Serbian (US) inventor.
1892 In his laboratory in Colorado, Tesla spent a lot of experiments with high voltage and high- frequency currents. In his lectures and demonstrations in London and Paris Nikola Tesla demonstrated the discharge of his own body and the possibility of gas discharge discharge photographing living organisms in high-frequency currents with the camera. He reproduced the discharge items, corona discharge, and photographed on a photographic plate. His method he called "gas-discharge visualization" of his experiment, he wrote: "The human body has been exposed to a high-frequency electrical generator with a voltage of 2.5 million volts. It was an unforgettable effect. Away from the body long dischargeing bits, like the tentacles of an octopus. From spine beams of light fade. When a man pulls his hands, with the fingertips roaring flames erupt. This effect he called "cold fire» «Cold Fire».
In 1896, the United States, in Colorado Springs, Nikola Tesla put in a physical lab is interesting, but it is very risky experiment. On the generator capacity of 1 million volts it was placed ebony insulator large. He was placed on a metal plate connected to a DC generator. A similar plate was reinforced top. It is also connected to the generator. Nikola Tesla became the lower metal plate, which has been hard rubber pad and was in the field of high voltage. Picture taken at this point showed a bright discharge around the entire body of the scientist. Thus, for the first time in the history of mankind was caught discharge around the person. This phenomenon is called the Tesla effect.Tesla discovered a great therapeutic effect on the action of high-frequency field. When high frequency current is distributed over the skin surface (skin effect), and does not affect internal organs. In 1903, the Wardenclyffe laboratory produces and sells high therapeutic generators medical community across the country. Article 1894 The New York Times, Tesla describes the possible dangers if the voltage and frequency or a too low: In this case, the image of "streamers" cause a tingling sensation as the needle. If the oscillation frequency is quite low, the skin is likely to be broken due to a tremor, blood will be sprayed with great force in a spray or jet is so thin to be visible.
