...shortages of any kind. Shiny new appliances, from electric rice cookers to transistor radios, occupy conspicuous nooks even in the homes of unskilled laborers. Television antennas rise everywhere, even over tin-roofed huts. Saigon's greenery has suffered less damage from Communist bombs than from the choking exhaust fumes of Mercedes autos and Honda motorcycles...
...crumbling surfaces of medieval figures, many without heads or hands, emanate a sense of the centuries they have endured. Revolutionaries knocked them from cathedral walls: some have lain buried: wind has eaten away at others; now the exhaust from tourist buses threatens them with ruin. In their present state, where moments of perfect carving flow between interruptions of broken stone, these pieces symbolize our fragmentary knowledge of art of the Middle Ages...
...power of their high-performance cars as one result of new federal pollution requirements. If so, the "muscle" cars like the Mustang Mach 1 and the Buick Grand Sport 455 will no longer have the kick that enables youngsters to roar away from the stop lights, tires smoking and exhaust pipes blasting. Big engines on luxury cars probably will be somewhat less powerful. The current high-powered cars are likely to have lower-compression engines designed to burn the unleaded gasoline of the future...
Taking the lead out of gasoline appears to be a necessary step in cutting down air pollution caused by automobile exhaust fumes. Though not one of the major air pollutants itself, lead befouls most present-day antipollution devices. President Nixon, in his message to Congress last week (see ENVIRONMENT), proposed strict new Government standards to eliminate virtually all auto-caused pollution by 1975. Detroit could accomplish this by replacing the internal-combustion engine with hybrid cars that combine a small gas engine and an electric motor, or engines that run entirely on electricity, steam or even natural...
...intends to make extensive changes in existing ones by building in antipollution devices. These could raise the price of the average new car by 10% or more -but that is not the most immediate problem. The key antipollution device is the "catalytic converter" that burns up hydrocarbons in the exhaust. The trouble is that the converter is eventually gummed up and rendered useless by the tetraethyl lead in present-day gasolines...
