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.
