MURFREESBORO, Tenn. (AP) -- A Middle Tennessee State University professor says his coast-to-coast trip using no gasoline had to work around a glitch on the first day.
But Dr. Cliff Ricketts said he's "99 percent sure" the transmission coolant problem his backup driver experienced Saturday was not related to the hydrogen fuel the car is using.
Ricketts and his backup driver are making a trip from Tybee Island, Ga., to Long Beach, Calif., this week.
The cars are being powered by solar energy and hydrogen, which was obtained from water.
