Solar-Powered Speakers Make For Less Guilt, More Boogie

Pekka Salokannel's Gramo Speaker concept is an eco -- and aural -- treat.

They've been specifically designed for a digital music lifestyle. They can cozy up to your laptop, transform into a tabletop speaker, or be taken on a picnic along with your iPod. Oh yeah, and they're powered completely by three layers of photovoltaic panels!

And for any nocturnal booty-shaking you might have planned, the solar panels charge an internal battery pack . But it's their portability that's the real win. The speakers can completely unfold so they are flat enough to carry around in your pocket.

Both its design and name were inspired the gramophone, a device that makes the 8-track look like an iPod. But the similarities end there.

Of course this isn't the first time we've seen eco-friendly speakers, or even the first ultra portable set. But Gramo's are more than just paper cups and string!

But if the Gramo isn't your thing, there's always this option.
