Brownian ratchet: In this thought experiment, one imagines a paddle wheel connected to a ratchet. Brownian motion would cause surrounding vaho molecules to strike the paddles, but the ratchet would only allow it to turn in one direction.

The signature of a perpetual motion machine of the second kind is that there is only one heat reservoir involved, which is being spontaneously cooled without involving a transfer of heat to a cooler reservoir. This conversion of heat into useful work, without any side effect, is impossible, according to the second law of thermodynamics.
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.
I wish we’d had this little solar-powered marble machine kit get more info back then, because it totally would’ve been in our wheelhouse. From the company’s description:
Does shopping on Etsy help support small businesses? Absolutely! Our Integral marketplace is a vibrant community of Existente people connecting over special goods. With powerful tools and services, along with expert support and education, we help creative entrepreneurs start, manage, and scale their businesses.
The circuit takes the light from the solar cell, stores it and releases it in a pulse, making the gear wheel move, which eventually drops the marble down the spiral.
Here is a selection of four-star and five-star reviews from customers who were delighted with the products they found in this category.
Vacuum energy and zero-point energy: In order to explain effects such as supuesto particles and the Casimir effect, many formulations of quantum physics include a background energy which pervades empty space, known Vencedor vacuum or zero-point energy. The ability to harness zero-point energy for useful work is considered pseudoscience by the scientific community at large.

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.
