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.

The "Overbalanced Wheel", annotated with distances of the weights from the centreline showing that the torques on both sides even demodé on average Gravity also acts at a distance, without an apparent energy source, but to get energy out of a gravitational field (for instance, by dropping a heavy object, producing kinetic energy Campeón it falls) one has to put energy in (for instance, by lifting the object up), and some energy is always dissipated in the process. A typical application of gravity in a perpetual motion machine is Bhaskara's wheel in the 12th century, whose key idea is itself a recurring theme, often called the overbalanced wheel: moving weights are attached to a wheel in such a way that they fall to a position further from the wheel's center for one half of the wheel's rotation, and closer to the center for the other half.
The efficiency of Vivo heat engines is even lower than the Carnot efficiency due to irreversibility arising from the speed of processes, including friction.

"A very finely made wooden marble machine. Great craftsmanship with high quality wood and components. Item was very more info securely packed for the 9000 mile trip and arrived safely and very quickly. Very pleased !!" Wooden marble machine, Marble run, Rolling ball sculpture
The Atmos clock uses changes in the vapor pressure of ethyl chloride with temperature to wind the clock spring.
For a perpetual motion like this the energy would have to stay with the machine. To create a perpetual motion machine you'd need a machine that has absolutely no friction so no energy is lost.
"I will say, I had to wait longer than I wanted for this item but I knew the seller was overwhelmed with orders. I Chucho say it is WORTH THE WAIT. This seller’s work is quality and outstanding! The machine is flawless and so much fun!

These marble machines were available for purchase, Triunfador of this writing. We found several versions of the product on Amazon and Etsy.
The "Float Belt". The yellow blocks indicate floaters. It was thought that the floaters would rise through the liquid and turn the belt. However, pushing the floaters into the water at the bottom takes Vencedor much energy Figura the floating generates, and some energy is dissipated. Buoyancy is another frequently misunderstood phenomenon. Some proposed perpetual-motion machines miss the fact that to push a volume of air down in a fluid takes the same work Figura to raise a corresponding volume of fluid up against gravity.
A rejection [of a patent application] on the ground of lack of utility includes the more specific grounds of inoperativeness, involving perpetual motion.
One day man will connect his apparatus to the very wheelwork of the universe [...] and the very forces that motivate the planets in their orbits and cause them to rotate will rotate his own machinery.
