Basic science of the water cycle.
Water evaporates from the sea, condences into clouds and is blown by the wind to land. As the clouds are push higher by rising land they cool and the water vapour forms water droplets which fall as rain, the rain water percolates through the land, forming streams that flow into rivers which eventualy reach the sea, where the cycle is repeated.

You wish to cut out the evaporation from the sea and forming clouds that rain on the land stage and just have bigger rivers.

How do you imagine this would lower the sea level?

and not suitable for drinking.

ocean water is roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey.
72 percent of Earth is covered in water.

Costs.... The cost of the desalination plants.. The cost of the channels needed to transport the water.. The cost of setting up power plants to power the process...

You're talking about the mass murder of all living creatures in the oceans.... No thank you!

This only goes to show the cancer humanity has become... Cancer cells reproduce at out-of-control rates. We are now overpopulated for our own good.

do you know what 1 centimeters is?

I'm only speaking based on your idea.

In reality, you cannot actually eliminate the ocean, or even reduce it by 1 cm because of the water cycle. Water always go back to the ocean...

If it is even possible, you know by man's eternal greed, it doesn't end in just 1 centimeter per year! By the end of the decade, you miight see it reduce by 50 meters per year!

We could do many things to make this world a better place for everybody not just for the ones who are richer, but we do not want, suffering brings more money than anything else.We live in a very sick society, to change it, the whole world needs to be changed and needs to change.

please read post #3 again

I read post 3... It has nothing to do with desalination and irrigating the worlds deserts.. It was about the US debt... They are two different topics..

It takes a 17.6 sq. ft. solar panel 4 hours to generate 3 kWh in a 12 hour day. That's an average because the days will be longer and shorter than that throughout the year. Somebody elde can figure out the math based on these factors (I might come back later and do it):


Desalinated water is cheaper than bottled water, but 275x more expensive than currently available farm water in the central valley of California. It is affordable if you need water to drink and to take showers, but not if you are using it for agriculture in a world market.

Desalination decreases the entropy of the water and salt (by separating them, that is, by making them less disordered). Any process that does that must be accompanied by an entropy increase elsewhere. From that we can show that energy must be “expended”, that is, turned from a useful organized form (such as electricity) into a less useful disorganized higher-entropy form (such as heat). It is based on the Second Law of Thermodynamics, a fundamental law of physics. The calculation shows that the energy needed is

• 1 kilowatt-hour to desalinate 1 cubic meter of seawater
• 1 Megawatt-hour to desalinate 1 acre-foot of seawater

(If we rounded the numbers to make them easier to remember.)


In the US, the cost of electricity is about 15¢ per kWh retail, 5¢ wholesale. Farmers in California can currently buy fresh water at $4 per acre foot, if they are near the aqueduct. Putting this into a list, we get the costs of fresh water today for an acre-foot of fresh water in California:

• $4 (river water from aqueduct)
• $50 (desalinated water, physics limit, wholesale electricity, not yet achieved)
• $150 (desalinated water, at physics limit, retail electricity, not yet achieved)
• $1100 (desalinated water at Santa Barbara California, using best desalination technology available when it was built in the 1980s)

Now most people don't buy water by the acre so it may be affordable for short showers and drinking water though it would cost a lotmore than the water you are getting now making it unattainable for poor countries and I think that is who we are trying to get the water to here,

And just where are we going to park those mountains of salt?

Hi naveed,

As some have pointed out, cost is the major problem with desalinating water. But, we're working on it. There are, as has also been mentioned many desalination plants already up and running. However, they're really only good in places where water is already very expensive and in very short supply and where the water doesn't have to go very far.

God bless you,
In Christ, ted

Hi jack,

It's always made a good ice melt. Salt is salt. We could stop mining it and use it for table salt.

God bless,
In Christ, ted

Hi naveed,

Another advantage of desalination of sea water is, that if we could draw off enough water, we could equalize the increased sea water created by the melting ice caps. We could actually save New York City. (this is written only and specifically to those 'sky is falling' types that claim the melting ice caps will flood lower land masses.)

God bless,
In Christ, ted

While rtuner in post #12 gives us the key practical information (and does a really good job also on it), it's still great that you want to try to think big.

It's good to think big, brainstorm, and have like 9 out of 10, or more like 19 out of 20 of your ideas going into the trashcan.

That's a good process, if you pay attention to what works and what doesn't and why.

If you keep trying, and paying attention to just how particular ideas fail (like here it just is not sensible in terms of you lose more than you gain if you try to do it really large scale in any area where instead you could just allocate existing water sources better at a far lower cost, for now.....) then by paying attention to just exactly why an idea fails, you will improve and improve, and eventually have a winner. Good ambition to find new thinking.

Oh, and you have it totally right that killing strangers with drone missiles isn't likely to really have a good long term return!

If you want to help the poor in third world countries. There are far better ways than throwing gifts at them.

Those projects that work with the locals always produce better results than those where something is imposed on them.
The locals have to be shown that this new idea/way of doing things works, given ownership of the idea and taught how to do.

The problem with dumping to of millions of gallons of water on the land, apart from errosion, is the salination of the land.

The water desolves salt in the ground and leaves it behind when it evapourates over time the land is too salty to grow crops.

Do you think your nation cares about your well-being overall? If your economy is capitalistic, then the only thing that matters is capital. Millions of "slaves" under delusion of prosperity - ignorant of their status and willfully begging for their own slavery makes money for the type of people who want to go to war. They make money in their sleep.

But, it is much more prosperous to have millions of people pay black market prices for resources abundant on the planet than for the population to be healthy and basic needs met. The formula is simple on a macro and micro level.

The end result must be a complacent, large population that begs for its total slavery, or a small complacent population that accepts its slavery for security and comfort.
