ARTIFICIAL LIGHTNING NOW WITHOUT DEAFENING NOISE
Complete lightning phenomena can now be produced in comfort in the laboratory. One artificial 100,000-ampere lightning stroke produced in Westinghouse’s Sharon, Pa., testing laboratories caused spectators to hold their ears to shut out the thunderous noise, as shown on the front cover of this week’s Science News Letter.
Engineers have developed a muffler, however, that shuts out the noise and allows observers to stand close to the lightning-current generator while it is operating.
