Water Gas Top Rated - Version 2.6.45 I don't expect you to believe in 100% watercars. You see, your belief level has to rise step by step. Free energy is hard to believe until it's actually happening under your own hood. Until you see it in your energy bills. In April 2006 I was skeptic too. I have been skeptic in 2007 that doubling the mileage was possible - until I actually made Water Gas Top Rated happen in my own car.
