LABORATORY SERIES. No.02. Nikola Tesla’s Colorado Springs Laboratory. Publicity photograph of Tesla reading next to the ‘Magnifying Transmitter.’ The Colorado Springs lab was built in 1899 at Pikes Peak after Tesla concluded it was possible to transmit electrical power without wires at high altitudes. The lab was reinforced with large metal grounding plates and a roof that rolled back to prevent it from catching fire. Photo: Dickenson V. Alley of Century Magazine in 1899 / Wikipedia.
