...delay gave everybody time to think. Arcata still needed an alternative disposal system that would "enhance" Humbolt Bay. Its sludge-skimming plant piped the city's wastewater into an oxidation pond (where most microbes are rendered harmless by sunlight), but the runoff no longer met legal standards. Locals knew vaguely that wastewater had some environmental pluses. Humboldt Bay oysters fed on its nutrients, and Professor Allen, a likable tinkerer whom Klippity Klopp calls Crazy George, raised salmon fingerlings in a mix of sea and wastewater. Other ideas emerged. HSU biologist Stan Harris was for a bird sanctuary. Gearheart came...
...tunnels and filled with such facilities as offices, gymnasiums, libraries, exhibition halls and public baths. The project would be built 164 ft. below the ground, sprawl across 485 sq. mi. and accommodate 500,000 people. Not only would temperature and humidity be controlled, say the planners, but real sunlight would be reflected in through vents from the surface. Estimated cost: $80.2 billion...
...expert who requests anonymity says of the whole idea, "This will be one of the great disasters in New York history. It will be a disaster of historic proportion because it will shape the look of New York for generations. It's not just that it will blot out sunlight, it will blot out values." And, argues Marshal Berman, a political-science professor at the City University of New York, it will substitute the values of "Dallas and Dynasty, people wearing diamonds and furs and being driven around in limos. The vision is of New York as an international center...
...earth's surface inflicts plenty of damage: besides causing sunburn, the rays have been linked to cataracts and weakened immune systems in humans and other animals. Ultraviolet light carries enough energy to damage DNA and thus disrupt the workings of cells, which is why excessive exposure to sunlight is thought to be the primary cause of some skin cancers...
...wind and hydroelectric power can be generated at only a relatively few sites, and so governments should redouble financing for research to develop efficient, low-cost photovoltaic power. Photovoltaic cells, which produce electric current when bathed in sunlight, were briefly in vogue during the energy crises of the 1970s, and while public attention and Government funding have waned, research into the technology has continued. "The capital costs have come down from about $50 a peak watt to $5," said Speth. If they drop to $1, solar power will become competitive. That could happen without significant Government research support...
