You are mistaken. Rossi ran his device in public for ~4 hours without input, far beyond the limits of chemistry. He has run in that mode many times in private tests, according to people I know who witnessed these tests. This is known as "heat after death" (HAD) in cold fusion jargon. That is an inaccurate way to describe it, but anyway, if you look up that term you will see that many other researchers have run without input power. Arata supposedly ran that way for weeks. His calorimetry is not good but I think he probably did as claimed. I do not know whether Defkalion has done this. I am sure that Rossi did. I am also sure it really was in HAD mode because the power was definitely off, the cooling water flow was on, so the reactor should have been at room temperature after 4 hours. Yet the video showed it was hot enough to burn a woman who accidentally brushed against it. Also, several people reported the reactor it was full of boiling hot water when they opened it. Rossi has good reasons to avoid HAD mode in normal tests. In the first Elforsk visit, his steel reactor vessel melted. The reaction is not under control. - Jed
