...Reader is about the size of a trade paperback, though thinner, and instead of a liquid-crystal display, its 6-in. screen uses E-Ink technology. Each of its finely packed pixels can be white or black but they don't shimmer or emit any light, so the experience is eerily like looking at paper, high in contrast and relaxing on the eye. The tradeoff is that E-Ink can't yet refresh fast enough to show video, and even scrolling or zooming is a complicated business, but that's not the purpose of the Reader. Even without a backlight...
...tackled at the supermarket and the source [Sept. 11]. Whole Foods, Safeway and Wild Oats have voluntarily posted government warnings about mercury in fish. But other companies should follow suit and let customers know which fish contain high levels of mercury. Few people are aware that chlorine plants emit more mercury on average than coal-fired power plants. Technology to eliminate mercury in chlorine processes is already used by 90% of the industry, but six plants still use and release mercury unnecessarily. Mercury release could be cut substantially if they too would shift...
...average listener, Bush’s words sounded reasonable. The exhaust from a hydrogen engine is just plain water—unlike the noxious mixture of greenhouse gases, acid rain-causing compounds, and uncombusted gasoline that normal engines emit. And supporters hope that increased usage of hydrogen would alleviate our dependence on foreign oil, if we aren’t fuelling up with Saudi gas. This is the popular allure of hydrogen fuel: cleaner than Dick Cheney’s dinner plate, and not beholden to unstable and perhaps unfriendly governments...
...challenge, then, for creating cars that run on something other than oil—and, further down the road, generating the bulk of our electricity from something other than coal—is two-fold. We need a renewable energy source that doesn’t emit greenhouse gases. And we need a way of storing that energy in a form that can be driven around. The latter has few viable solutions: despite intense research, battery technology is still relatively poor, and hydrogen has all the disadvantages already discussed. For the former, we have lots of promising, but highly underdeveloped...
...Still, few doubt that the task is daunting. No one is even certain how much greenhouse gas every industrial plant emits, since the federal government has hitherto fought off lawsuits to force the regulation of carbon dioxide as a pollutant under the Clean Air Act. That issue will be argued before the U.S. Supreme Court next December. But regardless of the outcome, California's new law, which was adopted by the legislature Thursday and is expected to be signed by Schwarzenegger next week, would require that its industries measure exactly how much they emit by 2008. Then...
