Build and install a low-cost, pollution free, alternative method for running your vehicle (internal combustion) engine on TAP WATER. This efficient system converts ordinary tap water into gaseous Hydrogen and Oxygen, and then burns these vapors in the engine in place of gasoline. This 'minisystem' runs easily from your existing battery and electrical system, and plugs into your carburetor with simple off-the-shelf components. Do-it-yourself plans come complete with diagrams and schematics for easy construction and installation.
