Description
English: Nikola Tesla demonstrating wireless transmission of power and high frequency energy at Columbia College, New York, in 1891. The two metal sheets were connected to his Tesla coil oscillator, which applied a high voltage oscillating at radio frequency. The electric field ionized the gas in the long, partially evacuated Geissler tubes he is holding (similar to modern neon lights), causing them to emit light without wires.
