The data from the September test is great, in this aspect. They did it right. They were filling the E-Cat from a reservoir, and after it was boiling, they gave us the net weight of water in the input reservoir at 21:07, then logged every time water was added, and provided us a final weight.
Water flow inlet Added water during start up, from 18:30: 15640 + 9380 + 9473 + 9959 = 44452 grams. Remaining in the inlet reservoir when the temperature inside the E-cat reached 100°C at 21:07: 8431 grams. Consumed in 2:37 hours (2.62 hours): 36021 grams Flow during start-up: 13.76 kg/hour Added water from 21:07: 8431 + 10089 + 10460 + 6591 + 9960 = 45531 grams. Remaining in the inlet reservoir at 23:10: 22823 grams. Consumed in 2:03 hours (2.05 hours): 22708 grams Flow during boiling: 11.08 kg/hour. Total running time >100°C: 2:05 (2.08) hours Total flow >100 degrees (from 21:05): 23.0 kg IMPORTANT: In the September test, there is no reference to "increasing flow" at the end, they just turn the pump off. This begs the question if the September test had the pump running at full capacity. If so, the rate seen during Septembers operation of 11.08 kg/hr (3.1 g/sec) would be EVEN LOWER during the October test. We know for a fact that the October test, the pump was not running at full capacity, because they specifically stated that the increased the flow during quenching. Obviously, the pump does not put out consistent pressure, as seen in the September test. Was it slowed down for the October test? Was it harder to push through the heat exchanger, across the floor, under the doormat, then up into the drain, than the September test? If the placement of the thermocouples on the heat exchanger cause us to throw out that temperature data, and the E-Cat calorimetry is plagued with phase-change and unknown water flow, just where do we stand?
