With a laboratory calorimeter, you calibrate extensively to measure losses. You establish the "recovery rate" is, say, 95%. So if you input 1 W and there was no excess heat, you would measure ~950 mW of heat coming out. I would conservatively assume the noise is +/- 50 mW for a typical water-based calorimeter, especially at low power. You could not be reasonably confident there is actual excess heat until you measure ~100 mW excess; that is, 1.000 W in, 1.050 output. I wouldn't believe that myself. I would hold out for ~1.100 W. > 1mW is a big deal. > 1 mW is far too small to measure with most conventional water-based calorimeters. Martin Fleischmann could do that, but no one else could. There are microcalorimeters that can measure micro-watts or even pico-watts. They do not work well with cold fusion. A few experimenters have used them. - Jed
