Homemade VAWT Wind Turbine?
I am making a VAWT out of scrap for my senior project. I am going to use it to power a well that uses 240 KWH per year and runs at 230 V. It will be about 15ft in the air. My question lies in converting the mechanical energy to power. Should i use a car alternator, a dc generator, or a permanent magnet generator? Also, I am planing on connecting the generator right up to some car batteries and those up to the well; can I do that and if so, how should I wire it and how many 12v car batteries do i need.
Specs: Air scoops will extend out about 5 ft in each direction. Average wind speed is about 7.5 mph.
Also, how should i mount it on a 15ft telephone pole (once i have planted the pole in the ground)

If you use an automotive alternator and automotive batteries, (you'll probalby need about 4),
all the electrical engineering is done for you and all you need are the right size pulleys
for your average wind speed.
(With that kind of cross section, that pole had better be very securely stayed.
You are going to see 60+ MPH gusts at least once/year just about anywhere.)
