NICOLAS TESLA investigated how air in a liquefied state absorbed more heat than it needed. In this way, when returning to a gaseous state, it could be used to move a device. However, before finishing the work, his laboratory caught fire and he lost all progress. Some time later, Carl von Linde filed a patent for the same invention.
Tesla used a resonant electrical network and the use of high-frequency alternating current to show that a conductor was used to power an electrical system, without the need to include other elements. The discovery was called transmission of energy through a cable without return.
In his last years, Tesla devoted himself almost entirely to his great dream of transmitting energy aerially, without cables, taking advantage of the conductivity of the upper layers of the atmosphere, the ionosphere, to distribute it freely throughout the planet.
He tried to show that it was possible to send and receive information and energy without using cables. The experiment showed that wireless power transmission was possible
In 2009 a tycoon company like Google now dedicated a doodle to him
in a way to commemorate his birth and everything he did for humanity.
