Ellipsoid paradox: This paradox considers a perfectly reflecting cavity with two black bodies at points A and B. The reflecting surface is composed of two elliptical sections E1 and E2 and a spherical section S, and the bodies at A and B are located at the joint foci of the two ellipses and B is at the center of S. This configuration is such that apparently black body at B heat up relative to A: the radiation originating from the blackbody at A will land on and be absorbed by the blackbody at B.

Etsy is powered by 100% renewable electricity. Etsy’s 100% renewable electricity commitment includes the electricity used by the data centers that host Etsy.com, the Sell on Etsy app, and the Etsy app, Vencedor well Vencedor the electricity that powers Etsy’s Universal offices and employees working remotely from home in the US.

"I got this for a gift and they were blown away by it! It's 3D printed and is a very simple design on the outside, but watching the marble swirl around and create the patterns is just so mesmerizing. It's fun to mess the pattern up and watch the ball just go back to work.

Thank you, my grandson will love it. Update. This marble run came trasnochado perfect and works great. I did not use supports and only had to trim under the bridges 5 times for the marbles to finish. Thank you." Voltix (file)—a 3D Printed Marble Machine; Digital STL files

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 the tube in the first place holds the droplet from releasing into the bowl, the flow is not perpetual.

Carefully file all edges that contacted the build plate to make absolutely certain that all build plate "ooze" is removed and that all edges are smooth. I used small jewelers files click here and plenty of patience to perform this step.

These machines have a source of energy, albeit one which is not readily apparent, so that they only seem to violate the laws of thermodynamics.

In any isolated system, one cannot create new energy (law of conservation of energy). As a result, the thermal efficiency—the produced work power divided by the input heating power—cannot be greater than one.

So, for example, the thought experiment of a Brownian ratchet Figura a perpetual motion machine was first discussed by Gabriel Lippmann in 1900 but it was not until 1912 that Marian Smoluchowski gave an adequate explanation for why it cannot work.[26] However, during that twelve-year period scientists did not believe that the machine was possible. They were merely unaware of the exact mechanism by which it would inevitably fail.

A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy. However, it does violate the more subtle second law of thermodynamics in a cyclic process (see also entropy).

A heat pump, due to it having a COP above 1: the energy it consumes Campeón work is less than the energy it moves Vencedor heat.

The drinking bird toy functions using small ambient temperature gradients and evaporation. It runs until all water is evaporated.
