Perhaps with this device that is the case, but with previous reactors he often obtained much better ratios, and an infinite ratio, with no input. On Oct. 7, 2011, he ran for 4 hours without input. People expressed doubts about these previous tests, because the instrumentation was not good and because Rossi acts suspiciously at times. I think it is time to put aside these doubts. I have not read this new paper carefully, but I believe it puts to rest all doubts. It is not possible that Rossi was lying or faking in previous tests and only now he has something real. No one can go from nothing to something as dramatic as this in one step. It is time for the skeptics to admit they were wrong about Rossi. (Real skeptics, I mean, not the pathological ones.) There is no doubt that some of his tests did fail. He says so himself. In a few cases, such as with NASA, he said the reactor was working but they disagreed. The fact that it did not work at times does not in any way mean that it never worked. A real experimental device works sometimes but not other times. All of the cold fusion reactors I know of, made by F&P, Mizuno, McKubre and others sometimes failed and sometimes worked. Frankly, at this stage in the development of the cold fusion, I would be suspicious of a device that always works. I do not think the input to output ratio (COP), has ever been significant in any cold fusion experiment. It reflects limitations of the test equipment or the conditions of that particular experiment. Many experiments must be run at sub-optimal temperatures and other conditions because laboratory test equipment does not work at high temperatures, or because it is difficult to measure heat at high temperatures. These limitations have no bearing on the technological potential of cold fusion. Once people learn to control the reaction, I have never had the slightest doubt they will be able to achieve any temperature up to the melting point of the host metal, and any COP they find convenient. This is simply *not an issue*. Many tests have shown that cold fusion can be "fully ignited" (self-sustaining). It may be more convenient or safer to run it with input power, but input power will be a small fraction of output with any technology. - Jed
