If you've ever driven down 5 or 99 in winter, you can well imagine what a boost this would be to the drought-stricken Central Valley, not to mention the coastal areas!

... Developed over the past 5 years on the Canary Islands by Hernando Theo Olmo and Ricardo Gil, the Water Gardens are groupings of water-extracting towers for high volume and high quality water. Some of the planned uses are for forests, camping, fire suppression, agriculture, livestock, and human consumption.
According to the website; After years of experimentation and improvement, our NRP 3.0 fog collectors are currently the most technically advanced and productive in the world in the last 50 years in this sector, with a maximum collection of 1,074 liters / day and a life of more than 10 years.
The NRP 3.0 fog collector, have a huge collecting surface of 56 m2 into minimum space, only 1.6 m2, thus reducing the area occupied by 90% and minimizing the visual impact. Its three-dimensional structure gives great stability and prevents the loss of water out of the structure and also minimizes the influence of the wind direction in production of water. It also has a base designed to decant and filter the water before it passes to the tube system....
Due to the rate cost-production, this system allows us to consider definitely the mists as another water resource, complementary to the existing resources, and this, in a practical, cost-effective, sustainable and innovative. Water from the mist can be used for qualitative and quantitative improvement of the waters from another origin, which can also help to reduce transportation costs, pumping or treatment of these, saving energy and minimizing pollution.
