...worst jobs in the plant. The men worked amid screeching ear-splitting noise where there was no air-conditioning and poor ventilation and where the temperature reached 120 degrees. The lighting was dim, the floors were oily, and a thick blue mist of evaporated coolant made it impossible to see from wall to wall. The men were issued specially lined gloves to handle the hot iron but the grease and the work wore them down in a day. Soon Johnson lost one finger and lacerated another. He had back, stomach, chest and head pains; he often felt nauseous...
...AFTER ENTERING, a notice Commands; the racks are full of familiar visages, the icons of one's childhood, Mickey and Pluto and the others blown up to preternatural size, then guillotined; their eyes goggle from the shelves like big affable poached eggs. There is even a set of coolant waistcoats, their design a spin-off from NASA; they circulate a chemical refrigerant round the body. In this humid and swampy acreage of Florida, every hot duck on Main Street contains a hotter man wildly signaling...
...erecting a second sunshade to protect Skylab's bare spot (cabin temperatures dropped as much as eight degrees into the low 70s). They also reloaded their solar-telescope array with fresh film and set up a micrometeorite-measuring experiment. Meanwhile, Skylab continued to be plagued by glitches. A coolant leak was discovered in one air-conditioning system, and suspected in another. A short circuit briefly troubled the telescope mount. Several external lights, intended for use during the space walk, failed to work, as did a video-tape recorder and an automatic camera. Skylab's on-board teleprinter also...
...their promise, many design problems must be solved before breeders can produce electricity on a commercial scale. One difficulty lies in handling the coolant-the liquid or gas used to transfer heat from inside the reactor's core to a steam-producing boiler outside. Unlike conventional reactors, which use water as a coolant, the so-called liquid-metal "fast breeders" planned by the AEC will use liquid sodium, which is an extremely efficient thermal conductor. But since sodium also burns in air and reacts strongly with water, it requires elaborate safeguards to prevent a mishap that could leak radioactive...
...scientific and military uses considered strategically important by the Federal Government. Helium has appeared on military embargo lists since before World War I, when the Allies used it in dirigibles.* Today it is used to lift weather balloons, to maintain pressure in liquid-propellant rockets and as a coolant in nuclear power plants. In liquid form, it provides supercool temperatures for laboratory experiments. Thus it seemed a sensible idea when in 1960 the Government, faced with possible shortages of the relatively scarce gas, set up a program to stimulate helium production. Instead, the plan has turned into the Great Balloondoggle...
