I don't understand the incentive of doing this, let alone the cost to develop it! The term wireless is supposed to give you a reasonable range of operation that allows you to move your device.
So if you use a cable to charge a phone, you can actually place the phone anywhere in the radius of the cable length. With this wireless charging option, you actually have to place the phone right on top of the circle... allowing you device to only spin around that exact spot. If you move the device any more than that, it will not charge.
What's the point? I don't get it!"
