...form of small shipments made to Boston's Distrigas Corp. to supplement supplies during New England's chilly winters. But from next week on, one of a fleet of nine El Paso tankers will deposit LNG at Cove Point roughly every 60 hours. There, the supercold liquid, which arrives at a temperature of 259° F. below zero, will be heated until it turns back into gas, then piped through the networks of Columbia Gas System and Pittsburgh-based Consolidated Natural Gas Co. to 7 million Eastern customers...
...improvement in methods of generating and transmitting electricity. One remedy is an advanced but until recently neglected system with the awesome name of magnetohydrodynamics. MHD can produce electricity directly from the high-velocity flow of hot, ionized gases, with 60% efficiency instead of the present 35%. Similarly, superconductive, supercold (-320° F.) power lines can cut transmission losses. Though both technologies are costly, they would yield much more power per unit of fuel with less pollution...
...less than a minute, one of the service module's two spherical oxygen tanks was completely empty; nearly 320 Ibs. of supercold ( -297° F.) oxygen, a highly pressured mix of gas and liquid, had gushed out of the spacecraft, apparently through a rupture in its thin alloy skin. Looking out of his window, Lovell could see vapor streaming by. "We are venting something into space," he reported. "It's a gas of some sort." At the same time, the spacecraft began to pitch and roll in reaction to the violent expulsion...
...Pollution-Toward a Cleaner Car" [Oct. 17]: natural gas is certainly a clean-burning fuel. However, for automotive use it must be stored as a cryogenic (supercold) liquid in a large, well-insulated tank. Unfortunately, if you do not drive a large number of miles in a relatively short time, the liquefied natural gas boils off. If your car sits in the driveway for a few weeks while you're on vacation, you may return to find your fuel has evaporated. Not only is this bothersome and expensive, but I suspect this evaporated hydrocarbon fuel may pollute the atmosphere...
...cell's hydrogen and oxygen are both stored in spherical tanks in a supercold liquid state. Warmed by electric heaters, they turn to gas, build up pressure and push themselves into the cells. And those heaters are among the least complicated devices on the spacecraft: a filament of gold-plated wire curving around the tank. The same type of device is a veteran of all the manned Mer cury and Gemini flights, being used to convert liquid oxygen into gas for the astronauts to breathe. When oxygen pressure started falling in Gemini 5, it was a sure sign that...
