...there any replacement for long-haul air travel itself. I can take a train from Boston to Washington, but until we can figure out how to travel via fireplace, Harry Potter--style, the only way I'm getting from Tokyo to New York City is in aircraft that may emit more than 5,200 lbs. (about 2,400 kg) of carbon per passenger, round-trip, according to one estimate. On an individual level, you can try to make your flight carbon neutral by donating to, say, a forestry project that will soak up the greenhouse gases you have created...
...easy to mock His Royal Highness; in England it's practically the national sport. But his critics may be onto something. Jets are uniquely polluting, and the carbon they emit at high altitudes appears to have a greater warming effect than the same amount of carbon released on the ground by cars or factories. On an individual level, a single long-haul flight can emit more carbon per passenger than months of SUV driving. Though air travel is responsible for only 1.6% of total greenhouse gas emissions, according to one estimate, in many countries it's the fastest-growing single...
This eyewear, developed by M.I.T.'s Media Laboratory, has a tiny name-storage device that picks up the identification signal cell phones emit and then searches its database to see if a name matches. A miniprojector on the stem flashes the name of the friend or relative encountered on the glass lens for one two-hundredth of a second--so fast it isn't noticeable, yet lab tests have shown the subliminal prompt is enough to improve name recall by 50%. In the prototype, wearers must carry a battery wired to the glasses, but eventually a wireless system will...
...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...
