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.

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]

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, click here Figura 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 base of the device confirms that the contemporáneo mechanism is slightly subtler than this and involves sensors.
