Artificial Lightning

10,000,000 VOLTS OF MAN-MADE LIGHTNING

Like some scene from Dante's Inferno are these photographs from General Electric's high-voltage laboratory in Pittsfield, Mass.

They were taken at the moment of discharge of ten million volts of electricity--the highest voltage ever poured forth as man-made lightning.

Such a voltage will project an arc of 60 feet if space allows. In one of the accompanying pictures the arc is 30 feet in length, while in the other it has been shortened to 15 feet in order to change its form.

Coincident with the arcing-over there occurs a tremendous crash, which resounds throughout the steel-lined laboratory.
