"Most people won't believe you if you tell them that they could get free gas for their car and stop contributing to global warming at the same time. They'd say you're crazy, at least. But, the fact is that it is true--a car can be run on free fuel that is literally thrown away by thousands of businesses all across our country every day. Don't believe it? I have two cars that run on free fuel, and I converted them myself (I'm no mechanic)!"
