Hi David, Yours was a very thoughtful post. It has taken some time to digest, and I can say I have not fully evaluated the implications across the whole experiment. However, I don’t think something so complicated need be invoked to explain the power spike immediately after shutdown. According to Mats’ data, as the hydrogen was released, the input flow rate at the peristaltic pump was increased – in fact, basically doubled. Since the reactor was boiling, the output at the time was pretty much steam and the reactor pressure was high enough to keep the valve open constantly discharging steam. The immediate effect of doubling the T3 input water rate is to double the VOLUME of effluent from the reactor output. Since the temperature at this time remained well above boiling, the output that was doubled was the volume of the steam. This simple explanation seems sufficient to explain the spike in measured temperature – double the steam volume at about the same temperature and you double the heat output measured at the heat exchanger. Most of this is heat already stored in the E-cat – this is not a burst in reactor output. Do you believe a more exotic explanation is necessary?

Look at the data from 19:22. About 14 minutes before this time the power was shut down, hydrogen eliminated and input water flow rapidly increased. A nice 2.1 degree drop is seen in the ECAT output temperature from the last reading. My thought is that the increased water input flow quickly reduces the rapid boiling within the ECAT and allows the vacuum effect to draw the exchanger hot water into the manifold. This water then leads to a large apparent power increase (Tout – Tin = 8.6 degrees) which is an illusion. Temperature just prior to this (Tout – Tin = 5.3 degrees) yields a lot less power.
