I think of some pretty crazy ideas when I'm half asleep. I keep a notebook and pencil by my bed, randomly wake up and write jibberish down. Sometimes great ideas, but most of the time crazy nonsense that I have to wonder what the hell I was thinking, even though they seemed like the greatest ideas in the world at the time. Well anyways, I had this idea while sleeping one night, woke up half awake and wrote it down. Now, I'll be pretty honest here... I don't know just a whole lot about Physics. So, I figure it'd be a good idea to ask some people that do... (recreated in Photoshop exactly as written while half asleep) [PLAIN]http://i.min.us/icbBhq.png [Broken] Right, so. There's my idea. Basically discs with magnets attached like cogs, angled to direct their magnetic force at one another in opposing directions to cause one another to spin on opposite directions, further perpetuating the other's spinning and thus creating perpetual motion. The power created from it would be like an alternator. The kinetic energy/friction created from the magnets would create energy and then it would be stored and whatnot. An alternative concept would be hollow discs with a strong magnetically charged liquid metal running through them, opposite directions in each disc, the magnetic force hopefully causing the other to spin even faster. So yeah, would it work? If not, could you explain why? I imagine I'm not the first one to have the idea of putting opposing magnetic forces to work against one another. So, there must be something I'm missing. I know that the magnetic force in magnets is created by an electrical current passing through them, so maybe that's the hang up? Does it take too much electrical energy to pass through them to maintain a strong magnetic force, so it would be inefficient and use more energy than it creates? My thought was that maybe it would require an initial jolt, but once they got going, they could go with relatively no other help and would be a renewable energy, even if not a true perpetual motion. If anyone could explain, I would greatly appreciate it.
