Pollution Prods
Efforts to Harness
Earth’s Heat
More homes and factories in the future will draw pollution-free electric power from the heat of the Earth.
In Italy, Iceland, Japan, New Zealand, the Soviet Union, and the United States wells down to 8,000 feet already tap superheated water that bursts free as steam to spin turbines in generator plants.
The Geothermal Steam Act signed by President Nixon early this year opened 1,350,000 acres of government land in the American West to" exploration'and leasing for new geothermal power projects.
Recovery Methods Studied As utility companies seek to boost output while reducing pollution from conventional power stations, new ways of extracting the underground energy are being sought. One plan calls for detonating nuclear bombs more than two miles below the surface to create “chimneys” through hot, dry rock, the National Geographic Society says.
Water would be piped down to this natural boiler, recovered as steam to drive electric generators, then returned to be reheated in a recycling process. The plan is being studied by the Atomic Energy Commission. Present geothermal power plants-and one being built in Mexico-use natural steam from water trapped in porous sand above subterranean rock heated by molten magma at the Earth’s core. Scientists estimate some 168,000,000 cubic miles of heated water lie beneath the Earth’s
