History of perpetual motion machines

From Wikipedia, the free encyclopedia.

The history of perpetual motion machines dates as far back as the 8th century, and probably further. Perpetual motion machines are a class of hypothetical machines which produce useful energy "from nowhere" - that is, without requiring additional energy input.

Overview

For millennia it was not clear whether such devices were possible, but the development of modern thermodynamics has led virtually all engineers and scientists to agree that they are impossible. Many have attempted to construct the holy grail of energy production in spite of this.

Some are developed with elaborate machines in the style of Rube Goldberg or Heath Robinson. Some designs may appear to work on paper at first glance, but have various flaws or obfuscated external power sources that render them useless in practice; others remain untested.

Proponents of perpetual motion machines often use other terms to describe their inventions including free energy and over unity machines.

Patents

This sort of invention has become common enough that the United States Patent and Trademark Office (USPTO) has made an official policy of refusing to grant patents for perpetual motion machines without a working model.

The USPTO granted a few patents for motors that are claimed to run without net energy input. These patents were issued because it was not obvious from the patent that a perpetual motion machine was being claimed. These are:

Timeline

Pre-1800s

  • About the 700's Bavaria, the magic wheel or magnet wheel, was basically a wagon wheel that spun by itself. Magnets with lead plates on their backs were affixed to the wheel, like the seats on a Ferris Wheel. Each magnet was attracted to a magnet affixed to the base on the ground. The lead allegedly blocked attraction as each magnet passes by it, so the wheel would keep moving for a time before friction stopped it.
  • In the 13th century, Villard de Honnecourt had a drawing of one in his sketchbook. Honnecourt was a French master mason and architect. The sketchbook is made up of mechanics and architecture. [1]
  • Leonardo da Vinci made a number of drawings of things he hoped would make energy for free. Da Vinci designed a centrifugal pump and the "chimney jack". The chimney jack was used to turn a roasting skewer (a reaction-type turbine).[2]
  • Johanes Taisnerius, a Jesuit priest, worked on a magnetic based perpetual motion machine. Taisnerius's magnetic machine consisting of a ramp, a magnet stone and an iron ball. Pierre de Maricourt had earlier noted such a system which made use of the strength of the magnet stone. This runs into trouble because the path integral of force on a closed loop in a magnetic field is zero.
  • In 1518, Mark Anthony Zimara designed a "self-blowing windmill". Zimara designed a self-blowing windmill that generated power from a set of bellows. The bellows blow the windmill sails round.
  • In the 16th century, John Dee reported seeing a perpetual motion machines during his travels (with a pension from Elizabeth I), but wasn't allowed a closer look.
  • In 1610, Cornelis Drebbel, an alchemist and magician, designed a slow perpetual motion machine that told the time, date, and season. The gold machine was mounted in a globe on pillars and was powered by changes in air pressure (a sealed glass tub with liquid varied in volume through atmospheric pressure changes, rewinding constantly).
  • In 1630, Robert Fludd, English physicist and mystic, proposed many machines. People were trying to patent variations of Fludd's machine in the 1870s. Fludd's machine worked by recirculation by means of a water wheel and Archimedean screw. The device pumps the water back into its own supply tank. [3] [4]
  • After 1635, many English perpetual motion machine patents were granted. Several are variations of a machine developed in 12th century India. An original design is a cable projecting 150 miles into the sky to induct electricity (technology at the time would limit its usefulness, as it weighed 80 tons). [5] By 1903, 600 such patents had been granted.
  • In 1638, Edward Somerset, 2nd Marquess of Worcester developed a perpetual motion machine. He gained a royal appointment as an inventor and builder. Parliament on June 3, 1663, gave a 99-year patent for his "Watercommanding Engine" (a steam engine). Somerset demonstrated many water wheels to Charles I of England, that had something to do with perpetual motion. [6]
  • In 1664, Ulrich von Cranach, a war engineer, of Hamburg, Germany designed a perpetual ball moving machine that did not work in practice. The ball machine had a rotary cannon ball which descended by an Archimedean screw along the periphery of a wheel (like a water wheel), rolled through a track, and then were carried back to the top using an archimedean screw (powered by the ball-wheel). [7] Arthur Ord-Hume illustrated this machine.[8]
  • Johann Bernoulli (also known as Jean Bernoulli) proposed a fluid energy machine. Bernoulli developed the brachistochrone problem in June 1696 and is regarded as a founder of the calculus of variation.
  • In 1686, Georg Andreas Böckler, a German architect, engineer, and author, designed 'self operating' self-powered water mills and several perpetual motion machines using balls using variants of Archimdes screws. One of Böckler's machine used an overbalanced wheel and archimedean screw.
  • In 1712, Johann Bessler, a.k.a. Orffyreus, investigated 300 different perpetual motion models and claimed he had the secret of perpetual motion. Though allegation of fraud surfaced later (from a maid in his employment), investigators at the time, such as the lawyer Willem Jacob 'sGravesande, reported no such fraud.
  • In the 1760s, James Cox (with the help of Joseph Merlin) develops a working perpetual motion machine (known as the Cox's timepiece). The clock device is powered from changes in atmospheric pressure via a barometer. The clock still exists today [but was deactivated due to the clock's relocation].
  • In 1790, Doctor Conradus Schiviers made a belt driven wheel. He also offered a machine in which a several balls powered a water wheel and a bucket-chain (again raising the balls). [9] Others tried to adapt his designs unsuccessful a century later.

1800s

  • In 1812, Charles Redheffer, in Philadelphia, claimed to have developed a "generator" that could power other machines. Redheffer made money on his machine and tried to restrict scientific evaluation of the device. Upon investigation, it was deducted that the power was being routed to the "generator" from the other connected machine. Afterwards, he continued to generate income on similar schemes. Robert Fulton exposed Redheffer's schemes during an exposition of the device in New York City (1813). Removing some concealing wooden strips, Fulton found a cat-gut belt drive. This went through a wall to an attic. In the attic, a man was turning a crank to power the device.[10] [11] [12]
  • In 1827, Sir William Congreve, an English inventor and rocket pioneer, tried a machine running on capillary action. He used capillary action of fluids that would disobey the law of never rising above their own level, so to produce a continual ascent and overflow. The device had an inclined plane over pulleys. At the top and bottom, there travels an endless band of sponge, abed, and, over this, again an endless band of heavy weights jointed together. The whole stands over the surface of still water. Congreve believed his system would go on, supposedly, continually. [13] [14] [15]
  • In 1866, Henry Prince of Britain described the first partially submerged perpetual motion machine.
  • In 1868, an Austrian, Alois Drasch, received a US patent for a machine that possessed a "thrust key-type gearing" of a rotary engine. The vehicle driver could tilt a trough depending upon need. A heavy ball rolled in a cylindrical trough downward, and, with continuous adjustment of the device's levers and power output, Drasch believed that it would be possible to power a vehicle. The invention did not become generally accepted. [16]
  • In 1870, E. P. Willis of New Haven, Connecticut made money off a "proprietary" perpetual motion machine. A story of the overly complicated device with a hidden source of energy appears in Scientific America article "The Greatest Discovery Ever Yet Made". Investigation into the device eventually found a source of power that drove the machine [17]
  • John Ernst Worrell Keely invented, reportedly, a induction resonance motion motor. He is supposedly to have used etheric 'technology'. In 1872, Keely announced that he discovered a principle for power production based on the vibrations of tuning forks. Scientists investigated his machine which appeared to run on water, though Keely endeavored to avoid this. Shortly after 1872, venture capitalists accused Keely of fraud (they lost nearly five million dollars). Keely's machine, it was discovered after his death, was based on hidden air pressure tubes.
  • In 1881, John Gamgee developed a liquid ammonia machine which could operate at the freezing point from vaporation by radiant heat. The resultant expansion would drive a piston. The vapor does not condense to liquid to start the cycle over again, though (thus making the system inoperable). The Navy approved of the device and showed it to President James Garfield.
  • In 1899, J. M. Aldrich was arrested for getting investors for his free energy machine. Aldrich was never convicted. Reportedly, he continued to run his scheme. Ultimately, an interested investor, upon inspection of the device, found a hidden spring.
  • Mark Anthony Zimara of Italy had a huge air-powered machine (basically another attempt at a self blowing windmill). [18] His device is described in Tallmadge G. Kasten's "The Perpetual Motion Machine of Mark Antony Zimara".
  • The American, Horace Wickmam, received a patent regarding a machine with many rotating balls.
  • A Scottish shoemaker, known as Spence, designed a magnetic based machine which later was discredited.
