...such cities as New York, Chicago, Sacramento and Milwaukee. One of the latest to switch to garbage power is Hempstead, N. Y., which has set up a $73 million plant on Long Island that will consume 2,000 tons of waste a day and generate up to 40 Mw (megawatts), enough electricity for 15% of the residential needs of Hempstead's 865,000 population...
Union Oil Co. has built one of the first U.S. geothermal power stations at Geyserville, Calif., 90 miles northwest of San Francisco. It sends 608 Mw, 2% of California's electricity, to Pacific Gas and Electric's utility grid, enough to power 500,000 homes. The cost is only 1.80 per kw, and Union Oil optimistically suggests that by 1990 geothermal energy could provide 25% of California's electricity...
...number of states are surveying their rivers to measure the hydroelectric potential. A study by the U.S. Army Corps of Engineers concludes that there is an untapped power supply of 40,000 Mw from new and existing U.S. dams that have been allowed to fall into disuse, enough to power 100 cities the size of Washington. By some estimates, if all the hydro sites now under study could be repaired, they would yield the energy output of 16 nuclear plants for the cost of only 2% new nuclear plants...
...waves falling on a mile of beach contain an estimated 65 Mw of power, but that force is difficult to harness. The British, French and Japanese are working on wave-power projects. Most involve some kind of rafts hinged together by pistons; the rocking motion forces the pistons to pump water that turns turbines. A different U.S. plan, now being studied by Lockheed, would use a 250-ft.-diameter man-made "atoll" tethered at sea. Looking like a giant doughnut, it would float with its top just above the surface. The waves surging across the rim would flow down...
...Soviets are going nuclear quickly. They now have four pressurized water reactors, with a rated total capacity of 1,440 Mw, on line at Novovoronezh. A fifth, designed to produce 1,000 Mw, is under construction, and several more 1,000-Mw plants are planned...
