Description: Experiment in wireless power transmission by inventor Nikola Tesla at his Colorado Springs, USA laboratory in December 1900. The light glowing near the bottom is powered by energy transmitted wirelessly from the huge million volt, 300,000 watt magnifying transmitter in his lab nearby. The grounded "receiver" coil shown is tuned to resonance with the transmitter coil, and the lamp is powered by three turns of wire inductively coupled to the coil at bottom. The Century magazine article containing this picture does not say how far away the transmitter is.
