This was the first decoration he received for his scientific work., What was his great success at the Chicago World's Fair in 1893?  - avilions were lit with the help of twelve of Tesla’s two-phase generators, each producing 1,000 horsepower at a frequency of 60 Hz., What was put into operation on the Niagara River in 1896? - On the night between November 15 and 16, the first large alternating current hydroelectric plant was put into operation on the Niagara River. The first kilowatts were transmitted from Niagara to the city of Buffalo, about forty kilometers away. Of the twelve patents used in construction of this plant, nine belonged to Nikola Tesla., What did he established in 1897? - The basis of radio technology (Tesla built a new and bigger radio station and transmitted radio signals over a distance of more than forty kilometers. He submitted two key patent applications for radio. “System of Transmission of Electrical Energy”, no. 645,576, describes a system of four resonant circuits tuned to the same frequency and a system of transmitting and receiving antennas. Patent no. 649,621, “Apparatus for Transmission of Electrical Energy”, describes the radio apparatus.), What did he demonstrate in Madison Square Gardens in 1898?  - At the first exhibition on electrical apparatus in Madison Square Gardens, he demonstrated the famous experiment in which he controlled the movement of a model boat remotely using radio waves. He submitted a patent application under the title “Method of and Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles”, no. 613,809 on July 1. It was granted by the US Patent Office on November 8 that year. Aware of the great importance of this patent, he protected it in eleven countries., What did he experiment in Colorado Springs in 1899? - He went to Colorado Springs on May 18 intending, as he put it, “to construct a high-frequency generator of great power, to perfect a method for the individualization and mutual isolation of the transmitted energy and to determine the laws governing the transmission of power through the earth and the atmosphere”. From June 1, 1899, to January 7, 1900, his collected research notes contain various recorded values and calculations, many diagrams, remarks or comments on the daily experiments and the use of new configurations of instruments, apparatus and the connections between them., What did he build in Long Island 1901-1902? - Construction of the laboratory and tower for his World System of Wireless Transmission began in 1901, designed by the renowned American architect Stanford White. It was completed in 1902, although the tower, as originally envisaged, was never finished. According to Tesla’s plan, signals from the transmission tower would be sent wirelessly through the Earth, which is a conducting body, and received anywhere on Earth., What did he describe in the ,,Art of transmitting electrical energy through the natural mediums"? - In it he described the concept of “stationary waves”, which he found to have wavelengths of from 25 to 70 kilometers. From his own research he concluded that waves of this kind could propagate through the earth in all directions. Tesla’s intention was to confirm the idea of the resonance of the planet. He expected that these resonances would be 6, 18 and 30 Hz., What did he build in 1907? - the first working model od a bladeless turbine (In the field of mechanical engineering, Tesla discovered the original principle of the propulsion of fluids which he applied to pumps, turbines, compressors and fans.

It was awarded to Tesla on December 13, 1916, for his discoveries in the field of polyphase and high-frequency currents. It was formally presented at a ceremony at the American Institute of Electrical Engineers on May 18, 1917), What did he publish in 1919? - He published his famous autobiography “My Inventions” in six instalments in the well-known popular scientific magazine Electrical Experimenter. The magazine was founded and edited by his friend and great admirer, the inventor Hugo Gernsback (1884-1967)., What was his final patent? - In his 72nd year he was granted his final patent for “Apparatus for Aerial Transportation”. He was the first to imagine a flying machine with vertical take-off and landing, a combination of helicopter and fixed-wing which would be powered by his turbines., What did he publish in 1934? - In the New York Times he published an obituary for the murdered King Aleksandar I Karadordevic of Yugoslavia., What projects did he propose (1934-1941)? - Tesla used the newly-coined term “telegeodynamics” to describe a technology for transmitting energy mechanically through the earth. He offered his mechanical oscillators and transmission and receiving apparatus to renowned American companies such as Texas, Westinghouse and Buffalo. These devices could be used to transmit signals and messages through the earth in navigation and industry and for the production of various revolutionary effects., What contract did Tesla sign in 1935? - On April 20, 1935, Tesla signed a contract with the Soviet trade representatives in New York, the Armtorg Trading Corporation. It dealt with protecting the Soviet Union from enemy aggression by building an impenetrable wall created by a new weapon. In this contract he undertook to, within a deadline of four months, submit a detailed project with drawings of installations which could generate a potential of 50 million volts, fire a beam of concentrated particles at a distance of at least 150 kilometers, with a maximum velocity of at least 50 kilometers a second, and produce devastating effects at the target., When did Tesla die? - 7th January in1943 (Tesla died in his sleep, in his apartment on the 33rd floor of the New Yorker Hotel, where he had spent the last nine years of his life.
