Intel demos a Wireless Power system
Intel shows off a new wireless power broadcaster
These things have been tried before, but this technology has got to make an entrance into the market in the near future, if only to charge small devices like mobile phones. Efficiency is always a problem though, however Intel claim to get 75% efficiency, which is pretty impressive, although you can see the argument from the green side of things, thats 25% power wasted just because people are too lazy to use a cable! I personally think however that this technology should be researched and played with, as it is very very cool.
