Ford Solar Power Car

Motor manufacturer Ford unveiled its first solar-power car at the Las Vegas electronics show.

The Ford C-Max Solar Energi Concept Car feature ingegral solar panels on the roof which tracks the Sun's position.

The prototype car is said to be able to travel for 21 miles once fully charged, and a full charge can take 6 to 7 hours.

The vehicle is intended to be parked under a purpose designed concentrator (a bit like a large magnifying glass) that powers it by 100% by renewable energy.
