Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work indefinitely without an external energy source. This kind of machine is impossible, since its existence would violate the first and/or second laws of thermodynamics. [2] [3] [4] [5]
An engraving of Robert Fludd's 1618 "water screw" perpetual motion machine. The history of perpetual motion machines dates at least back to the Middle Ages. For millennia, it was not clear whether perpetual motion devices were possible or not, but modern theories of thermodynamics have shown that they are impossible. Despite this, many attempts ...
A magnet motor or magnetic motor is a type of perpetual motion machine, which is intended to generate a rotation by means of permanent magnets in stator and rotor without external energy supply. Such a motor is theoretically as well as practically not realizable. [1] [2] The idea of functioning magnetic motors has been promoted by various ...
Newman's Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine. [1]
Joseph Westley Newman (July 2, 1936 – March 6, 2015) was an American inventor and author who developed an "energy machine" which he attempted to patent, but was rejected by the US Patent and Trademark Office on grounds of being a perpetual motion machine. He described this device in a book, The Energy Machine of Joseph Newman.
Schematic figure of a Brownian ratchet. In the philosophy of thermal and statistical physics, the Brownian ratchet or Feynman–Smoluchowski ratchet is an apparent perpetual motion machine of the second kind (converting thermal energy into mechanical work), first analysed in 1912 as a thought experiment by Polish physicist Marian Smoluchowski. [1]
Charles Redheffer was an American inventor who claimed to have invented a perpetual motion machine. First appearing in Philadelphia, Redheffer exhibited his machine to the public, charging high prices for viewing. When he applied to the government for more money, a group of inspectors were sent to examine the machine.
To truly overbalance the wheel (so that torque in one direction is greater than the other) and cause motion, the radius of the spokes would have to be altered throughout the course of the wheel's motion. This would have to be done actively, thus consuming energy in the process — and so the machine would cease to be a perpetual-motion engine.
