Harry, standard QM does not comment on plausibility of magnetic motors. And for classical mechanics refrigerator magnets and spiral galaxies are exactly as impossible constructions as this magnetic motor. It is just that in classical mechanics work is ill-defined, because classical mechanics just assumes gravity and rigidity of bodies without explaining them.
Mark, I agree, that this should be demonstrated as a proof of concept for perpetual motion machine. There is nothing new however, because the underlying mechanics is the same as with refrigerator magnet. As the video was very good and it clearly explained the the principles behind the perpetual motion, this should be very easy to replicate, because 3D-printers and neodymium magnets are popular toys for geeks. And certainly I do not think that this could be practical power source, because permanent magnets are far too weak for commercial scale power production. Solar, wind and nuclear are way cheeper free energy sources and they will last billions of years. It is however curious that windmills also utilises neodymium magnets to generate electricity, so perhaps we already are using this same magnetic phenomena, without actually understanding that actually wind-power is acting against classical mechanics! ―Jouni On Sep 5, 2012, at 12:00 AM, Harry Veeder <hveeder...@gmail.com> wrote: > According to standard physics, it is impossible to design a magnetic > motor that won't get stuck after a few turns.
