Tesla holds a highly evacuated, gas-filled tube, powered by one of his high-frequency oscillator units. The one-amp tube operated without any connection to wires (“wireless energy”) over appreciable distances, which could have been greatly extended with more power. Exposure, two seconds with a lamp of 250 candlepower.
