If you think that there is no idea to turn everything including your Sound system into a solar powered device, than you are wrong. Now designer Paolo Metaldi and Luca Elli has a bright idea about an Sound System concept that comes with a photovoltaic panels at the top part to grab Sun’s energy to power up the speaker.
This is not an impossible concept for nowadays technology. It only need a certain resourceful company to make them into a real stuff.
Now if this concept materialized, it could be a good Outdoor speaker system and it could be better if they can equip a wireless technology to their concept. It will make it the best outdoor speaker for Summer vacation, or the best patio sound entertainment for those who love to roam there reading books.
