This whole ethanol from corn craze just thoroughly pisses me off. IT's not the best fuel, but that is not the real issue. Corn is a lousy way to make ethanaol - poor energy balance compared to sugar cane, for example. It takes too much energy to make ethanol from corn..it's practically a wash in both an economic and the carbon footrpint sense...if you even buy in to that 'carbon footprint' nonsense being real. But the gummint and tree huggers just love the idea..its the current fad. But the real driver is purely politico-economic; corn prices have soared and subsidized farmers are benefiting hugely. . Thus we are wasting time and money using corn to make ethanol and since corn is the hot ticket for cash crops, there are looming shortages, and resultant price increases, coming at us across the board for all the 'other' ag crops/products that corn is replacing. Been through the peanut capital of the US lately?...all the fields are planted in corn. Between peanuts and soybeans..does anyone know how incredibly many food (and other) products depend on those two little guys?
Oh..and corn is brutally hard on soil, depleting it faster than just about any other crop..requiring crop rotation to legumes, fallow periods, OR massive applications of fertilizer to make up for the losses. Uh oh..that fertilizer is a byproduct of..the petroleum industry. Another oh..over-dosing of fertilizer for corn crops is what 'killed' the Chesapeake Bay..and other estuaries fed by streams that collect farm run off.
And I was a farmer growing up..raised a LOT of corn..and soybeans..and wheat..and barley. Maybe I'm just bitter that this gravy train didn't come around when it would have put money in my pocket.;D
