Tesla's wireless lighting tubes. Range of differently shaped vacuum tubes and gas-discharge lamps used by Serb-US physicist and electrical engineer Nikola Tesla (1856-1943) at the 1893 World's Columbian Exposition in Chicago. Tesla demonstrated this and other inventions for the Westinghouse Electric Company, demonstrating how high-frequency and high-voltage electricity could be used wirelessly to cause the tubes to glow with light. | |
