The Art Of Engineering For A Perpetual Motion Device.

Perpetual motion is the motion of a device that continues forever in an uninterrupted system.

A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source.

Unfortunally, this kind of machine is impossible as it violates the first or second or both laws of thermodynamics.

There are machines that draw their energy from finite sources such as ocean currents, wind, solar power and others, but these are intermittent and unpredictable.


A perpetual motion machine of the first kind produces work without the input of energy and therefore violates the first law of thermodynamics, the law of conservation of energy.

A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work and therefore violates the second law of thermodynamics, the conversion of heat into useful work without side effects.

A perpetual motion machine of the third kind is usually one that completely eliminates friction and other dissipative forces which is impossible.

Lydell Industries has been designing mechanisms for several years that rely on the rotation of the earth for their power source and therefore do not meet the literal definition of perpetual motion as the earth may stop rotating at some point. We are, however, hopeful that the earth will continue to revolve and we will continue to persevere in our quest to perfect a device that produces continual work output but requiring no apparent input.

We will be posting progress at appropriate intervals.
