...landscaping. The architect of the main stadium, Santiago Calatrava, insists he will need every minute until the opening ceremonies to finish his work. The $312 million central security system, designed to monitor everyone from pickpockets to al-Qaeda operatives, will not be fully operational. The nation's power grid is shaking like an old washing machine. Every class of laborer, from hotel employees to prostitutes, has threatened an Olympics-timed strike. Traffic barely moves...
...smelting plant, for which ground was recently broken in Reydarfjördur, a port on the country's largest east-coast fjord, will be Landsvirkjun's principal electricity customer. Excess capacity generated by the Kárahnjúkar power plant will be passed on to the national grid. The whole enterprise, says Arnalds, is "not only to create jobs locally, but to create national wealth." Iceland has an abundance of hydroelectric power, so the government is encouraging energy-hungry industries to settle here. But the country is also rich in natural wonders, and opponents of the massive development scheme...
...project popular across the political spectrum to build thousands of kilometers of canals that would link every river in the country. In theory, the network would allow engineers, with the help of gravity, to divert water from wet areas to dry as easily as power companies manage the electrical grid. Environmentalists are aghast. In addition to the phenomenal engineering and maintenance costs, as well as the corruption that such a megaproject might attract, they say the plan-which essentially throws more clogging dams and embankments at the problem-is simply bad science...
...main structural support, the Freedom Tower will also employ an increasingly popular triangular-grid trusswork. From a defensive standpoint, structural strength, even more so than fire safety, is the most important consideration for tall buildings. "A square is not a geometrically stable shape," says Childs. "A triangle is stable because it has a diagonal." The Trade Center towers fell because intense fires eventually melted their interior steel. But their structural systems permitted both towers to remain standing after the initial impact of massive jetliners. So for the new 52-story headquarters of the New York Times, the construction of which...
...kind at the Trade Center that were easily sliced by the intruding planes. "There are many ways," says Childs, "that this building is responding to the exact event that caused the tragedy." For its main structural support, the Freedom Tower will also employ an increasingly popular triangular-grid trusswork. From a defensive standpoint, structural strength, even more so than fire safety, is the most important consideration for tall buildings. "A square is not a geometrically stable shape," says Childs.
