Victor Vetterlein designed this slick prototype speaker dock to power iPods. The speaker base has rechargeable batteries that can power the stereo system for hours.
Vetterlein plans to make the dock capable of using a renewable energy source such as solar power, wind power, or hydroelectricity to charge the battery packs when the stereo is not in use. Each speaker is wireless and can be removed from the base unit.
Though this would look great in a living room, the rods between the speakers act as handles so you can carry the YO out for al fresco entertainment.
