...laws during an acrimonious divorce and, suffering from a heart ailment, lost touch with his clubs. In his heyday, Cooke made the trades (Wilt Chamberlain, Kareem Abdul-Jabbar), picked the draft choices, coached the coaches and chastised waiters in the Forum Club restaurant for allowing a guest's water glass to remain empty. The eye for detail paid off: the Lakers won the N.B.A. championship in 1972, and have remained one of the good, if not great, teams in pro basketball. The Kings have been less successful, but the Forum, dubbed "Cooke's Folly" by local detractors...
...most common solar devices, accounting for 95% of sales, are the flat, boxlike, conventional thermal units that sit on rooftops. These use the sun's rays to heat water, which in turn heats home water systems. A basic series of units for a one-family home costs about $2,000 and saves only about $40 a year in fuel bills. The promising new frontier is photovoltaics, the direct conversion of sunlight into electricity by using silicon-crystal panels. Though the price of photovoltaic cells has been cut in half since 1975, the cost is still $9 per watt,*equal...
...energy from the earth's hot interior, and DOE analysts believe that many Western states could start to follow this example. Geothermal energy exists in volcanoes, geysers and hot springs, and can be tapped by sinking wells roughly 2,000 ft. into the reservoirs of superheated water and steam that are sandwiched between layers of rock close to the earth's molten lava. Steam rises to the surface, where it can be used to power turbines that generate electricity, and is then allowed to flow back underground for natural reheating and reuse...
Hydro. Fifty years ago, the U.S. got a third of its electricity from dams. But many were destroyed or abandoned during the era of cheap oil, and that contribution has since dropped to less than 15%. But water power is now coming back into fashion...
Tidal power is being generated in small quantities in France and the Soviet Union. Long, low dams are built at estuaries, where the tidal rise and fall is large. The dams capture the water at high tide and let it run out through turbines at low tide. The catch is that power is generated only twice...
