Twirling cell phone battery

    A lot of times, we are stuck out in public without our phone chargers handy. This leaves us vulnerable especially when we need to make an important call.
    This idea about a twirling battery is really cool. The concept is to simply twirl the cell phone battery around a finger a few times for a quick bit of juice to send a text or make a call. 130 twirls will give you approximately two minutes of talking time.
    The same idea could also be applied to batteries for other devices.

Kinetic batteries (edit | delete)
Why not Kinetic, like the watches that recharge simply from the movements you make. This is an awesome idea, of course, it would cut out profits from all the cell phone chargers we have to buy, house, car, etc, lol.
