NTT is developing a high-tech shoe that charges your MP3 player or cell phone. Lightweight but how does it work? Every step you take exerts pressure on a single fluid, creating water flow enough to put some oomph in a small turbine generator. Result? 1.2 watts of good ol 'electric juice to power until the iPod. Nice one.
NTT wants to pump up the power of 3W before marketing in 2010. Judging from the picture, but it is also necessary to seriously consider hiring a designer shoes.
