It seems we won’t get any further verification data from MFMP in the next days since their Optris unfortunately broke. http://www.e-catworld.com/2015/02/04/live-feed-for-the-mfmp-test/
In any case, if I’m not mistaken the result of the Lugano report would still be a net release of energy, even if the assumed emissivity is wrong, since the temperature based on an erroneous emissivity would only affect the heat convection term. The temperature reading in the thermal camera is basically calculated through the Stefan-Boltzmann Law (‘backwards’) and on the input emissivity. The erroneous temperature and emissivity are then cancelled out when calculating the radiated power through Stefan-Boltzmann Law. Right? I also know that the experimenters at Lugano have continued to discuss the emissivity issue, and I guess they will address that in the upcoming revised report that they have planned to release, hopefully based on follow-up measurements. I have no idea when though.
