University of Minnesota researchers say they have produced hydrogen from ethanol in a prototype reactor small and efficient enough to heat small homes and power cars. Current methods of producing hydrogen from ethanol require large refineries and lots of fossil fuels.
The reactor is a 2-foot apparatus of tubes and wires that produces hydrogen from corn-based ethanol. A fuel cell, which acts like a battery, then generates power. The research appeared in the Dec. 13 issue of Science.
