WiTricity startup presents current and energy-efficient distance transmission technology. WiTricity – a startup developing wireless resonance transmission technology electricity.
Here’s how it works: WiTricity created the “resonator oscillator” – a coil of electrical wire voltage generates an alternating magnetic field. If you make in this field is another coil, an electric current is induced in it. No wires are required and the “light comes on.”
I must admit that the idea of this development is by no means new – Nikola Tesla was almost engaged in similar experiments. a century ago. The problem was that efficiency this method of energy transfer was low, but the head of the project WiTricity Dr. Katy Hall and colleagues managed to solve this problem thanks to the use of modern technology.

The magnetic fields used to transfer energy are completely safe – they are of the same kind that are involved in Wi-Fi routers. And in the house of the future, energy transfer without wiring can be as simple as wireless access The Internet.
WiTricity has already demonstrated the capabilities of its technology in relation to the power of laptops, mobile phones and TVs by connecting the resonator coils to their batteries – and, rumored to be an electric vehicle charger.
WiTricity also works with a medical company manufacturing implantable pacemakers. This technology opens the door to the creation of mobile electronic devices, which is still restrained only by a limited battery life.
The challenge now is to increase the distance that can carry out efficient energy transfer. This distance is connected with coil size, and WiTricity has high expectations for its new creation: AA batteries without wires.
