so i have this idea. the thing is i need help with it. the idea is using magnets to make energy. you will need a few very strong magnets and the theory is to take magnets and place them in to oposite rings mount 1 and have the other set on an axle. have this upright so the magnets can rotate freely, then attach a generator to the axle and have the rotating ring turn the genorator. will it work?
