...program was leading only to prohibitively expensive means of obtaining competitive electrical energy, and last week it announced a shift in emphasis: funds for the Brookhaven liquid-fuel project and similar ones elsewhere have been largely diverted to AEC's Oak Ridge laboratory for development of a thermal breeder reactor that will make uranium 233 from thorium, the first natural raw material other than uranium to be used as a producer of peaceful atomic energy...
...cause "eclipse blindness"-lesions of the retina, so called because they have most often happened to people who watch eclipses of the sun without protecting their eyes. Rabbits were chosen as the test animals. AEC scientists found that an explosion the size and height of Teak delivers its thermal energy in less time than a rabbit (or a man) can blink. Said the report grimly: "Retinal burns were produced in the rabbits at distances up to 300 nautical miles." This tended to support earlier Army research indicating that an atomic fireball bursting over a battlefield at night could produce mass...
...offices. The elevators, stairs and toilets were grouped in a central service core at the axis of the prongs. To cut down glare from floor-to-ceiling windows, Breuer incorporated a variety of sunshade devices (horizontal sun-louvers, vertical slabs, extended brackets holding panes of thermal glass) that varied according to the various sun conditions and enriched the façades with glittering patterns...
...years but is still far from perfect. Heavy seas, hammering the hull of a destroyer, can override the sonar-transmitted sounds of distant submarine screws or reduction gears. The sun heats the thin layer of air over smooth water, and this in turn can bend radar waves. Sometimes a thermal layer, 100 to 300 feet deep, distorts sound-and a knowledgeable sub skipper plays this layer like a shield. He can confound enemy sonar by hiding in the clacking wake of a destroyer, or by backing the submarine through his own wake to lose himself in his own echo...
...Falls. The Argonne reactor is a natural-circulation boiling water reactor: it produces steam simply and directly in its core instead of in a separate heat exchanger leading to the turbogenerator, and has an air-cooled condenser that drastically cuts down the total water needed. Full capacity: 3,000 thermal kw. -enough to light 260 average homes or (if used as radiator steam) to heat...
