Actually, I agree with a lot of their report (on Detailed data, mainly). Their COMSOL simulation seems to generate the cyclic "waveform" from the resistive heating only (fig 1). Of course, they don't show THEIR model. It might be in the coupling between the resistors and the ceramic. Conductive? Radiative?
The bright/dark bands are not shadows of the resistors. If could be bright if the resistors are on ... but if the hotcat was running away one would expect the heaters to be off. I think the dark bands are an image of the "slots" that the resistors fit in, with poor thermal contact to the outside. But Levi don't report on the heater power when the picture was taken. On the other hand : The listing of the "independence" is unnecessary. There's a lot of nit-picking -- "how do they know there's nickel ..." (In the title). They complain about testing two (three with November) different systems. I see this as an advantage. The system Levi HAD vs the system they wish they had had. That Levi SHOULD have speculated about the cause. What part of "black box" don't they understand? A lot of speculation on their part about what's IN the black box. What part of "black box" don't they understand?
