actually, it was equal energy in/out, it was just magnets guiding a ball with magnetif pulls and momentum. the magnets were likely unmoving. i dont actually know, i have not yet seen this, or anything pertaining to it, first hand, this is second hand information which COULD very well be a load of crap lol


but never the less, i am positively certian that magnetism is all you need to generate electricity, OR that it will replace electricity all together.
