When the nickel "fuses" with the hydrogen, a new isotope (or element) is created.I'm not talking about the operation of the E-Cat. I'm talking about Rossi's claim about preparing his "catalyst". Rossi is claiming that he is, somehow, enriching certain isotopes of Nickel before it is suitable to be used in the E-Cat.
Note that although he claims to have "enhanced" Nickel, the reports of the analysis of his "before" and "after" fuel samples showed no signs of unusual isotopes or elements. They only showed the natural isotope ratios of both Nickel and Copper, which is what we would expect if there were no nuclear processes occurring.
As far as I know, Rossi has not released the actual report, which is typical of him. It would go a long way toward proving or disproving Rossi's claims.
Another silly claim by Rossi.
