Food scraps are a recent focus for recyclers in part because, unlike glass and plastic, organic waste will decompose once it's put in the ground. But that becomes a problem in municipal landfills. As buried food breaks down in these oxygen-free environments, it produces methane, a greenhouse gas that has a warming effect 23 times as potent as carbon dioxide. Global methane emissions from garbage are estimated to be as high as 70 million metric tons a year. By recycling organic waste--composting it--methane emissions are eliminated...
...Gasification mixes waste with small amounts of 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...
David Mamet has me in a rear naked choke hold, and I'm quickly losing oxygen. He has knocked me to the ground and spun me on my back, with his right arm hooked tightly around my neck. He is 24 years older than I am and quite a bit shorter, but it has been determined in less than 20 seconds that he can kick my ass. "That was very good," he says, his breathing only faintly increased as I get up from the mat and suck in air. "You moved it from a double-leg takedown to a single...
...Venetian island famed for its glassware. The three decanters boast an avian grace: the Swan's swooping body, the Flamingo's long slender neck and the Paloma's dove-like curves. And as with any Riedel product, they are masterpieces of function as well as form. Exposing wine to oxygen for a few hours before pouring can improve its taste (thanks to a chemical reaction known as aeration), so each of the $480 decanters has been shaped to maximize a wine's contact with the air as you empty the bottle into...
...With or without pure oxygen, holding your breath is a difficult and dangerous pastime even for elite athletes. When not done carefully, it can lead to drowning, or to potential tissue damage in the heart, brains or lungs. Preliminary results from Potkin's research into apnea's long-term effects show some abnormal brain scans among young, extreme free divers. There's still much to learn about the phenomenon; as a medical student, Potkin recalls, he was told that no one could hold his breath for more than five minutes without suffering brain damage. Now, he wants...
