You claimed that it takes months to load the cells, which is also my understanding. They run this glorified voltaic cell for months, and then maybe--maybe--it produces like 50% more energy than they're continuing to pump into it (but only if they roll doubles and use the right brand of super special palladium). Useless at best, and insignificant enough to make one wonder whether something besides "cold fusion" is actually going on.
Remember, what was being done was science, not engineering. So "useless" is problematic.
What if the calorimetry is accurate? These were experts in calorimetry, the world's best. In a reply to Moulton, above, I cite what Hoffman wrote about it. Excess heat was significant. You've sarcastically dismissed what is actually in the literature. The SPAWAR group uses co-deposition, which produces excess heat immediately and reliably, and because it is such a simple (and cheap) technique, they could run many different experiments with many different variables. Come on, One, you should know enough to recognize the significance of correlation between excess heat and helium. Each measurement, independently, can be dismissed, the heat as calorimetry error, the helium as due to leakage from ambient or other contamination. But both together, quantitatively correlated? And reliably so?
In Miles' work at China Lake (US Naval laboratory), they were using Fleischmann cells, and they were getting 12/33 cells, in the series that Storms reports, with no heat. Those become the controls! They measured helium in all the cells, and they found no helium in the 12 control cells. Of the 21 remaining, they found helium in 18. It's a stunning result, One, if anyone is paying attention. It validates both the heat and helium measurements, in fact, leading us to suspect some artifact or error in three experiments; in one of those three, there was apparently reason to suspect the calorimetry. With the other two, there was a different type of electrode being used, and there are a number of possible explanations, but that doesn't matter, in fact. Even not discarding those experiments, the statistical significance is overwhelming.

You can at least understand why most scientists think that cold fusion practitioners are chasing ghosts? Twenty years later, and they're still charging up palladium rods hoping for water to heat up slightly; sorry, but I'm very skeptical. Need something more repeatable (less "fragile," as you put it) to overturn reliable theories.
Fragile is not a synonym for not repeatable. The early techniques were fragile in both senses, replication was effing difficult. I'm now starting to work to set up a company to engineer and manufacture cold fusion demonstration kits (it's never been done), and the first thing Rothwell tells me is forget about it, it's too difficult. Amateurs always fail. Rothwell is pretty cynical, having dealt with twenty years of derision. He's wrong. Amateurs have been able to replicate some of the experiments, and the company I'm designing will not depend on amateurs for design, it will, instead, nail down the protocols to some which work, reliably, guaranteed (or I lose my shirt).
The SPAWAR codeposition technique is 100% reliable. What you are doing, One, is only allowing yourself to recognize
part of the evidence. The part that confirms the reasons for skepticism. I understand it very, very well. You've missed about half of what I've written. Not surprising, that's normal. You overstate the situation with Fleischmann cells. There are groups reporting high replication with them, too. They have figured out how to do it with reasonable reliability. Given that, the "fragility" I report applies to what might happen when attempts are made to scale it up. Personally, I suspect that the Fleischmann technique is an engineering dead-end; but Energetics Technologies in Israel is working on it. Michael McKubre of SRI has published (In the ACS Sourcebook), reports on exact replication of the ET work, being his own and the work of ENEA, Frascati, in Italy. That paper quotes an ET paper. For "the most pronounced excess heat results," he summarizes:
QUOTE
A maximum thermal output power of ~34 W was obtained twice at an input power of less than 1 W. The duration of this episode was approximately 14 h, terminating spontaneously with an integrated energy of electrical input of 40 kJ, and integrated output heat energy of 1.14 MJ.
McKubre summarizes the results: "Of the fifteen experiments [using the ET protocol], eleven produced excess heat at or above the three-sigma experimental uncertainty. As far as we are aware, this level of reproducibility is hitherto unprecedented ...." And here we see what may be a political phenomenon. McKubre seems to be ignoring the work of other research groups. He Jing-Tang, in a review published in 2007 in Frontiers of Physics in China (Springer-Verlag), reports a number of research groups reaching, over the previous year, 100% success. I There are turf battles within the cold fusion community. The idea that they knee-jerk support each other is not confirmed by my observation of discussions and reports within that communityl

Maybe they're suppressing the newer studies on Wikipedia, and maybe these studies do describe actual rigorous results (the coincidence of heat and helium, for example). But at the end of the day, do I believe in cold fusion? No.
The issue is not whether you believe it or I believe it, you know that. As to "newer results," the Miles work was published in the 1990s. Storms reviews the literature in his book, The Science of Low Energy Nuclear Reaction, 2007, and Miles' work was debated in peer-reviewed journals extensively in the 1990s. Storms also covers the work of Bush and Lagowski (1998), Gozzi (many publications, 1993, 1995, 1998), McKubre (2000), Hagelstein (2004) , and he cites fifteen additional studies finding unexpected helium, without a report of the helium-energy relationship. And then he states what is now obvious:
"If the data are accepted, we also need to accept that somehow helium and energy are apparently being created at the same time without generating gamma emission. Or this information can be simply ignored, as it was by many members of the DoE panel convened in 2004 to evaluate cold fusion."
He's right. That panel report actually establishes clearly that cold fusion has reasonable acceptance among the mainstream (one third of reviewers considered evidence for nuclear origin of excess heat to be "somewhat convincing," at least, one-half of reviewers considered evidence for excess heat to be "convincing"), but it also shows that most of the extreme skepticism remaining isn't based on evidence, but on continued attachment to theory. The helium results were clearly ignored by many of the reviewers (examining their individual reports), and thus they ignored the single most powerful collection of evidence not only for excess heat but also for a nuclear origin of some kind. "Fiasco of the century," Huizenga's term, is accurate, but Huizenga was, as the very hostile co-chair of the 1989 panel, part of it. Cold fusion was never rejected through scientific process, it was politically rejected, and very effectively (consider yourself, and consider me up until January!) not on the basis of conclusive evidence, but only a theory of experimental artifact that has become increasingly difficult to sustain. The basic protocols of science were massively violated, and the U. Utah press conference was only the beginning of it. Scientists were pissed about that conference, but, in fact, it should have been irrelevant, it was no reason to reject Fleischmann's work, only to suspect that it was prematurely announced. Which was accurate. I doubt that the neutron findings would have made it into a mature report. Instead, we'd have had better reporting of the heat, we'd not have had the massive and totally premature efforts to replicate what people didn't even have clear reports on, rushed to publication based totally on failure, etc., etc.
The skeptics are just as responsible for this as the attorneys at U. Utah. They also had axes to grind. If cold fusion had been accepted, there would go, probably, their careers, their entire expertise, particle physics, would lose massive funding, hot fusion has been a huge money sink, with most of the money then being diverted into materials science, about which they know little.
Talk about poor payback for input energy! So far, no hot fusion experiment has generated energy payback, to my recollection. Yet billions of dollars have been and are being poured into it, sustaining entire facilities and careers. This is not without effect on opinion, One! It's like the Cab on Wikipedia, it doesn't take a "secret conspiracy," just a common POV and interest.
On the other hand, there are elements of conspiracy involved, if we read the sources, though. Suppose you are a patent examiner who has views favorable to cold fusion and you talk to the single examiner who reviews the "cold fusion" applications? You organize a conference in Washington on the topic, on your own time? There goes your job, based on very heavy lobbying from Park, then of the APS, who bragged about it. The examiner, after years of appeals, was sustained. And many more incidents show a very, very unscientific agenda being pursued with vigor, scientists impeached without cause, losing prestige, funding, and access to the crucial resource of grad student labor. And on and on. And documented in reliable source, academically published.
Really, One, I think you and some others, while very sympathetic in some ways, sometimes, have still had blinders on. I've asked for evidence showing me my errors. No evidence, just repetition of assumptions without evidence.
On-wiki, I examined the evidence presented for tendentious editing, I spent hours and hours. That evidence is preposterous, but was approved by a majority of arbs. The evidence actually included one citation that is ultimately to evidence presented by Enric Naval where he basically opposed what became the decision in RfAr/Fringe science. Literally. Enric's opinion, given before I had touched the cold fusion article, is cited as proof of my tendentious editing. In fact, it shows what I was faced with: consistent and persistent rejection of quality reliable sources based on nothing more than editorial opinion that they are "fringe." Exactly what ArbComm rejected. ArbComm should, in fact, if it were awake, be commending me, not topic banning me or worse.
I understand the argument about working with others; however, you know very well that if a group of editors has taken hold of an article, and are biasing it, and an editor arrives who tries to balance the article, and grow it, using quality sources, the group is going to reject and possibly even harass this editor. It happens. It really happens, in many places -- only the tip of the iceberg has been explored in this case -- with the Cab named, who can back it up with admin tools, and have, not just once, but many times.
People will believe what they believe, without evidence, and it can be extraordinarily persistent, I've seen this for many, many years. It's possible to punch through this (Or, more accurately, sidestep it), but it is not easy. And it has practically nothing to do, initially, with Wikipedia guidelines.

It's my understanding that physicists always hated cold fusionists, even before it was considered discredited, and even at Utah. Seeing these chemists run mere electronic cells and claiming to fuse deuterium apparently stroked them the wrong way.
Yes. They were totally outraged, immediately. What upstarts! However, Fleischmann was world-class, a very respected electrochemist, probably the best. They couldn't just deride him from the start, they had to have a basis. So many rushed out to (dis)confirm. P&F had spent five years working on this, developing techniques, trying to figure out how to make the effect reliably appear, and with larger excess heat percentages, and weren't ready to publish. The physicists -- the APS 1999 review notes this -- had no expertise in calorimetry, Fleischmann's long suit. (The review says that part of the problem was that chemists were playing at physics and physicists were playing at chemistry.) As I noted in an earlier response, the MIT report, considered by many a conclusive refutation of cold fusion, was based on 10 days of electrolysis, and a reported loading ratio that is now known to be inadequate (below 80%; my theory is that the effect only appears, actually, at something like 200% or 400%, which is utterly impossible except as a transient state, very locally, at the surface.) The early negative replications were very sloppy science, but were featured and promoted, and then, publication in the same journals was shut down. Fleischmann was not allowed to respond.
This is the summary I've given: the chemists say this is not chemistry, it must be nuclear physics, and the physicists say that this is not nuclear physics, it must be chemistry.
Once we realize that "nuclear physics" is a field entirely based on plasma physics and an assumption that approximations that work well in plasma physics don't ever break down in the condensed matter environment, and so we gloss "nuclear physicists" as "plasma, particle physicists," what they studied and have experience and expertise with, we can see the possible solution that makes both sides right.
It's not chemistry and it's not plasma physics, it's condensed matter nuclear science. A new field. A disruptive new field, long on experiment and short on theory, as yet, that might destabilize established institutions and careers. Very hot stuff, for sure.
I'm not asking you, One, to "believe in cold fusion." Just to recognize that I'm not blowing smoke, that there are sound reasons, in the sources, for my opinions, and that, until someone actually addresses real problems with the sources, I'm justified in persisting in considering that opinion reasonable (I don't actually "hold" opinions, that is, cling to them, I merely allow opinions with a certain level of support in experience to be an operating assumption. A rebuttable one. I'm actually a skeptic, believing in nothing you can nail down.)
