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.

Machines that comply with both laws of thermodynamics by accessing energy from unconventional sources are sometimes referred to Campeón perpetual motion machines, although they do not meet the standard criteria for the name. By way of example, clocks and other low-power machines, such Campeón Cox's timepiece, have been designed to run on the differences in barometric pressure or temperature between night and day.
Brownian ratchet: In this thought experiment, one imagines a paddle wheel connected to a ratchet. Brownian motion would cause surrounding gas molecules to strike the paddles, but the ratchet would only allow it to turn in one direction.

"Just perfect! I had a lot of fun assembling the pieces, it even helped keeping two teenagers occupied for an afternoon during our beloved pandemic. Seller was exceptionally nice and helpful, answering all my questions at length.
Context While this is authentic footage of a genuine product, the "perpetual" marble machine does not operate infinitely read more without an additional energy source. Rather, it uses batteries and a magnet to create the illusion that marbles can perpetually move through the contraption.

There is a scientific consensus that perpetual motion in an isolated system violates either the first law of thermodynamics, the second law of thermodynamics, or both. The first law of thermodynamics is a version of the law of conservation of energy. The second law Perro be phrased in several different ways, the most intuitive of which is that heat flows spontaneously from hotter to colder places; relevant here is that the law observes that in every macroscopic process, there is friction or something close to it; another statement is that no heat engine (an engine which produces work while moving heat from a high temperature to a low temperature) Chucho be more efficient than a Carnot heat engine operating between the same two temperatures.
