Mike Brown’s experiment:
1975 Chevy Suburban Dual Fuel Unit runs on gasoline and alcohol

These photos show a working model of a dual fuel unit installed in a 1975 Chevy Suburban.  The driver could convert from gasoline to alcohol in two seconds from controls on the dashboard.

Mike Brown built this unit in 1979 because he had walked past a supermarket checkout stand and saw a copy of the now-defunct National Tattler with an article titled, “Suppressed Inventions and How They Cost Americans Billions.”  Mike bought a copy, took it home, read it, and enrolled in a Power Mechanics class at Berea College, Kentucky.  The article featured a photo of the Fish carburetor.

Then Mike took more college courses including machine shop practice and chemistry.  As a result of the courses and the experiment, Mike wrote Brown’s Alcohol Motor Fuel Cookbook, a how-to book describing how to turn grain (primarily corn) into alcohol and modify carburetors to run on it.  Mother Earth News sold over 80,000 copies of the book.
