Initially ethanol production made a lot of sense to both reduce our dependance on foreign oil AND subsidise corn producers by creating another market for under-priced corn. Both proposes have been met sucessfully.
Currently, corn is no longer under-valued and is a now high priced input for producing ethanol. The ethanol plant by Buffalo Lake, MN was recently awarded to it's lenders (in forclosure?).
I my opinion, ethanol production will eventually need to shift from consuming high priced corn to using lower cost inputs: corn stover, straw, crops that can be grown and harvested on erosion-subsidised ground, downed trees, leaves, yard waste, moldy hay, road-side grasses, used cardboard, etc. The production process might have to change with the seasons to match the inputs available. Managing a plant using a wide variety of low quality inputs will be much more difficult than using one consistent high-quality input like corn.
So far little progress has been made to use other inputs. That may doom ethanol production in the future.

When dealing with thinner metals like sheet tin, a long bolt and
