Lowering the friction | Charging Up Nissan's Electric Car Without Wires : TreeHugger
By taking out of some of the consumer friction, Nissan's engineers have made it easier for consumers to park their cars and have their batteries recharged without the hassle of plugging them in. The recharging is completed through the principal of electromagnetic induction, "when two coils (one on the ground and one under the car) come into proximity, a charge can be transferred from a power supply to the battery. It takes a few seconds for the primary and secondary coils to recognize each other, but once they do, the system could charge the small electric vehicle (above) in three hours." Treehugger.
The implications of this could be huge, imagine for a second that each parking spot or parking garage had these electric induction coils under the pavement, so that when you paid to park your car it would automatically recharge your batteries. A point of differentiation for carparks maybe? Just stick a windmill on the roof and away you go, green parking.
