...chief technology officer of Microsoft and co-founder of Intellectual Ventures, a private think tank. Myhrvold and his staff have the idea to build a giant "garden hose to the sky" that would pump liquefied sulfur dioxide into the atmosphere. Scientists know that increasing SO2 in the air deflects sunlight, which cools down the earth; when Mount Pinatubo in the Philippines exploded in 1992, for instance, the SO2 sent into the atmosphere created a brief global cooling spell. Levitt and Dubner advocate pursuing this geoengineering scheme, which could potentially avert a hotter world for pennies on the dollar, compared with...
...lines between sectors are blurring fast. As its name suggests, eSolar is essentially a software play; its added value is advanced code that positions vast arrays of mirrors to the millimeter to maximize their exposure to sunlight. The company was spawned by IdeaLab, a Pasadena incubator that developed NetZero, Picasa, pay-per-click ads and online car-selling. "We only do ideas that challenge the status quo, and California is the only place we'd do it," says CEO Bill Gross. (See pictures of San Francisco...
...Indoor Tanning Association (ITA) dismisses such charges as mere ballyhoo, pointing out that the UV light from tanning beds is no different from sunlight - exposure to either one raises the risk of skin cancer - which is why the tanning industry has always emphasized the importance of moderation, says John Overstreet, executive director of the ITA. He adds that technicians at tanning salons are trained to prevent overexposure and sunburns. "If clients get a sunburn, they are not going to come back," says Overstreet...
...waste powder made of calcium carbonate and other impurities from the marble. Some 100 factories in the area leave large tracts of the white stuff, which not only contaminate the air, the ground and eventually the waters, but also cause the huge areas of white to reflect the sunlight, creating their own micro-climatic-warming effect in the valleys of the Aravalli Range that form the basin of Udaipur...
...Moisture found in rocks brought back by those early missions were thought to be the result of contamination from the earth's atmosphere. The new research, which used the intensity of the colors that bounce off the surface of the moon when it's hit by sunlight, proves that there are traces of both water and a closely related molecule called hydroxyl. Scientists now believe water could be produced in the lunar soil when hydrogen from solar winds combines with oxygen-rich substances on the lunar surface. Another theory centers on water-laden comets and meteorites hitting the moon...
