Algae Converted to Butanol; Fuel Can Be Used In Automobiles:

A team of chemical engineers at the University of Arkansas has developed a method for converting common algae into butanol, a renewable fuel that can be used in existing combustible engines. The green technology benefits from and adds greater value to a process being used now to clean and oxygenate U.S. waterways by removing excess nitrogen and phosphorus from fertilizer in runoff.
“We can make cars go,” said Jamie Hestekin, assistant professor and leader of the project. “Our conversion process is efficient and inexpensive.
