The experts in this case haven't spoken yet and will have their official say.
Let's hope the expert isn't Bill Nye the science guy. Our ostensibly most informed scientists are woefully uninformed about LENR. Even our ostensible LENR scientists are mostly anti-NiH. So yeah, you have a point, there are few expert witnesses who would back Rossi's claims, and most will vehemently oppose them. That doesn't make Rossi's claims wrong.
