"LENR" no - the evidence as I have seen it includes things other than nuclear reactions as possible cause.
Okay, tell us what can cause deuterium to transmute into helium producing 24 MeV per helium atom? Tell us EXACTLY what "things other than nuclear reactions" can cause this.
Also, what things other than nuclear reactions can generate tritium? Or 10,000 eV per atom with no chemical changes?
You made the claim here. Please back it up with factual evidence from experiments. Your saying "you might have FPHE heat without tritium or helium" is not evidence. It is not true as far as anyone knows. It is counterfactual, or hypothetical. We might have little green winged unicorns invading Atlanta and stabbing people to death with their horns, but we don't. I don't see them, anyway. If they show up, I will let you know.
