On Wednesday Spain unveiled a telephone box in which users can both make a phone call and recharge the battery of an electric car.

The cabin in a Madrid suburb close to the headquarters of the Spanish telecommunications giant Telefonica has the appearance of a normal telephone box but is also equipped with electric sockets that can be used for recharging. The dual-purpose phone cabin, the first of its kind, has been developed by Telefonica and electricity company Endesa, a statement said.

Spain’s socialist government wants to see up to 250,000 electric cars on the country’s roads by 2014.
