...dirtier. HEW officials think the danger can be kept to a minimum by strict adherence to federal clean-air, safety and waste-disposal standards, but concern persists-with reason. Reacting to it, Washington is virtually certain to require all coal-burning plants, even those that burn low-sulfur Western coal, to install "scrubbers" that cleanse coal smoke. That is one reason why the cost of converting to coal will be so high...
Many of Guam's regulations reflect U.S. domestic politics more than common sense. The Environmental Protection Agency orders power stations to use low-sulfur oil even though the island is washed by a brisk 10 m.p.h. trade wind that blows away pollution. The Jones Act requires that all commodities shipped between U.S. ports be carried on U.S. vessels. The former rule adds $10 million to Guam's annual fuel bill; the latter has made the island's economy vulnerable to longshoremen's disputes that take place thousands of miles away. "We're always...
...famed Cavendish Laboratory at England's Cambridge University, provided the theoretical underpinnings of modern solid-state physics in the 1920s. His later work with amorphous materials led to development of the "Mott model," a theoretical framework for understanding the properties of semiconductors made from amorphous materials such as sulfur, selenium and tellurium, all of which are far more economical to produce than crystalline components...
...Rice, maize and potato crops in the area were destroyed. Tourist hotels shut down as residents of the island began digging out. Before Usu rests again, it could throw out much more debris. Japanese volcanologists report that columns of smoke mixed with steam and smelling heavily of sulfur are still rising from four new craters created by the recent explosion. They warn that the volcano, which has already caused some $80 million in damages, could erupt again at any moment...
Since it breezed through Congress in 1970, the Clean Air Act has significantly improved the atmosphere Americans must breathe. Sulfur dioxide levels are down by 30% and sooty particles by 33%. Cars, too, are less polluting as Detroit struggles to meet tough emissions standards. Yet for all the progress, air quality in most major U.S. cities and industrial regions is still below the goals set seven years ago. Now a drive to clear the air has set off the fiercest environmental fight in years...
