5 crazy inventions of Nikola Tesla
Nikola Tesla (Serbian Nikola Tesla; July 10, 1856, Smilyan, Austrian Empire, now in Croatia - January 7, 1943, New York, USA) - physicist, engineer, inventor in the field of electrical engineering 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 electricity 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 light bulbs in a process called electrodynamic induction. He dreamed that one day such 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 like Intel and Sony have become interested in using non-radiative power transmission to things like mobile phones, so that we can charge batteries without wires.
Tesla's research in the field of electromagnetism has helped radiologists around the world see the human anatomy without tearing his stomach. However, in the late 1880s, this idea seemed very crazy.
Although the discovery of X-rays is attributed to 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 applying radiation to human flesh.
In the 1930s, Nikola Tesla, according to some assertions, invented a particle beam weapon, which was called the “ray of death”. In theory, the device could generate an intensely directed beam of energy that could be used to destroy enemy planes, 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 would be able to safely and effectively do the work of humans. In 1898, he demonstrated a radio-controlled boat invented by him, 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 an oscillator that shook the building and everything that was near it. The device itself weighed about a kilogram, but the scientist was able to adjust the oscillation time at such a frequency that each small vibration added more energy to the wave bends of the building. With enough small shocks, even the largest building could be shattered into pieces.
Realizing the potential danger of his invention, he smashed the generator with a hammer and asked his employees, in case of which, to state that they were completely unaware of the causes of the earthquake.
