Carpet Or Paint

clipped from www.nytimes.com Big arrays of mirrors that concentrate sunlight to run turbines, which first emerged in the early 1980s, are resurgent in sun-baked places like the American Southwest, Spain and Australia. Some developers say this solar thermal technology is competitive now with power generated by natural gas when demand, and prices, hit periodic peaks. With more research, the solar thermal method might allow for storing energy. Currently, all solar power is hampered by a lack of storage capability. “The scale on which things actually have to happen on energy is not fully either appreciated or transmitted to the public,” said Dr. Lewis of Caltech. “You have to find a really cheap way to capture that light, for the price of carpet or paint, and also convert it efficiently into something humans can use for energy.”
