The inventor of this thing is the father of the alternating current Nikola Tesla, the fruits of which we use every day, including anything in the AC outlet. If you saw at the store were glass balls with digits inside, this relative of the installation in the photo – generator, Tesla high frequency and high voltage.
Despite the intimidating appearance of the discharge (although it is hard to believe), but they are completely harmless to humans. The fact that the currents of such high frequencies are on the surface of the skin without causing any harm to humans. At the exhibition, where Nikola Tesla demonstrated the first transformer high frequency he was connected to the device and from his hands the hall was hitting spectacular branching of lightning. Even now it looks fantastic, and at the end of the 19th century it produced a shock, Tesla was considered almost a witch.
Interesting point in the physics of this process is that at the moment there is no physical theory that explains the effect of Tesla transformer. More precisely, such a theory was the Tesla, but it broke with classical physics refers to physics alternative that recognizes the physical aether as a real medium of transmission of electromagnetic waves. Nikola Tesla conducted and other amazing experiments, such as electric power transmission on one wire and even non-metallic conductor.
A native of Croatia, Nikola Tesla is the most mysterious scientist of the 20th century. Giving humanity the alternator he was still life left in the “underground” and earned the reputation of “the mad scientist”. Unlike Edison, who was more talented businessman than a scientist (by the way, Tesla for some time worked for Edison, but then they quarreled), Nikola Tesla was a man for whom science and knowledge stood in front of commercial benefit. The imagination of this genius increasingly took him away from the beaten scientific track.
