The world needs a new source of energy, an unspillable source.

how to make a wind generator?

I have an old welding machine(which is basically a generator) that can make up to 250 amps. Can and how do I make it into a wind turbine and how do I hook it up to an U.S. standard house hold curcuit beaker. What other equipement do I need to possibly cut down my energy cost(i.e. car batteries, or larger capacity batteries) and is it worth my cost to build a frame to mount it to my roof or build a tower for it, to reap the benefits of wind generated power from scrape material.
