cars....sustainable design?

I was flying home from Scottsdale tonight after my wonderful visit me Steffy Fay (more to come on another post). But I happen to pick up a "Dwell" magazine at the stand on my way to boarding the flight home. I always feel creatively inspired when I read this modern home mag. There was a fascinating article on the german architect Werner Sobek. The article discussed Sobek's desire to make sustainable design through architecture by using recyclable products. He explained in Germany, law requires automakers to produce care whose component parts are recyclable and he decided that he wanted to do the same in the building industry. I thought this was interesting because i just bought a german car.
