Perpetual motion12/7/2023 ![]() ![]() The nonexistence of perpetual motion machines, despite centuries of effort to design them, has been used to support the law of conservation of energy. Patent Office has a policy to not examine applications covering perpetual motion machines unless the applicant furnishes a working model. To prove that a particular design of a perpetual motion machine will not work can be very time consuming, and the predictable negative result has never been worth the effort. Wilkins proposed using the magnetic material lodestone, not a superconducting magnet. Was proposed by John Wilkins in the 1670s. The first perpetual motion device using magnetic forces ![]() The details can be quite complicated, but when any design is correctly analyzed it is always found that the energy required to turn the magnetic or electric field on and off, or to move the field from place, to place exceeds the work obtained by the falling weight. The magnet can continually lift and drop the weight. Then, when the magnetic field is turned off or taken away, the falling weight can be harnessed to do useful work. For instance, a weight can be lifted by a magnetic field, perhaps produced by a superconducting magnet, with no power loss. Would-be inventors frequently employ magnetic or electrostatic interactions because these forces are less understood (by them). Friction will always cause such a water wheel to "grind" to a halt even in the absence of doing useful work. The only problem with this device is that it took more energy to pump the water than the entire energy output of the water wheel. The remaining portion of the output could then be used to operate a flour mill. He designed a pump to drive some of the output from a water wheel to recirculate water upstream, which would then run over the wheel again. Robert Fludd in 1618 was one of the first to discover it is impossible to get something for nothing. The idea of perpetual motion, which has been around for centuries, is to make a device that will produce more work output than the energy input-in short, to get something for nothing. ![]()
