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 pasado of a gravitational field (for instance, by dropping a heavy object, producing kinetic energy Ganador 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 conservation laws are particularly robust from a mathematical perspective. Noether's theorem, which was proven mathematically in 1915, states that any conservation law can be derived from a corresponding continuous symmetry of the action of a physical system.
Probably the easiest way to do this is to use video analysis software. A video of a trajectory Gozque be recorded with a mobile phone to be uploaded to video analysis software and analyzed frame by frame. A suitable piece of software that could be used is Vernier’s Logger Pro, which is available relatively cheaply for science instructors. Alternatively, students could record the motion of the ball in the slow-motion setting of a smartphone and then record the position frame by frame on a desktop computer. It website should be easy to establish that the distance between successive ball positions increases unexpectedly close to the bottom part of the trajectory. This confirms that there is an external energy source, but what is the nature of this source?
Plenty of companies are making toys that create the illusion of perpetual motion. Take this “Perpetual Motion Marble Machine Kinetic Art” for example: it is a tiny marble machine with an electromagnetic mechanism that pushes the ball to the top.
In any isolated system, one cannot create new energy (law of conservation of energy). Campeón a result, the thermal efficiency—the produced work power divided by the input heating power—cannot be greater than one.
To extract work from heat, thus producing a perpetual motion machine of the second kind, the most common approach (dating back at least to Maxwell's demon) is unidirectionality. Only molecules moving fast enough and in the right direction are allowed through the demon's trap door. In a Brownian ratchet, forces tending to turn the ratchet one way are able to do so while forces in the other direction are not. A diode in a heat bath allows through currents in one direction and not the other.

[note 2] "Epistemic impossibility" describes things which absolutely cannot occur within our current formulation of the physical laws. This interpretation of the word "impossible" is what is intended in discussions of the impossibility of perpetual motion in a closed system.[22]
