What did Nikola Tesla invent?

Answer 1

You mean besides the Tesla Coil?

Nikola Tesla invented the Alternating current, hydroelectric power , fluorescent light, laser beam, wireless communications, wireless transmission of electrical energy, remote control, robotics, Tesla's turbines and vertical takeoff aircraft, X-ray tubes of his own design, vacuum tube which emitted light to be used in photography, a bladeless steam turbine based on a spiral flow principle, a pump design to operate at extremely high temperature, basic system of radio, an instrument to receive radio waves the radio, Alternating Current Motors and Transformers.
Tesla is often described as the most important scientist and inventor of the modern age. He is best known for many revolutionary contributions and inventions in the field of electricity and magnetism in the late 19th and early 20th centuries. Tesla's patents and theoretical work formed the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution systems and the AC motor, with which he helped usher in the Second Industrial Revolution.

After his demonstration of wireless communication (radio) in 1894 and after being the victor in the "War of Currents" ( in the late 1880s, George Westinghouse and Thomas Edison became adversaries due to Edison's promotion of direct current (DC) for electric power distribution over alternating current (AC) advocated by Westinghouse and Nikola Tesla.), he was widely respected as one of the greatest electrical engineers who worked in America. Much of his early work pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. But due to his eccentric personality and his seemingly unbelievable and sometimes bizarre claims about possible scientific and technological developments, Tesla was ultimately ostracized and regarded as a mad scientist. Never having put much focus on his finances, Tesla died impoverished at the age of 86.

Aside from his work on electromagnetism and electromechanical engineering, Tesla has contributed in varying degrees to the establishment of robotics, remote control, radar and computer science, and to the expansion of ballistics, nuclear physics, and theoretical physics.

Many interpret the 1943 Supreme Court of the United States decision as crediting Tesla as being the inventor of the radio.

Nikola Tesla, at the 1893 World's Columbian Exposition in Chicago, demonstrated a device he constructed known as the "Egg of Columbus." It was used to demonstrate and explain the principles of the rotating magnetic field model and the induction motor. Tesla's Egg of Columbus performed the feat of Columbus with a copper egg in a rotating magnetic field. The egg spins on its major axis, standing on end due to gyroscopic action.

Tesla's device (two-phased induction motor) used a toroidal (doughnut shaped) iron core stator on which four coils were wound. The device was powered by a two-phase alternating current source (such as a variable speed alternator) to create the rotating magnetic field. The device operated on 25 to 300 hertz frequency. The ideal operating frequency was described as being between 35 to 40 hertz. Reproductions of the device are displayed at the Nikola Tesla Museum in Belgrade, the Technical Museum in Zagreb and in the Ann Arbor Hands-On Museum.

Nikola Tesla (Serbian: Никола Тесла; 10 July 1856 - 7 January 1943) was an inventor, mechanical engineer, and electrical engineer. He was an important contributor to the birth of commercial electricity, and is best known for his many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries. Tesla's patents and theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor. This work helped usher in the Second Industrial Revolution.

Born an ethnic Serb in the village of Smiljan (now part of Gospić), in the Croatian Military Frontier[1] of the Austrian Empire (modern-day Croatia). Tesla was a subject of the Austrian Empire by birth and later became an American citizen.[2] Because of his 1894 demonstration of wireless communication through radio and as the eventual victor in the "War of Currents", he was widely respected as one of the greatest electrical engineers who worked in America.[3] He pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. In the United States during this time, Tesla's fame rivaled that of any other inventor or scientist in history or popular culture.[4] Tesla demonstrated wireless energy transfer to power electronic devices as early as 1893, and aspired to intercontinental wireless transmission of industrial power in his unfinished Wardenclyffe Tower project.

Because of his eccentric personality and his seemingly unbelievable and sometimes bizarre claims about possible scientific and technological developments, Tesla was ultimately ostracized and regarded as a mad scientist by many late in his life.[5] Tesla never put much focus on his finances and died with little funds at the age of 86, alone in the two room hotel suite in which he lived, in New York City.[6]

The International System of Units unit measuring magnetic field B (also referred to as the magnetic flux density and magnetic induction), the tesla, was named in his honor (at the Conférence Générale des Poids et Mesures, Paris, 1960).

In addition to his work on electromagnetism and electromechanical engineering, Tesla contributed in varying degrees to the establishment of robotics, remote control, radar, and computer science, and to the expansion of ballistics, nuclear physics, and theoretical physics.

Answer 2

Nikola Tesla invented many things in his lifetime, but some of his best achievements are Radio, Alternating Current (AC), AC Induction Motor (which is used in many electrical items today), Robotics, Man Made electricity, and the Tesla Coil.
