Corn-fueled stoves causing a real heat wave

Corn is the new king when it comes to heating stoves.
It appears that every manufacturer of corn-fueled stoves in the United States and Canada is facing a backlog of orders because of the huge demand. Both manufacturers and dealers seem to have been caught by surprise by the wave of consumer interest.
Why all the sudden hullabaloo? Simple – nothing costs less to burn at this point than corn, which sells for about $2 per bushel. According to figures provided by Even Temp, maker of the St. Croix line of stoves, the cost per therm for 100,000 British thermal units is 42 cents. The same per therm cost for natural gas is $1.40 and $2.60 for propane (LP). Wood is 64 cents per therm.
And Dennis Buffington, a professor of engineering at Penn State University, provided these figures in a recent Wall Street Journal story about corn stoves: For 1 million BTUs of heat, it takes $16.47 in natural gas, $33.80 in propane and a mere $8.75 for corn.
