thoughts on the drought going on in the western part of the U.S.

In the western part of the U.S. there has been a drought going on for the last few years with no real change in the foreseeable future by meteorologists.

The question is what do the municipalities and companies going to do about the need for water versus the lack of available drinkable water.

I think that each U.S. state that has coastline should be desalinating water with the states closest to the drought stricken areas of the country doing the most desalinating given the increased need for water.

Yes desalinating sea water is expensive but what I'd like to see happen is that the water itself be directed on the intake end in such a way that would help create as much of the energy needed as possible.  Where we use dams in rivers to create reservoirs and to create energy, why cant we design large scale holding tanks that permit intake from the tides and by a siphon with the intake having water turbines that can be powered by both the siphon and the high tide?

Where there are water turbines that work with the ocean currents and a siphon creates a man made current in a tube, why can't they be adapted to be used with a siphoning effect for the intake of ocean water for a water desalination plant to help create the needed energy?

Why can't we use the facade and roofs of the buildings that would be a part of the desalination process to house solar panels facing the path of the sun?

Given the advances in windmill technologies why can't we have rooftop windmills on the property or rooftop windmill type windmills in strategically placed areas between buildings to catch the wind as it goes around the buildings where the space between buildings can act like a wind tunnel.

The cost of desalinating water is expensive but what are the economic and environmental costs of not doing as much large scale water desalination as possible in the areas where we have millions of people and countless farms that would be hurt or helped by doing or not doing desalination?

If we started doing a lot more large scale desalination we would create badly needed jobs for every step along the way from building to running the plants.
