But according to Rossi's claims in his report, there has to be one. He is claiming 479 kW from the onset of boiling. Yet before boiling, the power is clearly less than 70 kW. So that requires a large and fast power transfer increase.

They do not show that a step increase of the sort Rossi's claims require is possible. It might be possible, but using the sort of thermal mass in his simulations, it would take an input power spike probably an order of magnitude or more above the steady state value and then a perfectly tailored decrease to the steady state value. It's pretty difficult to imagine how to produce such an input profile, or why Rossi would want to produce it. So, it amounts to mental contortions for try to fit Rossi's claims to what is observed, when wet steam and lower power out fits just as well, and requires no such contortions. If it is in fact there, his technique should reveal it. Do you argue > with FEA?

The reference to those graphs helps to understand why a steep increase in power by a factor of 7 in a few minutes is *not* plausible. > Apparently you love to disagree with anything that I state, whether or not > you agree with it. > No, I only disagree with things I don't agree with. But your frequently-expressed, absolute confidence in Rossi having a commercial LENR device, does make it harder to resist expressing disagreement.
