Indeed that temperature graph is suggesting that thermal inertia could explain the behavior. This would work, if there is no inlet water pumped. But as there is pumped about 5 kg of inlet water into E-Cat during the self-sustaining mode, this would require that there is metallic thermal mass something like in order of one ton. Of course as there is lots of water, requirements are not that high, but still thermal inertia cannot explain the behavior of E-Cat not, by two orders of magnitude. –Jouni
