The water catchment system on my property.
The humble puna water tank was in the news, recently, and got some of the credit it deserved.
Many consider it an inconvenience, but I actually prefer it! It is "green"(mine is really green) it helps the property owner to be independent, it prevents some erosion, and obviously conserves water.
Come to Hawaii, and you can build a home out of recycled materials, grow a garden all year round, plant an orchard, and eat fruit all year round. You can go completely solar, and catch your own water! Go snorkeling in January!
