...parts of northern China were also affected by the brutal conditions, with residents cautioned to stay indoors. Farther south, air-pollution indexes in Hong Kong and Taiwan reached record levels. While sandstorms are not uncommon in China because of Asia's large interior deserts, growing desertification has exacerbated the problem...
...living room. (Updating Chekhov: If the author of a climate-change novel shows you a polar-bear rug in the first act, you can be sure it will bare its teeth in the next one.) Quite suddenly, Beard discovers what he believes is the solution to the problem of climate change: artificial photosynthesis, harnessing sunlight to split water and yield hydrogen and oxygen, which can be used to drive fuel cells and provide cheap, clean electricity. The earth will be saved, as will Beard's flagging career (and bank account). An unrepentant narcissist at heart, Beard has no trouble transitioning...
...home to 1.5 million people. A public-works project worthy of Kubla Khan's "stately pleasure-dome," Kangbashi is filled with office towers, administrative centers, government buildings, museums, theaters and sports fields - not to mention acre on acre of subdivisions overflowing with middle-class duplexes and bungalows. The only problem: the district was originally designed to house, support and entertain 1 million people, yet hardly anyone lives there. Only a handful of cars drive down Kangbashi's multilane highways, a few government offices are open during the day and an occasional pedestrian, appearing like a hallucination, can be seen trudging...
...life cycle. The battery has to absorb energy from braking and provide short bursts of power for acceleration. Lithium-ion batteries, with their high density-to-weight ratio, provide the greatest acceleration and range with the fewest batteries compared with lead-acid or nickel-metal-hydride batteries. One big problem: they can overheat and even blow up - bad enough in a single-battery laptop but potentially disastrous in a multibattery electric car. So engineers have been busy resolving the heat problem and refining the batteries' ability to handle partial charge-discharge cycles...
...Students often complain that they don’t acquire interviewing skills during their time in college,” Kaiser wrote in an e-mail. “We’re trying to address that problem...
