Nuclear power is just another way of boiling water: An atomic reactor sustains a fission reaction which produces heat used to boil water which drives electric turbines in the same way as in traditional, coal-fired plants. All coal contains traces of radioactive carbon, which is released when coal is burned. Recent studies suggest that boiling water reactors will leak over 14,000 times the amount of radioactivity produced by coal burning. Such a reactor is also only about 20 per cent efficient, which means over 80 per cent of the heat generated is wasted and must be released...
Another view frequently aired was that Pusey and Bok should look outside the Law School for the next dean. "We need a fresh perspective," Doug Castle, a second-year student, said. "And we don't want a carbon copy from the outside either. Someone with fresh ideas is not going to sink the Harvard Law School, but he may give it a few bumps and that could be all it needs...
There will also be some secondary effects from the mangrove destruction. Villagers in the south relied on the mangroves as a major source of wood for fuel and charcoal. Mangrove-lined waterways provide food and nursing grounds for fish and crustaceans, too. Mangroves are active photosynthesizers and fix carbon into an organic form the fish can use. The HAC was unable to estimate the magnitude of this function but suggested that its impact on the fishing industry deserved study...
Tillinghast staged the demonstration to show the industry's progress in curbing air pollution by modifying jet-engine combustion chambers to burn a leaner fuel on takeoff. This eliminates smoke, though not invisible gases like carbon monoxide. TWA is spending $2,000,000 to alter its engines this way; all U.S. airlines are pledged to achieve smokeless takeoffs by 1973, which may cost the lines as much as $100 million...
Late and Broke. The development problems quickly escalated beyond Rolls' calculations. To keep the engine's weight down. Rolls engineers planned to make the RB-211's fan blades out of lightweight carbon fibers. But the fibers could not stand the crunch when hail or birds were sucked into the 7-ft. fans. Last April, Rolls managers decided to keep working on the fibers but to forge the fan blades for the first few engines from titanium; this meant that they had two expensive development programs going. As time to deliver the engines ran short, Rolls started...
