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.
