Hot off the heels of a solar plane making the final leg of its journey across the United States, the students behind the Stanford Solar Car Project began the final preparations for their own solar-powered, cross-country journey. They will compete against 46 other teams in the Great Solar Challenge, a 2,000-mile race in the Australian Outback.

Luminos, the official name of the group's solar car, is unlike other electric and solar cars available on the market today. Its sole purpose is to participate in the Great Solar Challenge.
