...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 to a staggering $40,000 for a one-family home. Still, advances are being made in the efficiency of panels and methods to store power...
Through early-morning hints of sunlight, the Harvard fortunes had proceeded well enough. All six boats had qualified for the finals, five of the six winning their heats. The super-psyched varsity lights had posted a time six seconds better than any other crew on the course that morning. It was nothing unexpected, but at least it wasn't disappointing...
...sisters sing in pure, clear voices that shine like sunlight on a spring lake, but the songs are often dark. "There's a bitterness there that won't go away," Maggie acknowledges, a feeling that may have come in part from some bruising years on the folkie circuit and a wrangle over a first album (released by Columbia in 1975). When the record came out, and bombed, Maggie and Terre were hiding out in Hammond, La., waitressing in the Magnolia Restaurant and living at a friend's Kung Fu temple, where they picked up a few rudiments...
...well as large, and industries besides oil will get a chance to test daring ideas. Oil companies should not be encouraged to try to dominate, or monopolize, whole new alternative-energy industries that come into being to compete with petroleum. In such esoteric fields as the direct conversion of sunlight into electricity and the extraction of gas from sea water and oil from coal, companies in other industries?electronics, mining, shipbuilding?have as much expertise as the oil industry and, in some cases, more...
...sales are for conventional thermal devices that use the sun's rays to heat rooftop water panels, which in turn heat swimming pools and home water systems. But the exciting side of the industry that is attracting the larger companies is photovoltaics?the direct conversion of sunlight into electricity. The theory is simple. A wafer-thin, 3-in. to 4-in. plate or "cell' that is sliced from a chemically treated silicon crystal will give off direct-current electricity when exposed to light. The amount that comes from each cell is minute, but many cells can be wired together...
