cela ressemble à une expérience mal faite du type bien connu effet Peltier sur les métaux, émission thermoélectrique et réactions chimiques sur les électrodes, dans le vide de la pentode, qui vérifie la conservation de l'énergie chimique de dégazage des électrodes et du getter dans la pentode, avec le principe de Carnot, entre le four et d'autres parties du four à T différentes et la température ambiante !!!
Et une université aussi prestigieuse n'a pas à perdre son temps sur ce qui est déjà bien connu, pour aussi peu que 25000$ !!!
une fois de plus dede a montré son incapacité a prendre
le probleme dans sa globalité !
thanks for the contact.
The need for a reputable University to do the $10 experiment is perhaps uncertain except to say that any replication of a violation of the Kelvin interpretation serves to remove the barrier of the status quo which is paralysing energy physics.
The experiment has been done now by a few people but not by a known University.The need for the scientific method to be applied goes without saying for there to be an explosion of interest, but any University doing this experiment will find the response will be almost venomous.
That being said the first thing is to do is to qualify the term $10, the parts are indeed cheap but the time spent and equipment needed to be considered bullet proof are not trivial. However to obviate the need for temperature sensors that are accurate enough to satisfy skeptics I have employed a method of encasing the device (the Radio Tube) in a block of Aluminum (or even better copper or Silver) surrounded by an insulating layer and then inside another block of metal, simple thermal modelling then shows that it is impossible to have a delta T across the device exceeding 0.01K for a easily measured 10K delta T on the outside container (measured by thermocouples in quadrants), the thermocouples used are of course group calibrated.
Having removed delta T across the device it is then necessary to eliminate the other possible sources as have been suggested.
I will deal with them here.
Some have claimed radioactivity of the Tube, given a measured current of say 4uA and a mass of material on the Cathode reasonably calculated at less than 0.1gm we clearly have about 0.001Mole of the relevant material, the occurrence of radioactive isotopes is very small (less than 0.0001%), so that give a total possible radioactive source of 0.00000001Mole, and given a radioactivity half life for the possible isotopes of many years (otherwise the 30 year old valves radioactive material would have decayed to near Zero) we can use a sensible max of 10,000 beta emission per second or say a femtoamp. As the current is uA's then fA's is totally insignificant. In any case if it were radioactive we would not need to heat the tube to see that current.
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 attenuate, so the simplest mode of elimination is to run the DUT unshielded and then rigorously shielded. Further we can add capacitors to short RF so seeing a reduction in the measured current if it is simply rectified RF. Of course other instruments cam be applied to detect such RF as is present. We of course need to run the experiment with a (temporary) shorting link across the DUT to prove the effect is not Seebeck or thermocouple. These are silly as we use identical wires but critics say many things. Of course we need to ensure that the termination at the load are thermally of the same temp so that we cannot be accused of inducing and instrument error, and of course equal at the hot end so no claim of a delta T across the DUT.
I guess I can say a lot more but 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 with unimpeachable independence.
