http://www.youtube.com/watch?v=us7YB7eiOeQ first - remember how a windmill works, something makes the propeller spin, which then makes energy. second - if you take a 'windmill' and place it horizontally so the propeller is in the path of the ball in the video, so the ball becomes 'wind', and which then makes energy - isn't that perpetual motion/over-unity/free energy - without breaking any 'laws' of science? i think it is....
now you know how to get energy out of this device - you're welcome!
that video has been removed, but here is another copy
