...French Pyrenees, a great, flat mirror, nearly 40 ft. on a side, stares all day at the sun, turning automatically. Facing it is a parabolic mirror almost as big, into which the flat mirror throws reflected sunlight. The combination acts as a gigantic burning glass which can melt 130 Ibs. of iron in an hour. The fierce spot of concentrated sunlight can bore holes through aluminum oxide (the material used to line electric furnaces...
...burning glass is not a new idea. The pioneer French chemist Lavoisier built one almost 200 years ago and succeeded in melting iron with the sun's rays. The one at Mont Louis, by far the biggest ever built, has reached a temperature of 2,500° C. (4,500° F.). Electric furnaces can also reach high temperatures, but experiments conducted in them are complicated by carbon from the electrodes. The sun's concentrated rays are pure heat; they can melt or vaporize a substance without contaminating...
Bullying and aggressive, she is Shaw's symbol of entrenched wealth, and perhaps his embodiment of a thesis that unless wealth keeps on snowballing, it will melt away. Challenged to live on a pittance, she goes to work in a slum and in no time is richer than ever. In one of his most effective passages, Shaw has her defend her resistance to all charitable appeals on the theory that it is the first step that counts, that to part with a farthing may open the door to losing a fortune. Shaw, who loved money itself almost as much...
...Staff will be wanting five years hence. Northrop's job is to make them want what he designs. Right now, Northrop is worrying about the "thermal barrier"- the speeds where air friction will disintegrate metal planes. He is experimenting with fuselages made of glass fiber, which will not melt at those speeds. Looking further ahead to the days of pilotless planes, Northrop already has about 14% of his work force on guided missiles, expects a production contract soon. Against rainy days, Northrop Aircraft has no more plans for scooters; instead it is making pilotless target planes, on the assumption...
Someone else was trying to solve the Iranian problem last week. Her name was Madame Sadika Garagozlou. She was a slim ash blonde with full-blown lips and eyes that would melt the heart of an Italian galley pirate, if not of a British diplomat. In Rome last week, she left behind a trail of perfume, but what she had to sell was more pungent: Iranian...
