Mitsubishi Reports Toyota Replication (December 7, 2012)
Researchers from Toyota Central Research and Development Laboratories performed an independent replication of a Mitsubishi low-energy nuclear reaction transmutation experiment, according to a physicist from Mitsubishi Heavy Industries speaking at the American Nuclear Society LENR session on Nov. 14 in San Diego, Calif.

The physicist, Yasuhiro Iwamura, told the ANS audience that the Toyota researchers confirmed that nuclear changes from one element to another took place without the use of high-energy nuclear physics. Most scientists who have not followed this field closely consider such profound claims inconceivable. Toyota used a LENR deuterium-permeation transmutation method that Iwamura invented.

Iwamura has been working with this LENR method for 14 years. He said that one of his LENR transmutations was closely but not identically replicated by Toyota. Osaka University and Iwate University previously reported similar replications.

So Iwamura is doing research for Mitsubishi.

It is hard to find academic papers about this stuff: Iwamura has at least one from 2002, but it was published in a Japanese journal (in English) which I'm not sure is widely read outside Japan.

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.
