Nikola Tesla was probably one of the biggest inventors and visionaries
of all time. One of his ideas was about transmitting energy without wires, in
1901. In this period, Tesla invented a huge tower, the Wardenclyffe Tower,
built in 1901 and destroyed in 1917, to try transmitting energy across the Atlantic.
His project was never completed due to lack of investments and bad
administration of the building of the tower.
More than a hundred years later, two Russian scientists,
Leonid and Sergey Plekhanov are trying to recreate Tesla’s idea. The new
studies from the Russian scientists states that a tower similar to the one
built by Tesla along with 100.000 km2 solar panels could be enough
to produce and distribute energy for the whole world, solving the problem of
taking power to the most remote places on Earth. As a great area would be
needed the system could be built deserted areas.

The wireless energy works through magnetic coupling. Electromagnetic
radiations are sent when a current flows through a conductor creating an
electrical field. When two alternated electrical fields collide, a voltage and
a current are induced, transmitting the energy from one device to another.
The main problem with the implementation of the
wireless transmission of energy is the noise. Sometimes, the receptor cannot
distinguish between the real energy been transmitted and the interference on
the signal, making the transmission not so efficient as it should be.
The video below shows the idea of the two scientists:
