SOLAR ENERGY. Rooftop solar stoves, used to heat water, are found in Australia, Israel and Japan as well as in some areas of the U.S. Scientists now want to convert sunlight into electricity -a much more difficult task. One technique, proposed by Aden and Marjorie Meinel, a man-and-wife team of scientists at the University of Arizona, involves spreading a "solar farm," consisting of piping containing a mixture of chemicals, over 25 sq. mi. of desert. Heated by the sun, the mix would be used to make steam, which would power turbines capable of producing some 1,000 megawatts...
SUNSHINE. Theoretically, the sun's energy ought to be usable, but no one is sure how best to collect sunshine and transform it into power. In answer, Aden and Marjorie Meinel of the University of Arizona have proposed a "solar farm" that would cover 5,500 sq. mi. of desert with rows of black steel bands. These would absorb the sun's heat and send it to large storage "batteries" of molten salt, which would power turbine generators. Cost of building a 3,000-kw. demonstration plant: $10 million. Despite the amount of land that such projects would...
