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.Personalized advertising may be considered a “sale” or “sharing” of information under California and other state privacy laws, and you may have a right to opt out.
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]
Students could verbally express or write on a piece of paper all the things that they notice about the apparatus. They should notice quite quickly that the ball describes a parabolic trajectory when it flies through the air on its way back to the initial upper platform. The highest point of the trajectory (the vertex of the parabola) is higher than this platform, so the ball must have picked up some extra kinetic energy somewhere during the trip through the hole back to the upper platform. The question is where along the way could this have happened and what it is that could have imparted extra speed to the ball. Students should think of how they could potentially figure trasnochado where on the trajectory the ball is being sped up.

If it is found to be contradicted by observation – well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I Chucho give you no hope; there is nothing for it but to collapse in deepest humiliation.

You can search for "perpetual marble machine" if you'd like to buy one for yourself. Keith Ramsey, a teacher at Bridgeport Elementary School in Indiana, used this machine in a YouTube video to discuss the laws of thermodynamics.
One classification of perpetual motion machines refers to the particular law of thermodynamics the machines purport to violate:[19]
