Called CleanFlex Power System, the unusual process was developed as a way to burn more ethanol in the U.S. Currently, CleanFlex is being tested in a stationary John Deere power system, and Dickey says it's working well. In addition to the diesel fuel (which could also be biodiesel), the ethanol used in CleanFlex is cut to 60 percent with water (called EM60). You can hear Dickey talk about the system over at Domestic Fuel.
