...string of sophisticated snooping devices on China's perimeter. Drone planes, high-flying U-2s and satellite cameras record roads, railways, steel mills, oil wells, nuclear plants, missile ranges and troop movements. U.S. Government analysts early spotted China's gaseous diffusion plant at Lanchow, the plutonium reactor at Paotow, and the atom-bomb test site at Lop Nor in the Taklamakan wastes of Sinkiang. They have predicted well in advance the timing of all three Chinese atomic explosions...
Ocean-Liner Luxury. The 980-ft.-long propeller-driven ship would be larger than any dirigible ever built and have a useful lift of 300,000 Ibs. Even so, it could be propelled at more than 100 m.p.h. by reactor-powered turbines that deliver only 6,000 h.p.-compared with the more than 40,000 h.p. needed to power a Boeing 707 jet. Such a reactor is already available; together with its shielding and turbines, it would weigh about 120,000 Ibs., substantially less than the weight of fuel alone needed for a long journey by a conventionally powered airship...
...achieving nuclear-powered flight in the near future. Though scientists and engineers have worked on plans for nuclear airplanes for more than a decade, they have yet to get off the drawing boards-let alone into the air. The big problems are weight and radiation hazard. A reactor big enough to power a 335,000-lb. 707 jet, for example, would require 225,000 Ibs. of radiation shielding to protect passengers-considerably more than the plane could lift. In the event of a crash, the high impact speed of the plane would almost certainly shatter the reactor, exposing anyone...
...with microcapsules containing primer. When the rivet is forced into place, the capsules break, allowing the primer to flow over both the rivet and the adjoining metal to protect them from corrosion. Manufacturers are testing encapsulated flavors and fragrances in food mixes to increase their shelf life, and nuclear-reactor fuel is being encapsulated to increase its efficiency...
Mostly, however, the presidents influence society and the Government by serving on powerful advisory groups. Within education, for example, 22 university consortiums now direct projects too big for any single school to handle, such as the operation of a nuclear reactor. Other key boards counsel the Government on foreign-aid, education abroad, relations with emerging nations, and poverty programs...
