If you’re looking for the perfect gift for the techie in your life, look no further. Regen, a company that specializes in making solar-powered gadgets, most notably of which is their ReNu which powers any of their other devices such as the iPod Dock, Audio Dock, and Side Light.

But the most recent addition to the Regen family of solar gadgets is the ReVerb, a high-quality speaker with an integrated photovoltaic solar panel that generates enough energy to power the speaker for up to 12 hours at normal volume (to get it fully charged takes about 20 hours). Simply plug in your iPod Touch or iPhone to access digitally-stored media files and away you go.  It also comes equipped with 2x USB ports, 1x USB input for charging the unit, as well as a nice little LCD display (about four inches).

Though the speaker can also be powered by a regular AC adapter, it is meant to be run with solar power. And it provides some very nice quality sound, according to reviews. The Earthtechling reports that:

“It generates sound equal to that of a regular 60-watt speaker and sports stereo drivers and a sub-woofer.”

You can also use the speaker to control your audio device, whether you want to play/pause, increase/decrease volume, or select a different track. And one of the best parts is that it actually gives you feedback about how you’re using it. For instance, if you’re running low on power because of a lengthy playback session, it’ll let you know that it’s dissatisfied by displaying an unhappy face. Now that’s a full-service speaker!

But it doesn’t come cheap: about $2,300 each! And they won’t be available until April 2010.
