I am referring to the famous HotCat test where the three scientists wrote a nice long report. I believe it was the last demonstration before the year long test. Perhaps someone can find the exact reference, but it has been a while now. Jed, give me a hand here.
It was well publicized and included a several day period during which the output was set to a fixed power. During the test the input power being supplied to the device was slowly dropping as presumably more excess power was being generated. A temperature sensor was attached to one end of the device which fed back that information into his control box. Does this ring any bells? I suppose we can search further if you really doubt that the test took place. I feel a bit lazy at the moment. Dave -----Original Message----- From: Stephen A.

Why would he hire control experts if that were not the reason? I don't know why he does anything. I was asking for a specific assertion. AFAIK he never made such an assertion. Do you think that anyone would have taken him seriously for any significant period of time had he not discussed that issue? People who looked seriously at his output power curves stopped taking him seriously years ago. So, this objection is not relevant. It seems a bit unfair for anyone to state that Rossi runs his systems open loop especially when you should recall the HotCat test performed by respected scientists. They took notes which clearly showed the input power being throttled back in time as the output power was maintained at a constant level. This is the obvious finger print of negative feedback. No, I recall no such thing. In fact Rossi did indeed supposedly run his demos open loop four or five years ago. He set the input power to a fixed value and then showed the output power ramping up to a value several times the input. And this appears to be the same, exact system, just replicated many times. So, the assumption that there's feedback in it now seems unsupported, just like the assertion that there's a recirc pump which is pulling the pressure below 1 atm at the other end of the steam pipe. And no, I don't recall any clear report by independent parties that the input power was definitely throttled back while the output power remained fixed. Please give a specific example -- I really recall no such thing. There were a handful of more or less independent tests; presumably you have one in mind. Which?

Has Rossi actually described in some reasonably clear way, rather than just giving a handwave to a leading question about feedback? Where does this information come from? What was the feedback parameter (i.e., what temperature probes were used) and what, exactly, did it control, and how? I know a lot of people have assumed this, but I have never seen it stated as a fact, and I have never seen it claimed by Rossi.
