Talk:Palladium hydride

"Cold fusion" stuff

I see someone says in the first paragraph "No cold fusion experiments have achieved conclusive positive results, however, and the theoretical ability of palladium to accomplish this is in dispute." IMHO that is a personal and uninformed opinion. There are several pear reviewed papers by the Space and Naval Warfare Systems Command (SPAWAR)group, Peter Hagelstein at MIT and many others that can be found at lenr-canr.org. When MIT labs did the original tests in '89 they actually found excess heat but the report was improperly modified by Bob Park, who's Plasma Fusion Center was having $20M with held as a result of the announcement by P&F. Caltech was also having 10's of millions of dollars with held. They also showed excess heat but only considered fast neutrons as a signature of fusion and there for concluded that there was not indication of fusion. They also have continued to receive 10's of millions of dollars every year for there hot fusion program. The apparatus at Brillouin Energy has been examined by a PE specializing in calorimetry, PhD's in Chemistry, Electrochemistry, Nuclear physics, Nuclear energy, Nuclear fuel, Electrical Engineering. All agree the measurements are conservative. We have produced more than 2W thermal out for every 1W of electrical in and the device shown is not even complete yet.(begining the elemination of carbon from our energy diet.

The article mentions "Cold fusion" as a usage of "PdH", but I have a lot of objections to that:

1. "Cold fusion" per Pons and Fleichmann is now called "CANR", Chemically Assisted Nuclear Reactions, "Cold fusion" is now used for some considerably hotter nuclear reaction,
2. Instead of giving CANR as a "main usage" in the introduction, it should be mentioned somewhere later and thus given a less important position - inversely, the usages in the section Uses of palladium hydride could be put into the introduction,
3. It should somewhere (initially) be stressed that "Palladium hydride" is actually not a chemical compound, but a solid state solution.
4. Dealing with whether CANR works or not, should be dealt with in the appropriate article, even though fringy, quite a few sources says CANR actually works, but under very unpredictable conditions - I don't know, but as long as that's the case, we might be a little careful with claiming "yes!" or "no!" on the Wikipedia?

The article lead mentions cold fusion ( a very hot wiki topic I notice!) and says that palladium hydride has been used in cold fusion experiments (which when added was a "hot topic" - perhaps it should be dropped to a historical note however IMHO it shouldn't be lost). The main industrial use isn't mentioned in the lead perhaps it should be.

CANR is probably a better term than cold fusion but certainly not so widely known. I agree that this article shouldn't get "involved" with the cold fusion debate, and shouldn't state so explicitly that cold fusion doesn't work. I would support a link to the cold fusion article with a caveat to avoid giving the impression that cold fusion is a universally accepted phenomenon.

Yes I agree it (PdH_?) is best described as a solution at least for low concentrations of atomic hydrogen. The article is deliberately vague- blame me. Concentrations of H where PdH becomes semiconducting may indicate that the simple solid solution description is inappropriate. I know of no research on that phase that states unequivocally what is going on. If you have a referenced source, that would really help the article.Axiosaurus (talk) 18:28, 2 January 2008 (UTC)

Room-temperature superconductor

PdH is a potential Room-temperature superconductor. How did this manage to go unmentioned? —Preceding unsigned comment added by 166.70.80.198 (talk) 02:02, 16 January 2010 (UTC)

"CANR", Chemically Assisted Nuclear Reactions

A "CANR", Chemically Assisted Nuclear Reaction' would, like any other nuclear reaction, produce nuclear reaction products, high energy particles and maybe X-rays. So far these do not appear to be reported. Such a reaction and its associated products would be a major discovery, it would not be hidden for long. --Damorbel (talk) 21:34, 3 February 2022 (UTC)
