World's First Electrified Road For Charging Vehicles Opens In Sweden (theguardian.com)

A 1.2-mile stretch of road with electric rails has been installed in Stockholm, Sweden, allowing electric vehicles to charge up their batteries as they drive across it. "The technology behind the electrification of the road linking Stockholm Arlanda airport to a logistics site outside the capital city aims to solve the thorny problems of keeping electric vehicles charged, and the manufacture of their batteries affordable," reports The Guardian. From the report: Energy is transferred from two tracks of rail in the road via a movable arm attached to the bottom of a vehicle. The design is not dissimilar to that of a Scalextric track, although should the vehicle overtake, the arm is automatically disconnected. The electrified road is divided into 50m sections, with an individual section powered only when a vehicle is above it. When a vehicle stops, the current is disconnected. The system is able to calculate the vehicle's energy consumption, which enables electricity costs to be debited per vehicle and user. The "dynamic charging" -- as opposed to the use of roadside charging posts -- means the vehicle's batteries can be smaller, along with their manufacturing costs. A former diesel-fuelled truck owned by the logistics firm, PostNord, is the first to use the road.

  1. 1.2 miles of road? by mark_reh · · Score: 3, Insightful

    Driving 1.2 miles might take 5 minutes, maximum. How much power can they possibly transfer to the vehicle battery in that time?

      Also, the very first fax machine was a completely useless product, since there was nobody to send faxes to or receive faxes from. I don't know why they even bothered to manufacture it.
