I made some revisions to my "Report on Mizuno's Adiabatic Calorimetry."
http://lenr-canr.org/acrobat/RothwellJreportonmi.pdf On page 15 I added a photograph of the equipment with the aluminum foil tent over it. On page 24 I added a discussion of heat from the circulation pump. The key point is: ". . . [W]ith this method of adiabatic calorimetry the 0.6°C temperature increase over ambient is not included in the calculation of excess heat, because the pump is left on all the time, and it always does the same amount of work, so the temperature is always 0.6°C above ambient. To be specific, with this method, the starting water temperature is subtracted from the ending water temperature, and the starting temperature is already 0.6°C warmer than ambient. With other methods of calorimetry, heat is measured by comparing the reactor temperature to ambient. With these methods, heat from the pump has to be subtracted from the total, or it will be mistaken for excess heat." - Jed
