TESLA a.s. is a Czech manufacturer and supplier of special radio communication and security electrical engineering for military and commercial use. The name was originally used by a state-owned conglomerate that was the monopoly producer of electronic appliances and components in the former Socialist Republic of Czechoslovakia.
Tesla's design for Wardenclyffe grew out of his experiments beginning in the early 1890s. His primary goal in these experiments was to develop a new wireless power transmission system. Tesla discarded the idea of using the newly discovered Hertzian waves (radio waves), detected in 1888 by German physicist Heinrich Rudolf Hertz. Tesla doubted ...
The Wardenclyffe Power Plant prototype, intended by Nikola Tesla to be a "World Wireless" telecommunications facility.. The World Wireless System was a turn of the 20th century proposed telecommunications and electrical power delivery system designed by inventor Nikola Tesla based on his theories of using Earth and its atmosphere as electrical conductors.
In 1898 Nikola Tesla developed a radio/coherer based remote-controlled boat, with a form of secure communication [93] [94] between transmitter and receiver, [95] which he demonstrated in 1898. Tesla called his invention a "teleautomaton" and he hoped to sell it as a guided naval torpedo. [96]
The Great Radio Controversy is the second studio album by American hard rock band Tesla, released in 1989.The album's sound has been described as "glam metal to play inside the cab of a tractor-blusey denim and downright wholesome".
A second type of spark gap that had a similar quenching effect [15] was the "rotary gap", invented by Tesla in 1896 [92] [93] and applied to radio transmitters by Reginald Fessenden and others. [ 17 ] : p.359–362 [ 79 ] It consisted of multiple electrodes equally spaced around a disk rotor spun at high speed by a motor, which created sparks ...
Tesla coil circuits were used commercially in spark-gap radio transmitters for wireless telegraphy until the 1920s, [1] [4] and in medical equipment such as electrotherapy and violet ray devices. Today, their main usage is for entertainment and educational displays, although small coils are still used as leak detectors for high-vacuum systems.
The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
