The Regen Renu is one impressive solar powered iPod dock, but the Regen Reverb is all the more.

Granted, it is no Wall of Sound, but it is three feet tall and does 60 watts worth of power. It takes 20 hours worth of the sun’s rays to give it a full charge at full volume, and 12 hours at normal volume. It does cost a pretty penny at $2,229.
