The 2010 Expo in Shanghai is proving itself to be more and more earth-friendly. First with the Canadian pavilion’s green wall, now the Swiss pavilion, which will not only have a green roof, but soybean and sun cell walls.

The Swiss pavilion design looks made from earth. From the roof to the soybean walls which, incredibly enough actually harness sun energy which is then used in the building, the design is as eco-friendly as one could ask for. Take a look at the great soybean design.
