Bla, bla, thermodynamics, bla, bla, study some physics, bla, bla. OK, lets study some physics we learned at elementary school. How do you make a permanent magnet? You keep stroking a metal rod with an existing permanent magnet. Remember that one? You put energy into the system, the kinetic energy of stroking it. So why is it fundamentally ridiculous that you could attempt to get the energy back out, while at the same time, depleting the strength of the magnet? Now lets imagine the problem. The problem may be that when two magnets attract they move towards each other spontaneously until they don't. You've done it many times in your life. Where did that energy come from? It came from a marginal depletion of the magnetism in the magnet. The opposite, rather, of stroking it to put the magnetism in. Now lets imagine harnessing that energy through rotational torque. The problem seems rather obvious: You want to have a fixed magnet and a rotating magnet sitting directly on top of it. The rotating magnet will of course rotate until that poles are oppositely aligned then it will stop. How do you make it continue to rotate? Well obviously you need a way to switch the polarity of the rotating magnet every half turn. So, the concept seems to be, that you have a permanent magnet whose polarity you can switch every half turn, using either no energy to do so, or less energy than the torque generated upon rotation. Then, the thing will rotate not perpetually, but until the magnetism runs down. I don't have any idea how they would switch the polarity of one of the permanent magnets every half turn, and I don't know whether this is what they are doing, but I think its not fundamentally ridiculous in terms of the laws of thermodynamics, etc. What is an issue is rigid thinking. - Shyaku
