Maxwell’s Demon
An Energy Conversion Experiment in Contradiction to the Second Law
An Energy Conversion Experiment in Contradiction to the Second Law
We have performed successfully an experiment of energy conversion of a totally new type. Please see the attachment figures. The experiment relates to a special electronic tube, which has two similar and parallel Ag-O-Cs cathodes, A and B, lying on the surface of an insulated base. A and B are very close but well insulated each other, and they eject thermal electrons at room temperature ceaselessly. Over the narrow interval between A and B, the two cathodes may exchange thermal electrons. As the flow of electrons from A to B equals the one from B to A, no net accumulation of electrons occurs in either side. If we now bring a uniform magnetic field to bear on the electronic tube, the thermal electrons will fly only from one cathode to the other, resulting in an electric potential difference between A and B. The potential difference slows down the follow-up electrons as they fly passing over the interval. The electrons are cold down (slightly), causing the whole tube to cold down, too, (much more slightly). Hence the tube will extract heat from exterior to compensate its change in temperature. Accompanied by these processes, there is simultaneously a conversion of energy from the heat extracted from the surrounding air to electric energy of a direct current supplying to an outside load. The maximum current got in the present experiment is 8.0×10-13A, corresponding to a single way flow of electrons from one cathode to the other at a rate of five million electrons a second. Compared to Maxwell’s original idea of an intellectual being, which was supposed capable to interfere or control the molecules’ random motions in a gas, the magnetic field here is really a very skillful demon.
