We need to be careful when we say the technique for reading the temperature only measures photons. When I read the documents from the camera vendor site I came away with the understanding that the detectors that they use in their instruments actually respond to heat directly. The heat is in the form of IR radiation, and the photons from the visual portion of the spectrum would have little effect.
I was impressed by the ability of these camera systems to limit their sensitivities to the IR region of the spectrum. We should not spend too much effort worrying about what color is seen by our eyes. The important information concerning temperature is outside our visual range.

And they should have known in advance, based on the previous results. The reason for this, which you may not be aware of, is that changes in temperature at the high end get multiplied by an equation called the Stefan-Boltzmann Law. Please look at the curve shown on this site http://en.wikipedia.org/wiki/Stefan%E2%80%93Boltzmann_law You can see in this curve - that small changes exponentially increase into huge changes in the power estimate. The technique they are using does not really measure temperature, it measure photon emission and plugs that into a formula. However, had they used a platinum thermocouple or a pyrometer, there would be no problem. They knew this from the previous criticism but ignored it (or else the idea was vetoes by AR). The result is that calibration to 500 only means what it says, the active reactor temperature can be trusted up to this level. Near 1000 however, a small error is multiplied into a huge error. _____________________________________________ From: Randy Wuller Jones: In fairness to this process it also says of the dummy reactor test that “Rossi gradually brought it to the power level THEY requested” (emphasis added). It doesn’t say that the test power level was determined or demanded by Rossi. The fact he turned it off after they had what they wanted is not the same as saying they didn’t test at a higher level “ON ORDERS FROM ROSSI”. I am not saying the test was adequate or inadequate, I am not qualified. But some of what is happening here is not objective and may be driven by other motives, i.e the same as the nonsense you usually see from Krivit.

There is an edited version of the report, in which details like this are removed. Rothwell, no doubt, would chose to only read the edited version. From: Blaze Spinnaker Care to share where you saw this? The dummy reactor was switched on at 12:20 PM of 24 February 2014 by Andrea Rossi who gradually brought it to the power level requested by us. Rossi later intervened to switch off the dummy, and in the following subsequent operations on the E-Cat: charge insertion, reactor startup, reactor shutdown and powder charge extraction. Throughout the test, no further intervention or interference on his part occurred; moreover, all phases of the test were monitored directly by the collaboration They did not calibrate above 450 C and this was not done ON ORDERS FROM ROSSI JR: It does not say that anywhere.
