Volvo's Battery-Less Semi Truck Concept "Electric Road's"

Volvo's engineers are recently thinking a bit differently than the people at Tesla in the form of EV's.  Above, Richard Sebestyen posses for Volvo's new battery-less commercial semi truck that pulls power directly from the road.  

Now I know all of the questions that are arising in your heads, but remember, this is Just a Concept!  Many more answers will be coming, so just hold off on your criticism because Siemens is trying to do overhead cables for powering public roads like city transit trains are use to, and for public roads, the criticism needs to be about that horrific idea.  I figured Siemens would be better than that.  

When ideas and concepts come out that could change the world, don't hate.  Instead, think of the possibilities, the endless possibilities!

The two power rails/lines run along the road's entire length. One is a positive pole, and the other is used to return the current. The lines are sectioned so that live current is only delivered to a collector mounted at the rear of, or under, the truck if an appropriate signal is detected. As an additional safety measure, the current flows only when the vehicle is moving at speeds greater than 60 km/h (37 mph).

"The vehicle is equipped with a radio emitter, which the road segments can sense," explains Volvo's Per-Martin Johnansson. "If an electric vehicle passes a road segment with a proper encrypted signal, then the road will energize the segments that sense the vehicle."

The truck being used as a test bed for the project is a standard Volvo FH12 tractor sporting a diesel engine. There's no electric motor installed at the moment. When the collector comes into contact with the power lines, 750 V of direct current is delivered and routed to a water-cooled heating element, that has a similar power requirement to an electrically-driven truck. The collector has been designed to track the power rails, even when the vehicle is not directly over the middle of the contact lines.

The present phase of the project, which is supported by the Swedish Energy Agency, is set to come to a close soon, but Volvo is already discussing the next logical step. This will see the installation of an electric motor in the truck to determine how it fares on the test track. Johansson confirmed that other project members are working on various electricity delivery methods, including induction charging.
