		As well as being descriptive of motions beyond the scale of human lifetimes, for example in the phrase "the stars in perpetual motion wheeled overhead", the term is commonly used to refer to actual attempts to build machines which display this phenomenon.
		Perpetual motion machines are divided into two subcategories defined by which law of thermodynamics would have to be broken in order for the device to be a true perpetual motion machine.
		Perpetual Motion is a physical impossibility in the world as we know it, but that has not stopped scientists and mystics throughout the ages from persuing it.

		Perpetual motion refers to a condition in which a mechanism provides usable work or energy without the expenditure of any limited internal or external source of energy (known as free energy).
		Perpetual motion machines are a class of hypothetical machines which produce useful energy "from nowhere" - that is, without requiring additional energy input.
		Perpetual motion machines, when hypothesised, are sometimes called free energy machines, though the term energy in that circumstance is being used in a sense outside of the scientific definition.

	Orffyreus (Bessler) and his perpetual motion machine
		The Encyclopedia Britannica describes perpetual motion as "the action of a device that, once set in motion, would continue in motion forever, with no additional energy required to maintain it." Such devices are impossible on grounds stated by the first and second laws of thermodynamics.
		Perpetual motion, although seemingly impossible to produce, has fascinated both inventors and the general public for hundreds of years.
		The enormous appeal of perpetual motion resides in the promise of a virtually free and limitless source of power.

	Perpetual Motion (solitaire) Summary
		The persuance of perpetual motion is to physics and mechanical engineering what alchemy is to modern chemistry, which is to say that it is seeking after the unrealizable.

	Perpetual Motion Machines: Interesting Thing of the Day
		But the point of building a perpetual motion machine is typically not just to get something to stay in motion, but to do work of some sort—propel a vehicle, power a mill, heat your coffee, or run your computer.
		And if there were a device that converted electricity into motion, and then used that motion to drive a generator producing more electricity (to keep the cycle going indefinitely), that would violate the second law, which predicts that eventually the loss of energy due to inefficiency would cause the machine to stop.

	Perpetual Motion
		Perpetual motion machines are ordinarily of the first or second kind.
		Perpetual motion machines of the second kind operate by extracting energy at some point in their cycle, use it for work, yet have everything return to an original state unchanged at the end of the cycle.
		A perpetual motion machine of the third kind is one that has a cold reservoir at absolute zero.

		No-one has ever built a perpetual motion machine, therefore there must be a law of conservation of energy that forbids such machines.
		Of course, few would dispute that Helmholtz was justified in his historical assessment: every attempt at perpetual motion before 1847 had indeed failed, just as though some natural barrier existed to achieving a self-sustaining mechanism.

		To prove the experiment I wired the coils (when the device is in a perpetuating state, the coils can be manipulated in any way and even taken off) to a light bulb and broke the circulating current, demonstrating to the professor the amount of light that would flash in the bulb.
		Perpetual motion of the first type refers to an apparatus whose efficiency exceeds one hundred percent-that this type of mechanism violates the soundly established principle of conservation of energy, which is embodied in the first law of thermodynamics "A perpetuum mobile of the first kind cannot exist."
		The article continued to describe perpetual motion of the second kind as referring to a mechanism that removes heat from a source and then converts this heat fully into other forms of energy, and that although this process suits the principle of conservation of energy.

		He had with him a miraculous perpetual motion machine that required no source of energy to run.

		However, the inspector noticed that the gears of the perpetual motion machine were worn in the wrong direction if it was really powering the other device.
