...person basement shelter on a design recommended by the Federal Office of Civil and Defense Mobilization (see diagram) could be built by do-it-yourself homeowners for as little as $150, reported the task force. It could be built by a contractor for less than $500. At a small additional cost, perhaps as little as $7 per person, the shelters could be prestocked with enough survival supplies to last through a critical fortnight. Since the intensity of fallout radiation diminishes rapidly, survivors in hard-hit areas could start coming out of their shelters after a fortnight and set about...
...Revelle suspects that the trenches may be part of the mechanism by which continents grow. The first step, he thinks, is for a slow current in the earth's plastic mantle to start flowing horizontally and then curve downward (see diagram). Where it makes the dive, it drags down a strip of the crust, forming a V-bottomed trench which after many millions of years fills with sediment. Eventually the downward current in the mantle stops flowing. Since the mantle rock at its sides is heavier, it moves in, forcing upward the dragged-down crust and the sediments...
...under the rim of the hull, and emerges in jets that point inward, forming a kind of wall. Inside this wall a cushion of air builds up and lifts the Hovercraft off the surface. Forward propulsion is obtained by diverting part of the air flow through horizontal ducts (see diagram...
...Alamos' plasma thermocouple, the solid metals of a bimetallic thermocouple are replaced by a tiny (finch long) rod of uranium suspended inside a vacuum-sealed can that contains liquid cesium. The uranium is enriched with U-235. Around the cesium is a circulating coolant (see diagram). When the device is lowered inside a reactor, the uranium is bombarded by the neutrons generated by the reactor, causing the U-235 to fission and give off intense heat...
...words to the President of the U.S., then gave him the lapel pin worn by 40 finalists in the 18th annual Westinghouse Science Talent Search. Minutes later, unflustered by the company he had just kept, John Seymour Letcher Jr. sat jackknifed in a bus seat, lost in a scientific diagram he was sketching. Next day Letcher, who had won his Washington trip by building a particle accelerator, learned that he had won again. His prize: the $7,500 top award in the Westinghouse contest...
