I see that ecat.com is claiming that fusing nickel with hydrogen is exothermic. Good luck with that.

If that were true, this fusion would occur in stars. Stars would have higher and higher concentrations of heavier elements (above iron) as they aged.

The oldest stars should be made out of uranium.

Maybe Rossi doesn't understand why stars go nova?

If greater heat is produced by a reaction than goes into starting or maintaining the reaction, then the reaction, whether chemical or nuclear, is exothermic. If there is a catalytic reaction by which hydrogen is fused with nickel, producing copper and excess heat (amongst other things), then the reaction is exothermic.
