This seems like a pretty big breakthrough.

Using patented microorganisms and transformative bioreactor designs, Coskata ethanol is produced via a unique three-step conversion process that turns virtually any carbon-based feedstock—including biomass, municipal solid waste, and a variety of agricultural waste—into ethanol, making production a possibility in almost any geography. The technology is ethanol-specific and enzyme independent, requiring no additional chemicals or pre-treatments.

Simply put, the Coskata process can produce ethanol almost anywhere in the world, using practically any renewable source, including feedstock, garbage, old tires and plant waste. And it can do so for less than a dollar per gallon.

I wonder what the equivalent cost per barrel of oil that represents? It seems like it would make sense to convert jet engines at that price, if you can.
