"We both shift our gaze to an unplugged Toshiba television set sitting five feet away on a folding table. He's got to be kidding: There is no power cord attached to it. It's off. Dark. Silent. 'You ready?' he asks. If Soljacic is correct – if his free-range electrons can power up this untethered TV from across a room – he will have performed a feat of physics so subtle and so profound it could change the world. It could also make him a billionaire. I hold my breath and cover my crotch. Soljacic flips the switch." [via Fast Company]

CES: Video projector comes to your cellphone
"Sure you can watch videos on some cellphones, but the picture is so tiny. Now comes a solution. At CES, Samsung and Texas Instruments debuted the first cellphone with a tiny video projector hidden inside that can shine whatever is on the screen onto a wall, the back of a notebook or even a friend's shirt."
