It’s a black box.
If it generates more heat than a chemical reaction can, and the fuel is nickel & hydrogen, who cares if it is chemical or nuclear? I would prefer chemical anyways.
This may actually prove fun for Rossi where he could leave out the claim that it’s nuclear and it’s up to his detractors to prove that it’s nuclear in order to shut him down.
Sounds like he's pegging the BS meter.
