Did you ever run the heating power at the average of the 20 watt pulses over time? For example if the duty cycle were 10 %, a 2 watt continuous signal would achieve that goal. The amount of heat energy deposited inside the calorimeter after a long time would then be exactly the same as for a 20 watt short duration pulse that is repeated absent of internally generated power.
After a few pulses, the slope of the increase in temperature should approximate what is expected due to the heating effect of the higher power short pulse. If I recall, the graphs you included in the report show a relatively smooth upward slope due to the chain of 20 watt pulses. If the slope observed with the average power drive condition is much lower than that due to the large 20 watt pulse chain, then you have pretty good proof of excess power that will be hard to argue against. From what you are saying, I gather that it is difficult to see any significant internal temperature rise when this low average power input is applied. Is that correct? If so, you (Mizuno) have a remarkable system that I would like to review further.

To activate the normal Mizuno LENR reaction it is necessary to apply 20 watts for a short period of time. One would certainly expect the rate of the reaction to drop if much less instantaneous power is applied. You get no reaction at all as far as I can tell. We tried some smaller pulses to confirm this -- both lower in power and shorter in duration. But the ambient noise was so great it is impossible to measure these pulses with confidence, or to know whether they triggered anomalous heat. I don't think they did. Mizuno deliberately picked pulses of this magnitude to produce the trigger temperature. These are the smallest pulses that: 1. Do the job; and 2. Can be measured with confidence. He ran much larger "pulses;" i.e., continuous power for a month, high enough to make the reactor too hot to touch. You cannot do adiabatic calorimetry in that case, needless to say. He used low power pulses in these tests at my request. I wanted to eliminate the noise from input electricity. This greatly reduces the magnitude of the anomalous heat but I think it improves the s/n ratio. It makes the results more clear and the calorimetry easier to understand. Easier for me, anyway. - Jed
