Eco Gadgets: Solar-powered speaker brings sustainable music to your tabletop
Eco Factor: Concept speakers powered by solar energy.
Designed by Pekka Salokannel, the Gramo Speakers are just what you need to green your musical life. The speakers are powered by three layers of photovoltaic panels that are incorporated onto their surface. The solar panels charge the built-in battery pack, allowing the user to use the speakers even after sunset.
If you want some digital entertainment when outdoors, the speakers can be bent flat and carried in a pocket. The volume can be adjusted using the soft touch-sensitive control that the speaker is equipped with. The Gramo is designed to be compatible with most DAPs, including the iPod and iPhone.
