Every year six tons of chlorinated hydrocarbons, 11,500 tons of heavy metals and 1.5 million tons of nitrogen from fertilizers are deposited in the North Sea by rivers and acid rain. An additional 250,000 tons of liquid chemical waste are dumped annually from West German ships into the sea. In Bonn Environment Minister Klaus Topfer last week refused to link man-made pollutants directly to the seal deaths, but he did admit to a "very serious suspicion" that industrial wastes may have played key roles. Topfer has promised to end offshore dumping by the end of 1989. Environmentalists...
Environmentalists and engineers know that hydrogen would make a better jet fuel than the standard aviation kerosene. In its liquid form, hydrogen packs more energy per pound than any other non-nuclear fuel and, burning, produces a plume of H2O. But there are major drawbacks, including cost. Extracting hydrogen from water or natural gas and cooling it to -423 degrees F make the fuel many times more expensive than kerosene, which goes for about...
...interest in the novel fuel has been rekindled by news that the Soviets have conducted a successful test flight of a Tupolev Tu-154 passenger jet modified to burn a mixture of liquid hydrogen and natural gas. The three- engine jet, which lifted off near Moscow and flew for 21 minutes, was the first aircraft to use the fuel in takeoff. Says Senator Spark Matsunaga, a Hawaii Democrat and a leading advocate of a U.S. hydrogen-fuel research program: "It appears that the Soviets have stolen a technological march...
Meanwhile, the technology continues to spread. Rods and reels now sport built-in microcomputers and liquid crystal display screens. Ryobi America of Bensenville, Ill., for example, makes a $95 bait-casting reel with a computer that monitors the spool's rate of spin during casts and adjusts it as necessary to keep the line from getting snarled. Daiwa of Garden Grove, Calif., sells a $100 spinning reel with a screen that tells how far the line is cast and how fast it is reeled in. The $695 Cannon Digi-Troll, sold by Michigan-based S & K Products, not only drops...
