Massive overstatement. They don't have evidence the process exists in any form.
See the very same Joseph Zawodny speak of "It has the demonstrated ability to produce excess amounts of energy.." in a much more candid way: http://www.youtube.com/watch?v=JBlKc0TaqPs
For a good compilation of LENR related evidence, see this presentation from ICCF-17 in September: http://www.slideshare.net/tylervan/lenr
I followed the links, but the links I couldn't find an article with enough technical details about the experiments. I think that you know more about what is published in the subject, so can you please give me:
* One link to a paper where the excess of energy is clearly measure experimentally, that is published in a peer reviewed indexed journal with a high impact index.
* One link to an article with the technical details to reproduce the effect in the laboratory and measure the excess of energy. (Something like "Experimental LENR for dummies" would be nice.)
I saw the webpage only for a few minutes, and most of the links look like special edition books and conference proceedings. I couldn't find the information I was looking for.
Calorimetric measures are extremely difficult to do correctly, so I would like to see:
) One paper in a well known journal, to be sure that an independent expert in the subject has read it thoughtfully.
) One clear description of the experimental setup, so I could try to convince some friends to reproduce it.

"So far, Larsen still has only a theory and some circumstantial evidence."
In other words, the operative word in the subtitle of the submitted article (used as the submission headline here) is "may." There doesn't seem to be any strong evidence yet that the process described in the article actually produces net energy output.
P.S. I heartily approve of (and have upvoted) the first comment this comment received, pointing out that there isn't even evidence that the speculated process described in the article even exists.
