Wireless charging or Cords, a thing of the past?

 Wireless Power, What is it? This summer, Intel researchers demonstrated a method--based on MIT research--for throwing electricity a distance of a few feet, without wires and without any dangers to bystanders (well, none that they know about yet). Intel calls the technology a "wireless resonant energy link," and it works by sending a specific, 10-MHz signal through a coil of wire; a similar, nearby coil of wire resonates in tune with the frequency, causing electrons to flow through that coil too. Though the design is primitive, it can light up a 60-watt bulb with 70 percent efficiency.

When is it coming? 

A year or two from now you'll also be able to purchase laptops, tablets, mobile phones and other consumer electronic devices that don't need any wires, because their power needs will be met by wireless transmission.

"Instead of having a different charging cord for every device you own, you can have one location where you put your mobile phone or your laptop, and it will stay charged automatically, says Morris Kesler, chief technology officer at WiTricity of Watertown, Mass. "There is no reason that these devices need a cord anymore.

WiTricity, an MIT spinoff, offers highly resonant wireless power transfer technology that "is applicable in any situation where a device has a cord or a battery that needs to be charged,” Kesler says. It doesn't take much imagination to envision the benefits of not having to pack up those bulky AC bricks and yards of cords into your carry case each time you hit the commute trail to work and home again. Consider not having to worry about trading off computer performance for battery life. When, not if, this technology becomes mainstream, planes, trains and automobiles can all be retrofitted with wireless charging so while you passing the time your laptop is topping off its battery or you are finishing up work on the train ride home that would have had to wait for an AC outlet. Finally, an answer to the issue of what do you want more, computer performance or battery life, why not both?
