Growing and burning many biofuels may actually raise rather than lower greenhouse gas emissions, a new study led by Nobel prize-winning chemist Paul Crutzen has shown. The findings come in the wake of a recent OECD report, which warned nations not to rush headlong into growing energy crops because they cause food shortages and damage biodiversity. Crutzen and colleagues have calculated that growing some of the most commonly used biofuel crops releases around twice the amount of the potent greenhouse gas nitrous oxide (N2O) than previously thought - wiping out any benefits from not using fossil fuels and, worse,...

By Peter Hoy, September 18, 2007 Interested in an energy-efficient auto? You're in luck. That's because nearly every major car company has a hybrid line, or has plans to introduce one soon. But enter the showroom, and instead of seeing green, you may be seeing red. Many of the market's hybrids--cars which combine gasoline engines with battery-powered electric motors--forsake fuel-efficiency in the name of power and performance. The average gas mileage of hybrid models available in the U.S. is 33 miles per gallon (combined city and highway). Read more about "<i>Forbes</i>: Electric hybrids not always energy efficient"...
BOSTON (Reuters) - A U.S. District Court in Vermont today upheld a state law that calls for a 30 percent reduction in the amount of carbon dioxide, a greenhouse gas, emitted by cars and certain light trucks. In his decision, U.S. District Judge William K. Sessions found that the Vermont law -- which regulates greenhouse gas emissions -- did not conflict with federal regulations on fuel economy. "The plaintiffs failed to prove the regulations were preempted," Sessions wrote in his decision. Automakers General Motors and DaimlerChrysler AG -- which has since sold its Chrysler unit -- sued in 2005 to... Read more about "US Court upholds tough Vermont auto emissions law"...
Engineers commonly ask how the Scuderi Engine deals with heat, particularly in the engine's power cylinder. In this interview, Scuderi Group President Sal Scuderi answers the thermal question. As Sal points out, the Scuderi Engine actually has lower peak temperatures than a conventional combustion engine, and the company's research indicates that no special materials or lubricants (beyond commercially available synthentic oil) are required in the design.
