This post, while not specifically discussing architecture deals with the technology that we can put in our buildings. Indeed, this idea has enormous potential, and I am sure we will be seeing this or other similar technology in our buildings/homes in the near future. As you will see in this CNN video, I guess it just took 20 plus years to realize that maybe we could save a lot of water and resources by just trying out the the same space shower technology which lets space station astronauts take showers for years with a very limited water supply.
