I Like to Move It: Cell Phones That Charge Kinetically

Environmentally friendly charging options for cell phones have been kicking around for a while now, from solar-powered chargers to phones with built-in solar panels. But if you check out the ModeLabs website, you'll see something different: three concept phones designed to capture energy from actually using the phone. (It's the same concept as hybrid cars that use the stop-and-start of city driving to capture energy.)

The three phones are the YoYo, U-Turn (pictured) and Runaway, all of which work with motions associated with the type of phone. It's unclear how the the YoYo (which also uses solar energy) works, but the U-Turn captures energy from the action of opening and closing it, while the Runaway, designed for more physically active users, gets it juice from the motions associated with exercise.
