Consequently, a direct current power station was required at two mile intervals. Direct current flows continuously in one direction; alternating current changes direction 50 or 60 times per second and can be stepped up to vary high voltage levels, minimizing power loss across great distances. The future belongs to alternating current. Nikola Tesla developed polyphase alternating current system of generators, motors and transformers and held 40 basic U.S. George Westinghouse bought, determined to supply America with the Tesla system. Edison did not want to lose his DC empire, and a bitter war ensued. This was the war of the currents between AC and DC. Tesla -Westinghouse ultimately emerged the victor because AC was a superior technology. It was a war won for the progress of both America and the world. In February 1882, Tesla discovered the rotating magnetic field, a fundamental principle in physics and the basis of nearly all devices that use alternating current. Tesla brilliantly adapted the principle of rotating magnetic field for the construction of alternating current induction motor and the polyphase system for the generation, transmission, distribution and use of electrical power. Tesla astonished the world by demonstrating.
World Columbian Exposition in Chicago in 1893. Alternating current became standard power in the 20th Century. This accomplishment changed the world. He designed the first hydroelectric powerplant in Niagara Falls in 1895, which was the final victory of alternating current. The achievement was covered widely in the world press, and Tesla was praised as a hero world wide. King Nikola of Montenegro conferred upon him the Order of Danilo. Tesla was a pioneer in many fields. The Tesla coil, which he invented in 1891, is widely used today in radio and television sets and other electronic equipment. That year also marked the date of Tesla's United States citizenship. His alternating current induction motor is considered one of the ten greatest discoveries of all time. Among his discoveries are the fluorescent light , laser beam, wireless communications, wireless transmission of electrical energy, remote control, robotics, Tesla鈥檚 turbines and vertical take off aircraft. Tesla is the father of the radio and the modern electrical transmissions systems. He registered over 700 patents worldwide. His vision included exploration of solar energy and the power of the sea.
He foresaw interplanetary communications and satellites. The Electrical Review in 1896 published X-rays of a man, made by Tesla, with X-ray tubes of his own design. They appeared at the same time as when Roentgen announced his discovery of X-rays. Tesla never attempted to proclaim priority. Roentgen congratulated Tesla on his sophisticated X-ray pictures, and Tesla even wrote Roentgen's name on one of his films. The breadth of his inventions is demonstrated by his patents for a bladeless steam turbine based on a spiral flow principle. Tesla also patented a pump design to operate at extremely high temperature. Nikola Tesla patented the basic system of radio in 1896. His published schematic diagrams describing all the basic elements of the radio transmitter which was later used by Marconi. In 1896 Tesla constructed an instrument to receive radio waves. He experimented with this device and transmitted radio waves from his laboratory on South 5th Avenue. Gerlach Hotel at 27th Street in Manhattan.
The device had a magnet which gave off intense magnetic fields up to 20,000 lines per centimeter. The radio device clearly establishes his piority in the discovery of radio. The shipboard quench-spark transmitter produced by the Lowenstein Radio Company and licensed under Nikola Tesla Company patents, was installed on the U.S. In December 1901, Marconi established wireless communication between Britain and the Newfoundland, Canada, earning him the Nobel prize in 1909. But much of Marconi's work was not original. In 1864, James Maxwell theorized electromagnetic waves. In 1887, Heinrich Hertz proved Maxwell's theories. Later, Sir Oliver Logde extended the Hertz prototype system. The Brandley coherer increased the distance messages could be transmitted. The coherer was perfected by Marconi. However, the heart of radio transmission is based upon four tuned circuits for transmitting and receiving. It is Tesla's original concept demonstrated in his famous lecture at the Franklin Institute in Philadelphia in 1893. The four circuits, used in two pairs, are still a fundamental part of all radio and television equipment. The United States Supreme Court, in 1943 held Marconi's most important patent invalid, recognizing Tesla's more significant contribution as the inventor of radio technology.
