chk out 'picoturbine'. the principle is ingenious : generation is based on tangential velocity rather than angular velocity. it can easily be scaled up. speaker magnets will do the trick (scrap car speakers, for ex), and some varnished wire. savonius are slow, but simple and cheap to build. the secret is to build a 'cage' for the savonius so you don't have a long shaft in cantilever, but rather a 'beam supported at both ends'. you can hang everything out in the breeze too, magnets wont mind. well designed savonius' are self starting, that's why they are used on top of darrieux turbines to help start them. if a savonius is 'split' into two 90Ħoffset halves, it will work at slower wind velocities. the picoturbine alternator design obviates start-up drag. also, the lighter the 'vanes' the more efficient the savonius. the cage construction allows for large, yet very light, 'vanes'. a 'boost/buck' charger will increase energy storage potential of a savonius. the idea is you come in with 2 to 24 volts, and come out at a steady 13.8. savonius can be 'stayed' easily, there's no 'weathervaning'. for simplicity, easy maintenance, ease of construction, and reliability, nothing beats a savonius with a 'picoturbine' style alternator. but if you gear a regular generator to it, it sucks. a savonius could also be used to process biodiesel...(:-D) cheers, dick. ------------------------ Yahoo!
