Electrical engineers at Stanford built a cardiac device that uses a combination of inductive and radiative transmission of power, at about 1.7 billion cycles per second, to its coiled receiving antenna.
The A4WP's solution is a "non-radiative magnetic resonance-based wireless power transfer ecosystem" -- in short, it allows your phone, tablet or other A4WP-certified gadget (such as light bulbs, as demonstrated above) to charge from a small distance.
