Youngsters roll on the ground, tussling, teasing each other and gleefully aping their elders. They climb the tropical trees with abandon and plunge happily into cooling water-holding their noses when they dunk. Despite the similarities, the equatorial playground, at the edge of a 12,000-acre forest preserve on Borneo is no boys' camp. It is the Malaysian state of Sabah's experimental center for the rehabilitation of orangutans...
While chasing a grizzly bear one day in 1847, Explorer-Surveyor William Bell Elliott blundered into a canyon that looked to him like "the gates of Hell." Huge, spiraling columns of steam hissed out of the ground; the earth trembled beneath his feet. "The Geysers," as he named the hill-rimmed valley 85 miles north of San Francisco, is as awesome as ever. But its frightening bursts of steam are now being harnessed. The canyon is the site of the first commercial geothermal-power plant in the U.S., and the installation has paid off so handsomely in eight years...
Occasionally steam emerges through fissures in the ground called fumaroles (from the 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...
...geothermal energy could be generating as much as 10% of the total electrical output of the U.S. And no matter how much is used, the heat is not likely to be used up. Once scientists master the technology, they should be able to recirculate condensed steam back into the ground, giving virtually unlimited life to wells in states as dry as Nevada. Even without such re-circulation, Italy's 64-year-old Larderello geothermal-power plant near Siena, where fumaroles gave Dante earthly inspiration for his Inferno six centuries ago, is still going strong...
...city for so long that they have been forced to go to Gander to refuel. Domestic flights from the West Coast to New York were placed in holding patterns as far away as Denver. One Northeast flight, originating from La Guardia, had to refuel after waiting on the ground for 2½ hours, resumed its place in line and waited two more hours before canceling. In a single day, Mohawk Airlines logged 84 hours of delay...
