Wireless electricity – transfer power without any kind of wires

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,”

Don’t worry about getting zapped, the magnetic fields used to transfer energy are “perfectly safe” — in fact, they are the same kind of fields used in Wi-Fi routers.

WiTricity’s plans is to charge smartphones while they are in your pocket as you wander around and electric cars will refuel while sitting on the driveway.

WiTricity has already demonstrated the ability to power laptops, cell-phones, and TVs by attaching resonator coils to batteries — and an electric car refueler is reportedly in the works.
