...high-speed” Acela can only travel an average of 85 miles per hour. Meanwhile, on the other side of the world, a close friend of mine from high school was landing at Shanghai Pudong Airport for his semester abroad. He bought a ticket for the brand-new Maglev train from Pudong to the center of the city, covering a distance of twenty miles in seven minutes...
...maglev takes a load of hardware and a ton of power and is useless for small, simple kinds of engineering. The new breakthrough - achieved by a joint team of researchers from the National Institutes of Health (NIH) and Harvard University and published in a paper in the journal Nature - provides an alternative...
...efficiently and for a far longer time than they otherwise would. When the metals are magnetized, they become so powerful that their ability to repel one another can actually allow them to lift heavy objects off the ground. That's the elegant principle behind some kinds of magnetically levitated (maglev) trains. (See the 50 best inventions...
...June, authorities blocked access to an online video apparently showing drunk police officers in Henan province beating up a college girl that had been posted to several major video-sharing websites. And this week, mobile phone videos showing hundreds of people protesting against a proposed extension of Shanghai's maglev train line have appeared on YouTube as well as on mainland web portal Sina.com...
...sort that could reduce greenhouse gas output far beyond today’s optimistic projections. One such technology is the magnetic levitation wind turbine, a colossal rotating structure that uses magnetic levitation to minimize friction and reduce inefficiency—the same principle that allows maglev trains to travel at very high speeds. The technology was debuted in a 2006 energy conference in Beijing, but is now being pushed in America as an alternative to expansive wind farms. The companies building magnetic levitation wind turbines claim they can operate in winds as slow as 3 mph and produce one gigawatt...
