...improve the performance of a rocking chair, it will not improve the efficiency of an automobile. Performance of a vehicle will not be affected until it reaches at least 50 m.p.h. With a national highway speed limit set at 55 m.p.h., aerodynamically "slippery" cars designed to achieve better fuel economy are meaningless...
Diesel may not be the way to go. Given the high aromatic content of diesel fuel and its propensity for creating particulates, chemical intuition suggests that it would be surprising if diesel exhaust did not contain appreciable amounts of first-rate carcinogens. As a professor of physical chemistry, I for one would like to see the medical studies precede deployment this time...
...industry's and government's confidence of old; reappraisal and caution would now be the order of the day. The unthinkable had come perilously close to happening, causing second thoughts about the form of energy that promises to relieve dependence on ever diminishing, ever more expensive fossil fuel supplies...
...reactor pressure, which made them believe that the core of enriched uranium was covered with coolant when it was not. The operators switched off the system on the assumption that it was no longer needed. The premature shutdown and temporary loss of coolant caused the reactor's fuel rods to overheat. They reached a temperature of around 2,500° F., which could have led to a meltdown. Water pouring into the reactor overflowed to form a 250,000-gal. lake on the floor of the reactor building. Some of this water, laden with highly radioactive products, was pumped...
Still unsettled-and unsettling-is the question of how the U.S. can safely dispose of garbage from nuclear operations. Spent fuel and other wastes remain radioactive for thousands of years. At present a lot of such waste is stored under water in "swimming pools" at plant sites, but nuclear plants are running out of pool space. Some may have to shut down as early as 1983 unless a more permanent method of disposal is found. Nuclear plants are built to operate for about 35 years. By the year 2000 some worn-out ones will either have to be torn down...
