If not -- if you think the ecat *can* produce intermediate powers -- please try to explain what would come out of the ecat if it were producing 2 kW power (in the Krivit demo). Presumably, if there is no forbidden region, it must pass that power level." I would bet that at this time, and from comments made about 'calibrating' the production units, the input water flow rate is determined by each eCat's reactor characteristics... you can't just use any flow rate with a specific reactor and have it perform as claimed. I.e., they can more or less deposit the Ni powder in a way that scales the reaction rate up or down to some degree, but the flow rate that allows it to run at the cusp of the phase diagram (Point-C on the diagram I posted in the last few weeks) varies with each reactor and thus they have to do some testing to determine exactly what input water flow rate matches the reactors heat production rate and will maintain a fairly constant water level in the lower section of the chimney. If the flow rate it too high then water will build up in the chimney and overflow, if the rate is too low then the water level will decrease and eventually fall below the top of the reactor. The resistance heaters then give them the fine-tuning needed to maintain a constant water level.
