Several months ago i built a windmill out of a car alternator. My dream was to be able to collect so much electricity that the electric company would be sending ME a check every month.
My dreams were crushed.
A simple way of explaining it was that the wind would spin the alternator, charging up the car batteries, which would go to the DC to AC converter, which would plug into the house. Apparently plugging car batteries directly into an outlet in your house is not good... who knew?
So the windmill had been sitting in my basement in a pile labeled "crushed dreams" Other things were there like a hang-glider made out of a bed sheet and the human powered hydrofoil. I still haven't given up on the hydrofoil...it's too amazingly awesome:

Here's all the pieces before i put it up in the back yard.
Here it is all put together in the basement.
