CHARLES H FRAZER ELECTROLYZER – Patent:1,262,034 – April 9 – 1918 – Designed to increase the efficiency of an internal combustion Engine. This patent shows just how long guys have been thinking about Hydrogen and how it can be used in the engine. Nothing new indeed and yet we still do not have it accepted for every day use. Still the realm of the back yard tinkerer. I do believe we are seeing some light at the end of the tunnel, but that remains to be seen. NEVER GIVE UP.
