The last one actually requires natural gas to be pumped through the cells, it isn't a magnet.
I do like the idea of using magnets... I tried the bicycle wheel with just magnets alone back in 2002, but could not keep it running and gave up on it..
No it wasn't precise and I didn't use physics or calculus, and that was part of the problem... besides, I did not have much time each evening to mess with it
I was also at the time studying hydraulics to use a few water tanks and small water wheels to charge a battery much like the bedini wheel did with magnets. (larger tank above draining thru small drain holes [jetted] under which water paddle wheels are placed, spinning the generators to charge the battery, to run small pumps to replace the water back in the large tank, and hopefully have a small excess of power)
But I never got it off paper and into production......ahhhh life, it just gets in the way don't it?
