I don't know the details of this particular desalination plant concept, and perhaps it is flawed, BUT the climate forecast for California for the future decades is to become hotter and drier, and the reduced Sierra snowpack and groundwater will no longer be sufficient for our water needs in this area - possibly within as little as 20 years. It is highly likely that the ONLY reliable source of water in the future will be desalinated ocean water. We should be cognizant of this forecast, and not dismiss desalination development out of hand. Hopefully we'll find ways to use renewable energy sources and limit the impact on the environment by the time desalination becomes necessary.
