[1] [2] Devices allegedly suppressed include perpetual motion machines, cold fusion generators, torus-based generators, reverse-engineered extraterrestrial technology, anti-gravity propulsion systems, and other generally unproven or physically impossible, low-cost energy sources. [2] [3] [4] [5]
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.
Free energy – a class of perpetual motion that purports to create energy (violating the first law of thermodynamics) or extract useful work from equilibrium systems (violating the second law of thermodynamics). [34] [35] Water-fueled cars – an instance of perpetual motion machines. Such devices are claimed to use water as fuel or produce ...
Steorn Ltd (/ ˈ s t j ɔːr n /) was a small, private technology development company based in Dublin, Ireland.In August 2006, it announced that it had developed a technology to provide "free, clean, and constant energy" via an apparent perpetual motion machine, something which is contrary to the law of conservation of energy, a fundamental principle of physics.
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] When the rejection was later appealed, the United States district court requested that Newman's machine be tested by the National Bureau of Standards (NBS).
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 ...
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.
Example of a magnet motor design. The predominantly attracting orientation of the magnets apparently leads to a perpetual rotary motion. A hypothetical magnet motor works with permanent magnets in stator and rotor. By a special arrangement of the attracting and repelling poles, a rotational movement of the rotor is supposedly permanently ...
