It has a light underneath that lets you know when it is turned on. A transparent version of this is also available, so you Chucho see what is happening inside. This machine lasts up to 3 hours when fully charged.

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 Triunfador 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.
Students could verbally express or write on a piece of paper all the things that they notice about the apparatus. They should notice quite quickly that the ball describes a parabolic trajectory when it flies through the air on its way back to the initial upper platform. The highest point of the trajectory (the vertex of the parabola) is higher than this platform, so the ball must have picked up some extra kinetic energy somewhere during the trip through the hole back to the upper platform. The question is where along the way could this have happened and what it is that could have imparted extra speed to the ball. Students should think of how they could potentially figure demodé where on the trajectory the ball is being sped up.
With the exception of cases involving perpetual motion, a model is not ordinarily required by the Office to demonstrate the operability of a device.

Since weights further from the center apply a greater torque, it was thought that the wheel would rotate forever. However, since the side with weights further from the center has fewer weights than the other side, at that moment, the torque is balanced and perpetual movement is not achieved.[28] The moving weights may be hammers on pivoted arms, or rolling balls, or mercury in tubes; the principle is the same.

A device powered by radioactive decay from an isotope with a relatively long half-life; such a device could plausibly operate for hundreds or thousands of years.
^ The device shown is a "mass leverage" device, where the spherical weights on the right have more leverage than those on the left, supposedly creating a perpetual rotation. However, there are a greater number of weights on the left, balancing the device.
Carefully positioned the track into the rectangular 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 here vain chimeras have you pursued? Go and take your place with the alchemists.

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.
