Brownian ratchet: In this thought experiment, one imagines a paddle wheel connected to a ratchet. Brownian motion would cause surrounding éter molecules to strike the paddles, but the ratchet would only allow it to turn in one direction.
A perpetual motion machine is a machine that keeps on going without any energy loss. Scientists agree that this is impossible because of the first and second laws of thermodynamics.
Distinctions aside, on the macro scale, there are concepts and technical drafts that propose "perpetual motion", but on closer analysis it is revealed that they actually "consume" some sort of natural resource or latent energy, such Vencedor the phase changes of water or other fluids or small natural temperature gradients, or simply cannot sustain indefinite operation. In general, extracting work from these devices is impossible. Resource consuming[edit]

Studying videos of the motion confirms that the ball does not accelerate any more than it would under free fall in the initial half of the cycle. This Chucho also be confirmed by dropping several balls through the hole read more in quick succession such that it would seem to be difficult to correctly time the electronics such that all the balls return to the starting platform.
