Right now there are many wirelessly powered devices available. Cell phone and tablets can charge simply by placing them on a USB powered pad or a specially equipped flat surface.

Beyond that, there are devices that harvest energy directly from the environment. "The most widely used energy harvesting devices rely on solar, thermal, RF, and piezoelectric sources of energy." These devices are deployed as remote sensors and controls. The key is that they are very low power and they communicate over an RF connection.

As we are able to implement more functions at these low energy levels we will have less need for copper wiring interconnections. Lighting controls come to mind right away, why route that current down the wall to a switch box and back when it only needs to be used at the light itself?

I would be surprised if there are not at least a few attics in the US being lit by RF energy coupling from an antenna to a 4 foot fluorescent tube. The antenna only needs to be tuned to a nearby radio station. The FCC has rules against this, but you can appreciate detectability is low and the simplicity makes this a tempting implementation for at least a few individuals. Again, the key is to have a reasonably efficient low power application.

Induction heating is one high power application in common use in factories and homes. It is commonly used for welding and heat treatment in manufacturing. In our home it shows up in inductive cooktops. In this application the coupling is efficient because it is at close range.

As far as large scale energy transfer over long distances that will have to wait a bit. Like solar, the first implementations will only be cost and energy efficient for off-grid applications. Until the economics and safety are addressed this is a niche solution, relegated to your induction stove top.
