Under the law, emissions of two noxious gases in auto exhaust-carbon monoxide and hydrocarbons-must be cut by 90% of 1970 levels in 1976-model cars. Techniques to do that, however, lead to an increase in a third pollutant, nitrogen oxides. The law says that, in 1977-model cars, they must be cut 90% below the level in the 1971s. Most auto engineers feel that they cannot meet that second deadline...
...year if he deems it necessary to do so. The automakers can use the grace period. They have already gone about as far toward cleaning up their cars as they can, without introducing costly new technology. GM, for example, reports that it has reduced emissions of hydrocarbons by 80%, carbon monoxide by 70% and nitrogen oxides by 40% since 1967. Such progress, gained by making adjustments on the standard Detroit engines, has been bought at the expense of fuel economy and auto performance: most new cars are hard to start, balk when rapidly accelerated and cough for minutes after...
...California and wherever else the automakers wish. According to GM, this "catalytic converter" will improve gas mileage by up to 13% and make cars perform as well as in the good old days. Shaped like a muffler and attached to the exhaust system, it will also convert hydrocarbons and carbon monoxide into water vapor and other harmless compounds...
...that she is a superb female impersonator. Not, however, as good as Rodney Pigeon. The following night at the Blue Angel nightclub, Rodney, 20, scored a succèsfou in the French-inspired transvestite revue Zou. Hurling himself onto the pocket-handkerchief stage, the divine Miss M's carbon copy skittered and tittered while belting out Midler's theme song, Friends...
Comets, in fact, are nowhere near as large as planets. Their central structure, or nucleus, is usually no more than a few miles in diameter; it is believed to consist largely of frozen gases-mainly water vapor, methane, carbon dioxide and ammonia, and perhaps some hydrocarbons-and dust particles. That, at least, is the commonly accepted "dirty snowball" theory, originally proposed by Harvard's Whipple in 1950. But there are those who take exception to Whipple. British Astronomer Raymond A. Lyttleton prefers his own "gravel-bank" theory, which holds that the cometary nucleus is really a loose mass...
