...from NASA's Goddard Earth Observing System Data Assimilation System - a network of complex computer systems used to simulate and predict meteorology - McElroy and his colleagues could map the distribution of wind resources around the globe, then calculate how much electricity could be produced by tapping those breezes with current turbines, which can generate about 2.5 megawatts on land, and larger turbines that can generate 3.6 megawatts offshore. (Offshore winds tend to be stronger and more constant than land breezes, hence they generate more power...
...results show that there's more than enough wind to go around, and not just in breezy, big countries like the U.S. Even land-limited Japan can produce more than three times its current electricity consumption with wind power, provided it taps offshore wind. The problem isn't supply but distribution: in the U.S. and elsewhere, some of the richest wind resources tend to be far from the densely populated coastal areas that need the most electricity. Another problem is intermittency - even in Chicago, there are days when the wind doesn't below. But both those hurdles can be sidestepped...
Galvin declined to comment on the cost savings achieved by the cuts, but said that the layoffs announced today represent a "significant step" in aligning Harvard with its current fiscal reality. He added that while administrators "do not have any current plans for additional University-wide reductions," the need for further budget cuts could not be ruled out as Harvard reshapes itself in a volatile global financial environment...
Kennedy School Professor Emeritus Marvin Kalb, whose area of expertise also includes Iran, also said he does not see a new regime taking charge, even if the current structure will have to accommodate new realities. “No matter what happens over the next couple of weeks and months, the government of Iran cannot stay the same,” Kalb said...
...economy: health costs are bankrupting small businesses and even conglomerates like General Motors as well as millions of families. And it's awful for the country: Medicare is on track to go broke by 2017, and our long-term budget problems are primarily health-cost problems. At current growth rates, health spending by the Federal Government alone would increase from 5% to 20% of the economy by 2050; Social Security, by contrast, would increase only from...
