Summary

[edit]
Description
English: Serbian-American inventor Nikola Tesla in his laboratory in Colorado Springs supposedly sitting in front of his giant high voltage "magnifying transmitter" generator while the machine produces huge sparks. The photo was a double exposure by Century Magazine photographer Dickenson V. Alley. First the machine's discharges were photographed in the darkened room, then the photographic plate was exposed again with the machine off and Tesla sitting in the chair. In his Colorado Springs Notes Tesla admitted the photo was a double exposure:
Of course, the discharge was not playing when the experimenter was photographed, as might be imagined!

and this is confirmed by Tesla biographers Carl Willis and Marc Seifer.

Tesla built the lab and between 1899 and 1900 researched wireless power transmission there. The magnifying transmitter, one of the largest Tesla coils ever built, with input power of 300 kW could produce potential of around 12 million volts at a frequency of about 150 kHz, creating 130 ft. (41 m) "lightning bolts".
