They have limited seating (usually one, sometimes two people), they have very little cargo capacity, and they can only be driven during the day. They do, however, offer an excellent opportunity to develop future technologies that can be applied to practical applications.

The cars are powered by the sun, but the race itself is powered by the organization and dedication of college students. It started with the Stanford Solar Car Project, a loose collection of 40 or so students who have so far built two solar cars with a little faculty advice and a lot of hard work. Graduate student Dave Caditz spearheaded the idea of a race that would zig-zag across California and inspire the public's interest in alternative-powered vehicles.
Solar car races were led across the first-day finish line by the Western Washington University's Viking XX, a sleek car under a slanted array of solar cells like a roof of shiny blue tile. The Viking, which reached Stanford with an elapsed driving time of 4 hours, 27 minutes, placed fifth internationally in the World Solar Challenge in Australia last November.
