Charge your lingerie while you make the move

The world is going green. There are varied devices flooding the markets that convert energy from different sources from motion. One of them is the charging Bra. The concept is simple, jump to generate energy and charge your phone or iPod or whatever is chargeable. It would probably be made of elastic so that it gets even more motion. That's great for onlookers and energy.

A small piston could even be used to get more juice. Sure, there are a bunch of obstacles to overcome, but I think it's a worthy endeavor as we strive for more energy.I just wonder how in public are you going to re-charge your dying battery.
