This is really cool. William McDonough is shown in the small video below describing the design for a true eco city in China. Although he has a pretty flat and dry delivery, the 3:20 second video is worth watching. There is so much that can be done in development if we are only willing to think outside the box. The before and after photo of the proposed city site is amazing and absolutely gives me hope for what is possible.
Check out the video here and see what I mean. Consider some of the topics as possibilities for your own home, obviously on a smaller scale. There is much to consider here.
