There was an article on page B1 of the 12 December 2005 issue of The
Wall Street Journal, "Demand Pops for Furnaces That Burn Corn". Basic
point is that corn costs less than ordinary fuels (which has to be a
consequence of farm subsidies, one would think). They also tell of
discouraging someone living in an apartment on the 33rd floor of a
Manhattan apartment building from getting a corn furnace, if for no
other reason that cheap corn isn't exactly common outside of the corn
belt.
