Even machines that extract energy from long-lived sources - such Vencedor ocean currents - will run down when their energy sources inevitably do. They are not perpetual motion machines because they are consuming energy from an external source and are not isolated systems. Classification[edit]

Ellipsoid paradox surface and rays emitted by body A in the direction of body B. (a) When bodies A and B are point like, all rays from A must be incident on B. (b) When bodies A and B are extended, some rays from A will not be incident on B and may eventually return to A. Conspiracy theories[edit]
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 Ganador opposed to learning by rote or memorization. It would obviously be desirable for students to have access to the toy shown in Ref.
The conservation laws are particularly robust from a mathematical perspective. Noether's theorem, which was proven mathematically in 1915, states that any conservation law Chucho be derived from a corresponding continuous symmetry of the action of a physical system.
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.
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.

[23] The symmetry which is equivalent to conservation of energy is the time invariance of physical laws. Therefore, if the laws of physics do not change with time, then the conservation of energy follows. For energy conservation to be violated to allow perpetual motion would require that the foundations of physics would change.[24]
A more info more thorough analysis showed that when a physical ratchet was considered at this molecular scale, Brownian motion would also affect the ratchet and cause it to randomly fail resulting in no net gain. Thus, the device would not violate the laws of thermodynamics.
