Photos: Solar Power 2006

The Cruise Car, a solar-powered golf cart that can crank up to 22 miles an hour, was among the devices on display this week at the Solar Power 2006 Conference and Expo in San Jose, Calif. It's street legal if used on roads where the speed limit is 35 or under, says Cruise Car, the company that makes the carts. And if you wipe out, it won't burst into flames.
