		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 (the Latin term perpetuum mobile is not uncommon) are a class of hypothetical machines which would produce useful energy in a way which would violate the established laws of physics.
		Machines which claim not to violate either of the two laws of thermodynamics but rather claim to generate energy from unconventional sources are sometimes referred to as perpetual motion machines, although they do not meet the standard criteria for the name.

		Perpetual motion refers to a condition in which an object continues to move indefinitely without being driven by an external source of energy.
		Perpetual motion machines are divided into two subcategories (some physicists, including the noted professor of thermodynamics Mark W. Zemansky, include a third), defined by which law of thermodynamics would have to be broken in order for the device to be a true perpetual motion machine.
		The signature of a perpetual motion machine of the second kind is that there is only one single heat reservoir involved, which is being spontanously cooled without involving a transfer of heat to a cooler reservoir.

		Perpetual motion machine proposals are often dismissed by scientists in a manner that appears to the layperson as hasty rejection using dogmatic assertions that such machines are prohibited from working by the "laws of thermodynamics".
		During any virtual (imagined) motion, it is supplying new mass to the portion of chain lying on one side of the ramp exactly as fast as the portion of chain on the other side of the ramp loses mass.
		If an assumed (virtual) motion of the machine results in a final state of the system (the machine and its interactive environment) indistinguishable from its initial state, and zero net work is done on the system during this motion (no work in; no work out) then that assumed motion will not occur.

		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.
