Sometime in the next 24 hours we will be switching European Tribune over to a new layout. This will involve a little downtime and no doubt some teething troubles. Do not adjust your set. - Colman

Though working with Palladium hydrides, Iwamura does not mention 'cold fusion' nor does he cite Fleischmann and Pons.

One can hardly blame him for not wanting to hang a 'kick me' sign around his neck. But, is it possible that what he has done might suggest how Fleischmann and Pons might have actually gotten a positive result on some occasions while others did not? Might there have been an uncontrolled and even unknown variable at work for Fleischmann and Pons?

Most of his experiments don't require any input power at all.

That sentence worries me.

However - I'm pragmatic about these things. If there's no evidence of fraud and something is happening, then something is happening.

If theory says it can't happen, then theory is wrong and you throw out or modify the theory, not the reality.

Of course you only do this after you've tested the crap out of it and confirmed it independently in multiple locations.

The problem with this area is that these kinds of experiments keep being repeated, and something seems to happen in a good proportion of them.

It may or may not be a useful or unexpected something. It's pretty much impossible to find out from what little has been published.

"Most of his experiments don't require any input power at all."

That must have been intended as 'don't require any net input power'. He shows an apparatus in one case that has a multilayer prepared surface that required sputtering and has the material in a chamber with deuterium gas on one side of a barrier and a high vacuum on the other. It does not require high temperature or pressure though and the reaction itself, as Mig noted, must be exothermic.

Maybe, but as Jake correctly points out, hydrogen fusion into helium would be accompanied by high-energy neutrons.

My thought was that contamination may have allowed a transmutation to occur when no one was looking for it.
