They already do this in Florida. Some cities distill the water from the ocean and convert it to regular drinking water. They store it in case of droughts and incorporate it with the regular drinking system. They also have 5 desalination plants in Kuwait.

there is a way of making plastic tubing so that it is only poris enough to let the H2O water molecule through, it involves making the tube in a liquid and bubbling something through it, anyway when you attach many of these tubes to a suction system and plug off one end the negative pressure in the tube sucks water through leaving everything else behind. Thus pure fresh water, even leaves out bacteria and such.

We will never run out of water in our lifetime, and probably in a few generations to go, so it doesn't concern me mwuahaha. Actually, it's very unlikely that we would run out of water anyways.

Your idea has many flaws and is too vague, sorry,

well first off, we are not running out of water, the same amount has been the same for the past billion years. It is however being polluted, anyways...

Its also dangerous to alter the fine balance of salt and fresh water, the freshwater when rained into the ocean will cause a imbalance and result in catastrophic events ( its why the red sea is no longer a FRESH WATER Lake/Sea)

The best thing to do is produce a controlled system of H20 for the HHO Gas ( Water as a fuel) Engines so we do not tamper nature

a controlled enviroment with water is to make water from Hydrogen and oxygen, pure. then put it controlled into the gas stations, and when used, converts into a gas that cannot revert into water

thus, fresh water and salt water is still in a neat balance and wet get distilled water without it being fallen into the system

Hi,

I think that we will run out of water for I do agree that we have the water cycle and all but due to increasing pollution and all the rains that we get are mainly Acid rains which ratehr than being good is bad,

Fine we start using sea water but knowing how human species waste, the water is gonna be wasted like crazy. We are already polluting all the water bodies with any trash possible which is in turn poisoning all the water animals and promoting algae growth.

I actually dont like the idea of desalination for it will result only in more wastage and pollution UNLESS the younger generation does something about this and takes care of nature.

Cheers

I agree that water is one of the alarming problems in this century but we are improving our green movements are getting more and more enrolment. And we are starting to think about out survival and about our offsprings. We have problem with pollution of water we have problem with lack of water in certain parts of world too.

I really don't have good suggestion for how to solve this problem but extracting water from the sea is not good even if we used ice it wouldn't proved much better as the fact is when we start using sea water we will shift the delicate balance of the sea its saltiness will increase and we would see major changes in sea currents which could then affect climate changes around the world especially Europe climate. Which would change rapidly and we could see new Ice Age comming. Safara would become rainforest instead. And so on however this rapid changes would extinct all those species who adpoted over centuries to the climate and affect human race also which would lose mush of the historical heritage millions of people who survive frost and cold would become refuges in regions not ready to accept them or not wanting to accept them and so on.

This would bring chaos it would mean less food less drinking water available over long term. And those who are lucky to survive this climate changes would have to start from beginnig like we were before 2000 years or even more. DARK AGE FOR HUMAN KIND.

Actually, that idea is great for getting the salt but not water. In fact that is how people around the world obtain salt. Then take water from the ocean and leave it in the sun, the water evaporates leaving the salt. In order to get water you wud need to condense water vapor, which is pretty uneconomical.

I do agree with the post above mine in that the original proposed solution extracts salt and vaporizes fresh water. For it to work, I think one would need a condenser? In any case, the idea of a solar-powered distiller is pretty nice, don't you think.

Now, I know a lot of "factual" people insist that the world is not running out of water. However, I do believe that the problem being adressed is the shortage of fresh water in certain areas of the world. For example, I heard that in the outskirts of New Delhi, capital of India, water has become an increasingly scarce commodity. People trek to wells in the outskirts of the city just to fetch water for their daily use.

In some villages in Africa, potable water is also a scarce resource. True, they have an abundance of rivers and streams but most of these bodies of water are infested with microbes and/or toxins. (Recently, however, a device called Lifestraw has been introduced to filter out these harmful substances)

The way I see it, the problem is not the existence of water, per se, but the availability and transport of fresh water to inland areas. It is not true that we can always just rely on rainwater or springs because, oftentimes in heavily populated areas, people draw it out faster than the weather can replenish it.

In any case, I can see different ways to solve this
1. Use less water. Really, anyone with common sense can see that you can recycle water for your daily chores. Instead of flushing down freshwater down the toilet, we just use the suds and wastewater used in laundry.
2. Recycle water. I meant recycling sewer water, not just laundry suds. I do believe there is a forum thread about this somewhere.
3. Draw more fresh water from other areas. By this, I meant the import of freshwater from other cities, or even neighboring countries.
4. Draw freshwater from the sea. Only, for this to work in a country, we'd need desalinisation plants, long-distance conduits and water tanks.
5. Import freshwater ice from the polar caps.

But, really, won't it be much easier to conserve water, like #1 and #2? Or build purifier plants like #3? In other words, I do believe it is much easier to clean water that's on our doorstep than to clean water from a coast several miles away. Don't you guys think so too?

Plant more tress. They use water, yes, but they also filter it and cause the water to stay in the ground by avoiding runoff ( the root systems ) and promote a healthy eco-system for providing cleaner water , lumber, and if they are allowed to decompose, a natural fertilizer for better soils and a micro-biotic environment. Every part of the Planet would benefit if we weren't chopping down all the trees...

I beg to differ. Not every part of the planet will benefit from trees.

I once read a book that has some theories on why the Sahara Desert grew to such a size. It said that the rise of the Himalayan ranges, pushed up by India driving inland, caused the redirection of the cooling rain-bearing winds from the East. It was a slow process that took a very long time but, as you can see, a daily dose of searing sunlight has taken its toll on what was once lush greenery. No amount of tree planting could save that area from turning into a desert.

Similarly, some heavily populated rural areas (or even the outskirts of urban areas like New Delhi) have no connection to water services. The easiest approach woukd probably be to draw water from the ground. However, if everyone also drew water from the ground, then groundwater will be used up faster than it is returned by natural processes (rain or snow). As you can see, planting trees will only cause more problems.

Like I said in my previous post, the problem is not that we are running out of water; we don't have our oceans drifting away into space. The real problem is the tramsport/delivery of water to certain populated areas. However, if you wish to look at it differently, the problem could also be that people are living in areas where water is hard to come by
