Even if it worked perpetual motion is useless, it would have to create more energy than it used and in a large amount. before it becomes useful. But it doesn't work anyway.
In this video they claim the efficiency is around 3:1, which would be useful.
Don't get me wrong, I think this is BS and nothing will come of it, but I was just wondering what effect licencing would have and if it would be possible for something like this to be used by anyone, or are we still going to end up paying for energy one way or another.
