Harry etal-- With all the discussion of the accuracy of the camera heat determination, why is there not a reference to the thermocouple that was used in the test to monitor the internal temperature. It should have been a good check and in effect calibration of the camera at the higher temperatures. I would tend to believe the thermocouple results over the camera results for internal temperature monitoring in andy case.
I believe the pictures show the thermocouple lead entering one end of the reactor. I may be mistaken, however.

I wonder if others on the list are seeing my new topics being sent to spam. The question that I am asking is whether or not there are clues to the behavior of the temperature and power output correlation from the latest HotCat tests revealed by greenhouse gas behavior of the Earth. The Earth is warmer than it should be according to normal black body radiation effects. We attribute the reason as being due to incoming visible light energy being converted into heat at the surface and atmosphere which is partially captured. Less radiation power is emitted into space than the temperature suggests for a grey body. An inert body is in thermal equilibrium with its surroundings and its temperature is constant. The only way for it's temperature to change is if it's thermal properties change. This is true if the inert body is black or grey bodies. Does the variation in the shape of the spectrum as the temperature increases effectively destroy the calibration established by the dummy HotCat run? Is there a simple way to take the error into account? If an error has been made then the error resides in the estimate of the thermal properties of the HotCat. If no error has been made, then the HotCat is not an inert body it is an active body. As an active body it is able to elevate its temperature by either generating its own energy or absorbing more energy from its surroundings then it is emitting. The latter scenario is considered impossible according to the second law of thermodynamics. Harry
