This diagram shows the proposed power transfer system for a moving vehicle.
This system transmits electric power thorough a capacitor composed of a steel belt in the tire and a metal plate attached to the road.
The power is supplied in differential mode. Therefore, the electromagnetic field leakage is small. Moreover, the infrastructure can be set up at a lower cost than a coil system.
