Lucas123 writes "Ford plans to demonstrate its first solar-powered hybrid vehicle at CES next week. The Ford CMAX Solar Energi Concept car will have 1.5 square meters of solar photovoltaic cells on its roof to generate power to charge its battery. By themselves, the PV solar panels generate only 300W of power — not enough to charge the vehicle's battery in one day. Ford, however, said the car will be coupled with a carport that has solar concentrating lens atop it. The magnifying lens, called a Fresnel lens, will concentrate about 10 times the solar energy so the vehicle can be recharged in a single day — the same speed with which a standard hybrid charges using a plug."
(Of course, some charge faster than others.)
