They cost an infinite amount of money. Don't be fooled by imitations. One penny less and they are not perpetual.

*PL. KNOW ABOUT perpetual machines .
*
*Perpetual motion machines are a class of hypothetical machines which produce useful energy "from nowhere" - that is, without requiring additional energy input. Specifically, perpetual motion machines would violate either the first or second laws of thermodynamics. 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. No genuine perpetual motion machine currently exists, and according to certain fundamental laws in physics they cannot exist. The history of perpetual motion encompasses not only energy-creating machines but also methods of exploiting nonobvious power sources, methods, and techniques and devices with no energy loss (or output). This timeline covers those and the discoveries of energy from sources that are "free" (i.e. does not cost anything) for consumption from the forces of nature which are well documented in scientific literature and other more fantastical forces. 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. 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.
*Perpetual motion refers to a condition in which an object moves forever without the expenditure of any limited internal or external source of energy. For example, electrons in an atom or quarks in a nucleus are in a state of perpetual motion. 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. In the macroscoping world, perpetual motion is not possible, because the energy of a particle tends to randomly flow into its neighborhood, such that the original goal of producing an ordered work is lost.

The machines themselves are relatively cheap, but it's the games and controllers where the perpetual motion machine manufacturers make their money.

Perpetual motion machines cannot exist by the laws of physics.

there is no such thing as perpetual machinery....you can get really high efficiency, but there will always be losses to heat. first law of thermodynamics.

I wouldn't. I hear that the payments are FOREVER.
