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.

Thank you, my grandson will love it. Update. This marble run came trasnochado perfect and works great. I did not use supports and only had to trim under the bridges 5 times for the marbles to finish. Thank you." Voltix (file)—a 3D Printed Marble Machine; Digital STL files

"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.

"Just completed the marble run. I had to make a couple of adjustments & now it works great. The documentation on the other hand - needs improvement. Some of the illustrations aren't clear. The photos of the wood components are a nice touch - but the color of the wood blends into the background - the white paper of the document. Note for other customers - the spots you place a few of the upright supports in - there's a little wiggle room - ie, the piece is slightly smaller than the placement read more spot.

Carefully positioned the track into the cuadrilongo hole in the bottom assembly, noting the rectangle is offset to provide clearance for the track insertion pin.

Oh ye seekers after perpetual motion, how many vain chimeras have you pursued? Go and take your place with the alchemists.

[note 2] "Epistemic impossibility" describes things which absolutely cannot occur within our current formulation of the physical laws. This interpretation of the word "impossible" is what is intended in discussions of the impossibility of perpetual motion in a closed system.[22]

Those of you who have taken a physics course or two know that perpetual motion machines are impossible to make Vencedor they violate the first and second laws of thermodynamics.
