...with the ribbons of concrete and macadam that twine and tunnel through the U.S. Superhighways are a brand-new form of functional art, with elements that differ from the construction of any roads in history. The wrong kind of curve can be dangerous when one is moving at more than a mile a minute, and no curve at all can be lethal. The new art-science of freeway design forms the most original section of a new book called Man-Made America, by Planners Christopher Tunnard and Boris Pushkarev (Yale...
Aiming the driver's eye is important as an antidote to one of the special hazards of freeways-the "tunnel vision" that sometimes leads to hypnosis and sleep. It is also vital to give the driver some means of instinctively judging his own speed, a task that is accomplished by houses, signs and other clutter along the traditional roadside. This may be accomplished on the new freeways by angling the road for views of industrial plants, valleys, water towers, or even pieces of giant sculpture, to contrast with the "green corridor" of the countryside...
Northrop engineers, who have run thousands of hours of wind-tunnel tests, say that once the suction is started, there is smooth, laminar flow over both top and bottom of their new wing. Up to 80% of the friction drag is eliminated-and this figure includes compensation for the drag caused by the nacelles and for the power needed to run the turbines. With drag so drastically reduced, an airplane uses much less fuel, thus can fly farther or carry more payload. The null will not have its first flight tests until next month, but Northrop is already making...
...cheap electric power. Harnessing the remote Saguenay River, Aluminium cut into the trackless wilds of northern Quebec to build the dams that now power the smelter at Arvida (a contraction of Arthur Vining Davis). For the still bigger Kitimat power project in British Columbia, it carved a ten-mile tunnel into a mountain, created a waterfall 16 times as high as Niagara Falls and built a smelter with an awesome annual capacity of 300,000 tons...
Actually, the expense is not as high as it might seem. Adds Obie: "The whole shebang-lot, tunnel, subway cars, the works-costs us only about $200 per parking space." Other downtown merchants, anticipating the Leonards' bringing customers painlessly into the area, have begun sprucing up their own store fronts to attract as many as they can. The Leonards don't mind, since they have first crack at riders of their private subway...
