  • Happens in most cities of the world. Rainwater is seen as a problem, not a resource, yet we use drinking-quality water to flush our toilets and do our washing. Then we wonder why we have shortages. Both industry and home users could cut their water burden on the infrastructure by a fraction just by using what's around us. The same is true of energy; I think the future of our technology will need to rely on distributed use and production, rather than centralised generation and control.

  • I saw a documentary on how they could build a system of cisterns & collect rain water in Los Angeles & supplie over 1/2 of their water needs if they were willing to do it. Sad to think they take the water from 200 miles away & let what falls on LA go down the drain.
