I'm very disappointed with you, Mr Red. Yes I've heard of catalysts and I know what they do, thanks. Now why don't you tell us about those bacteria instead of semantically skirting around just to defend poor old Donuel? Somewhere, in some application or even in some living organism, there may well be a nickel catalyst that can produce methane from something else that contains carbon and hydrogen atoms. I'm actually not interested enough to look into it. I'll take your word, as long as you've told me that you've checked it out. But nothing I know of in the realms of science can convert nickel to methane. I'd love to say End Of, but I have three twisters and turners busting their guts to find fault with that somewhat bald truth. Now either I quit the thread or I question my own sanity. I think I'll take the former path...
