An electrified road in Sweden that is the first in the world to charge vehicles as they drive along is showing promise and could potentially help cut the high cost of electric cars. The government-funded project, named eRoadArlanda and costing about $5.82 million, uses a modified electric truck that moves cargo from Stockholm's Arlanda airport to Postnord's nearby logistics hub to test the technology. A electrified rail embedded in the tarmac of the 2 km road charges the truck automatically as it travels above it. A movable arm attached to the truck detects the rail's location in the road, and charging stops when the vehicle is overtaking or coming to a halt.
