...Global-warming concerns are driving engineers even harder. An unlikely trio of industry, the government and environmentalists wants to capture the carbon dioxide produced during combustion, the leading contributor to global warming, and store it deep underground. But that can only be accomplished-if it can be accomplished -with a gasification or liquiefaction plant. "With [current] plants there's no technology you can bolt on that really allows you to deal with that issue," says Jim Rogers, CEO of Cinergy. "We need to be building technologies that allow us to deal with...
...make us believe there are not enough data to reach a firm conclusion. But we cannot afford to wait until there is strong evidence that human activity is at least part of the problem. By then it would be too late. On the other hand, curbing our carbon dioxide and other greenhouse-gas emissions will cost very little, other than requiring some relatively small changes in our lifestyle and some economic adjustments. But if we don't make a serious effort, the consequences could be disastrous...
...applications," admits Flickinger. "But we're very optimistic about its future." Photo bioreactors already exist in labs, but because they're made from a slurry of bacteria and liquid that needs to be stirred constantly, they are inefficient and expensive. Flickinger's paint concept needs nothing more than waste carbon sources, sunshine and a thin coating of highly concentrated microbes. For the moment, more fundamental scientific and engineering studies are needed in the laboratory to prove the concept. But, one day, Flickinger's polymers could help wean us off fossil fuels, one light bulb at a time...
...water, breaking them down and capturing the hydrogen locked inside. Built on a large scale, such a hydrogen generator could provide fill-ups of hydrogen fuel for thousands of cars. The technology would also help solve a potential pollution problem by allowing a by-product of the process, carbon dioxide, to be captured and filtered at a single point. Imagine if all the pollutants could be stripped out of gasoline before you filled up your tank. Known scientifically as "unmixed steam reforming," the process used by Dupont was invented in the U.S. But she is believed to be the first...
...senate sub-committee, Max Mayfield, director of the National Hurricane Center in Miami, said, "The increased activity since 1995 is due to natural fluctuations and cycles of hurricane activity" and is "not enhanced substantially by global warming." You should have quoted him in a story about whether carbon dioxide emissions and the greenhouse effect are making hurricanes worse. John Meyer Golden, Colorado, U.S. I commend your choice of global warming as a cover story. The effects of worldwide climate change, fueled by human activity, are becoming ever more apparent. Even if it turns out that warmer temperatures do not strengthen...
