Are we at the "appeal to authority" fallacy yet, Jed?
Nope. Not as long as the people we are talking about really are experts in a discipline relevant to the problem. If you cite experts in plasma physics and say that their cold fusion experiments prove the effect does not exist, that would be a fallacious appeal to authority, because they do not know how to do electrochemistry, as you see from their papers. Or, if you were to cite the opinions of electrochemists regarding the ITER project, that would be a fallacious appeal to authority.
It is not complicated. Is the person you cite a recognized authority in a field relevant to the discussion? In cold fusion that would be an expert in electrochemistry, calorimetry, tritium or helium detection, for example. If so, you have not made a logical fallacy.
Arguing against the who's who of electrochemistry is as troll-like as a troll can be. To take some similar hot-button examples, it is like claiming that climatologists have no business expressing opinions on global warming, or doctors know nothing about obesity and we should defer to the latest fad diet advocate instead.
