Ø Being opaque, it means that the Optris camera was NOT measuring the higher internal temperature of the hotCat reaction core or heater coil, but just the surface. Bob, wait a second … just today - in an earlier post you said (correctly) “Because of the porosity of the alumina, the ceramic is a reddening (low pass) filter… … or was that quote from Ryan? Anyway, the problem is not just that the dog-bone is acting as a low pass filter, but moreover the “calculation” exponentially inflates the effect of any radiation that is passed, so that in the end, the reddening is amplified by a fourth power into what could be an artificially inflated temperature estimate. Rossi’s cadre of gullible cheerleaders, here and on E-Cat World, seem to be immune to the basic problem. Rossi never measured temperature – he computed it with a formula that has a 4th power amplification of systemic error. Levi could have used a platinum thermocouple to confirm, and thereby have salvaged something – but he did not. Continuing from your earlier post: “so the light from the much hotter internal heater coils will be reddened as it is transmitted. I have experimented with up to 5mm of alumina ceramic with a red diode laser, and while there is a lot of scattering, there is also a lot of bulk transmission.” Bottom line: “a lot of bulk transmission” can skew the numbers, even a little can. The calculated temperature of the Lugano report could be grossly in error.
