How about the transmission of electricity at a distance? Wires to the dustbin of time?

How about the transmission of electricity at a distance? Wires to the dustbin of time? More recently, we have used the phones with "prishnurovannymi" to shells tubes, only 17 years ago could be no question about the wireless internet connection. It seems now 1,111,114. We are witnessing a loss of wired technologies have on one front - in the transmission of electrical energy. [/b]

In a press release, Massachusetts Institute of Technology reported that a team of scientists led by Marin Solyachichem able to demonstrate the process of power 60-watt bulb in the air from a power source located at a distance of more than two meters.

According to the accounts of the scientist, the idea of wireless devices supplying electric power came to him in the night when he was the sixth time in a month was awakened by a sound of its own mobile phone, urgently requires the inclusion in the socket. Now we can hope that in the near future, our phones, PDAs, laptops and start their own players to fill the battery with electric power - without the intervention of the owners and wires.

Compared with lasers (which require fine tuning and not safe) and electromagnetic waves (the cost of almost all the energy in empty space), a new way to distribute electricity in the air is applicable in practical terms.

  The essence of the device lies in the fact that the transmitting and receiving copper coils tuned to the same resonant frequency. The first coil is circulating around nonradiating magnetic field, oscillating at a frequency of several megahertz. No other object, except the receiving coil is not immune from the field, because it does not vary with the same frequency. Thus, a new method of transmission of electrical energy is safe for humans, animals and electronics.

It is worth noting that the idea of transfer of electricity at a distance is not new - in the early 20 th century, Nikola Tesla proposed the theory of the possibility of transmission not only of radio waves, but electric power over long distances. He even started construction in New York laboratory Wardenclyffe - it was a tower about 60 meters with a steel shaft, lowered by 40 meters into the ground. The tower is crowned with a metal dome with a diameter of about 20 meters. However, after some time sponsors have stopped funding the project, and the experiment was not completed.

Today, scientists have only to increase the efficiency of the tested device (which is currently 40%) and reduce its size - then we will be able to enjoy the power of our little electronic helpers without wires and sockets. And in the future, this could result in a fully-independent steady supply of industrial robots and huge savings on infrastructure transmission of electrical energy to consumers.
