I can’t say it enough: The Economist’s iPad app is my favorite digital reading experience. It manages to be pleasurable, informative, and easy on the eyes at the same time. There is no sacrifice in the reading experience and makes the transition from paper to screen nearly seamless. Kudos!
“A breakthrough in oil cleanup technology allows crews to skim spilled oil off the water’s surface at a much faster rate. The new device wasn’t developed by Exxon, BP or any of the major oil companies — it’s the work of Elastec/American Marine, based in Illinois. And the design won the company a rich prize from the X Prize Foundation.
Oil is attracted to plastic. And water is not. That, in essence, is the basis of Elastec’s new skimmer.
It’s huge, about the size of a large U-Haul truck. And it looks something like a giant abacus. It has 64 grooved plastic discs, arranged in rows, with a scraper along the top.”
