I recently got an email trying to sell me the plans for a Tesla generator, they called it an infinity coil, but I have been wondering for a long time now, why can't a generator be built with permanent magnets, and the attraction and repulsion of the poles. I have seen some on YouTube and they look like they should work, however if they did, then everyone would have one. I have a better than average handle on physics and understand that friction and other forces are at play. Can anyone who is a scientist, and uses a straight razor, explain whether any such contraption can work? In plain English. This particular one says it's using technology from Tesla, and, as we know, he was able to draw electricity from the atmosphere when no one else has been able, at least from what I have read about his time out west. It has been reported that he successfully transmitted current as far as ten miles. I don't know, I wasn't there. I know we have them, so a few answers from some smart people, please.
