Here is an article from several years ago that talks about the future of wireless power transfer, with a few GT quotes sprinkled in for good measure.  A quote about our ECE senior design students:

“Wireless power could enable a whole new class of devices,” says Durgin. Those devices will include sensors on all the mechanics of a home, business or factory; detectors for heat, light and motion; and cameras and controls that we can move and upgrade at our convenience, without ever having to touch the building’s wiring. These controls will include “peel and stick” light switches and thermostats, which are already a common senior design project among Professor Durgin’s students.

For those regular visitors to the site, here is an older talk by lab friend Prof. Matt Reynolds at University of Washington on Wireless Power Transfer.  Prof. Reynolds has been a pioneer in this field for some time, with several past and present start-ups in the area of RFID, wireless power transfer, and RF imaging.
