Yes.. [snip] The ECAT will need adjustment depending upon the environment into which it operates. This is what should be expected.[/snip] Perhaps it is just me but too little seems to be said about the heat sinking.. It is obviously part of the control loop even if passive in ambient air but the coolant flow variation presents much opportunity for the warm up and ramping up of the thermal output. It is a push pull between heating and sinking like isometrics to attain body resistance. Rossi is trying to firmly control heating and cooling right at the balance point where runaway has initiated but the heat sinking stops it from gaining ground or damaging itself. It would have been interesting if blower fans were running on the destructive test reactor as it came up..my guess is that it would have still gotten just as hot and still self destructed despite all the additional heat being taken away by the fans with no additional current into the resistors once the system got up to the active region.

If the ECAT is allowed to operate in air of roughly the same local temperature, then it should behave the same. I understood that Dennis was suggesting a configuration with much tighter coupling to the coolant. The ECAT will need adjustment depending upon the environment into which it operates. This is what should be expected. My personal opinion is that Rossi used the best approach possible to eliminate the most questions and they still complained.

I think the plan by Brian Ahern is to put the device in an air filled box with a copper pipe wound around the outside or the inside wall, and water flowing through the copper pipe. This would be a large flow calorimeter. I do not think it would be very accurate. I doubt it would be any better than the present calorimetry. There is a photo of a similar calorimeter at Defkalion. - Jed
