Nikola Tesla was an inventor who obtained around 300 patents [1] ... U.S. patent 433,700 - Alternating-Current Electro-Magnetic Motor - 1890 August 5 ...
Nikola Tesla (/ ˈ n ɪ k ə l ə ˈ t ɛ s l ə /; [1] Serbian Cyrillic: Никола Тесла, [nǐkola têsla]; 10 July 1856 – 7 January 1943) was a Serbian-American [2] [3] engineer, futurist, and inventor. He is known for his contributions to the design of the modern alternating current (AC) electricity supply system. [4]
The two metal sheets are connected to a Tesla coil oscillator, which applies high-voltage radio frequency alternating current. An oscillating electric field between the sheets ionizes the low-pressure gas in the two long Geissler tubes in his hands, causing them to glow in a manner similar to neon tubes .
The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...
An alternating current of any frequency is forced away from the wire's center, toward its outer surface. This is because an alternating current (which is the result of the acceleration of electric charge) creates electromagnetic waves (a phenomenon known as electromagnetic radiation).
"Egg of Columbus" demonstration at the 1893 Columbian Exposition. Tesla's Egg of Columbus was a device exhibited in the Westinghouse Electric display at the 1893 Chicago World's Columbian Exposition to explain the rotating magnetic field that drove the new alternating current induction motors designed by inventor Nikola Tesla by using that magnetic field to spin a copper egg on end.

According to the story, in 1931, Tesla modified a Pierce-Arrow car in Buffalo, New York by removing the gasoline engine and replacing it with a brushless AC electric motor. The motor was purportedly powered by a "cosmic energy power receiver" contained in a box measuring 25 inches by 10 inches by 6 inches, which contained 12 radio vacuum tubes ...
