"Cold Light?"

Lamplighters went out of fashion when electricity came in. Last week members of the American Physical Society, meeting in Chicago, heard Professor Charles Tobias Knipp describe a new kind of electric light which may bring lamplighters back, set them to lighting lamps with electricity once every six months. Professor Knipp had made a flask of pyrex glass of 22-litre capacity, with a stem two metres long and 70 millimetres in diameter. He pumped out the air and moisture, filled the flask with nitrogen gas, sealed it. Around the stem he wrapped a wire, touched the wire to a 25,000-volt high-frequency generator. There was a flash, then the bulb began to glow with a bright yellow light. It continued to glow for 35 minutes after the shock had been administered. Four months later, Professor Knipp repeated the procedure. For no reason that he could see the bulb remained bright for no minutes. The third time it glowed 187 minutes, fourth time 165 minutes.

Said Professor Knipp: "I am continuing these tests. It seems like electrodeless cold light. If I may freely speculate, some day these afterglow lamps may be made that would burn for six months, at no cost of electricity."
