Music lover individual that love the listen to their favorite music anywhere will definitely love to hear the green invention of Pekka Salokannel called the Gramo Speakers, a solar powered speaker. It has three layers of photovoltaic panels that collects the sun power and charges the built-in battery pack so that users can still enjoy the freedom of music even when the sun sets already. And not just that, the Gramo Speakers can also be enjoyed anywhere because it can easily bent flat for easy transport. One more thing, this eco-friendly speaker is compatible with different portable players, which includes the iPod and iPhone. I cannot wait seeing this product available in our place soon.
