5 crazy inventions by Nikola Tesla
Nikola Tesla (Serbian Nikola Tesla, July 10, 1856, Smilyan, Austrian Empire, now in Croatia - January 7, 1943, New York, USA) is a physicist, engineer, inventor in the field of electrical engineering and radio engineering. Born and raised in Austria-Hungary, in the following years he worked mainly in France and the USA. In 1891 he received American citizenship.
Wireless electricity transmission
About 120 years ago, in 1893 at the World Exhibition in Chicago, Tesla demonstrated wireless transmission of electricity by lighting a series of phosphoric lamps in a process called electrodynamic induction. He dreamed that one day this technology will help us transmit electricity over long distances in the atmosphere, providing remote areas with the necessary energy for comfortable living.
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 power wires.
Tesla's research in the field of electromagnetism has helped radiologists around the world see the anatomy of a person without ripping his stomach. However, in the late 1880s this idea seemed very insane.
Although the discovery of x-rays is attributed to the German physicist Wilhelm Roentgen in 1895, it was Tesla 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 statements, invented weapons from a particle beam, which was called the "ray of death". In theory, the device could generate an intensively directed beam of energy that could be used to exterminate enemy planes, the army, and other things. However, the "ray of death" 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 could safely and effectively perform the work of people. In 1898, he demonstrated the radio-controlled boat he invented, which many consider "the birth of robotics". He predicted that soon the world will be filled with smart machines, robots, different sensors and autonomous systems.
Machine that causes an earthquake
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 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 what to declare the complete ignorance of the causes of the earthquake.
