Hello, there was some discussion about this alleged perpetual motion machine. It was elegant, perhaps too elegant, and therefore it is probably a fake.
*Evolution of perpetual motion* http://www.youtube.com/watch?v=zqG-TL0WnjE The idea is however simple and understandable and I refuse to believe that it is impossible, because I do not see how it could violate the quantum mechanics and the conservation of *information*. As we know, that it based on improved version of SMOT ( http://en.wikipedia.org/wiki/Simple_Magnetic_Overunity_Toy). SMOT itself is a failed perpetual motion machine, because no one has managed to return the iron ball back to the starting square. Therefore, no energy is created and friction will win. However I developed a magnetic switch that can be applied to weaken the starting point magnetic field by 20%. Therefore rotational energy should be enough to overcome the sticking point. And when sticking point is behind, magnets are again switched on by heating and new revolution is started with full force. As we discussed earlier, it takes about 360 mJ energy to align dipoles and magnetize 1 cm³ neodymium magnet. On the other hand, when magnet is demagnetized 360 mJ heat is released. The alignment process itself is just normal information processing that does not consume energy more than is required to account entropy. We can demonstrate that demagnetization is exothermic reaction if we are heating magnet to curie temperature, because it will take 360 mJ less energy than heating similar non-magnetized body to curie point. Demagnetization does not take energy, but it releases energy. Therefore we can use cooling as rudimentary switch mechanism. Neodymium magnets loses about 20% of magnetism when magnet is cooled from -150°C to -250°C. With other alloys this kind of 'phase transition' could be more prominent that changes the crystal lattice structure so that dipoles get even more misaligned. And when magnet is heated back above transition temperature (-150°C with neodymium magnet), magnet is again magnetized as dipole structure realigns. Hence this alignment and misalignment cycle can be fully reversible. This way we could get also SMOT-derived perpetual motion machine working continuously, if we turn off the magnets when wheel is approaching the sticking point. Therefore, as magnetic field is temporarily weakened with flash-cooling, rotational energy of the wheel would be sufficient for overcoming the sticking point (and friction). This cooling and heating cycle does not bring external energy to the system, because permanent magnets do not store energy. Therefore this cooling and heating idea will not nullify the idea of perpetual motion machine, because we do not use that heat energy for doing the work as a heat engine. This is also where magnetism differs from nitinol spring based heat engine. —Jouni For neodymium magnet behavior at cryogenic temperatures, see: http://www.kjmagnetics.com/blog.asp?p=temperature-and-neodymium-magnets
