World's First Road-Powered Electric Vehicle Network Opens
Daniel_Stuckey writes "South Korea continues to pull out all the stops on the long road to a high-tech utopia. Last year, the city Yeosu hosted the Expo 2012, an international exhibition that highlighted emerging technology and design that attracted 8 million visitors over three months. Today, the nation has finally unveiled the world's first road-powered electric vehicle network for regular use. Here's how it works: the network runs on newly-built roads that have electric cables and wires embedded below the surface. This allows for the magnetic-resonance transfer of energy to the network's vehicles, which not only already run on small batteries (about a third of the size of a typical electric vehicle) but also do not require the plug-in-and-recharge process common to other electric cars."
Don't worry, the problem of people trying to charge their mobile devices in the middle of the road will solve itself fairly quickly.
Any sufficiently unpopular but cohesive argument is indistinguishable from trolling.
I would presume that while the field is quite robust, that the rate of alternation will be either absurdly fast, or very slow.
RTFA - or at least look at the pictures (it's in the caption of one): Feed to the coils in the road is 20 kHz, 200A.
Bantam Dominique roosters crow a four-note song. Once you've heard it as "Happy BIRTHday" you can't NOT hear it that way
