Peter M. Strait, a first-year at Columbia, said he was skeptical about the site’s future success. Columbia already has a similar webpage, the Columbia University (CU) Community, which has features unavailable on thefacebook.com such as an online journal...
...CU Community has exploded,” said Strait. “[On thefacebook.com], I felt my options were limited...
...reaching a record 686 billion kW-h last year. Nearly a fifth of all U.S. electricity is now generated with natural gas, and 88% of all new generating plants built in the past decade use the fuel. Meanwhile, U.S. production of natural gas has remained stagnant at 19 trillion cu. ft. a year, about the same as a decade ago. But the U.S. consumed 22 trillion cu. ft., up 8% during that time. Because natural gas moves more efficiently by pipeline than tanker (for which it needs to be liquefied), the difference comes mostly from Canada. Now the Canadians...
...same time that Louisiana factories are laying off workers because of gas prices, the U.S. is shipping gas to Mexico to generate electricity there. While the volume is still comparatively small, exports nonetheless have swelled 674% over the past seven years, to 263 billion cu. ft. last year. El Paso Energy, for one, pipes gas directly to the new Samalayuca II power plant, about 25 miles south of Ciudad Juarez. It serves 1 million people and some 300 factories south of the border...
...substance called aerogel, invented in the 1930s but recently refined by NASA, has been certified as the lightest solid in the world--yes, it's in the Guinness Book of World Records. Weighing in at a mere .00011 lbs. per cu. in. (thin air weighs about .00004 lbs. per cu. in.), aerogel resembles smoke that has been frozen into place--it's cloudy, translucent and virtually weightless. It's also surprisingly tough. Chemically similar to glass, aerogel is used on the space shuttle to trap tiny spaceborne particles traveling at high speed so they can be brought back to Earth...
