...transfers will be allowed at least until Jan. 1, to give Congress time to liberalize the laws. There are many other sources of liquid assets. The increasingly popular money market mutual funds, unlike conventional securities, permit holders to draw out their money immediately and put it to use...
Nearly 90% of all 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...
...confined to remote and inaccessible locations where the costs of providing conventional power are prohibitive. For example, in California solar cells generate energy for Coast Guard buoys, rural water pumps, VHF telecommunications relay towers, automatic weather stations and even an Air Force radar station. In addition, Kansas oil wells use solar electricity to inhibit the rusting of metal; a remote Arizona Indian reservation gets its power from cells, and even the Saudi Arabian government plans to line its Jidda-Riyadh highway with 400 solar-powered emergency call boxes...
...cells is also rising. Ten years ago, they could convert to electricity only 2% of the theoretical average 100 watts of the sun's energy that falls on a square foot of earth; now they can convert 16%. To intensify the sun's rays, the Los Angeles project would use parabolic and elliptical cells instead of flat ones. Arco Solar and other companies including Exxon, Mobil and Shell are working in intense rivalry and secrecy on such matters as improving storage batteries, finding better materials to substitute for silicon and even mass-producing flat "ribbons" of silicon to replace...
There followed a period of drifting, to California, to Florida, but always back to Washington. He discovered how to use his fists, hung around with pugs (Jack Dempsey is still his best friend), boxed as an amateur and as a sparring partner. To his mother's horror, he accepted a bout as a professional, and won. But haunted by his father's nomadic, and futile, search for economic security, he returned again and again to law school, until on the last try he earned a degree...
