You Gozque search for "perpetual marble machine" if you'd like to buy one for yourself. Keith Ramsey, a teacher at Bridgeport Elementary School in Indiana, used this machine in a YouTube video to discuss the laws of thermodynamics.
By timed electronics, the electromagnet is switched off before the ball reaches the lowest point in the ramp, which allows it to continue around the rest of the ramp, where it is launched back to the starting platform with the extra speed that it obtained when the electromagnet was switched on. The process is then repeated indefinitely. This explanation is incorrect, however, Ganador the extra kinetic energy imparted in this way would be insufficient to allow the ball to travel all the way back to the starting platform. The presence of a CPU in the almohadilla of the device confirms that the actual mechanism is slightly subtler than this and involves sensors.

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 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.
