We are fundamentally wrong. We have to see and identify Seawater as the only source of water for all purposes. That I see as the beginning of so...

We need a variety of solutions dependent on the climate of the area and what works best for that are. Conservation is a universal solution and much of the problem can be solved using water efficiently.

I think CV Sundrarajan is right in someway that sea water is the potential source for solving the scarcity of fresh water in the world even for future. But we should devise the technology which must be economical and practically viable. Cloud teaming technology could be one of them which I have indicated previously in my comment. Science is getting more and more advanced today. I think if our institutions could take it seriously this cold be solved in near future, no doubt.

What about brackish groundwater?

Sea water is already the source of ALL of our water; the issue is that it's much cheaper if it's already been desalinated by evaporation due to energy from the sun.

The question is in the industrial application of desalination, but not at the expense of solar energy. A new method of desalination and solar energy is not without evaporation, is reverse osmosis. - A completely new method, gorozdo more efficient and less energy-intensive.

In some how I agree with you, However in the middle east especially in the Gulf countries most of our drinking water is from sea while for other water use mainly agriculture ( aprox. 90%) is from groundwater. This is because the cost of desalination is very high, I wish you all the best in your research and hope you can find the way of cheaper solution of desalinating the sea water.

This method has already been found. It is much more efficient - 85% yield of drinking water, energy efficient, less energoeatraten, less the cost of desalination.

Such a methodhas already been found.And thisis reverse osmosis.A technology,in which85%of seawateragainbecomepotable, but only15%-brine.Cost ofdesalinationis very lowatthis technology.andapproximately10cents.for 1cubic meter.
Anyone interested- write. tumentsev@inbox.ru -
I also agree to you. So far the best efforts are from dry areas like gulf countries. In fact after looking at Gulf countries and their efforts I started thinking and I got motivated that I should do more. Now or so far what humanity did to quench the thirst is too small because we are fundamentally wrong in our approach. I don't think'/feel that i am taking about a big thing . it is very clear to me that our efforts need to apply a factor for correction at Least now.

Please explain to me how using seawater to solve the problems of water in Atlanta.
We are located 250 miles from the Atlantic Ocean and 1000 feet above sea level. We have in 2007 almost ran out of water and are a growing area with the smallest watershed in America for a city this size. We receive 50" of rain pert year. If captured efficiently could supply all of your needs. There needs to be a variety of solutions dependent on the environment of hat area

That is the reason I am stating that we are fundamentally wrong. We are dealing with an issue that is as big as earth with such a localised approach. I can never ever negate all smaller efforts but our global focus need to be on sea water. Because most of global population live close to the sea.I also stated that there could be many chain reactions that will re establish many lost hydrological balances on terrestrial area . I am talking about 96.5 % water on earth but you talk about a much smaller scale. Not even 3.%. Is it not ? Once we get to the real focus (sea water) you can see things will positively change globally

Is sea water infinite? Will the oceans recharge fast enough to mitigate over salting..?

Yes it is infinite when you understand the requirement of human being vis-a-vis the size of the ocean and quantity of water plus hydrologic cycle. There are other chain reactions to happen that will potentially help to escape the terrestrial ecosystem from water stress due to the huge impact due to our wrong doing ( In my view wrong policies) on ground and surface water. We have to make sure that we are making adequate efforts to control pollution. I mean not salinity pollution. Please imagine the size and quantum of water in the sea. All other efforts are too small with large scale environmental consequences. I have a lot to say . I am a Geologist Hydrologist studied in Brussels ( IUPHY programme under IHP of UNESCO) and now working on environmental impacts. I worked in all the three areas Groundwater, surface water and environmental impacts.

If you read the 2004 paper 'A drop in the Ocean for foresight practitioners - what the future holds for water' you'll see similar concerns about how we keep water available for all needs
