Right. If we use an identically calibrated Optris camera as the Lugano team used and duplicate their infrared measured image using much less input power than was claimed as output, the MFMP dummy test will have provided negative confirmation of the Lugano results.
HOWEVER ... I just received early information of a dogbone main heater coil test by Ryan Hunt (Hunt Utilities Group, MFMP). The test showed an external temp (thermocouple measured) of 900C with 1107 watts electrical input. Note that the internal temperature was 1196C (this is only important for heater lifetime issues, not the experimental result). This data says that it will take a lot more heat (than 1107W) to get the dogbone to 1200C or 1400C external temperature. The 900C was after 15 minutes. Maybe it would have stabilized a little hotter after a longer time. Compare the 1107 watts to get to 900C in the Ryan's dogbone to the Lugano test report. With an input of 910 watts in the Lugano experiment, the authors claimed a temperature over 1400C. So, if the Lugano reactor was actually above ~850C, Ryan's first dummy replica data suggests that excess heat must have been involved in the Lugano experiment. If the power lost from the device (convection, radiation) goes as the ~4th power of the temperatures in Kelvin, it would take 4.1 times more power for the MFMP replica to go to 1400C, which is about 4500 watts. Obviously this napkin calculation is crude and doesn't take into account those portions of the replica not at 900C or the leads, etc, but it puts the power for 1400C in the same ballpark as the Lugano calculated output of 3300 watts. Another observation is the the internal temperature in the MFMP replica is substantially higher than the outside temperature. This difference may decline with higher temperature, and the difference between inside and outside may have been less for the Lugano reactor because its heater coil appeared thicker and there would have been less alumina for the heat to go through to get to the convection surface. This is not a problem for the accuracy of the test, but may limit just how hot the MFMP test can be run before failure of its internal heater coils. Another interesting prospect is that the LENR heat from the small reaction core could have been better distributed throughout the hotCat mass if the heat was transported by low energy photons (soft x-ray), which would not have been absorbed immediately at the source. This would have allowed the core to remain cooler than the resistively heated experiment now in progress at MFMP.
