This but just filter it. Even a simple rock can filter salt water.

too salty? just add some sugar to the water

How many times did your pimp father rape your crack whore mother while you were in her womb? All those impacts into your fetal head with his big black STD riddled penis would have caused your retardation.

most of our fresh water comes from limited stocks of underground reservoirs. those stocks are running out. desalination for large populations is energy intensive and expensive.

>>14714758
we need this ocean water to consume our plastic, nice idea tho

>>14715929
Just tap the great lakes. Ezy problem solved, next.
>>14715917
Never happened.

>>14714758
Why can’t we filter large amounts of ocean water with a large natural water filtration system wouldnt that be the cost effective method

Are you retarded, Anon?

I mean I am living in germany and most of our wells are also critically low, I have seen them.

>>14716050
Saudi Arabia and the US are already in the process of desalting water. As the Anon said before

You are retarded. Do like 5 seconds of research before you post moron.

ocean water is 3.4% salt by mass.
what to do with the removed salt?

I don't understand how it could be so hard to desalinate water, you literally just have to evaporate it.

>>14717237
it's not hard to desalinate water, there's plenty of things we can do with energy captured by renewables
the issues come from what to do with the leftover brine

pumping it back into the ocean won't help unless it's done at such a wide enough scale that the ocean gets 0.034% saltier--which may fuck up marine life

The best plans involve a circular economy, where the brine is used in other products

>>14717249
Wouldn't it just create salt deposits on the ocean floor, that's what it normally does when it gets too salty.

>>14717237
It takes a lot of energy to change the phase of water. You could re-use a lot of that energy to heat incoming water by condensing the steam. The guy who made segway made a small water purification unit called the slingshot which uses that principle.

>>14717213
Use it

>>14717261
not immediately
and it's not like there isn't life at the bottom of the ocean

the hyper saline brine that gets pumped into the ocean wouldn't immediately dissipate into every single corner of the world, it may do so eventually, but in the meantime the marine life you pump near will assuredly suffer

Dumb questions like this is why I laugh when STEMlords COPE and SEETHE their salaries are a fraction of finance and management. Mr Books.

Nobody has said anything in this thread to prove me wrong.

>>14716455
>Saudi Arabia and the US are already in the process of desalting water. As the Anon said before
Energy intensive and you then have to deal with the brine as a waste byproduct. If it's dumped too close to shore it creates dead zones that are too salty for anything to live in.

...by brainlet magic?

Ok, here you go baby. When fresh water (drinkable water that's not salty), in a river for example (Flowing stream of water) flows into the ocean (big salty body of water) it brings along the minerals its collected from the earth (including salt) and mixes with the salt water in the ocean to make more salt water. When the Sun (ball of plasma) shines on the ocean, the water evaporates into the air leaving the salt (what you put on French fries) behind (because salt doesn't evaporate at low temperatures). When the water in the air condenses (because it gets cold or gets pushed up a mountain) fresh water falls as rain from the clouds (because the salt got left behind). The rain runs into rivers, then the cycle repeats.

You can just add a potato if the water is too salty.

Desalination of the ocean and pumping into the desert is absolutely possible. Yes it takes a lot of energy but we just spent 6 trill on stimulus checks and ppe loans for what? A fraction of that money could have completed this project.

And while we're digging water tunnels, lay down new fiber optics. Hell, for 6 trill you could lay down a highspeed rail going from your ocean desalination, to your desert Oasis.

Wouldn't be easy, but we do have the means.

>>14723607
Fill large basins with salt water
See water evaporate
See this come down as precipitation elsewhere
Precipitation collects in fresh water bodies

Was this so hard?

Saltwater nuclear reactors. Secondary system is extremely long and contains two phases (liquid amd gas) in the loop. As steam turns the turbine, it is ejected similar to a hydroelectric plant, but into in underground cavity which is of the length that the stream returns to water as it exits.
There is a continuous source of saltwater entering the loop yo be purified and provide steam power. There will of course be a standard auxiliary secondary loop for when desalination is secured.
