[quote=Chew;188789]Yes, it can be done, however, according to the law of conservation of energy
, you may only capable to recover about 10% of the total energy from the battery. Unless you always going downhill, that would be possible to recharge your battery pack from the regenerative process. In a simple word, there must be always an energy lost such as friction, heat, vibration, sound, etc that cannot be recovered.
Interesting point of view, I'm new to this and still running all this new information through my head yet one of the idea's I would like to try is a permanent magnet generator.
these little things range from 200w to 3.5mw, yet they work on a low rpm around 650 - 850 rpm, which is the problem, where to have this unit fitted and how to have it geared down to the low rpm
