...Latin word fumariolum; meaning smokehole), and the simplest way to prospect for this geothermal energy is to look for such vaporous leaks in the earth's crust. But in areas where the energy remains trapped underground, geologists must use more sophisticated techniques. One method employs infra-red aerial photography. Since the infra-red film is sensitive to heat, geothermal areas are likely to show up lighter in the picture. Another method measures the earth's electrical conductivity, which increases with the presence of subsurface hot water. To tap the subterranean energy, engineers drill with standard oil rigs, going...
...mice nibbling at the roots and lower stems of one plant, which bears 40 to 50 artichokes. With an average of four mice per plant, the mouse population runs to well over 2,000 per acre. Fighting back against such hungry hordes, the farmers have resorted to aerial "bombing" of the fields with oats coated with a poison (zinc phosphide) that is strong enough to kill mice, too mild to hurt other wildlife. In one "Kill Mouse Day" last week, planes swooped down and dropped 46,000 lbs. of poisoned oats, which left countless casualties on the surface, others...
...OPEN SKIES," 1955. At the Geneva summit conference, President Eisenhower suggested a bold plan for aerial surveillance of all military installations, including nuclear facilities. The idea had not been favored by most U.S. military men, and the Russians rejected it as an espionage ploy. The Russians countered with a ground checkup system -which Eisenhower accepted in principle-but the idea fell through when Moscow would allow only three token look-sees a year. Today there is still no formal inspection procedure, although satellite surveillance and seismic detection devices have made it easier to keep track of nuclear installations and large...
...nighttime surveillance from aircraft, and military planners are developing bomb warheads that seek out targets illuminated by invisible infra-red laser beams. Peeling Potatoes. The various laser wave lengths, about 1,000 times shorter than those of the microwaves used in conventional radar, make laser altimeters, range finders and aerial mappers remarkably accurate. In a demonstration of a laser distance-measuring device, Spectra-Physics, Inc. flew the instrument over a Philadelphia high school stadium at an altitude of 1,000 ft. A conventional radar altimeter would have indicated only the slope of the stadium; the laser picked out each...
...they want their napkins tied around their necks, 18th century style. Best of all, they can wander beside ox-drawn carts along quiet, auto-free streets, amble through dozens of fragrant, carefully tended gardens, gaze over fields of maize or grazing sheep without seeing a telephone pole or TV aerial...
