...over your head, you may wonder whether you are still in Zurich. And that's how the zoo's director, Alex Rübel, intended it. Opened in June 2003, after a decade of planning and construction, the j33.5 million project boasts such high-tech features as light-sensitive roof foil that maintains high temperature and humidity, a waterfall and man-made rain from sprinklers pouring up to 80,000 liters of water a day. Some 17,000 species of plants and 2,500 trees were brought in from Madagascar...
...constituted in Kuwait will still be in country in 2004. For missions outside the wire, the Tomb Raiders borrow soldiers from other platoons, but they have to carry out their routine duties--monitoring the radio, maintaining vehicles, staffing the battalion's Internet cafe, manning guard positions on the roof--with fewer soldiers, straining their combat effectiveness. "Maybe we don't have enough personnel," Van Engelen says. "Maybe if we had more, they'd get more rest. Maybe they'd be more alert and energized when they went...
What is noticeable, if you look closely, is the wide-eyed look on the face of my young brother--a child who still believes he will hear during the night "the prancing and pawing of each little hoof" when Santa's sleigh clatters across the roof. My expression is different. I am snagged on the outer edge of childhood--old enough to know there is no Santa Claus and clearly already practicing that disdainful attitude which, in a few more years, I would turn into an art form. You can imagine my father reading the story in a fresh, expressive...
What about that other long-promised alternative-energy source, solar power? Technology Pioneer Nanosys of Palo Alto, Calif., thinks solar's day in the sun has finally arrived. The firm is developing tiny photovoltaic cells that can be incorporated into the fabric of roofing materials to provide power to homes and other types of buildings. Nanosys is combining the science of solar cells with the science of nanotechnology, which manipulates items as small as an atom to do everything from switching electricity to storing data to sensing the movement of a bridge that is beginning to weaken. Thanks to this...
...single square meter of the solar-ready plastic will cost about $100 and last about 20 years, so a complete roof would cost a few thousand dollars. Nanosys' co-founder and head of business development, Stephen Empedocles, says that's a good investment, since the tiles will generate electricity at a cost of about 4¢ per kW-h, well below the 20¢ to $1 for traditional solar panels...
