Guido Franch stole the formula for coal powder to alcohol from his roommate,- a German chemist immigrant from WW2. When the German died, he offered formula for sale to 2 large US companies. They didn't pay the Millions of dollars. . Back at that time period of 1935, the final cost would have been 5 cents per gallon of the final alcohol. Several types of engines were ran on the alcohol. (Motorcycle, tractor, cars, truck, lawn mower, etc.) The bench set up was about nitric and sulfuric acid mixed with fine coal powder , and silver compound used in photography. The heated mixture formed greenish/blue material on upper surface. The material is scraped off and dried into a CATALYST powder. It was photosensitive and must be kept in dark container. One teaspoon of the greenish/blue powder was added to gallon of water. The container has bubbles release, and when settled, can be used as cheap alcohol fuel for engines.
