why scientists are unable to transform sea water into drinking water,which can solve all problems?

Question

i mean to say the cheaper method of desalnisation

Answer 1

your question is incorrect. it is possible to transform sea water into fresh drinking water, but it is difficult and expensive because you have to remove all of the microscopic material, minerals, and -- most significantly -- the salt from the water before you can drink it. The nation of Israel obtains much of its drinking water by purifying the salt water of the Mediterranean Sea, and many US Navy ships (and probably those in other countries) obtain their drinking water directly from the ocean. But this won't solve the drinking water problems of most countries because it is a very complex and expensive process, and most nations can't afford it for the populace as a whole.

Answer 2

They discovered how to desalinate sea water a long time ago. At Shark Lab (S. Bimini, Bahamas), we desalinated sea water continuously for our cooking, drinking and bath water. It's a slow process, and we were trained to use water conservatively.
For instance, we were only permitted a quick 5-minute shower a day. And it was HOT, humid there, especially after being in boats or in the sea water, studying and following sharks all day.

Answer 3

They can do that. The process is called desalinization. They actually remove the salts from the water to make it potable.

However, there is a downside to desalinization. It costs entirely too much to process sea water. Most places that need it could not afford it.

Answer 4

It would be much to costly to transform sea water into drinking water. It just wouldnt be worth it.

Answer 5

St. Thomas in the US Virgin Islands has a reverse-osmosis plant built by Isralies, and it functions quite cheaply, all things considered.

Something that I find interesting; nano technology used for water purification:

Answer 6

They can, it's just the fact that it's so expensive to do so that's the problem. If somebody can find out a cheaper way to do it, then our problem(s) would be solved.

Answer 7

Water can be purified easily and cheaply using a solar still. It just doesn't solve all our problems.

Answer 8

this is done in many countries as their primary source of water example barbados

Answer 9

they CAN, but de-salinising plants are expensive.... would you pay 5 dollars a gallon of water?

Answer 10

both because i heard that in china there is a purification facility(s)for seawater
