There is not so much two sets of facts, as two sets of interpretations.
- Dr. K, ESP is "extra sensory perception", not "hypothetical extra sensory perception". "Time travel" need not be defined as "hypothetical travel in time". "Hypothetical" and "postulated" are unnecessary words that introduce a view.
- We do not give credence to cold fusion theory by talking about it without using words like "hypothetical" or "postulated". To the contrary, I think the careful use of those words says more to the reader about us than about the subject. Our care will just give credence to Jed's claims that everyone who does not believe in cold fusion has prejudged the subject. An expression of prevailing views can wait until we have presented a few facts to explain them.
- I do not disagree that cold fusion is a "hypothetical" or "postulated" phenomena, but those are facts about cold fusion rather than a definition of it. The reader will be aware of those facts quickly enough.
- And apologies to LENR people for "amazing work". I did not intend to be sarcastic.Paul V. Keller (talk) 00:13, 5 December 2008 (UTC)
- Dr. Keller, in your example of ESP it is clear that no one calls it a "hypothetical extra sensory perception" but one can define it as the "hypothetical perception which takes place outside the normal sensory avenues etc." Similarly "Time travel" is instantly recognisable, through experience, that it is the "hypothetical travel which occurs through time". But cold fusion does not carry such cognitive value, for most people, which automatically assigns a true or false perception to the idea, as in the case of ESP or time travel. So if we don't use qualifiers the statement will be taken as an endorsement of cold fusion, which IMO is not helpful, especially to the uninitiated. I can see your point, but that is the point of an expert. The average reader does not have your defences. That's why I think we need the qualifiers. Dr.K. (logos) 00:27, 5 December 2008 (UTC)

- I think you underestimate "most people." I agree that an article about cold fusion must clearly state that many scientists think the effect is not real. But you need only say this once, at the beginning of the article. You need not clutter up the rest of it with qualifiers. That is distracting, and confusing. This goes for purely hypothetical and imaginary subjects as well, such as Flatland.
- (By the way, the article should not say that "the vast majority of scientists" disagree because that is not in evidence. There have been only a few opinion surveys of scientists and engineers, but based on this fragmentary evidence it appears that roughly 40% believe cold fusion is real in some ways, and 60% reject it.)

- Well Jed, it was about time. I guess there is no way one can avoid meeting you if one stays on this page long enough. How are you? I'm glad to finally talk to you. I may not agree with all yout points but I respect your tenacity and the strength of your convictions. Surprisingly I agree with you on most of your current points, minus the point that I underestimate most people. Even on that point I would concede that I don't know the absolute numbers. Anyway you are right that it is an overkill to put qualifiers and disclaimers on every single occurence of the term "Cold fusion". I never advocated that. In fact it was only on the first two introductory sentences that I suggested any type of qualification. I am not a fan of making the article a semantic goolag, where every word carries its own semantic guard. That would make the article more rigid than a frozen Siberian steppe. So I do agree with you on this point. And of course I don't like weasel terms like majority or even vast majority either. I prefer numerical values such as 2/3 or 1/3 etc and I made similar comments on the Cold fusion Arbcom workshop. So here we are agreeing on virtually everything. A final point. I saw you asked about the reason of signing manually rather than through a robot. I think it is considered simply good etiquette to do so and in any case we wouldn't like to overwork our hardworking robot friends. Anyway thanks for your points; it's been nice meeting you. Take care. Dr.K. (logos) 02:51, 5 December 2008 (UTC)
- Returning to the subject of the lead paragraphs, we can take lessons in phrasing from other articles on controversial topics in science. See for instance Psychokinesis or Big Bang, both of which are FA status.LeadSongDog (talk) 16:52, 5 December 2008 (UTC)
- Following those models, I came up with:
- The term cold fusion has come to describe widely publicized claims that nuclear fusion can be achieved at temperatures far too low to be consistent with commonly accepted theories of nuclear physics. The reality of cold fusion is not accepted by the scientific community at large.
- If we leave it at that and save the definition of LENR and condensed matter nuclear science until the end of the intro, I think we have both sides covered. On the LENR side, there are hints that data exists and that everyone does not accept the mainstream view. The mainstream view is plainly stated. That one more assertion I would expect LENR side to want should be satisfied by concluding the intro with the LENR and condensed matter nuclear science definitions and a clear statement of their perspective.
- I like putting the definition in terms of current theory. Strictly speaking theory allow some infinitesimal amount of fusion at low temperatures, and by bombardment too if I am not mistaken. That would literally be "cold fusion" under the temperature definition, but that has nothing to do with "cold fusion" as meant on this page. As the term began to be used, there was definitely a connotation of "too cold". "Near room temperatures and pressures" is pretty meaningless without the theoretical context.Paul V. Keller (talk) 00:14, 6 December 2008 (UTC)
- I should also add that the definition I am proposing also makes a need distinction with Muon-catalyzed fusion, which is a low temperature fusion that is not inconsistent with commonly accepted theories of nuclear physics.Paul V. Keller (talk) 00:24, 6 December 2008 (UTC)
- Suppose it's a start, but really, are you serious about "' the reality of cold fusion'"? Wouldn't theory be exponentially less POV than reality? Kaiwhakahaere (talk) 00:29, 6 December 2008 (UTC)

- Non sequitar. Would you prefer "reality" to "theory"? Or reality to hypothesis, premise, suppostion or something similar etc etc etc? Kaiwhakahaere (talk) 08:14, 6 December 2008 (UTC)
- Perhaps "cold fusion hypothesis" would be a more appropriate phrase than "cold fusion theory". Is this dispute because of the difference between the scientific definition of theory versus the layman's definition?--Noren (talk) 07:46, 6 December 2008 (UTC)

Arata and Zhang's demonstration in Bangalore
Based on Kevin's comment above, I propose that Arata and Zhang's demonstration in Bangalore, India is the most notable recent event and should therefore be the last part (e.g., the subject of the last sentence) of the introduction. 69.228.201.246 (talk) 16:39, 7 December 2008 (UTC)
- I support that. Please note that the demonstration took place in Osaka, Japan, not Bangalore, India. Here are some more sources : PhysicsWorld.com (+ follow-up), slashdot.com, New Energy Times (+ list of more links). Pcarbonn (talk) 17:18, 7 December 2008 (UTC)
- Here's "Japanese Scientists Demonstrate Cold Nuclear Fusion" by a materials science news site. 69.228.201.246 (talk) 17:38, 7 December 2008 (UTC)
- Sorry, but I don't see any reliable sources in that list from PCarbonn. BTW, I'd encourage anyone with doubts about cold fusion to should read the physicsworld follow-up PCarbonn posted above. Note the differential involved relative to the heat produced by chemical reaction, and the fact that fusion is postulated to explain this. Kind of says all that needs to be said about the field.

- Note that in other cold fusion experiments this same differential technique has demonstrated ~10,000 times more output from cells than any possible chemical reaction, without producing so much as a milligram of chemical ash. That does indeed say all that needs to be said about the field. It is first principal proof that this is a nuclear reaction. What do you say in response? Do you think that could be a chemical reaction? Which one? Or are you one of these people who imagines that hundreds of scientists are incapable of measuring levels of heat that any competent scientist could have measured in 1850?
- If you don't believe that heat alone, without chemical change, is proof of a nuclear reaction than I presume you do not believe Madam Curie's observations of radium are of any importance, or that they prove there is an anomaly worth investigating.

- The links are not even to science publications, just news reports. As far as excess heat, I am going to take a wild guess, and assume the reporters did not calculate these sources of energy and compare the time-integrated input to the time-integrated output. Also, the reporters would be in no position to determine that the internal state of the system was unchanged between the begininning of the experiment and the end. Nor would they be in a position to determine whether helium production was being accurately measured and unaccountable by contamination.
- As Jed noted, these experiments were not notable in terms of either reliablity or documentation. These are very similar to the old reports that are not commonly credited. It would be new if they showed quantitative control over the amount of excess heat or helium production. It would be new if they showed a particular functional relationship between rates and different hydrogen isotopes mixtures. A theory of the process that is not demonstrably flawed would also be new. Stagnation at the stage of just trying to show heat or helium without much in the way of a theory to build on is part of the picture of cold fusion research.Paul V. Keller (talk) 22:50, 7 December 2008 (UTC)

- The reporters did not calculate anything. Arata and Zhang and their Chinese co-workers calculated the sources of energy and so on, and they certainly know how to integrate energy, although I take issue with their estimates of inputs, as noted. Anyway they have now gotten so much out the issue is becoming moot. Even lousy calorimetry works at this stage.
- These are very similar to the old reports that are not commonly credited.
- No, they are quite different. If they were the same, no one would question them because Arata has been replicated and carefully, independently checked at SRI and elsewhere, with better equipment than he himself used. There is no question that his basic technique works, but whether the new zirconium material works as well as he claims is an open question.
- The old reports may not be "commonly credited" but neither Keller nor anyone else has ever pointed to an experimental error in them, so either the the results are right or calorimetry does not work. Whether people credit them or not is irrelevant.
- It would be new if they showed quantitative control over the amount of excess heat or helium production.
- They do! Plus it turns on right away. A big improvement. But you have read the Japanese to understand that. My paper probably does not cover it in enough detail. You can learn more from Talbot Chubb's review:
- I more or less lambasted this latest work in my report, which upset Arata a great deal. However, in his defense, he is battling terrific political opposition, he has virtually no funding. and he never has been a hands-on experimentalist. On the other hand he has dozens of patents and he is one of the most important living Japanese technologists, with an International Medal named after him at the High Temperature Soc., and a building at the National University, and medals from dozens of societies, universities, and the Emperor of Japan. As he says, the Shinkansen wouldn't run if it were not for him. So he is a big gun. He built the first plasma fusion reactor in Japan. If it were not for the political opposition to this field I am sure he would be funded and making a lot more progress than he is. His lab is now staffed by people from Chinese national universities (with whom I can speak in Japanese) so I expect they will make progress on this, although probably not in Japan.

- How has he determined the enthalpy of the incoming H2 or D2? Why isn't there a thermocouple on the feed? If the D2 has to be filtered for helium, how has he determined the filter does not become saturated? How do you credit helium data that is not even shown?

- Paul V. Keller wrote:
- How has he determined the enthalpy of the incoming H2 or D2?
- That would be negligible. The gas is stored at room temperature, at high pressure. The temperature will drop slightly as the gas decompresses coming into the cell, but there is only a tiny flow of gas for 15 minutes in an experiment lasts for 50 to 100 hours. Blank runs with no materials in the cell show no measurable temperature changes.
- Actually, hydrogen has a negative Joule-Thompson coefficient, so it will actually heat up as it is released. See Joule-Thompson effect Kirk shanahan (talk) 16:37, 8 December 2008 (UTC)
- Kirk shanahan wrote:
- Actually, hydrogen has a negative Joule-Thompson coefficient, so it will actually heat up as it is released.
- If you are talking about when the gas is released from the high pressure tank, then yes. That's what I meant when I said "the temperature will drop slightly as the gas decompresses coming into the cell."
- If you mean the temperature will fall during the formation of Pd-H or Pd-D, then no. The formation of a hydride is exothermic. During electrolysis the overall process is endothermic because it takes more energy to decompose the water than you get from Pd-H formation. With gas loading you get heat. Hydrogen release from Pd-H is endothermic; it takes energy to drive the hydrogen out. It only heats up when this is done in the presence of oxygen and it recombines. Otherwise it is endothermic. See Sakamoto et al., ICCF6 and the Storms book, pp. 203, 204 for details.
- This is confusing, so I asked Storms to comment. He explained: "Hydrogen does have a negative Joule-Thompson coefficient. This means that when hydrogen gas expands, it cools. However, hydrogen is not present in PdH as a gas. Consequently, when it leaves, it does not obey the J-T rules. It leaves by forming the gas H2 from H+ on the surface which is desorbed at ambient pressure." - Jed Rothwell
- You (and Ed) are still confused. See the Wiki page Joule–Thomson effect, 3rd line: "At room temperature, all gases except hydrogen, helium and neon cool upon expansion". That means hydrogen HEATS UP when undergoing free expansion. But if Arata was actually running the D2 through a diffuser to purify it, then you shouldn't see the effect. So was he doing that, or did he pre-purify, or what? (This illustrates the problem with demos, they typically are presented with insufficient info to know what is really going on. That's what the literature is for.)
- Furthermore, I note that the vessel pressure was continually rising after the intial loading, up to about 500 psi or so. That will produce some compressive heating, which could explain the observed temp difference. Or a thermocouple failure of some sort might do it too. Kirk shanahan (talk) 15:23, 9 December 2008 (UTC)

- No, it could not. As I noted that would have showed up in the blank runs with nothing in the cell but gas. The thermocouples are not sensitive enough to measure it.
- Or a thermocouple failure of some sort might do it too.
- As I noted already, that is ruled out because the energy also drove a thermoelectric chip, which drove a small motor. This is proof that real energy is produced in the cell. A thermocouple error will not cause a motor to turn.

- As noted in the report, there is a measurable temperature rise from the heat of formation of the hydride or deuteride. The hydride quickly cools to ambient temperature but the deuteride remains warmer than the surroundings indefinitely. Thus, it has to be producing heat.
- Or else an error has been induced during the hydriding process. Kirk shanahan (talk) 16:37, 8 December 2008 (UTC)
- What "error" can cause a thermocouple to register a temperature and also drive a thermoelectric chip? If this is not heat, what is it? - Jed Rothwell
- See here for a nonexclusive list of some candidates: http://www.omega.com/temperature/Z/pdf/z021-032.pdf As to the chip's behavior, I might be able to comment if I had more than your assertion that something happened. I learned long ago not to trust that. Kirk shanahan (talk) 15:23, 9 December 2008 (UTC)
- You seem to be suggesting that something other than energy can make a motor turn. Or perhaps that something other than heat can make a thermoelectric chip produce electricity. Or perhaps that a thermoelectric chip can produce electricity from an error. It is unclear to me what you mean, but please don't try to explain.
- I might be able to comment if I had more than your assertion that something happened. I learned long ago not to trust that.
- Well, there is the journal paper in Japanese and a video of the motor turning from Osaka U., but given your vigorous imagination I am sure you could find a reason to discount them. Let us agree to disagree on this. I will stick with the laws of thermodynamics, and you stay there in cloud cuckoo land. - Jed Rothwell
- As I said in my analysis, I think his calculation of the heat of formation is way off. But it hardly matters, since no heat of chemical formation that normally stops in 20 minutes could persist measurably for 4 days!
- Why isn't there a thermocouple on the feed?
- Not needed, as I said. That part I do not quibble with.
- If the D2 has to be filtered for helium, how has he determined the filter does not become saturated?
- The only way to 'filter He from hydrogen is by using a Pd alloy membrane or the equivalent, or presabsorbing the hyrogen on a hydride bed and pumping out the remaining He. One can get hydrogen absorption blocking by accumulating He at the membrane or bed if that is not taken into account in the design.Kirk shanahan (talk) 16:37, 8 December 2008 (UTC)
- No idea. As I said in my critique, the description of the mass spectroscopy is unsatisfactory.
- How do you credit helium data that is not even shown?
- What do you mean? See Fig. 8 my report (which is from Arata's report).
- I see nothing about quantitative control in your report.
- Bear in mind that my report is not Arata's report. I did not report everything he said. He did do blank runs, as I just noted.
- What would you do to increase the % excess heat by a factor of ten?
- Let it run 10 times longer. Or 100 times longer. There is no evidence that the cell is cooling down. Similar experiments have released 10,000 times more energy than any conceivable chemical reaction, with no sign of petering out. The only reason they stop this one is because they want to analyze the products or use equipment for another test.
- There is also no possibility that the measurements are completely wrong because the temperature difference is roughly 1°C which is dead simple to detect with confidence using these instruments. There is no input power. Plus he sometimes uses the heat to power a thermoelectric chip connected to a small electric motor. (Very small, for something like a camera lens actuator, I think.)
- I have little doubt that these results are real and that this heat is from cold fusion. It far exceeds the limits of chemistry. But I think the experiment could have been done in a more convincing fashion. I expect it is being done better back in China. (Note that Arata's co-author and collaborator Yuechang Zhang is Chinese, and a number of researchers from her university were working in the Osaka lab during the demonstration. I spoke and e-mailed them and Zhang in Japanese. They speak it quite fluently.)

- I wrote that Arata has "dozens of patents." 63 to be exact, with 22 others filed for and now in progress. The first one was granted in 1947.
- I also wrote in response to this question: "What would you do to increase the % excess heat by a factor of ten?" "Let it run 10 times longer." Actually, the percent of excess heat in this experiment is infinite. There is no input after the first half-hour; it is all output. That simplifies the calorimetry! There are many other cold fusion experiments without input, in what Fleischmann calls "fully ignited reactions" (borrowing the term from the plasma fusion people, who have been trying to achieve this condition for 60 years without success).
- I meant you can increase energy just by waiting, instead of deliberately quenching the reaction. To increase power you just increase the amount of zirconium powder. That should work. Arata's previous material scaled up nicely, unlike most other cold fusion reactions. With most cold fusion experiments, if you try to increase power by a factor of 10 you are likely to blow your head off, as you see from the photographs of explosions here:

- Are you (Jed) assuming a constant rate of heat loss to the surroundings, is that how you interpret 1°C? Are you unable to think of anything that might cause a sustained 1°C difference in readings? I do not suppose he ran the experiment again with ten times the amount of Pd and got 10°C difference measured and sustained in the same apparatus. The explosion risk is a sorry excuse. People who knew what they were doin made an A-bomb wihtout killing themselves. The D2 can be fed in slowly to reduce the heating rate at the beginning. Better yet, figure out how to increase the ratio between fusion reactions and chemical reactions within a fixed period of time. If running the experiment longer is your only tool for increasing the ratio, you cannot have looked far.
- One thing I really do not like about this setup is that it relies on the assumption of a constant heat transfer coefficient between the sample and the environment or simply fails to quantify heat generation throughout the experiment. All you really have is that tiny tail, which must be extrapolated for days or weeks before it looks bigger than the chemical reactions that occur within the first few minutes.
- Quantitative does not mean you have one control, yes or no. Quantitative means you show how the heat production varies with parameters. I would like to see a good number of runs, say six or ten, with progressively increasing H2:D2 fraction, showing a smooth variation of all the results with respect to the mole fraction (0.0,0.1, 0.2, ...,0.9,1.0). Another set of runs could show the temperature dependence of the effects. Refrigerate or heat the whole room if you have to. Those results would be a lot more informative than the usual: one run with D2 and one with H2. They are obvious steps for anyone seriously trying to figure out what is going on, as opposed to running the same old dog and pony show.Paul V. Keller (talk) 17:18, 8 December 2008 (UTC)

- Yes. The ambient temperature is stable. The cell temperature is persistently elevated for hours, days or in some cases months. With some cells it is palpable.
- Are you unable to think of anything that might cause a sustained 1°C difference in readings?
- Well, a blatant violation of the second law of thermodynamics would do it, but I don't believe that's possible. I cannot think of anything other than persistent heat that can raise the temperature of lab grade thermocouples and also drive a thermoelectric generator that drives a motor. That has to be an energy source, by first principles.
- The explosion risk is a sorry excuse.
- A friend of mine nearly got his carotid artery cut by an explosion, and Andrew Riley was killed in a conventional chemical explosion of a cold fusion cell, so I would say the risk is real. If you want to try to scale up one of these experiments just be sure I am not in the room. These experiments are dangerous even when they do not work.
- People who knew what they were doing made an A-bomb without killing themselves.
- Obviously cold fusion researchers do not know what they are doing. If they knew they would scale up. The research is entirely experimental without a working theory. It is similar to the discovery of radium which killed Mme. Curie. She died because she did not understand the nature of radioactivity.
- Also, by the way, people were killed developing atomic bombs and fission reactors. The first victim of an experimental accident was in February 1945, caused by using a screw driver to hold two hemispheres apart.
- The D2 can be fed in slowly to reduce the heating rate at the beginning.
- That would not work. You would get lots of nothing until it reached critical loading levels, and then way too much of something. But Arata devices have not shown any sign of going out of control as far as I know, so perhaps the problem is fixed.
- Quantitative means you show how the heat production varies with parameters. I would like to see a good number of runs, say six or ten . . .
- How about several hundred runs, with clear correlations to control factors? See McKubre's data, or the ENEA data.
- Actually, I first developed my CCS theorem when I looked over McKubre's data from the 1998 EPRI report. Unfortunately, while he published 200+MB of data on a CD with the report, none of it was calibration data. Then Storms posted his data and calibration data was included, which is just what I needed to put the final touches on the conventional explanation for apparent excess heat. And by the way Paul, Storms work was with Pt, not Pd, which doesn't hydride at all, so the claims of a required loading are bogus in the first approximation. It may impact surface structure through dislocation loop punching, but the idea that the bulk loading gives CF is bogus.Kirk shanahan (talk) 21:42, 8 December 2008 (UTC)
- with progressively increasing H2:D2 fraction, showing a smooth variation of all the results with respect to the mole fraction
- That wouldn't work. Hydrogen occupies the lattice sites preferentially, drives out the deuterium and quashes the reaction.
- It is easy for you to say "I would like to see" this or that, but people like Fleischmann and Oriani, who have been working with hydrides for 50 years, will tell you that you can't always get what you want, and you seldom know what you've got. A hydride is an incredibly complex and poorly understood system. And furthermore, you -- Paul V. Keller -- don't know much about it, and you should not be second guessing the likes of Fleischmann and Oriani. You should not assume you know how to do this better than they do, or that they have overlooked something obvious.
- You also know way less than Arata, by the way.

- Actually, very few really appear to have been 'hydride' experts. A quick Google Scholar search on "hydride + author:"R Oriani"" for example turned up 9 hits of which 5 could be considered 'hydride' research. For "M Fleischmann" I fot 8 hits, 4 in SERS and 4 in CF, for myself I get 25, with only 1 citation, but with some double-counting, and for a real expert in hydride chemistry, 'T Flanagan', I got 164 hits (counting the citations). The problem with your 'heros' is that they also thought up excuses why the conventional explantions 'just couldn"t' be the explanation for their observations. But they are usually wrong in that. Kirk shanahan (talk) 21:42, 8 December 2008 (UTC)
- To determine whether Oriani is an expert or not, rather than doing a quick Google search, I suggest you read this paper:

- I see, so the writing of one paper qualifies one as an expert in the field? Good, I'll tell Pcarbonn so I can count Scott Little as a CF expert. Seriously, expert status is earned by a block of work in a particular field. Oriani is known as a materials science guy, and not a hydride guy. 192.33.240.30 (talk) 15:11, 9 December 2008 (UTC) - Note added Wiki logged me off so it didn't sign this properly - Kirk shanahan (talk) 15:14, 9 December 2008 (UTC)
- To determine if he is an expert, I would check the Proceedings of the premier metal hydrides conference, the International Symposium on Metal Hydrogen Systems (usually referred to as MHxxxx where xxxx is the year) which is held biannually, or the attendee list of the Gordon Research Conference on Hydrogen-metal Systems (held in the off years when there isn't an MHxxx conf.). He doesn't show up. (Neitehr do any of the other CFers.) Oriani is a respected corrosion scientist and materials engineer, and while he may have knowledge of the hydride field, he is far from an expert. I have more experience in that than he and I don't claim to be an expert! (And before you jump on that, understand that I AM an expert in what I write.) Kirk shanahan (talk) 13:02, 9 December 2008 (UTC)
- I wrote: "That would not work. You would get lots of nothing until it reached critical loading levels, and then way too much of something." Let me add, Dr. Keller, that if you would read an introductory review article or book about cold fusion you would know this. The data from McKubre, Kunimatsu and others makes this obvious, and this data has been available for 17 years. Arata's data also makes it obvious.
- Before you make suggestions or critique this research, I strongly recommend you first acquaint yourself with the ABCs of cold fusion and conventional electrochemistry. Frankly, you make yourself look bad otherwise. No electrochemist or cold fusion researcher is likely to take your suggestions seriously (or even bother to read them) when what you are suggesting is physically impossible, or the questions you ask and concerns you raise were addressed by electrochemists decades ago. Experts in nuclear physics and electrochemistry have worked on these experiments for 20 years. They thought of everything you are now thinking up in the first 5 minutes, because most of them had been working with hydrides for decades.
- The Storms book covers all of the topics you have raised so far, and many others, in detail.

- No Jed, you are incorrect. Storms mentions my 2002 publication where I describe the reanalysis of his data, and then proceeds to give his readers the impression he has refuted my position by discussing his 2006 paper. This is clear misrepresentation as he fails to reference or even mention that I rebutted all his 2006 points in a back-to-back paper in 2006. That is intellectually dishonest and completely misleads thereaders of his book. That is why Pcarbonn tried so hard to not let my edits of the Wiki article stand, since they detailed this for the Wiki reader. With respect to Clarke, yes, Storms has some of his older work referenced, but he fails to mention the one when Brian showed that McKubre couldn't keep air out of his systems. I added that reference to the Wiki article, and fortunately Pcarbonn couldn't find a way to delete it. Kirk shanahan (talk) 12:34, 9 December 2008 (UTC)

- Out of curiosity, where does the EPJ-AP stand among physics journals? I don't have access to Web of Science, but I notice that among in the physics journal category of SCImago[6], EPJ D is 48 of 352 when ranked by SCImago's SJR indicator. II | (t - c) 18:56, 9 December 2008 (UTC)
- I don't know. The EPJ AP theory paper cites this paper in Phys Rev C. : Solid state internal conversion. I would think that this journal meets the request of reliability of most skeptics, and the paper confirms that the controversy is still open. Pcarbonn (talk) 19:56, 9 December 2008 (UTC)
- Eh. That's going more than a bit far. None of the two papers above use the word 'cold' or 'low', although one cites a cold fusion paper. So you have to be pretty involved to even know they're related, which brings an original research problem. II | (t - c) 20:01, 9 December 2008 (UTC)
- Just for the sake of demonstration, while looking over the proposed theory paper, I noted that the authors were considering PdDx (or PdDu as they call it) concentrations where u approaches 2. As far as I know, the best you can do with electrolytic loading is u=1.0-1.1. The Gw curves Kalman, et al show have a breakpoint near that value where the slopes flatten out quite a bit. I am not qualified to judge theory but I can see where that might be a serious problem with their theory, given that there are larger differences at u=1. This is just another example of what happens when you publish in 'obscure' (relative to the paper's topic) journals. A journal with metal hydride scientists on the review staff probably would have caught this problem and had Kalman et al clarify. In any case, since I know this, I would have trouble accepting the results without getting that clarification from a neutral party. There are also many assumptions built into the theory, and all would have to be tested vs. data, but which data? Kalman et al use F&P's 1989 work, and Szpak et al's recent work, but what about the rest? This is the cherry-picking issue I tried to raise in my additions to the Criticisms (theory) Section of the Wiki article, which Pcarbonn block deleted.Kirk shanahan (talk) 21:19, 9 December 2008 (UTC)
Wikipedia is not the place for breaking news
The most recent sections Arata and Zhang's demonstration in Bangalore and 2 new papers on CR-39 in European Physical Journal don't belong on Wikipedia, even a talk page. If has just been published its generally doesn't belong on Wikipedia unless the subject matter is very young as well. Further more this talk page is meant for discussing the article rather then pseudo-peer-reviewing current research in an inappropriate place. Stay on topic.--OMCV (talk) 23:27, 8 December 2008 (UTC)
- Well, Arata's work has been published for 18 years in the peer reviewed literature, and the first paper on zirconium material and this experiment, Yamaura et al., came out in 2002. So it isn't exactly breaking news. I doubt anyone in the field is unaware of Arata's work or the fact that he and several others are investigating Zr and other substrate materials to overcome the problem of sintering with gas loaded finely divided materials.
- But this is one of hundreds of promising approaches and ongoing experiments. Perhaps it is not important enough to include in the article. On the other hand, the article is full of irrelevant and unimportant stuff, not to mention imaginary nonsense cooked up by "skeptics." Replacing some of that garbage with Arata might not be a bad idea. But anyway, Wikipedia belongs to the "skeptics" and know-nothings. They should do whatever they please with the article. No legitimate scientist will contribute.

- Jed, I admit to chuckling at the word 'promising'. It's been nearly 20 years(!!) since the first "promising" experiments.
- As for the article, new research in a field might be mentioned if it broke some new ground. But clearly this stuff doesn't - you've got lists of papers on your site with two decades worth of fantastic and compelling results (if looked at by someone who doesn't realize that novel research (in any field) is little better than alchemy until put through all the filters of science). Anyway, none of these new papers break new ground, they merely rehash old experiments while being considerably less compelling than previous ones. Even you would agree with that.

- Yes. And as I pointed out previously, the replication rate has increased from a few per hundred to 90%; power has increased from a fraction of a watt to ~20 watts in typical experiments; and the ratio of input to output (where there is input power) has increased from a maximum of 3 to around around 40. I consider that dramatic progress, and I think it is promising. Perhaps you do not. For a summary of these improvements see:
- As for the article, new research in a field might be mentioned if it broke some new ground. But clearly this stuff doesn't . .
- I do not think anyone in the field would agree with you. Arata's Zr material is a major breakthrough. The experiment was poorly done, in my opinion, but the material is extremely promising and has many important advantages over anything previously tested, including the other nano materials. As I mentioned, it produces stable heat with no input power; it scales up; it turns on almost instantly; and it turns off quickly too (something many conventional systems such as burning coal cannot do).
- By the way, no one following the field is surprised by this. There has been steady progress in nano materials and Arata has been the acknowledged leader in this technique from the start.

- I certainly don't agree. People should feel free to bring up potential sources on talk page. I can't understand why "if it has just been published it generally doesn't belong on Wikipedia". Generally we want to put published research on Wikipedia, especially if sourced to a reasonably decent journal. Papers in these journals are peer-reviewed before being published. Anyway, this subject matter is relatively young, according to Jed above it is not exactly breaking news. What are your thoughts then? I gather that the CF phycists are waiting for a critical paper from a mainstream physicist -- and they've been waiting for a while. If it takes another ten years, are we supposed to wait for it before discussing their research, especially when that research is published in mainstream physics journals? And a lackluster blog post is evidence enough that it's still nonsense and needs to be presented as such? Why are more professionally worded editorials such the one from Nature India II | (t - c) 05:58, 9 December 2008 (UTC)
- No legitimate science should contribute to Wikipedia in their own field of expertize. As scientists we work on subjects that are in flux involving a lot of original research. We report this work in the proper place, the peer-reviewed journal. Only once assertions are no longer debated are they suitable for Wikipedia in any technical detail. No matter what is argued the field of cold fusion is still in the shadow of P&F as illustrated by the PhysicsWorld.com intro. There isn't consensus that CF is a legitimate line of inquiry. I wish you all the luck in the world bring CF to the mainstream if it has value but it isn't there yet and this is the current context CF should be reported. Again this isn't the place to blog about CF research, especially for individuals with clear conflicts of interest.--OMCV (talk) 06:04, 9 December 2008 (UTC)
- No legitimate scientist should contribute to Wikipedia in their own field of expertise? I don't agree with that at all either. I would hope that some of the people editing this article are up on physics and especially on the specialization, cold fusion. Similarly for all other articles. Most of the medicine articles are edited quite a bit by MDs and most of the economics articles have economists on them. People should be editing where they have expertise. In any case, I still disagree with your contention. If recent research (as this is presumably not, per Jed) is presented neutrally, it doesn't stand for anything other than it is. New, uncertain research. That's not a reason to keep it out. Wikipedia's advantage is that it can move fast, and it thus very up-to-date. If it records breaking news which turns out to be wrong, it's not as if it's a major loss. What are you worried about? People aren't going to be depending upon cold fusion as a medicine. II | (t - c) 06:19, 9 December 2008 (UTC)
- Thanks for demanding that I make my point better. To begin with our standards for science should be no less than our standards for medicine. I'm worried that wikipedia will be filled with poorly substantiated assertions.
- When I say "expertize" I mean the research that the given scientist actually conducts. I would hope a physics contributes on physics subjects, and a nuclear physicists contribute on nuclear physics subjects. But if the scientist is researching the use of a radio isotope as a therapeutic that has previously not been used as a radio therapeutic they should not spend their time writing this up on wikipedia even if they just published a paper. They should submit it to a peer-reviewed journal. On this sort of material the scientist has definitive opinions that are not part of the consensus. By the materials very nature the scientist will be pushing POV. This does not belong on wikipedia and this is what worries me about the current set of editors.--OMCV (talk) 06:40, 9 December 2008 (UTC)
- If we introduced 'new uncertain research" into the article we might as well introduce a trivia section. It will have the same effect as a trivia section in other articles. Trivia are intrinsically detrimental to any topic, especially science topics. More so if they are controversial topics such as CF. In fact we should be serious and selective and err on the side of caution. This field is littered with many false leads. We shouldn't be falling for every promising new breakthrough otherwise we can convert this article to the miracle of the month club. Dr.K. (logos) 06:55, 9 December 2008 (UTC)
- Saying that recent peer-reviewed research is equivalent to trivia is so absurd that there probably isn't a logical fallacy which covers it besides the general 'dubious equivalency'. It does seem like a lot of work for little benefit, but it's not trivia, and the harms seem exaggerated. Anyway, I'm hardly going to edit this article because I don't know anything about cold fusion. But I doubt many Wikipedians do. One of the letters linked to above, incidentally, is a critical letter. I only got drawn into this discussion because it bothers me when people advocate censoring prima facie reliable sources not only from the article page, but from the talk page as well. Those letters in particular look a bit too complicated and primary-ish to be cited in this article, but I wouldn't really know. II | (t - c) 08:08, 9 December 2008 (UTC)
- Imperfectly Informed, my answer covered "new uncertain research". It should not be construed as meaning "peer reviewed research in reputable publications". I understand "uncertain research" to mean the lower grade research published in conference proceedings, obscure journals etc. Incorporating all these highly technical and dubious details and results in the article would clutter it as hopelessly as any trivia section. And in any case, even if any research claims are made in peer reviewed reputable publications, we should wait for the dust to settle as Dr. Shanahan suggests below. Cluttering the article with highly technical information that may or may not survive in the long run, or that may even be refuted by even newer research, does not do any service to the reader. I think we should find a happy medium where we dispense with extreme technicalities and provide the reader with an honest assessment of the state of the art of CF without putting the reader on a roller-coaster ride of high expectations and broken promises on an as-you-go basis, by incorporating the latest and greatest breakthroughs of the day or the week in CF research. Like it or not the CF field has not reached a steady-state yet. We may have to wait out the transients or at least make sure we don't ride every single transient that is offered by the researchers in the field. And this is also for the sake of the average reader. We wouldn't want them to be ejected, during this wild ride, nor should we expect them to be nuclear fusion experts to understand the article. Dr.K. (logos) 16:45, 9 December 2008 (UTC)
- Let's not get excited about peer review. There's a monstrous leap from peer reviewed published papers to verified phenomenon (or even promising phenomenon). This is especially true when we cite from journals of low repute or lax standards (of which there are many). And even more true when it's contrary to most prestigious journals or the position of the best impartial experts in the field. Phil153 (talk) 11:26, 9 December 2008 (UTC)
(unindent) OMCV, I agree that the demonstration and recent papers don't need to be in the Wiki article and thus probably should not be on the Talk page either. As i noted above, demonstrations are not reliable sources, as in the field of CF, they never prove much anyway. Typically a demo is set up to show how something works AFTER it has been well researched and published. The CFers use demos to try to drum up support, and they are typically like Arata's, where you're left wondering just what was actually demonstrated. With regards to the papers in the field, since the field has been discredited for some time, readers shouldn't get excited about 'new' claims, since a) they often aren't (as noted above), and b) they often don't hold up (a la the Paterson Power Cell). In a 'normal' field, recent publications may be more trustworthy, but even there they should still be given some time to let the dust settle a bit. Kirk shanahan (talk) 12:53, 9 December 2008 (UTC)
- Interesting controversy. However to say that wikipedia is not a place for newly published data is absurd. On any other page or in any other topic newly published data is quickly added. Why should physics be different?Doc James (talk) 15:53, 9 December 2008 (UTC)
- I would think in any field that incorporating newly published info without waiting for some reaction from other scientists in the field would be hazardous to Wiki's reliability. Especially so in pseudoscience fields like cold fusion. As noted elsewhere in these Talk pages by several authors, the CFers routinely put out 'new discoveries', only to have their validity questioned later. If the new data you mention seems consistent with conventional wisdom, then you may be safer, but in a field like CF, where the claim is that they are revolutionizing physics, it's dangerous. Further, the mainstream long ago decided the CF saga was over, so almost no one is watching. That leads to a lot of garbage being published that just shouldn't make it. (And by the way, it's chemistry, not physics :-) ) Kirk shanahan (talk) 16:46, 9 December 2008 (UTC)
- Doc James, look at it this way. Jed Rothwell claims above that there are over 3000 reputable, peer reviewed papers on cold fusion published since 1989, proving everything from large amounts of excess heat to all kinds of detections of nuclear products. If the intro contained each of these studies (as it is proposed to contain this one), there'd be a new "breaking research" item in the intro 3 times a week for 20 years.
- Wikipedia is supposed to take a longer term view, while informing the reader of significant developments in the field. A significant development in a rejected field such as cold fusion would be unequivocal demonstration of fusion by a prestigious laboratory, and reported in high profile journal, or the mainstream media. For example, the breaking research of Fleischmann and Pons would obviously be included when it broke. Phil153 (talk) 21:50, 9 December 2008 (UTC)

Electroanal. Chem. a high-profile journal. These are judgment calls. Most of the people who performed these experiments are retired or dead. Finally, most of the journal papers describing these experiments are not available at LENR-CANR.org because of copyright restrictions, but you can find them in our bibliography. All are available at the libraries at Georgia Tech and Los Alamos, which is where we got our copies.

- I really liked the stats. They clearly demonstrate that the "breaking news method" should be better left to CNN and is not recommended for an encyclopedia. It is also clear that we cannot have 3,000 citations in the article. Selectivity with a long term view is the best approach for a field that is still in flux. Dr.K.

My thoughts are that if this article is to reflect the 'state of the art' in CF, updates should be brought up here to be analyzed. Of course, it would be much better to see another review ... II | (t - c) 18:56, 9 December 2008 (UTC)
- The main article should have a section on current thinking in cold fusion research. One thing I noticed from where I participated in this discussion was there seems to be some agreement that even small amounts of H2 dampen the effect. If an agreement is ever reached about which experiments produce gamma rays, that would be deserving of comment too.
- I think Jed and other have carried their point that cold fusion cannot be treated as a pseudoscience topic. The reseach may not be quite trustworthy, but it cannot be dismissed like a few backyard wackos with the latest claims to perpertual motion. The theory may be lacking, but it generally does not delve into the incoherent ramblings littered with science words that you see in pseudoscience literature. I think cold fusion is better presented in terms of the pathological science debate, including all the reasons it might be thought of as pathological science and that it does not warrant funding, but also that sliver of possibility that their might be something to cold fusion research; that there are no absolutes in real science.Paul V.
