hybrid vehicles

MURFREESBORO, Tenn. (WMOT)   --  A team of researchers from Middle Tennessee State University are attempting to drive cross-country this week on less than 10 gallons of gasoline.

MTSU Professor Cliff Ricketts, six students, and a couple of alumni volunteers were on schedule to pass through Oklahoma City at noon Tuesday on their way to Long Beach California.  They’re driving experimental hybrid vehicles that run on a variety of energy sources, including solar, hydrogen gas, ethanol and gasoline.
