Biomass Fuel: Kilowatts From Corn Cobs

Small communities could realize an economic gain from recycling corn cobs into biomass fuel for electrical generation.

This pile of corn cobs towers above the man standing in the lower right-hand corner of the photo, yet it represents only half a year's production of waste material at just one of Iowa's seed corn companies. Because the cobs are naturally porous, they don't gain or retain much moisture in outdoor storage (even when unprotected) and thus make an excellent feedstock for a biomass fuel gasifier.
