...chlorine, fluorine and carbon atoms, are nontoxic and inert, meaning they do not combine easily with other substances. Because they vaporize at low temperatures, CFCs are perfect as coolants in refrigerators and propellant gases for spray cans. Since CFCs are good insulators, they are standard ingredients in plastic-foam materials like Styrofoam. Best of all, the most commonly used CFCs are simple, and therefore cheap, to manufacture...
...first step toward doing that is to ban the production of CFCs, which are used to make plastic foam and as coolants in refrigerators and air conditioners. These gases account for an estimated 15% of the greenhouse effect. Another strategy is to burn as much methane as possible. That adds CO2 to the air, but getting rid of the methane is well worth it. Both gases trap heat, but as a greenhouse gas, methane traps 20 times as much heat as carbon dioxide, molecule for molecule...
Outside the powerhouse, near the dam, Buckley beams. He is hearing his favorite sound. Despite all his reservations about the bureaucratic process, he is upbeat. "They've taken a lot of the fun out of it," he says quietly, watching the black water roiling into white foam as it cascades over the steep rock cataract, "but it's still definitely worth doing...
...able to finish a 13-meter tall facade, and they will return to Mantua next June to complete the house, which is being built as an extension of the museum. The group is constructing the model on a wooden framework which Burns and his team covered with a plastic foam, painted to look like whitewashed stonework, Burns says...
That is why Kruse packed his three tiny planes on plastic foam bubbles in the back of his car and drove more than 1,300 miles across the U.S. to launch them for a few minutes of glory. For Kruse the urge is visceral, planted in him for good when, at age seven or eight, he hand-launched a 5 cents glider on ; the sun-drenched Kansas prairie. The craft rose a few feet, then miraculously was snatched by a thermal and carried away. Kruse leaped on his bicycle and rode desperately after it -- one mile, two miles, five miles...
