Wireless electricity? It's here!

Wireless electricity - Tesla's dream becoming real!

We're going to transfer power without any kind of wires," says Dr Hall, now Chief Technology Officer at WiTricity, a startup developing wireless "resonance" technology.
"But, we're not actually putting electricity in the air. What we're doing is putting a magnetic field in the air."
It works like this: WiTricity builds 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.
"When you bring a device into that magnetic field, it induces a current in the device, and by that you're able to transfer power," explains Dr Hall.
And like that, the bulb lights up.
