Corn has joined the list of popular alternatives to fossil fuels. Its high heat value, ease of handling, and ready availability in some sections of the United States have growers looking for information on cost, handling, and equipment suppliers. Although burning corn isn't for everyone, a grower who is near a good supply may find that it can reduce heating costs significantly. A 200,000 BTU/hr corn furnace will provide the heat for a 25-foot x 96-foot double poly greenhouse in all except the northern tier of U.S. states and will burn about half a bushel of corn per hour.
