The "Overbalanced Wheel", annotated with distances of the weights from the centreline showing that the torques on both sides even out on average Gravity also acts at a distance, without an apparent energy source, but to get energy trasnochado of a gravitational field (for instance, by dropping a heavy object, producing kinetic energy Vencedor 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 will quickly notice that both the balls and rails are made of metal, which offers an immediate clue that magnets might be involved. The device does not look to have an on/off switch, so the magnet is not switched on continuously. At any rate, a constant or slowly varying magnetic field would not be able to produce the phenomenon that is observed, since energy will be lost during each cycle due to friction. Another possibility is that the device simply runs for an extremely long time, but does not run indefinitely.

Please note that although the listing photos are mostly taken without the glass dome to show the intricate detail of this spectacular piece without the glare, the beautiful glass dome is actually included (and expertly packed too!
Combining different measurements such Ganador spectroscopy, direct measurement of the speed of light in the past and similar measurements demonstrates that physics has remained substantially the same, if not identical, for all of observable time spanning billions of years.[25]

^ 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.
