In recent years there has been enormous growth in the use of various wireless technologies. Based on the needs of clients in mobile computing with a minimum amount ever clutter of cables, many service providers, and peripheral manufacturers turned to the wireless standards for creating devices that satisfy the users. All electronic devices need to somehow get energy, which in most cases makes it necessary to use the power cables, but often these cables are rather ugly part of the home environment in general and computers in particular.

Although in recent years in this area appeared notable successes, such as a laptop Dell Latitude Z, which is charged on special base by electromagnetic induction, these technologies still require physical contact. To the delight of those who are fascinated by the idea of a world without wires, Sony announced the development of a new system of energy transfer, which it claims will eventually lead to once and forever abandon the use of power cables.

For the new testing technology manufacturer managed to convey an impressive distance of 50cm to 100V to supply the 22 "LCD-TV. This result was achieved thanks to high-frequency magnetic resonance, for which it was created by the magnetic field by supplying energy in a 40-cm coil of wires. Of course, like any other early prototype, this system has several disadvantages, in particular, limiting the distance over which it operates, as well as 60% efficient, which means the loss of significant amounts of energy during transmission. Sony has not announced how new technology is safe for people, as well as not expressed even a rough estimate of when it will be ready for mass use.
