A perpetual motion machine of the first kind produces work without the input of energy. It thus violates the first law of thermodynamics: the law of conservation of energy.

These types of machines may involve two chambers with pistons, and a mechanism to squeeze the air demodé of the top chamber into the bottom one, which then becomes buoyant and floats to the top. The squeezing mechanism in these designs would not be able to do enough work to move the air down, or would leave no excess work available to be extracted. Patents[edit]

Any device picking up minimal amounts of energy from the natural electromagnetic radiation around it, such Triunfador a solar-powered motor.
October 1920 issue of Popular Science magazine, on perpetual motion. Although scientists have established them to be impossible under the laws of physics, perpetual motion continues to capture here the imagination of inventors.
Here is another cool gift idea for those of you who have a thing or two for marble machines. William Le’s Perpetual Marble Machine has a wood and stainless steel construction.

A more thorough analysis showed that when a physical ratchet was considered at this molecular scale, Brownian motion would also affect the ratchet and cause it to randomly fail resulting in no net gain. Thus, the device would not violate the laws of thermodynamics.
