Quadrotor UAVs used to wirelessly deliver power

Not only are quadrotors fun, they're useful for applications like surveillance and are even showing promise in building construction. Here's a practical use we hadn't thought of though - remote wireless charging. The folks from NIMBUS lab at the University of Nebraska-Lincoln are developing a quadrotor equipped with a system that uses strongly-coupled magnetic resonances to transmit power from its batteries to the receiving device without ever needing to make physical contact. The roboticists see this as a solution for powering devices that are otherwise inaccessible to conventional electrical sources.
