#Sewage

It’s not often publicly remarked upon, but the emphasis on biofuel capacity in the United States has a bit of an international political component to it. American farms exported well over 100,000 metric tons of corn and oilseed in 2010. Some major portion of that production was sent to oil-rich areas which are short on food. The E85 boondoggle can be viewed as a simple declaration to those nations: we can burn your food in our cars, but you can’t eat your oil.

America’s pretty good at producing another item besides food, however, and if early research is any indication, it could be used to run a significant portion of the nation’s car and truck fleet.
