Can desalination end global water shortages?

[@Elazar40]

The sea is also a vast sink for agricultural minerals which can be used to rebuild depleted soils. THIS could be a dual purpose project.

Flushing sweet water down stream and not recycling it is the biggest problem....it is more easy to purify used water than desalination

Top Secret! (1984 movie) Doctor Flamond : You see, a year ago, I was close to perfecting the first magnetic desalinization process, so revolutionary, it was capable of removing the salt from over 500 million gallons of seawater a day. Do you realize what that could mean to the starving nations of the earth? Nick Rivers : Wow. They'd have enough salt to last forever!

[@ben7510]

Why can't they build reservoirs for the brine and let it evaporate or get mixed with rainwater before being pumped back into the sea?

[@KCDustRemover]

Many of the places where they are using desalination for fresh water don't get very much rain, hence the need for the process.

@Joe Eoj You're basically making the same case Thomas Malthus made back in the late 18th century. Unfortunately (or perhaps fortunately?) it's since been widely discredited. It's true that given our current rates of consumption, along with the general disregard for the environment, current rates of population increase will continue to put a strain on our ability to sustain ourselves as a civilization and perhaps even as a species. That said, this is contingent upon current consumption habits that most of the world doesn't adhere to. First world nations, particularly the US, consumes more resources and produces more waste, per person, than all others by a wide margin. So if anything, we should be controlling how much wealthy people can reproduce. Of course if we're smart about this, we'll at some point hopefully transition to a steady-state, non-growth oriented economic/political system and it essentially won't be a concern. Also important to point out that we really haven't had a homeostatic balance with the environment since the dawn of agriculture. So our options are to either transition into a system that prioritizes human needs and sustainability, go back to being hunter-gatherers, or just let the whole thing collapse on its own, in which case the remaining humans that survive will likely end up in something akin to the second opinion anyway.

[@moguldamongrel3054]

Nah that's why the foreigners wanna build space ships and what not. Go fvq up another planet and pretend like they don't know why the system is failing or something.

[@supernovastern1658]

I think they should have mentioned the price of desalinated water and the transport cost to the customer. I´m confident that desalination can provide a stable stream of water to supply citys and other settlements because domestic water has a relatively high price. Sounds like a perfect solution and should be done much more often. But when it comes to providing water for agricultural purposes then i dont see desalinated water being used outside of greenhouses. Growing Rice using desalinated water would increase the cost of Rice about 1$ per kg of Rice (excluding taxes).

[@syedabishosainrizvi7817]

fair point. I guess for agriculture we need to master plants rather than desalination. I read an article a while ago that said Chinese scientists have developed rice that grows on salt water. This could be big

[@QuantumNoir]

That's not really the issue. The main problem is what to do with the waste. You can't throw it back into the water it will utterly destroy the ecosystem. If you just bury it (hypothetically speaking) in an isolated area, that is just a disaster waiting to unfold. One way I thought it straight up shooting it into space with reusable rockets. Yes that's insanely expensive, but usable water will become increasingly valuable so this might not be that bad.

[@HateHater2205]

With melting icebergs making the sea less salty in mind do you think these desalination plants can re-salt the ocean to maintain the ecosystems living in it

The reason is economics. The stadiums earn money, justifying investments into them. The majority of desalination plants are found in Middle East where they can say we save on this much of imported water by using desalination. So, they are using it on a larger scale.

[@moguldamongrel3054]

.... I mean if you designed something as simplistic as a water recirculation system...every time you washed the dishes in the sink, that water would just loop. Particulate matter being filtered out. Install it on showers, reuse the same water, boil it after use, recirculate it. Filter out the soap, hair, etc. Probably would shave off thousands a year off your water bill... Toilet water gets distributed to your garden underground. Plants reconvert waste matter into usable material for plant growth. Anyways.

This video talks about desalination for "remote" communities. Those are desert communities, which need to import their water from distant sources like the ocean. Communities close to the ocean can use ground water (wells) as the salt water that soaks through the land is filtered naturally. Trying to save those remote communities that didn't migrate with the changing climate is a lost cause and a waste of global resources.

[@DavidElzeitsinfill]

One thing we need to do is move water from the ocean back inland to places we need it and if we can do that while generating clean energy we have a chance to mitigate climate change and still have a prosperous future. It is really, really hard but it is not impossible. The biggest idea I am trying to express is tunneling aqueducts from the coast, in this case the west coast of the USA inland to feed combination geothermal power and sea water desalination plants. The idea seems to be so big that no one has considered it possible but I believe it is not only possible but it is necessary. For over a century the fossil water contained in aquifers has been pumped out to feed agriculture, industry and municipal water needs. The natural water cycle cant refill fossil water deposits that were filled 10,000 years ago when the glaciers melted after the last ice age. Without refilling these aquifers there is not much of a future for the region of the United states. As a result ground levels in some areas of the San Joaquin Valley have subsided by more than 30 feet. Similar fossil water depletion is happening in other regions all around the world. TBM and tunneling technology has matured and further developments in the industry are poised to speed up the tunneling process and it's these tunnels that are the only way to move large volumes of water from the ocean inland. The water is moved inland to areas where it can be desalinated in geothermal plants producing clean water and power. In many cases the water will recharge surface reservoirs where it will be used first to make more hydro power before being released into rivers and canal systems. It's very important however to not stop tunneling at these first stops but to continue several legs until the water has traveled from the ocean under mountain ranges to interior states. Along the way water will flow down grade through tunnels and rise in geothermal loops to fill mountain top pumped hydro batteries several times before eventually recharging several major aquifers. What I am proposing is essentially reversing the flow of the Colorado River Compact. Bringing water from the coast of California first to mountaintop reservoirs then to the deserts of Nevada and Arizona and on to Utah, New Mexico, Colorado and Wyoming. This big idea looks past any individual city or states problems and looks at the whole and by using first principles identifies the actual problem and only solution. Thank you for your time, I would like the opportunity to explain in further detail and answer any questions. A better future is possible

If human populations proliferate, global water shortages will persist and only increase. They found in Las Vegas that additional water is fantastic, but management of your existing water is as important. As a result, the hotels became very sophisticated water systems in themselves, though Vegas of course still requires volumes of water. As much as a shortfall of potable water, we also have the problem of location, with some areas wet (such as New England) and others desiccated.
