Westinghouse engineers produce 3,000,000 volts of electricity at the high voltage laboratory in Trafford, Pa. and discharge this high voltage in the form of lightning, along 75 feet of very fine, thread-like wire, arranged in zig-zag form and running from a point well toward the roof of the great room, to the floor. This picture is of the flash discharge.
