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. The goal is for the solar car to use exactly the amount of energy that is have coming in from the sun.

Racers made a pit stop in Bellevue Wednesday. The teams rest and inspect every inch of the car and wipe down solar panels with precision. So how does it work? Veteran racer Andrew Rutgers says the cells on top of the car are connected together through wires. The power is then collected and comes through a large wire. It then goes into devices called power tractors. The energy is converted and sent to the battery pack and motor.

The teams race not only each other, but the weather. With a sunny day, cars can speed to 40 mph. Cloud cover will only allow them to reach 20 mph. These teams press on across the country, ready to try and solve the problem of finding alternative fuel, "I don't think solar cars are going to be the answer, but I think all of the different parts of this can be applied to the future of transportation."
