Found this great article on Technology Review about a team of researchers that have found a way to power a light bulb without wires, and one day this technology could recharge cellphones and other devices wirelessly as well.
Probably one of the coolest inventions I have seen this year and is no doubt worthy of a Nobel prize in my personal opinion. Of course I always love to hear what others think what this type of technology could be used for so do so in the comments.
