Intel Shows Wireless Resonant Energy Link at IDF
Intel recently demonstrated wireless power transmission at the Intel Developer Forum (IDF). They call it "Wireless Resonant Energy Link" (WREL), and it is based on principles proposed by MIT physicists (Marin Soljačić & others). Intel CTO Justin Rattner showed such a system lighting a 60 watt lightbulb on stage (too bad it wasn't a CFL -- they could have used 3). In 2007 MIT researchers had a prototype working at 40% efficiency, and now Intel claims that 75% is possible.
