It's hard to believe wireless power is even possible, but it most certainly is, and Sony has just filed a patent showing how it's getting closer to perfecting it. Sony's figured out how to precisely locate a device so its wireless power loss will still be in the practical range.
Sony's even figured out a way to daisychain devices, having one gadget sending power to another, as long as all are within the most efficient range. I think the most useful application of this technology will be used for charging electric cars, letting you jump out of the car and run into your house without having to deal with plugs and wires.
