I love my laptop. No matter where I go, I can take it with me and have basically my entire life at my fingertips. That kind of freedom just feels good, ya know? Of course, until you have to plug it in to recharge. Then, you’re tethered to the world like everyone else. Well, the folks at MIT’s Department of Physics, Department of Electrical Engineering and Computer Science are trying to do away with that. In what they call "WiTricity," they’ve taken their theory and applied it to a light bulb…which they were able to light up from a power source 7 feet away. No wires. No connection. Yes, at this point, it’s like the guy who invented the square wheel, but there’s progress, people!
