Gerald Rowley keeps his dreams in his garage. There ... he stores an aging Mazda 626 sedan [specially outfitted with a] one-gallon steel box in the trunk connected to fuel lines leading to a gasoline vaporizing device under the hood. The steel box holds one gallon of regular unleaded gasoline. The device beneath the hood is called the VFS, Vaporizing Fuel System. I came here to drive Rowley's VFS-equipped car. For years, I had spurned the invitations of homespun inventors worldwide to travel to distant points to witness first-hand machines that could deliver 100 miles per gallon or 200 miles per gallon. The claims sounded too incredible to believe -- ridiculous, in fact. If such devices really worked, really did what their inventors said they did, why would they still be sitting on shelves in anonymous workshops -- ignored by the driving public and all of the vehicle manufacturers who serve them? What automobile manufacturer in its right mind, especially with rising concerns about future oil availability and with gasoline prices escalating worldwide, would not jump at the opportunity to acquire a device that delivered 100 miles per gallon? Rowley's patented device is nothing new. It's just the latest iteration of an idea already developed by others -- the notion that you could get more miles per gallon out of a traditional gasoline engine if you pre-heated the fuel to about 350 degrees Fahrenheit, thus turning it into a vapor before it enters the combustion chamber. Vaporized fuel, when properly mixed with air, burns more efficiently, saves fuel and emits fewer tailpipe pollutants than traditional fuel-air mixtures in which gasoline is sprayed into a combustion chamber in tiny droplets and then mixed with air before burning. All car companies know this.
