Rossi and Focardi LENR Device: Probably Real, With Credit to Piantelli

By  Steven B. Krivit  Where Did the Idea Come From?
From what I know so far, the concept demonstrated on Jan. 14 by Rossi and his colleague Sergio Focardi, a retired physics professor from the University of Bologna, had been discovered by Francesco Piantelli, a retired professor of biophysics with the University of Siena.

The article has a Q&A at the end.   Here's one that is instructive:

Q. Are you claiming this to be “cold fusion” or some new kind of low-energy nuclear reaction?
A. I think that the definition “cold fusion” is wrong in itself. What I claim is a weak nuclear reactions energy. As you already know, I think that there is still much work and study to do on the theoretical field to understand exactly why this reactor works. This path is difficult, because all physics can say to help you is that these reactions are impossible (thank you very much), while in the books, you can find nothing. Also, the more important books (for me, Greiner and Cooks) do not give solutions. We have to invent from the base also in the theoretical field.
