Submission + - MIT Research Team Develops Model for Wireless Powe
Giuliano writes: "The idea of wireless energy transfer has been around for a number of years, but now MIT believes it can be done inside the lab Massachusetts Institute of Technology (MIT) researchers have created a system that is theoretically able to power electronic devices wirelessly. Assistant Professor Marin Soljacic of the Department of Physics and Research Laboratory of Electronics, along with MIT graduate students Aristeidis Karalis and John Joannopoulos, are working on the "evanescent coupling" technology. The primary downfall of other power-over-air technologies is the fact that they are extremely directional or extremely dangerous. The first roadblock in wireless power is traditionally solved by simply increasing the power and using omni-directional antennas. This unfortunately gives rise to the second downfall; enough of an increase in power to make omni-directional useful traditionally results in so much energy transmitted that it is no longer safe for humans to stand near the device.
