Reference Entry
Solar cars don't have gas tanks. Instead, they have panels of solar cells--small wafer-like units that change light into electrical energy. Engineers test their latest models by racing them. The 2,300-mile American Solar Challenge, from Chicago to Southern California, is the longest race.Engineers admit that solar cars won't replace gas-powered cars any time soon. The big challenge is to design a battery that can store enough energy to keep the car running when the sun isn't shining.
