Mizuno sent me some graphs of improved calibrations for his ICCF18 paper. I am writing the 6-page proceedings version of the paper. I will incorporate the new graphs and I will add them to the preprint version, which is here:
http://lenr-canr.org/acrobat/MizunoTmethodofco.pdf This makes the results more believable. I no longer have to depend on my rough-and-ready estimate shown on p. 19. He has calibrations for the electrode and the outside wall in two places: (T5) and the base of the cell (T6). The temperature rises in a fairly straight line for T5 and T6 during calibration with a joule heater. He does 10 steps at power levels of 5 W, 10, 15, 21, 25, 30, 33, 41, 46 and 51 W. The temperature difference between the cell wall and the room temperature rises to ~35°C at 51 W for T5. So it is not very sensitive. But with excess heat, all the dots are above that line, scattered around as you would expect with real heat. In one example, at 46 W input, the curve is down at ~31°C but a couple of data points are up at ~49°C. With 51 W of joule heating input, the temperature of the electrode in the center of the cell in a vacuum is ~240°C above room temperature. He says he waits up to 138 hours per step to be sure the temperature is stable. That can't be right . . . - Jed
