True, but I don't think that's going to be very relevant for the longer runs (it's on the order of normal chemical reaction energy, and I think at most about 10% of the electrical heater energy in this case). (Assuming 50 cc, full of Ni powder with a density of 5 gm/mL, and a chemical energy of 1 eV / Ni atom). According to http://www.nyteknik.se/incoming/article3166569.ece/BINARY/Report+test+of+E-cat+28+April+2011.pdf the power was 65 W when the control unit alone was on, then 378 W when the heater was turned on. I assumed (perhaps incorrectly) that the 65 W to the control unit doesn't end up in the device. That leaves 313 W. If the 65 W also ends up in the device, then the temperature "would" be 108 ºC (if the boiling point of water were higher). IOW the electric heater alone could heat all the water to boiling point, and produce a little steam. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
