Engineered Bacteria Excrete Propane Fuel

Propane Tank Jessie Eastland aka Robert DeMeo Propane, the gas that fuels your barbecue (and perhaps one day your car), may soon have a new, renewable source. Researchers in Finland and England developed a genetic process that puts E. coli bacteria to work producing the flammable compound.
