Since the water was driven through the machine with a ~20 W pump, and the thermocouples show no temperature difference when the machine is turned off, I rule out any measurable heat. I was thinking only of a conventional method of transferring energy from the pump to the cell. Then Beene then introduced this novel idea: > What [Jed] misses of course is the one place where he personally has seen > small gain – the Griggs pump, and the cavitation effect.

However, I have seen ultrasound generating equipment of various types, both electronic (Stringham) and mechanical (the Hydrosonic pump). I note that this equipment is not invisible. It is not small. If there is anything like this in the Rossi gadget, that would be readily apparent. So I think we can rule that out. > Well, we could rule it out, just possibly, if we were willing to admit that > conservation of energy might play some role here. > I think the hypothesis is that the heat comes from ultrasound fusion, similar to what Stringham, Taleyarkhan or Hydrodynamics report. I am not 100% sure that phenomenal exists, but I am 100% sure that it requires equipment to produce the ultrasound, and there is no such equipment in the Rossi gadget. - Jed
