I am very interested in trying to build my own small wind generator, I seen that you basically need a alternator, blades to build the fan, cabling and a battery. So could you use a car alternator and also how many 12V batterys would you need?
I think that was a little rude, judging by what you posted you seem to be a all around d*ck!
But thanks to the others who replied, you info was very helpful. thanks again.
You may have better success with an alternator with the field coils replaced with permanent magnets and the regulator removed. This will maximize the voltage output and allow you to regulate the voltage at the battery bank. The less electronics and other items to break up the tower the more reliable the system will be.
You should use deep cycle batteries, not automotive starting batteries. The number of batteries will depend upon the voltage your system operates, power capacity of the generator, and size of inverters. Do not go overboard with too many batteries or the generator will never be able to fully charge them.
There is someone near me who is building the blades with PVC pipe. He uses it to turn a permanent magnet DC motor to act as the generator. I'll try to find his web page later.
I'm hoping to get back to my wind generator project shortly. It's been tied up in municipal bylaws and idiotic permits…
