http://www.gizmag.com It's fascinating to think that while Edison and Tesla battled over the ascendancy of AC versus DC, most of the world didn't think this electricity thing was going to take off - I mean, who was going to spend trillions of dollars rolling out great coils of copper wire to bring this thing to the masses? Nikola Tesla was thinking along the same lines, and the Serbian genius's mysterious Wardenclyffe Tower was to be an experiment in beaming electricity wirelessly across the world, eliminating the need for a wired power grid altogether. But wireless electricity has been enjoying a cautious revival in the past decade - mainly at short distance and for reasonably trivial applications like charging cell phones and other battery-powered equipment. And as Eric Giler's great ten-minute demonstration at this year's TEDGlobal shows, wireless power seems very close to breaking through into the mainstream market.en gizmag.com http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8689 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8689 Mon, 21 Sep 2009 15:44:06 -0500 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8281 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8281 Thu, 03 Sep 2009 17:49:47 -0500 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8257 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8257 Thu, 03 Sep 2009 01:45:15 -0500 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8221 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8221 Tue, 01 Sep 2009 12:24:58 -0500 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8215 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8215 Tue, 01 Sep 2009 09:38:43 -0500 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8209 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8209 Tue, 01 Sep 2009 09:33:23 -0500 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8203 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8203 Tue, 01 Sep 2009 08:18:33 -0500 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8194 http://www.gizmag.com/wireless-electricity-demonstration-video-ted/12655/#comment-8194 Mon, 31 Aug 2009 19:16:56 -0500
