Another strange possibility to consider – with which to account for lower than expected performance on the active side, and in fact the null side being slightly warmer for a unexpected proportion of the time is this: the null side could be active as well in a lower temperature range.
Otherwise, both sides should be almost identical. If hydrogen, even in trace amounts, collects on the so-called null side, and if the SPP modality is playing a role in excess heat, then both sides can be gainful under different parameters - since a metal catalyst per se is not needed – or stated another way, the dielectric/gas interface on the null sides functions as the catalyst for SPP formation. This possibility becomes far more relevant if there was anomalous radiation, as seems to be the case. From: Craig Haynie Here is a video, queued to the time shortly after the green (active) thermocouple became hotter than the purple (control) thermocouple. The control had been running a couple of degrees hotter, previously. The change-over occurred shortly after raising the power to the point where the temperature went above 1020c. The timing couldn't really have been much better. This occurred at 2016-04-16 02:00 UTC. https://www.youtube.com/watch?v=xUyWnN--u7M <https://www.youtube.com/watch?v=xUyWnN--u7M&feature=youtu.be&t=13188> &feature=youtu.be&t=13188 Craig On 04/16/2016 11:27 AM, Jones Beene wrote: This temperature differential is more meaningful than it seems since some of the excess heat on the active side goes to heat the null side. The basic concept of comparative calorimetry is good, and this ceramic is not a great conductor of heat, but there is a conductive pathway between the two sides, which could possibly have been made less in an improved design. Actually the heater wire itself could be part of the heat transfer problem. From: Craig Haynie The optical imager is typically reading between an 18c and 20c difference.

I hope a post-run calibration shows that when the fuel is removed, the active and null outside temperatures return to one another to within experimental uncertainty. This will be critical to show before concluding anything.

This one is pretty fascinating. At 1000+C they had a delta T of 30C between a fueled and unfueled cell that lasted for hours, until I gave up. At what time in the video did you see this? When I skipped through the video, I always saw the "Outside heater active" (the green line) slightly lower than the "Outside heater null" (purple line). Perhaps you're referring to a delta between different numbers than these? Eric
