Summary edit
| Description |
English: Speculative drawing of wireless power transmitters envisioned by Serbian American inventor Nikola Tesla powering a fuelless aircraft, illustrating Tesla interview in 1934 magazine. During 1891-1906 Tesla had experimented with short-range wireless power transmission, and claimed to have a method of transmitting power long distances through the atmosphere using large elevated high voltage terminals. He envisioned a World Wireless System consisting of a worldwide network of dome-shaped antennas similar to those in the drawing, which would transmit both power and information over areas of hundreds of miles to power homes, factories, and vehicles. In the magazine interview Tesla is quoted: "We are on the threshold of a gigantic revolution, based on the commercialization of the wireless transmission of power... Motion pictures will be flashed across limitless spaces... The same energy will drive airplanes and dirigibles from one central base..." Although there is no evidence Tesla ever actually transmitted power long distances, and his attempt to build a prototype transmitter 1902-1906, the Wardenclyffe Tower, in Long Island, New York, lost funding and failed, his vision has inspired people ever since. Caption: "Nikola Tesla, electrical wizard, foresees the day when airplanes will be operated by radio-transmitted power supplied by ground stations, as shown” |
