[edit] "Cold fusion" stuff

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)
