Popis:

Perhaps the most famous photograph of Serbian-American inventor Nikola Tesla, in his laboratory in Colorado Springs around 1899 supposedly sitting reading next to his giant "magnifying transmitter" high voltage generator while the machine produced huge bolts of electricity. The photo was a PR stunt; a double exposure and Tesla was not in the room while the machine was operating. During 1899-1900 Tesla built this laboratory and researched wireless transmission of electric power. The magnifying transmitter, one of the largest Tesla coils ever built, with input power of 150 kW could produce potentials of around 12 million volts at a frequency of about 150 kHz; capable of producing huge electric sparks, such as the 22 foot bolts shown here. The long arcs shown above were not a feature of the normal operation of the transmitter; for these publicity photos Tesla forced the machine to produce arcs by switching the power rapidly on and off.
