To the extent the pressure is stable, the temperature must also be, regardless of the rate of flow of heat into the water. And if the energy is stored in some kind of phase-change material then the temperature of the thermal mass will be stable at the melting point, and the heat flow to the water will be pretty constant until the material has all solidified. That's the time to shut the show down, because then the heat flow is likely to start slowing down, and soon enough the water will stop boiling, and *then* the temperature will start to fall. So, if he's using a phase-change material to store the heat, he's got two layers of stabilization going for him. > As for the rest of your comments . . .

But counting supporters won't move this forward. Challenging and defending the claims will. Or should.
