Jinsic Kim has designed these Sunbox solar panels, which can be hung outside on a clothesline in the sun alongside your laundry. Sunbox is a very simple and lightweight device; it only consists of an electric connector, an insulator hook and two pieces of solar mirror.

The portability of Sunbox solar panels means that you can charge these eco batteries with ease. This is definitely one eco design we'd love to see go to market.
