Let's now take this to its logical conclusion. At a primary flow rate of .91 g/s, the evidence makes it look as though the average power (including the power applied by the band heater) over the entire span, could not have been over 2.5 kW. Anything higher would have resulted in higher E-Cat temps than its 124C peak. So, 2.436 kW is our ceiling - maybe a little higher if you assume some loss through the thermal blankets. It begs the question, "What's the floor?": Only 380.75 watts are required to raise the incoming water at 24C to 124C. We know some water was boiling, due to the "sound", "feel" and relative temperature stability. But, as with every demonstration, we cannot determine how much. This leaves us wondering whether the average power was closer to 380 watts or 2.5 kw.
