Colas's Wattway project adds swaths of solar-powering roadway to Georgia, France, as it broadens solar-energy concept.
Ribbon of solar-paneled bike path is indeed generating some electricity, but not enough to justify the investment.
There's just something appealing about the idea of a solar-powered road. Letting that ugly ribbon through the countryside generate power, interact smartly with cars, bikes and pedestrians and even charging up your electric car. It all just seems magical, doesn't it? Well, yes, which is why there are so many critics of a small (230 feet), $3.7 million solar bike path test space that was just installed in Holland.
