Scientists at Stanford Are Turning Tesla's Global Wireless Power Grid Into Reality

Using technology originally developed in 2007 at MIT to wirelessly transmit electricity between stationary objects, the research team was able to achieve a power transfer between moving objects based on magnetic resonance coupling. When electricity moves through wires, it creates an oscillating magnetic field, which in turn causes electrons in wire coils nearby to oscillate, thus transferring energy. However, if the oscillating coils are not tuned automatically and continuously as the object moves, the flow of electricity is stopped.

It is a complex process, and until now it has been one of the primary obstacles in transferring energy wirelessly. Stanford's researchers solved this with the use of a commercially available voltage amplifier and feedback resistor, which automatically figures out the right frequency for different distances without the need for human interference.
