Solar-Powered Cars Still a Ways Ahead
Toyota's third-generation Prius, due at dealerships this spring, will have an optional solar panel on its roof. The panel will power a ventilation system that can cool the car without help from the engine, Toyota says.
But it's a long way from the 2010 Prius to a solar-powered car, experts told CNN. Most agree that there just isn't enough space on a production car to get full power from solar panels.
"Being able to power a car entirely with solar is a pretty far-reaching goal," said Tony Markel, a senior engineer at the federal government's National Renewable Energy Lab in Golden, Colorado.
