J.R. Why wouldn't this cause significant variation in output from day to day? Are you saying one reactor always gets hotter when another cools, so overall they balance?
If you attempt to enclose the complete structure of 24? devices with a single feedback loop then it will be pretty difficult to handle. That is not the way I would approach this problem. I would construct a system around each of the reactors separately. In the scenario I am outlining I would have a temperature sensor that measures the temperature within a single reactor shell. This measurement would then be compared to a fixed and predetermined level. For instance 130 C. Since the water flow rate is assumed constant into the device, its internal temperature will reach the comparison temperature and then the feedback loop will reduce the drive in a linear or other manner. When properly designed, the system will settle at the desired temperature at which point the power fed into the heating mechanism will exactly balance the power being lost as the hot water leaves the enclosure into the piping. When the liquid water exits the enclosure it partially flashes into vapor, but mostly remains water. If this technique is applied to all of the devices(24?) then the total sum of them all is a constant power being delivered to the customer. Now, if the customer needs the overall power to be controlled and constant an exterior loop could be applied. A temperature or pressure sensor would be required to feed information back to the controller where it is compared to a desired power setting. The error should be properly filtered and used to input the changing requirement to all of the 24? units in parallel. Delays would be very difficult to handle in this case, but I suspect it can be achieved with proper design. I also suspect that the data seen thus far is not accurate. Attempting to answer your other questions is going to be difficult without taking that issue into account. I will give it my best. If half the reactors are taken out the power would definitely fall in half without the external loop. Even with it, there is only a certain amount of correction that is possible which would be seen with all of the individual devices running at full drive input power. It is not likely that there is enough reserve to fill in that large of a gap. I agree with all of your numbered points except it is unclear that there is no feedback of any type. For this exercise I am assuming that hot water is the actual phase that exits each ECAT. A small fraction of that water will flash into vapor provided the internal temperature is significantly above the stream supplied to the customer. My calculations are that the volume of vapor to hot water is about 87 to one when the internal ECAT temperature is around 130 C. Can this amount of vapor hide that much water? I really do not know the answer to that question.

The feedback will even compensate for natural variation in heat generation quite well. Why wouldn't this cause significant variation in output from day to day? Are you saying one reactor always gets hotter when another cools, so overall they balance? Especially, why wouldn't this cause the power to fall by half when half the reactors are turned off? It does not, according to Rossi. The power remains almost the same. It is actually higher on some days, as Murray pointed out. Actually, I assume that is because the data is fake. Penon just stuffed some numbers into the table. But if we take it seriously, that seems to indicate: 1. There is no control mechanism. 2. There is a peculiar mechanism that allows reactors to double their output when half the reactors are turned off. 3. It is hot water under pressure, not steam. Then again, even hot water should be cooler when half the power is off. Honestly, I do not think this data is real, and it is probably not worth spending a lot of time analyzing. - Jed
