LAS VEGAS — Ford plans to unveil at this month’s International CES gadget show a solar-powered concept car that offers the same performance as a plug-in hybrid.
The C-MAX Solar Energi Concept car uses a gasoline engine combined with a gizmo that acts like a magnifying glass to concentrate the sun’s rays on the vehicle’s roof-mounted solar panels. The automaker says the vehicle’s estimated combined city-highway mileage is 100 mpg.
The sun-ray concentrator was developed by researchers at the Georgia Institute of Technology and uses what is known as a Fresnel lens, which concentrates light but can be made thinner than a conventional lens. A full day of sunshine is equivalent to a four-hour battery charge.
