More than a century ago, engineer and inventor Nikola Tesla proposed a global system of wireless transmission of electricity — or wireless power. Now his dream is coming true by the MIT researchers who took solid steps toward more practical wireless charging. They have started a company namsed as "WiTricity" which will be providing wireless charging technology to mobile devices, electric cars and lot of other applications very soon. WiTricity is based on strong coupling between electromagnetic resonant objects to transfer energy wirelessly between them. The WiTricity technology can charge an electric car, with the vehicle parked about a foot above the transmitting pad. At present, WiTricity technology charges devices at around 6 to 12 inches with roughly 95 percent efficiency — 12 watts for mobile devices and up to 6.6 kilowatts for cars. But, with growing research and development, the company is increasing distance, scale, and efficiency. It's also developed repeaters: passive devices that extend the distance of the power transfer. These can be developed into a wide variety of shapes and can be embedded in a carpet to "hop" the power across a room.
