I really wish people would stop discarding the idea of nickel-hydrogen cold fusion just because Rossi has a bad reputation. So I am happy when I see cautiously positive articles like this one.<p>Firstly, those who research this domain are fully aware that cold fusion is impossible according to theoretical physics. But experiments trump theory. And as I have written about it 4 years ago (<a href="http:&#x2F;&#x2F;blog.zorinaq.com&#x2F;?e=61" rel="nofollow">http:&#x2F;&#x2F;blog.zorinaq.com&#x2F;?e=61</a>) the fact is there <i>are</i> experiments conducted by multiple other groups of researchers that demonstrate anomalous heat being produced by nickel-hydrogen cells. Not only this anomalous heat cannot be explained by current physics but there are clues that nuclear fusion is taking place (some nickel atoms being transformed into copper atoms). Unfortunately the controversy about this entire area of research is amplified by the fact that many of these experiments are very hard to reproduce.<p>Research has made some progress over the last 4 years, and my opinion has not changed: whatever mechanism is taking place, it seems to be able to unleash fantastic amounts of energy from very little material. We just need more researchers to look at into it and understand it.
