Wireless Everything?

If the internet and phone services are wireless, why in the world do we still have wired electricity? It's not actually putting electricity in the air. What we're doing is putting a magnetic field in the air. It works like this: WiTricity build a "Source Resonator" -- a coil of electrical wire that generates a magnetic field when power is attached. If another coil is brought close, an electrical charge can be generated in it. No wires required. In the house of the future, wire-free energy transfer could be as easy as wireless internet. If all goes to WiTricity's plans, smartphones will charge in your pocket as you wander around, televisions will flicker with no wires attached, and electric cars will refuel while sitting on the driveway. WiTricity have already demonstrated their ability to power laptops, cell-phones, and TVs by attaching resonator coils to batteries -- and an electric car refueller is reportedly in the works. Talk about exciting.
