...passage of electricity; since virtually no energy is lost, any electric device becomes far more efficient when built with superconductors. The catch is that superconductivity usually occurs only near 0 K (Kelvin), or -460 degrees F, which means the materials must be cooled by expensive, hard-to-handle liquid helium, thus sharply limiting practical applications...
...achieve superconductivity at even higher temperatures. Indeed, Paul C.W. Chu of the University of Houston and colleagues reached 98 K, or -283 degrees F, an achievement some physicists think should have earned Chu a share of the prize. That level of cooling can be achieved with more readily available liquid nitrogen. Suddenly, a wide range of applications seems economically feasible: trains that ride on a cushion of magnetism; smaller, faster supercomputers; more powerful medical imaging machines; and 100%-efficient power lines. The superfast train, notes Bednorz, "is a real dream of mine...
...first time I tasted it I thought I was going to be sick. The bitter black liquid was worse than the occasional sips I'd had of my father's beer...
...were they doing there? The answer, as Rowland and his colleague, Mario Molina, soon found, was that there was nowhere else for them to go but into the atmosphere. CFCs in aerosol cans are sprayed directly into the air, they escape from refrigerator coils, and they evaporate quickly from liquid cleaners and slowly from plastic foams...
...appears Velluci is disturbed because Harvard and MIT do not pay their share of the $1.07-per-household charge for removing liquid waste. Even so, City Manager Robert E. Healy indulged in a rare editorial comment, observing, "that's the beauty of it--you can get Harvard and MIT with the sewer usage charge"--from which nonprofit organizations are not exempt...
