5 crazy inventions of Nikola Tesla
Nikola Tesla (Serb. Nikola Tesla; July 10, 1856, Smiljan, Austrian Empire, now in Croatia - January 7, 1943, New York, USA) - physicist, engineer, inventor in the field of electrical and radio engineering. Born and raised in Austria-Hungary, in subsequent years he mainly worked in France and the USA. In 1891 he received American citizenship.
Wireless power transmission
About 120 years ago, in 1893 at the World's Fair in Chicago, Tesla demonstrated wireless transmission of electricity by lighting a series of phosphor bulbs in a process called electrodynamic induction. He dreamed that one day such a technology would help us transmit electricity over long distances in the atmosphere, providing remote areas with the necessary energy for a comfortable stay.
Now, after more than a century, large companies such as Intel and Sony have become interested in applying non-radiative energy transfer to things like mobile phones so that we can charge batteries without power wires.
Tesla’s research in electromagnetism has helped radiologists all over the world see the human anatomy without tearing open his stomach. However, in the late 1880s, this idea seemed quite crazy.
Although the discovery of X-rays is attributed to the German physicist Wilhelm Roentgen in 1895, it was Tesla who, in his experiments with this technology eight years before Roentgen, drew attention to some of the dangers of using radiation for human flesh.
In the 1930s, Nikola Tesla, according to some claims, invented weapons from a particle beam, which was called the "death ray". In theory, a device could generate an intensely directed beam of energy that could be used to destroy enemy aircraft, the army, and other things. However, the "death ray" was never released by Tesla, although he tried to sell it to various military units.
Tesla imagined that in the future a whole race of robots will be able to safely and efficiently perform the work of people. In 1898, he demonstrated a radio-controlled boat he had invented, which many consider to be the "birth of robotics." He predicted that the world would soon be filled with smart machines, robots, various sensors and autonomous systems.
In the same year, 1898, Tesla announced that he had developed a vibration generator that shook the building and everything that was next to it. The device itself weighed about a kilogram, but the scientist was able to adjust the oscillation time at such a frequency that every small vibration added more energy to the wave bends of the building. With enough small shocks, even the largest building could be shattered.
Realizing the potential danger of his invention, he broke the generator with a hammer and asked his employees, in which case, to declare complete ignorance of the causes of the earthquake.
