Cities.. Engineers are working on new ways of creating the self sustainable city but what are the possibilities? The Dutch Windmill concept is one of those great architectural inventions when it comes to sustainability. However, what I recently came across amazed me quite. Have you ever thought about the amount of glass we need to build our cities. Al those windows. Some skyscrapers exteriors are almost made entirely out of glass. Would it be awesome if we could harvest all the solar energy through our windows? Maybe soon we can!
