...Today France's million Protestants, about equally divided between Calvinists and Lutherans, are a prestigious minority with a reputation for scrupulous honesty and rigid morals. Their thousand-odd pastors are said to be the worst-paid ministers in Europe; in rural areas they are paid in food and fuel (rural Roman Catholic priests are not much better off). They actively proselytize among atheists and anticlericals, and even claim some success among the Roman Catholic clergy-40 priests have become ministers since the end of the war, according to Pastor Pierre Bourguet, head of France's Reformed Church...
Sometimes inventors draw a bead on one target, score a bull's eye on another. Sacramento's Aerojet-General Corp., prime contractor for the Polaris missile's propellant, found that when the solid fuel was molded, bubbles tended to form, caused trouble in firing. To find the bubbles, the company had to haul the finished rocket motor to a giant X-ray laboratory, spend two to three weeks taking pictures. Aerojet's radiation experts went to work, found they could do the job in hours by slipping in a radioactive cobalt pill, using photon-counters...
...Fuel Cells & Rocket Belts. The next major U.S. inventive breakthrough comparable to the transistor may well be the fuel cell-a cheap, efficient, reliable way of converting fuel to electricity with no moving parts. Some 50 U.S. companies are working on the problem; when it is solved, it will provide a compact, noiseless power source for propulsion, lighting, heating, may even bring back the electric auto. The ancient dream of man, individual flight, perhaps with a scuba-like rocket belt, is under serious development. The U.S. Army has awarded Bell Aero-systems a $60,000 research contract for a rocket...
...European scientists, supplies the answer: midges-and presumably other similar insects-are automatic flying machines. A midge's muscular motor works in much the same way as a piston engine. Once the ignition is turned on. the engine keeps running until the ignition is turned off or the fuel exhausted...
Insect muscles that burn fat are fairly economical, but those that burn carbohydrates such as glycogen are lavish with fuel. Reports Wigglesworth: the carbohydrate-fueled fruit fly, Drosophila, can stay aloft for five hours at a stretch, but it beats its wings 250 times per second, and it burns up 10% of its body weight during an hour's flight-proportionately as much fuel as a 600 m.p.h. jet airliner. Drosophila's cruising speed: 2-3 m.p.h...
