Researchers are trying to convert human fecal waste into butanol to power cars of the future.

Butanol is a high-energy fuel similar to gasoline. Using genetically engineered fungus, a scientist at Washington University in St. Louis believes it could one day be produced from one of the world's most plentiful waste products.

He says the key is to find the right genetic modification that will allow the fungi's enzymes to convert the waste into fuel. The scientist cautions the work is still many years away from leaving the lab to the waste treatment facility and onto the road.
