Wireless Energy

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 Wardenclyffe Tower

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:
