    en.wikipedia.org/wiki/History_of_perpetual...

    Early designs of perpetual motion machines were done by Indian mathematician–astronomer Bhaskara II, who described a wheel (Bhāskara's wheel) that he claimed would run forever. [2] A drawing of a perpetual motion machine appeared in the sketchbook of Villard de Honnecourt, a 13th-century French master mason and architect.

    Robert Fludd's 1618 "water screw" perpetual motion machine from a 1660 wood engraving.It is widely credited as the first attempt to describe such a device. [note 1] [1] Something for Nothing (1940), a short film featuring Rube Goldberg illustrating the U.S. Patent Office's policy regarding perpetual motion machines (and the power efficiency of gasoline)

    Other rationalizations include references to so-called free energy and zero-point energy, without explaining how these energies are liberated. Others claim that their motors could possibly convert heat energy from the environment to mechanical motion (perpetual motion machine of the second kind).

  7. Newman's energy machine - Wikipedia

    en.wikipedia.org/wiki/Newman's_energy_machine

    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 ]

    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.

    A diagram of Redheffer's first machine. 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 ...
