...Talk about back to the future: Coal, the miracle fossil fuel that jumpstarted the industrial age, but has been viewed in recent decades as backwards and dirty, is hot once again. Technology and economics may be aligning to make the black rock more useful and economically efficient than ever. And guess what: the U.S. has more of it than any place else-27 percent of the world's total. Coal-burning power plants fuel half of the nation's electricity. That was true even during the 1990s, when utilities built plants that burn cleaner natural gas. Back then, natural...
...engine stops when idle and the electric motor boosts acceleration, but unlike full hybrids (such as Toyota's Prius), this vehicle can't run on the electric motor alone. The mibrid is cheaper to make and has a small battery, which lightens the load. And diesel makes it more fuel efficient than a regular gasoline hybrid. Mercedes' parent company, DaimlerChrysler, says that its diesel hybrid is 10% to 15% more fuel efficient than a full gasoline hybrid. The company says it is "close to market" with the new vehicle. BMW is closer. The Bavarian company says it plans to introduce...
...owned by the French state, is a one-stop shop for nuclear energy with almost a one-third share of the market. Unlike its key competitors Westinghouse and General Electric, its activities span all aspects of the business: it mines and enriches uranium ore to make nuclear fuel; designs and constructs reactors and helps to operate them; it also recycles the spent fuel and packages the remaining waste. Just last month, it announced a joint venture with Baltimore-based Constellation Energy to promote its new generation of nuclear plant in the U.S. and expects orders for four reactors once...
...three energy sources--gasoline, electricity and hydrogen. The main combustion engine can burn either gasoline or hydrogen, which is fed to the engine from a tank in the trunk. The driver can change between the two by hitting a switch next to the steering wheel. Hydrogen as a fuel burns like gasoline, but it's about 10% more efficient, and emits only water. Throw in the hybrid function (an electric motor) and fuel efficiency rises again. Mazda hopes to have the car available in three years. In the meantime, Mazda plans to introduce a duel-fuel RX-8 sports...
...suggesting Kim and his minions have turned nice. Just more pragmatic. Their economy has shrunk an estimated 30% in the past five years, and persistent food shortages are threatening to turn into famine. Even their prized armed forces are deteriorating for lack of food, fuel and modernization. U.S. defense strategy is anchored on preparations to fight two major regional conflicts at almost the same time, and the Pentagon has long counted North Korea as one of the two. But that contingency may be fading. The North's leaders are now showing they are interested in survival, not destruction...
