Background: Biofuels
With growing concerns in the global energy market there has been a continual push for the development of renewable energy sources. Specifically, two fuels have dominated the media: biodiesel and ethanol. However, both of these fuels have shortcomings in terms of being a viable fuel source.
Biodiesel is a fuel produced from the vegetable oils of crops that can be used in an engine system very similar to a traditional diesel engine. However, vegetable oils in crops only make a small portion of the biomass of the plants, ultimately producing low yields of fuel per acre of crops. As such, it is more economically advantageous to use these resources for food production.
Ethanol has already seen huge attention to be used in the typical otto cycle engine and in many places is already being blended with gasoline to create a hybrid fuel source. However, running an engine on pure ethanol is beset by several major obstacles. Firstly, ethanol is miscible with water at any concentration, which creates long term storage corrosion issues. In addition, ethanol engines must be designed to expect water vapor unlike their gasoline counterparts. Ethanol also has significantly different thermodynamic properties than gasoline such as a lower energy density and different vapor properties which would reduce the economical advantage of using ethanol as a primary fuels source.
We propose using a different fuels source to eventually replace gasoline, butanol. Butanol is a superior to ethanol as a replacement for petroleum gasoline. With a low vapor pressure, high energy density, and a gasoline-like octane rating, it can be blended into existing gasoline at much higher proportions than ethanol without compromising performance, mileage, cold starting, or volatile organic pollution standards. Blending butanol with gasoline also prevents modifications of the fuel-air ratio and modifications to the fuel system. Butanol also is immiscible with water at concentrations higher than 7%, alleviating storage concerns.

The Project: Plan B
We propose the use of butanol as the leading biofuel for use in internal combustion engines. Specifically we intend to gentically engineer E.coli bacteria to convert biomasses into butanol for use as an energy source. This will be accomplished by introducing the genes responsible for butanol's production in Clostridium acetobutylicum into E.coli. Furthermore, we hope to increase the E.coli's tolerence to solvents such as butanol.
