Are we closing in on laptops that can recharge without those annoying power cords? Yesterday Intel, the world's largest chip manufacturer, demonstrated a form of wireless energy transfer by lighting a 60-watt bulb from a power source three feet away, in an effect they referred to as WREL (wireless resonant energy link). If the trick sounds familiar, that's because researchers from the Massachusetts Institute of Technology (MIT) reported the same thing last year under the moniker WiTricity. Two years ago, MIT researcher Marin Soljacic figured out a way to transmit electricity via the magnetic field surrounding a charged loop of wire. A similar loop wired up to a light bulb or another electrical device would draw power from that magnetic fieldno wires attached. Soljacic and his colleagues reported a year later in Science they could transfer energy to a 60-watt bulb with 50 percent efficiency from six feet away and 90 percent efficiency from three feet. Intel announced they had achieved 75 percent efficiency from two to three feet away. An Intel researcher contacted the MIT group with some technical questions after the study came out, says Andre Kurs, an MIT PhD candidate and first author on the Science paper.
Note: Yet no mention is made of the fact that genius inventor Nikola Tesla may have developed wireless electricity over a century ago. Click here for information on this. Some claim Tesla was largely written out of history books because he threatened the establishment with the possibility of nearly free electricity for all people. For more on this, click here.
