...thing, the power is almost entirely free (only 13 kilowatts of electricity are needed to operate the mirrors). More important, the furnace gives off what he calls "aristocratic" or uncontaminating heat; there is, for example, none of the adulterating carbon that is produced by the hot electrodes in ordinary high-intensity electric arc furnaces. Thus the solar oven is ideal for the production of chemically pure materials...
Time Clock. Plastics contain tough carbon chains that are often 10.000 times longer than those found in ordinary molecules. Some scientists estimate that it may take a million years before microorganisms capable of attacking the man-made material can be produced in nature. Rather than wait, some chemists have infused plastics with chemical "time clocks": automatic decomposers. But there was no way of controlling the rate of decomposition, say weeks for cups, and years for auto taillights. Nor did manufacturers want a plastic that could disintegrate on the shelf or in a customer's hands...
Guillet's team got around such problems by finding a way to chemically bond groups of "sensitized" molecules directly into the plastic's carbon chain. When these "S" groups absorb ultraviolet light from direct sunlight, he says, their carbon "backbones" soon begin to be decomposed by microorganisms. But indoors-even in front of glass windows-they will not be affected. Guillet claims that the speed of the breakdown can be controlled by varying the number of "S" groups bonded into the plastic molecules. He also thinks that the process would raise the price of plastics by only...
...Powers of Ten, one such idea film that Eames presented in 1968 to ameeting of America's top physicists, sketches a linear zoom to the farthest known point in the galaxies down to the nucleus of a carbon atom. What makes the film almost surreal at times is the starting point- the wrist of a man lying on Miami Beach- and the narrator, a serious female voice. Yet, whether physicist or child, one gets a feeling for the dimensions of time and space...
...explain its efforts on the pollution front, only to be faulted. It ran an ad in more than 100 U.S. newspapers claiming that "G.M.'s 1970 model cars, as equipped for California use, achieve reductions of more than 80% on hydrocarbons and reductions of more than 65% on carbon monoxide emissions compared with 1960 cars without such controls." When questioned about that by newsmen, John T. Middleton, commissioner of the National Air Pollution Control Administration, said: "General Motors' record for compliance with the Government's emission standards for carbon monoxide is poorer than that for other...
