1. A system comprising:
a convertor configured to receive power from a general electricity network and to produce power of at least one phase;
a primary inductive array for installation in a road configured to operate as a primary winding to receive and inductively transfer power from the convertor, the primary inductive array comprising a series of sections, each section comprising at least a number of primary coils corresponding to the number of phases of the convertor,
wherein the primary inductive array is in electromagnetic communication with a receiver array adapted for installation beneath a vehicle configured to operate as a secondary winding, including at least one receiver section comprising at least a number of receiver coils corresponding to the number of phases, each receiver coil being configured to receive power from a corresponding primary coil installed in a road, while the vehicle moves on the road above the primary coil, wherein said receiver array is configured to provide excess power back to the number of primary coils, said excess power being providable to other vehicles by the primary inductive array; and
a communications unit configured to receive a signal from a vehicle communications coil adapted for location in the vehicle in front of the receiver array in the driving direction of the vehicle, the communications coil configured to send a signal to a communications unit via a corresponding one of the primary coils,
wherein said signal is induced to the coils of the primary inductive array and to operate corresponding primary inductive array sections to provide power to a receiver attached to the vehicle.
