The discussion of color and temperature only mask the glaring reality that an inexpensive way to be certain of thermal gain in the TP2 device is flow calorimetry. I think flow calorimetry with this device at these temperatures would be problematic. For one thing, you could not see the device, which might even be dangerous. I think the present method is better, although it may not have been done right. It should be confirmed with the internal thermocouples. Well, catch-22 they used an internal thermocouple - and apparently took data from a perfect location, which could “see” down the axis of the tube, presumably the hottest place in the system, but chose not to release the data. What excuse can they have - other than the thermocouple data does not support the thermography (therefore the thermocouple failed)? Ahern proposed a calorimeter which would not compromise the integrity of the ceramic tube. Jones
