Solar Power and or Wind Generation..
I Made my First Wind Generator out of A Junk Yard. A Alternator With a Propeller, Electric Switches from A Car to be able to turn on and off the Power and use it when it is needed and Spin on a Pipe. I Put a Wind guide on the Alternator as well to Direct the Alternator in the proper Wind Direction.
Its Not easy and it doesnt work if there is no wind. Solar power Helps a lot.
