...oxygen, then heats it at a high temperature - around 1,830 degrees Fahrenheit - in an air-tight chamber. The resulting syngas - a cocktail of light gases, including methane and natural gas - is burned, boiling water into steam to run a turbine. Gasification is an established technique, already used with fossil fuels, particularly coal. Applying it to rubbish opens a new and abundant fuel source. "As a waste-disposal method, it seems to make a lot of sense," says Jonathan R. Gibbins, an energy expert at London's Imperial College...
...island's carbon footprint. It will emit the about the same amount of greenhouse gases into the atmosphere as does decay from the landfill. "The benefit is, we're producing electricity" from a renewable source, Grimshaw says. Because those 2,000 homes won't be getting power from a fossil fuel plant, Energos estimates that will cut carbon emissions by 2,000 tons...
...least. There's no question that a nuclear plant, once it's up and running, produces comparatively little carbon dioxide - a British government report last year found that a nuclear plant emits just 2% to 6% of the CO2 per kilowatt-hour as natural gas, the cleanest fossil fuel - but nuclear energy still seems like the power of yesterday. After a burst of construction between the 1950s and late 1970s, a new nuclear power plant hasn't come on line in the U.S. since 1996, and some nations like Germany are looking to phase out existing atomic plants. That reverse...
Then came Obama in St. Paul, Minn., with his wife Michelle next to him in a violet sheath (purple = red + blue). After a carefully gracious tribute to Clinton, he went right at McCain for being a quaint fossil of the Paleolithic era before launching the race into deep space. "This is our moment," he said. "This is our time." Moments, of course, are fleeting, and he talked about this one in the way geologists talk about eons. "Generations from now, we will be able to look back and tell our children that this was the moment ... when the rise...
...world of increasingly constrained fossil fuel supplies, the only way to achieve lower prices will be through new policy that promotes the development of alternative energy - like cap and trade. But figuring out how to assemble a political coalition that understands the argument and shows deep support for climate change action - that will be the real challenge, long after Warner-Lieberman has been sent to the legislative graveyard...
