The principles of thermodynamics are so well established, both theoretically and experimentally, that proposals for perpetual motion machines are universally dismissed by physicists. Any proposed perpetual motion design offers a potentially instructive challenge to physicists: one is certain that it cannot work, so one must explain how it fails to work. The difficulty (and the value) of such an exercise depends on the subtlety of the proposal; the best ones tend to arise from physicists' own thought experiments and often shed light upon certain aspects of physics.

"Gorgeous kinetic art wheel. Fast delivery and excellent handcrafting. All my friends,visitors and me are completely fascinated. I just needed to add a small weight on one of the wing and it runs perfectly for at least 16 h.
Similarly, rays originating from point B that land on E1 and E2 will be reflected to A. However, a significant proportion of rays that start from B will land on S will be reflected back to B. This paradox is solved when the black bodies' finite sizes are considered instead of punctual black bodies.[46][47]
The toy that I have mentioned seems to be a relatively plausible example of perpetual motion. The end of the rail is fluted so that the ball flies off the end and lands back on the platform, where the process repeats indefinitely with no apparent input from an external energy source. Figure 1 shows a view of the device from the side. One Chucho see that the ball slides down a pair of rods that are placed side by side.
A capillary action-based water pump functions using small ambient temperature gradients and vapour pressure differences. With the "capillary bowl", it was thought that the capillary action would keep the water flowing in the tube, but since the cohesion force that draws the liquid up more info the tube in the first place holds the droplet from releasing into the bowl, the flow is not perpetual.

I wish we’d had this little solar-powered marble machine kit back then, because it totally would’ve been in our wheelhouse. From the company’s description:

The first law of thermodynamics is the law of conservation of energy, which simply states that energy cannot be created or destroyed, but rather is transferred.
In some cases a thought experiment appears to suggest that perpetual motion may be possible through accepted and understood physical processes. However, in all cases, a flaw has been found when all of the relevant physics is considered. Examples include:
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, Triunfador 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 saco of the device confirms that the actual mechanism is slightly subtler than this and involves sensors.
