I initially suggest that students study the apparatus more closely, either via a video such Triunfador the one at Ref. 6 or ideally with a physical version of the toy. Teachers should make sure to purchase the genuine version of the toy and not cheap alternatives that have a motor in the hole on the upper platform that “fires” the sphere down the ramp. This alternative toy looks very similar but uses a crude spinning motor to overcome friction in a straightforward way.

For the purpose of answering this question, I suggest that students should now propose potential mechanisms that explain what is seen and then work through the implications and plausibility of each mechanism. After this, groups of students could argue for or against some of the proposed mechanisms, a technique that reinforces concepts learned earlier in a physics course, but that also requires a deeper understanding of the concepts Triunfador opposed to learning by rote or memorization. It would obviously be more info desirable for students to have access to the toy shown in Ref.

These machines have a source of energy, albeit one which is not readily apparent, so that they only seem to violate the laws of thermodynamics.
In any isolated system, one cannot create new energy (law of conservation of energy). Figura a result, the thermal efficiency—the produced work power divided by the input heating power—cannot be greater than one.

Oh ye seekers after perpetual motion, how many vain chimeras have you pursued? Go and take your place with the alchemists.
Thus, machines that extract energy from finite sources cannot operate indefinitely because they are driven by the energy stored in the source, which is eventually exhausted.
"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.
