Horace, Regarding the input power measurements you may want to re-read the Nyteknik article at http://www.nyteknik.se/nyheter/energi_miljo/energi/article3144827.ece It states: A phenomenon that Kullander and Essén noted was that the curve for the water temperature at the output showed a steady increase up to about 60 degrees centigrade, after which the increase escalated. The curve then became steeper, it clearly had a new derivative. At the same time there was no increase in power consumption, it rather decreased when it got warmer, said Essén. This suggests that contrary to your assumptions, the input power (actually the input current) was monitored and did not increase at the moment of the bend.
The noticed decrease of input current is consistent with a positive temperature coefficient of the band heater resistor. With a resistive load the powerfactor will be close to unity. The current probe was not calibrated, it may have been off by 5%. Another correction to be made to the stated inputpower is that the actual mains voltage in Bologna is 230V i.s.o. 220V. That"s another 5%. It all adds up to an inputpower of maximum 364 Watts, which is by far not enough to boil the water. So the main conclusion from E&K that the e-Cat generates extra heat still stands. Of course you could argue that there must have been an additional powersource, or the poor chaps did not clamp the current meter around the right wire etc, but that seems unlikely. regards Henk
