Can’t say this bums me out.  Corn ethanol is a bridge solution, and I think we’ve passed the bridge. From the NYT:

Barely a year after Congress enacted an energy law meant to foster a huge national enterprise capable of converting plants and agricultural wastes into automotive fuel, the goals lawmakers set for the ethanol industry are in serious jeopardy.

As recently as last summer, plants that make ethanol from corn were sprouting across the Midwest. But now, with motorists driving less in the economic downturn, the industry is burdened with excess capacity, and plants are shutting down virtually every week.
