Corn can give us more ethanol, a biofuel, and Fred Michel, a CFAES biosystems engineer (pictured), and Cleveland’s Arisdyne Systems Inc. are working together to get it. Arisdyne’s new “cavitation” technology produces 2-3 percent more ethanol from the same amount of corn, and Michel is helping to test, validate, and refine how it works. Adopting cavitation could boost the U.S. ethanol industry’s annual revenue by an estimated $500-plus million.
