...heading for a collision with states and cities struggling to meet pollution standards. Environmental controls on electric plants have cut emissions of six principal air pollutants by half since 1970, despite a 42% increase in energy consumption. But even with mandated controls, old-fashioned pulverized- coal plants still spew nitrogen oxide and sulfur dioxide (think acid rain) as well as toxic mercury. Carbon dioxide emissions, blamed for global warming, would soar. Shareholder activists are increasingly aggressive about demanding an accounting when companies like TXU, which had 2005 earnings of $1.7 billion, stick to old coal methods. "TXU," says Leslie Lowe...
...granddaddy of coal plants, Big Brown, built in the early 1970s in the rolling hills of east Texas, the sky is a pristine blue above two big smokestacks. That's illusory, since the plant pumps out a steady stream of can't-see-'em pollutants like nitrogen oxide, sulfur dioxide and mercury. Inside, giant HEPA filters (which look just like a nest of vacuum bags) grab most of the solids from the coal fire. You wouldn't want to eat off the floor, but the place is clean. Even the open-pit-mining operation nearby--which has scoured...
...filthy!" from the TXU staff. "They don't see the irony," she says. "'Why would you want to touch the coal?' they asked. My response? 'Why would I want to breathe it?'" TXU estimates the plant emits 82,000 tons of sulfur dioxide, 6,700 tons of nitrogen oxide and 1,180 lbs. of mercury a year--not to mention 10 million tons of unregulated carbon dioxide. Now it wants to add a third smokestack...
...Gastrovac and plating it with a caper and red pepper broth. "It has the same sheen as it did when it was raw!" Call it the Blumenthal-Adrià effect. Ever since Europe's two famously avant-garde chefs, Heston Blumenthal and Ferran Adriá, began using liquid nitrogen to freeze mousses tableside and siphons to turn squid ink into foam about five or six years ago, the walls between the laboratory and the kitchen have begun to crumble. "This is the great revolution in cooking right now: the incorporation of industrial techniques into the kitchen, and the collaboration between...
...Ages began, the cosmos was a formless sea of particles; by the time it ended, just a couple hundred million years later, the universe was alight with young stars gathered into nascent galaxies. It was during the Dark Ages that the chemical elements we know so well--carbon, oxygen, nitrogen and most of the rest--were first forged out of primordial hydrogen and helium. And it was during this time that the great structures of the modern universe--superclusters of thousands of galaxies stretching across millions of light-years--began to assemble...
