California has water that is next to free from the snowpacks.  Water is so cheap that desalinated water, which costs about $0.45&#x2F;1000 liters, is almost never seriously considered a major source of water (as compared to places like Dubai, or even Singapore, where it is a major source of water) - even given that vast portions of the population live <i>right beside the ocean.</i><p>Several iterations of this device might result in something very useful in areas far away from the ocean (which makes desalination difference), and lacking the major infrastructure for centralized water recycling.
