     It's sad to see people diving head-first into the idea of using corn to 
produce bio-diesel.  Corn requires more fertilizer per acre than most of not 
all other cereal grains, and the process of extracting nitrogen from the 
atmosphere to make it is very energy intensive.  The process was invented in 
Germany prior to WWI, and after the war the munitions factories were converted 
to fertilizer factories.  If not for that process, world population would have 
leveled off at around 2 billion due to the limits of non-fertilizer food 
production.
