...Slick. Going to the source of the problem, Rosenberg and Gutnick last winter boarded a 125,000-ton tanker to give RAG1 a practical test. Selecting two of the ship's tanks, which were each filled with 100 tons of sea water, they poured 55 lbs. of nitrogen-containing urea and 2.2 lbs. of potassium phosphates into each. Shipboard compressors were used to bubble air into the tanks through a perforated hose, thus turning them into ideal "bacterial fermenters," says Rosenberg. Then a flaskful of RAG1 bacteria was poured into one tank. Six and a half days later...
...with high-pressure hoses; the nozzles sometimes develop charges of static electricity that can ignite oil fumes lingering in the tanks. Moreover, Rosenberg believes that his bugs may turn even the ballast water into profit. He figures that after the bacteria have cleaned the tanks in a 200,000-ton supertanker, the ballast could yield some 200 tons of dewaxed oil (which can be made into gasoline and other petroleum products). Beyond that, they can be harvested to produce about 150 tons of high-quality animal food...
...near by, it appears, from the model, to resemble a butterfly with long feelers or a tulip bending its petals to earth. "Not at all," retorted the 74-year-old artist. "It's more like a flamingo." Even so, Calder has had to redesign part of the 10-ton carbon-steel structure. "This is supposed to be a stabile," he explained, "but with Chicago's wind, we have to be careful it doesn't become a mobile...
...vast amounts of shale found in Colorado, Utah and Wyoming could also be important sources of oil, yielding about 25 gallons for every ton excavated. Both shale mining, which leaves great quantities of waste material above the surface, and strip-mining for coal despoil the landscape. But the exploited landscape could satisfactorily be restored-at a price...
...night three miles south of the Cambodian border. Two 75-mm. cannon and a B40 rocket scored direct hits on the vessel's superstructure. Two tankers on Lo's stern caught 14 rockets. When Lo looked back, he saw a smaller cargo vessel, the 1,500-ton Ally, burning and beached on the riverbank. In all, ten of the 18 vessels in the original convoy decided to turn back to An Long...
