Could concentrated solar power solve our energy needs and rescue us
from the impending water shortage crisis? Check out: "http://
en.wikipedia.org/wiki/Solar_energy#Desalination_and_disinfection"
Concentrated solar power heats water to steam, moving turbines to
create electricity. This could be done with sea water to desalinize
it.
More energy and more water for consumption and agriculture?

Note that the references are to large scale systems, such as might be
undertaken by government-size entities. As a practical matter, what kind
of timeline do you envision for widespread implementation of these systems?

With a large enough installation, you can do nearly anything that might
be done with coal, gas, or nuclear power. I think you'll see as much
resistance to investment here as with the conventional options, but I'd
be glad to be shown wrong...

Yup, yup, yup. The questions are "when?" and "at what cost?" and "who's
going to make sure that the most appropriate solutions are
implemented?". Good luck on finding answers to any of these questions.
There's a tendancy to wait for someone else to produce the "magic
bullet" rather than involving oneself in producing smaller, more
managable local solutions - with the expected lack of results.

Although, the site is partially in Dutch, you can find a lot of information
about CSP and desalinisation on: http://www.gezen.nl/wordpress/?page_id !1

Salt water is very corrosive. Which would create problems for
the intake system on the steam turbine. Also, you would need a
way to get the left over salt out of the machinery.
