  2. Tesla coil - Wikipedia

    en.wikipedia.org/wiki/Tesla_coil

    A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. [1] It is used to produce high-voltage, low-current, high-frequency alternating-current electricity. [2] [3] Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.

    Nikola Tesla patented the Tesla coil circuit on April 25, 1891. [4] [5] and first publicly demonstrated it May 20, 1891 in his lecture "Experiments with Alternate Currents of Very High Frequency and Their Application to Methods of Artificial Illumination" before the American Institute of Electrical Engineers at Columbia College, New York.

    The facility has several huge Tesla coils on the facility grounds, some of which range over 20 stories in height. Combined these create what the Soviets nicknamed a "lightning machine." Combined these create what the Soviets nicknamed a "lightning machine."

    Also, Tesla spent a tenth of his time researching miscellaneous subjects. The authors notes J. R. Wait's comment on Tesla activity, "From an historical standpoint, it is significant that the genius Nikola Tesla envisaged a world wide communication system using a huge spark gap transmitter located in Colorado Springs in 1899.

  6. Streamer discharge - Wikipedia

    en.wikipedia.org/wiki/Streamer_discharge

    Streamer discharges into the air from the high voltage terminal of a large Tesla coil. The streamers form at the end of a pointed rod projecting from the terminal. The high electric field at the pointed end causes the air to ionize there. Video clip of streamers from a Tesla coil.

  7. Henry Leroy Transtrom - Wikipedia

    Henry Leroy Transtrom (1885–1951) was an American inventor and showman who worked with high voltage electricity.His book, Electricity at High Pressures and Frequencies, [1] (1913) is still used as a guide for constructing homemade Tesla coils.

  8. Bifilar coil - Wikipedia

    en.wikipedia.org/wiki/Bifilar_coil

    German physicist Wilhelm Eduard Weber made use of the bifilar coil in his 1848 electrodynamometer. [3] Large examples were used in inventor Daniel McFarland Cook's 1871 "Electro-Magnetic Battery" [4] and Nikola Tesla's high frequency power experiments at the end of the 1800s. [5]

  9. Tesla Experimental Station - Wikipedia

    en.wikipedia.org/wiki/Tesla_Experimental_Station

    The Tesla Experimental Station [1] was a laboratory in Colorado Springs, Colorado, USA built in 1899 by inventor Nikola Tesla and for his study of the use of high-voltage, high-frequency electricity in wireless power transmission. Tesla used it for only one year, until 1900, and it was torn down in 1904 to pay his outstanding debts.
