...floor of the Red Sea. Near by lies a five-room underwater house looking like a huge plumbing joint made of chubby cylinders. Here seven pioneer oceanauts lived and worked 35 ft. below the surface for a month during the summer of 1963. Life in and around their pelagic tank town is the subject of this eerie, colorful documentary by Jacques-Yves Cousteau, a successor to his awesome epic, The Silent World...
...world's petroleum output. But as the sheiks grab bigger and bigger slices of oil revenues, producers have been busy developing alternative resources closer to the oil-hungry European market. The big gest of these now lie in the Algerian and Libyan Sahara, where drilling rigs, tank farms and smoke-plumed refiner ies give a modern industrial look to the ancient face of the desert...
...competition is also heating up. The oil industry already pipelines directly to such airports as Washington's Dulles, New York's Kennedy and Chicago's O'Hare, where jet fuel demand is heavy; it is also planning lines directly into neighborhood service stations to replace tank trucks, considering community tanks from which metered home oil burners could draw directly as gas burners do. For its part, the gas industry is pushing a "total energy concept," in which pipelined gas will do everything from generate electricity to cool air and heat water. Gas companies are already demonstrating...
Fierce Fluid. A typical hybrid is a comparatively simple product of a complex science. It is basically a pressurized tank for liquid oxidizer, behind which sits a combustion chamber lined with solid fuel. The two propellants are usually hypergolic-they ignite spontaneously when they come in contact with each other. A valve permits a jet of oxidizer to squirt into the rear chamber, combustion begins, and a hot, high-temperature flame roars out of the nozzle. The oxidizer valve can be used as a throttle to reduce the thrust and the engine can be stopped and started any number...
...hopped up with a high proportion of high-energy powdered metals or metallic hydrides, but in the absence of an oxidizer, they remain as inert as an auto tire. The oxidizer may be a fiercely reactive fluid such as OF2 (oxygen difluoride), but since it stays in its own tank until needed, it behaves itself. When the two components come together, they burn with extremely high specific impulse, the measure of rocket power. Best of all, say their boosters, hybrids are free of the complicated plumbing demanded by the liquids, and their inert fuel cannot cause an explosion. A solid...
