Roadway for supplying power to vehicles and method of using the same
First Claim
1. A roadway having a surface layer of traffic bearing material, a first lane for traffic moving in a first direction, a second lane for traffic moving in the opposite direction, and means for inductively coupling power to vehicles on the roadway comprisinga power supply,a power source having one section for coupling energy to vehicles moving in the first direction and another section for coupling energy to vehicles moving in the opposite direction, each power source section comprises a source core having a central section in the traffic bearing material and a pair of lateral sections adjacent the surface of the traffic bearing material providing a recess therein, and a source conductor disposed in the recess, andmeans connecting the ends of the source conductor in circuit with the power supply for passing electrical energy through the power source.

Abstract
A roadway having at least one lane for traffic moving in one direction and at least one lane for traffic moving in the opposite direction is provided with power conductors for inductively coupling power to vehicles moving along the roadway. The conductors are embedded in the lanes and extend in the direction of vehicular movement. Power sources are provided along the roadway and the conductors are arranged so as to minimize the lengths thereof which are not directly employed for the inductive coupling of power to vehicles.
