1. ### Designing a three phase permenent magnet generator

I am designing a three phase permenent magnet generator , and have a question. as a magnet pair passes over a coil , inducing a voltage, that voltage is most dependent on ? 1) the angular velocity ( thats a given) 2) the pole strength 3) flux density 4) energy product. 5) thickness of...
2. ### Flow battery

Do a google on " flow battery " this woman from Austrailia did some recent work with them ,really interesting stuff.. in Japan they use them to supply Grid Power from a windfarm ..
