August 17, 1940
This unusual lightning stroke was photographed by Mildred Wollrich, of 175 Sherman Ave., New York, in Steinmetz Hall - General Electric's man-made lightning laboratory at the New York World's Fair.
The six-foot model trylon, made of metal, carries 5,000,000 volts of lightning harmlessly into the ground just as the real, 600-foot trylon conducts natural lightning safely into the ground.
The trylon is, in effect, a vast lightning rod, offering a cone of protection to a large area of the Fair.

Three sections made up the GE pavilion. In Steinetz Hall, there was a ten-million-volt display of electricity over a 30-foot arc. In the House of Magic, there were whirling discs, a floating metal carpet, a solar motor, and a shadow that came and went independent of the person who was casting it.
The Exhibit Hall contained a complete television studio, a model electric appliance store with the full line of GE products and the General Electric X-Ray Corporation's display of an X-Ray machine and a 2,700-year-old mummy.
