al months ago, after a period of intensive study consisting of obsessive compulsive all-night-long literature searches, I reached the conclusion that ultra-high-power LENR+ (or whatever funky term you want to use) is likely a ubiquitous phenomenon that a multitude of researchers have witnessed.
I don't know what you consider ultra-high-power. If you mean power over 100 W, then practically no one has witnessed it. Except when Fleischmann and Pons' early device blew up. Mizuno and others have seen heat after death ranging from 20 to ~100 W.
Mizuno probably saw ~480 W at one point. See p. 11:
If you have in mind something like what Rossi claims, with a kilowatt or more, there are no credible reports of that. If "multitudes of researchers" had witnessed such a thing, they would have recorded the data and reported it. They would not keep it secret. They do not hide good results. On the contrary, they often report high heat that turns out to be a mistake, and is actually zero heat.
