A bacterial strain that turns cellulose to butanol. According to David Mullin: “TU-103 is the only known butanol-producing clostridial strain that can grow and produce butanol in the presence of oxygen, which kills other butanol-producing bacteria. Having to produce butanol in an oxygen-free space increases the costs of production. ?
As a biofuel, butanol is superior to ethanol (commonly produced from corn sugar) because it can readily fuel existing motor vehicles without any modifications to the engine, can be transported through existing fuel pipelines, is less corrosive, and contains more energy than ethanol, which would improve mileage.”
Ergo, we could use all our old newspapers to gain fuel for our cars. Sounds really easy and cheap. But there are other problems with the efficiency and power of this fuel. Because, I'm sure that it matters how much paper you have to “burn” to gain enough fuel to even move your vehicle a few meters.
