Omaha, NE - Thirteen teams from around the world are racing to go green, and they're doing it without using gasoline. They are driving in the North American Solar Challenge from Dallas to Alberta, Canada. Nick Such is racing the University of Kentucky team's car. He says driving it could be worse considering there's no air-conditioning, "When you're moving along it's not too bad. It's when you are just sitting in the sun that it gets pretty hot." But it's those hot rays that fuel one of his goals, to use mother nature's resources for energy.
