By the way Mike - I totally agree with desalination plants. They should have been built decades ago.
Interesting...Of course you DO understand that desalinization *IS* Reverse Osmosis...?
I know but here in California we're experiencing the worst drought in 100 years! We need more fresh water every year.
Also, like Mike said in an earlier post, much of California is a natural desert which needs a zillion gallons of water. Because of the weather California grows massive amounts of food for the world but it needs water ... which without getting political is too often diverted for other uses ...
