Even as Los Angeles struggled with its auto-emissions problem, word came from Cambridge, Mass., about a more widespread future emissions problem: nitrogen oxides from the SST. During the 1971 debate that led to the cutting off of U.S. Government funds for the supersonic transport, environmentalists had voiced fears that nitrogen oxides in the exhaust of the 1,800-m.p.h. aircraft might weaken the ozone shield that protects the earth from an overdose of the sun's ultraviolet rays. The charge was serious, but was it true? The U.S. Department of Transportation commissioned researchers at the Massachusetts Institute...
...been to make things larger and larger, to the point where the great outdoors must itself become a museum. This has created a stock of homeless public sculpture-"monumental" but commemorating nothing except itself, kept in the warehouse by a scarcity of sites and the forbidding cost of transport and installation. What park could be given to these orphans? How could their possible relationship to landscape be tested? And what would be seen to happen...
...International Air Transport Association voted last week to boost fares on the North Atlantic an average 10% on Nov. 1, on top of three increases totaling 18% earlier this year...
...airplane and a lifting body (a shape giving aerodynamic lift). The proposed craft, which looks remarkably like a porpoise, was designed by a group of engineers organized as the Megalifter Co. of Goleta, Calif., after NASA'S Ames Research Center invited proposals for lighter-than-air ships to transport heavy, bulky cargoes. At the roots of its undersized wings, which resemble Flipper's flippers, are four jet engines with a combined thrust of 164,000 Ibs. There are also two small engines near the wing tips to control yawing and rolling. The 650-ft. hull would have...
...Channel Hops. In Britain, another group of engineers has formed Air-float Transport Ltd. to promote the "Airfloat HL" (for heavy-lift), designed by Surrey University Mechanical Engineer Edwin Mowforth. A VTOL (vertical takeoff and landing) model, it could carry a load of up to 400 tons and move it more than 1,000 miles at about 90 m.p.h. Airfloat's hull shape is conventional, and its propulsion depends upon old-fashioned propellers turned by ten turbines. Eight of them are amidships for forward drive and are also capable of exerting a vertical thrust of 40 tons. There...
