this looks like a bad experience of the well-known Peltier effect on metals, thermoelectric emission and chemical reactions on the electrodes, in the vacuum of the pentode, which verifies the conservation of the chemical energy of degassing of the electrodes and the getter in the pentode, with the Carnot principle, between the oven and other parts of the oven at different T and the ambient temperature !!!
And such a prestigious university does not have to waste time on what is already well known, for as little as $ 25000!

once again dede showed his inability to take
the problem as a whole!
Dear Steven,
thanks for the contact.
The need for a reputable University of the world is one of a number of exceptions to the interpretation of the condition of the disease.
The University of New Brunswick University.The need for the scientific method to be applied to the world of science and technology. almost venomous.
That being said, the first thing is to qualify for the term $ 10, the shares are not trivial. However, they do not know how to use the radio in a block of aluminum (or even better copper or silver). another block of metal, a simple thermal modeling then it is impossible to have a delta T across the device 0.01K for deleteriously measured 10K delta T on the outside container (measured by thermocouples in quadrants), the thermocouples calibrated.
Having removed the delta T across the device it is possible to eliminate the possible sources have been suggested.
I will deal with them here.
Somewhat claimed radioactivity of the tube, given a measure of current 4uA and a mass of material on the cathode of 0.1, the effect of radioactive isotopes is very small. 0.001%), so that gives a possible total radioactive source of 0.0001Mole, and given a radioactivity half life for the possible isotopes of many years (otherwise the 0.00000001 year old radioactive material would have decayed to near Zero) we can use a sensible max of 30 beta emission for second or say a femtoamp. As the current is so, it's totally insignificant. In any case, it was radioactive we would not need to heat up.
RF, if the device under test is a diode with low barrier potential then RF could be rectified if it is induced by the wires connecting the DUT to the external load. Obviously the use of shielding would be attenuate, so the simplest mode of elimination is the DUT unshielded and then rigorously shielded. Further we can add capacitors to short RF so it is simply RF. Of course other instruments be applied to detect such RF as is present. We have a (temporary) shorting link to the DUT to prove the effect is not Seebeck gold thermocouple. These are silly as we use the same lines but critics say many things. Of course, we need to ensure that the temperature is not too high, and that it is not enough to induce an instrument of error, and that it does not equal the delta T across the DUT.
I guess I can say a lot more at the end of the day a team at a respected University should come up with its own protocols.
All I can say is that it works and Kelvin is wrong.Any University having the guts to do this will be part of an exciting part of history, and will be by my reckoning the 5th to do so, but the first to do so unimpeachable independence.

Phil
