The world's first solar highway has been opened in France, in the not-very-sunny village of Tourouvre au Perche in Normandy. The roadway is just one kilometre (0.6mi) long, but that still works out at 2,800 square metres of photovoltaic cells—enough, hopefully, to power the village's street lights.
The road was built by Colas, a large Anglo-French construction company. Colas has apparently been working on its own solar road tech, called Wattway, for at least five years. Wattway has been tested in car parks, but this is the first time it has been used on an active road. There will now be a two-year test period, to see if Wattway can withstand the rigour of being pounded by thousands of cars and trucks per day, and whether it can actually provide a useful amount of electricity.
