- We have the desalination technology to transform seawater into freshwater. So why are we not using it to solve the global water crisis?
We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world - and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess.

There was a documentary somewhere on UA-cam about one man who converted a piece of completly dry tarain into a grassy land with some trees smaller plants - so he basically created a microclimate. When this grass and plants grown up enough a few tiny rivers suddenly appeared as well because thanks to plants water was stored longer in the ground. The only downside: it took him 40 years.
It's not a downside. It's the most ergonomic, efficient, and harmless way of sustaining ourselves. People need to stop thinking so small, short-term. It's always about Me Me Me and this lifetime, when our successors are already here.
@Houssain Al ahmafi Yes, and that's a byproduct of western governments where we prioritise short term projects. That is one of the reasons why China has been able to improve so much quicker over the years. They have a long term vision and plan decades ahead. One example is what they are doing with the Gobi desert.
On a small scale, workable. I don’t have faith that huge populations can work together long enough to do that.
Could u please tell us the name of the documentary?

I live on an Island ( Aruba) in the Caribbean and our water plant uses desalination process, water has the best taste. It is cleaned and purified thru reverse osmosis filters and other small processes. At last it goes thru some minerals. And it’s in our tap at home! Look it up greatest tasting water on the planet besides glacier water. (Edit: we have the 2nd largest desalination plant in the world)
That's awesome
Great, how do you handle Brine ?
@@bhavpreetsingh007 Do you mean in the water? I explained above they use reverse osmosis process on the Island because there is no fresh water source so we basically drink from the sea. But we have a great water purification plant!
@@InspireMatrixx hi, understood the process. I was inquiring about the Brine which is the extremely salinated output of this purification process. Do you pour the Brine back to the sea ?
@@bhavpreetsingh007 I understand now what u asked, If I am not mistaken the brine that stays in the filters is recycled or goes thru a process after the filters are changed out but, they don’t throw it back in the sea tho.
My family has been doing something that seems a bit silly at first, but it can save hundreds of gallons of water every year. We noticed that it takes a bit over a minute for hot water to start flowing when we take a shower, gallons of fresh cold water was just going down the drain. We decided to collect the cold water in buckets and use the water to water plants in the yard. We have a decent sized yard. Image if millions of people could do this, it would be hundreds of millions of fresh water saved every year and we wouldn’t need to really change our water usage, just getting over the awkwardness of collecting cold water in a bucket when you shower.
I didnt know other people also do that!
You’d be better off using that cold water to bathe yourself with it. Cold shower first and then warm to hot shower. Most of us do that and it’s normal.
Residential water use accounts for about 6% of total water use by humans. Homes saving water in the way you suggest might bring our water use down by .25% at most. A better way to save water would be to reduce our beef consumption by at least 80%. About 1/3 of the total water we use goes to producing feed for cattle. Reducing beef consumption by 80% would save 25% of our fresh water supply. So, we can not shower, not flush out toilets, not water out lawns, etc, and save 1% of the water we can save by heavily reducing beef consumption.
I understand dropping beef consumption at all is a losing effort, but let your cold water go down the drain. You're not saving enough water to matter in the slightest, even if you convinced every other person in America to follow suit.
@@jessh4016 not in ariOna
U realise water still exists when it goes down the drain, it just goes back through the system and into someone else's tap
Hopefully technology and management will catch up before the water wars.
So much truth in your statement.
We were successful on avoiding the "Malthusian trap" where we might run out of food due to overpopulation due to the progress of science and scientific innovations our crops yields were so high we can manage more than 7 billion people the only problem was the logistics which still made some food prices and world hunger a problem on some areas but more people die overweight or obese like diabetes and old age than being underweight.

@@randomdogger5278 The problem is your govt selling fresh water areas to corporations like Nestle and allow them to claim humans are not entitled to water right.
What energy consumption? If you need something then everything is free. People come together in villages and dig a fucking well, cost free cause they all need it. We have solar power in this day and age, wind turbines, nuclear, etc. Relocate resources to do what they are supposed to do: make lives easier and normal. People who tell you it takes a lot of energy are corporate shills. Sun will never run out of energy and water wont stop flowing until we all die and then some lol.

I like how at the end of the video they tell us, regular people to use water responsibly... When in reality who should be using water responsibly are private companies and governments by consuming responsibly, fixing and modernizing water infrastructure on cities and factories.
Edit: Don't be dumb, of course we have to take care of how and how much water we, it is pretty obvious but let's be honest, those who are responsible directly is most governments for not stablishing proper sanctions and private companies for wasting insane amounts of water and contaminating sources; use your comon sense. Are we responsible as a society? YES! but governments are to blame for not stablishing sanctions to us and companies equitable to usage and companies are also to blame for pushing agendas, or are we gonna pretend that companies are all angels made of pure light?
You have a good point on private companies. But I wanted to leave you with a positive outlook and highlight that how we use water is as important as the technology we develop.

There needs to be MAJOR funding in desalination, there should have been more funding for decades
Maybe what is needed is for humans to be more responsible with what we have instead of starting to drain our oceans when there has been toxic dumping for years.......
yep

This is another reason why we need nuclear energy. The reason desalination plants are so expensive is because they require huge amounts of energy, and nuclear will compensate for that due to producing high amounts of energy quickly and efficiently, and that will in turn make desalination more efficient.
@@Fultonfalcons86 keep dreaming bud, we need practical solutions to solve the problems we created for ourselves, and human responsibility is not practical

@@ishid_anfarded_king That is a bogus argument. If I kill 100 people this year, can I brag that it is better than the 1 million I killed last year?
This is a great video because it shows multiple sides of the problem. A lot of video, whether here on YT or "standard" documentaries on TV, often only show one side of the problem - i.e., "look, here is the solution to our problem". The better documentaries show also the downsides of the technology. But here, not only is the up and down side of the technology shown but also alternatives. I really liked the ending with "desalination didn't saved Cape town, using less water did".
Excellent work!
I really like your videos, because issues are presented for different perspectives, for the better or worse. I think though that in this one in particular another issue should've been mentioned: water leaks.
Very often the biggest water waste doesn't come forme citizens, but from water leaks in the pipelines and an inefficient use of water in the industrial and agricultural sector.
I know that this isn't always the case and for some countries and some areas desalination is essential, but for many other cases the priority should be the efficiency of water use and transport, from treatment plants to the final user.
Also, many countries are starting to invest in more efficient wastewater treatment plants, that allow to use the treated water in agricolture or even as drinkable water.
Anyway, I understand that all of these subjects would've taken a lot more minutes and made the video endless, it would've been nice to mention them briefly though.
I would also love to see a video made by you about all the different solutions to face the water crisis. Maybe you already published it!
In conclusion, great video overall, keep up the good work!
"wastewater treatment plants" big yes :)

I have been a reverse osmosis technician for my entire naval career. I can tell you that it is very effective, but does require a lot of expensive consumable resources including plastics, filters and minerals such as calcium hypochlorite, and bromine. It’s basically like using K cups instead of brewing a pot.
Evaporators require a heat source, but are extremely effective and efficient at demoralizing water, but the aspect of adding minerals and chemical treatment still exists.
Singapore has created a type of reverse osmosis facility that transforms all of their waste water back into drinking water. The end product is very pure and healthy water and is very efficient.
IMO, we could take a lesson on that for our coast lines. However, due to the consumerist/capitalist nature of our economy, I would think these types of facilities would put a huge tax on drinkable water.
The man has to get paid after all
these are all great insights!
Question please: I live in a hot country where temperature rarely goes below 30 C, if I point several magnifying glasses at water, wouldn't evaporate? (and so I could just stick a tube out of the container to get distilled water)

Previously, this reclaimed water would have been treated and dumped back into the aquafer, instead it's put to good use.
@@gizmoapangalook121 He doesn't mean that, greywater can be used even at farming. You'll have to use special types of dishwasher caps etc but even if you don't want to or it's too expensive you can cleanse the greywater from harmful chemicals using some non edible plants and even fish. I know that it sounds complicated but anyone can do it easily and it doesn't take much space (unless you live in a block of flats) but there are water usages for in-city greywater use. Like filter the greywater and sell it to carwashers (they do it in germany a lot) or use it for the toilet
What you are missing is the fact water is heavy and it costs money to ship. By the time it gets to its destination it is 3 times more expensive. Btw nestle sued the us govt and won. We no longer have the right to clean drinking water. This is a manufactured problem. Also some countries all the water rights are owned by coke, Pepsi, and nestle. Let that sink in.

Southern California needs to invest in many desalination plants.
The San Diego area already has a huge desalination plant that reportedly puts out 50 million gallons of fresh water per day. It currently only costs about half as much to import water, though. It seems to me like it would be cheaper (in the US) to simply build a few pipelines to ship water from the Northwest to the Southwest. In fact, a federal water sewer could work nationwide, sending water all over the country from areas that need to get rid of excess water to prevent flooding. This is why we need a government that works, instead of one that is stuck in an intractable battle of opposite sides of the ideologue spectrum.
Nah, they'd rather spend the money on a high speed train to nowhere and gripe about how they don't get enough from the Colorado river.

Desalination plants could easily provide all the water we need, and provide us with sea salt as a byproduct for animals, and humans.

Desalination plants uses quite abit of energy to convert sea water into drinkable water. It can turn out to be rather expensive for under developed countries.

So from what I can tell, there are two forms of desalination shown here, membrane desalination and evaporation desalination, evaporation desalination produces salt and no brine but membrane desalination produces the bad brine. Why not just use membrane desalination to produce the bulk of water (because its cost efficient) and then evaporate desalinate the water out of the brine and just sell the salt to eat?
That's my thinking as well. Brine just has a much higher concentration of salt than normal. So we use that to our advantage in salt production.
That's a great idea, but I think you would have a lot of extra salt on a massive scale, somewhat like the red mud problem from bauxite production. One possibility would be to melt the salt with silica sand into glass, perhaps in solar furnaces set up in the desert, and use the cooling energy to produce electricity. Or store the salt in the driest deserts on Earth that are already salt laden.. It's a salient problem!
Unfortunately, both methods produce brine.

Its not just the amount of freshwater but it also the amount of pure/drinkable freshwater that we need to resolve.

I see Brine as a valuable resource in the preservation of various foods. Another solution to the brine problem is having a salt farm right next to the desalination plant as a very cheap way to process and make sea salt as a byproduct.

Perth Australia has been losing 1% annual rainfall each year for about 20 years. The water catchment areas can no longer produce enough water to flow into the dams. The city has an artesian basin under the coastal areas under Perth, which can be used for a while, however eventually than level will drop and sea water will pollute the coastal areas of the artesian basins. The government was faced with limited options. There is a dam in the north of the state, but the dam is about 2,000 km from Perth. West Australia is a big and dry place. To date, the State government has been building desalination plants. Some people complain that desalination plants are unnatural, but in fact, they are a reflection of nature, with water evaporation from the sea and forming rain clouds then rain. So far 50% of the city is using the two desalination plants currently built. Any excess water is stored in the old dams in the hills. A third plant is planned.

It's so surreal that we were facing day zero in 2018. It feels like an age ago with everything going on with covid. I still don't flush the toilet every time so that I can save water lol, it's just ingrained in me now
Same. Our dams are the fullest they have been in a long time and I still shower with a bucket.
As those in the mountains say, if its brown flush it down..., if its yellow, let it mellow.
Perth, Australia has two desalination plants and also purifies its waste water to recharge the main aquifer supplying the region. The desalination plants draw most of their power from wind farms, reducing the load on the environment.
And they single handedly solved the drought problem in WA

@@johndor7793 The joke is that countries like the US use a butt ton of water to make certain foods available all year. These foods are grown in arid areas where it needs an even higher amount of water to grow these foods.
@@msaag5490 why not just import it from other places.
@@msaag5490 plus companies that sell water in america wont be happy. cause face it with draught issues that benefits companies that see bottled water like example dasani by coca cola. the demand for bottled water will increase and if so companies will raise prices since eventually ppl dont got a choice or most wont know shit on alternatives like filtered water for example or just lazy. moment theres a alternative for water usage which is the sea if this fully goes though then similar to say tin foil (think was tin foil, maybe wrong on this and another item long ago instead) when first invented ppl throught its a rare resource/commodity and prices were high. but when ppl realize its damn easy to make it the price for it plummeted. same for water. water prices will plummet a bit when ppl realize its now more accessible and draught issues is reduced. water companies wont be happy if they start losing sales monthly if ppl find easier alternatives to gain water and cheaper in mass. and those companies will find ways to blame the one that caused all that knwoing history of companies suing one another on stuff involved with that.
random/side thing: its like the whole hyperloop train thing too on it will mess with companies involving travel.
the one plan is from san francisco to L.A. avg driving time is 5-7 hours. flight time is 1-2 hours. hyperloop is avg 30 mins.
for driving: hyperloop will for sure reduce companies services on ppl needing gas, hotels, car repairs, snacks, diners, and so on from SF to L.A back and fourth. if alot of ppl use hyperloop imagine the loss on sales/services for those companies that rely on ppl driving from those places to another? they wont be happy and find an excuse to blame/sue hyperloop company for "damaging" their business.
for flying: similar with less ppl flying from those places to another. avg flight ticket costs 100-400 (depending on season and which seats.) round trip. if more ppl use hyperloop instead of flying for say those on business trips thats a lost on ticket sales for airline companies. similar they wil lfind a way to blame/sue hyperloop company for interfering with sales.
note thats just for sf to la. theres info of more is planned from i think chicago to detroit or something and few outside of america like in united arab emirates.
@@stan5555 That doesn't solve anything. Water is a universal resource that everyone needs. If you exported it from some place, that means your taking water people in that area can use. That's fucked up. And no, supply-demand economics shouldn't be used here. Everyone needs water, it has inelastic demand.
i used to live in Saipan(CNMI, USA) and we use desalination for tap water. The water will still be SLIGHTLY SIGHTLY salty( it just doesn't taste as good as pure water). And we locals will only use that tap water to wash things( wash veggies, shower, laundry, etc) but for cooking we use imported bottled water from South Korea. And the reason is that after you settle the desalinated tap water in a water basin for a few hours, and you'll see white mineral deposits at the bottom of the basin, so think how bad it will be for our teeth and body and hair? Most girls use the tap water to wash their hair followed up by rinsing in pure bottled water so keep their hair healthy. Even our toilet tanks have HEAVY mineral deposits. Oh also, since Saipan rains everyday, most houses have HUGE rainwater collecting tank, so we shower with rain water instead of desalinated tap water, we also use that rainwater to do laundry.
Lmao, so what was the point of desalinization then?
@@LeoMkII Well, not everyone can afford a rainwater tank and also to those people that live in apts.
Lanzerote has an amazing desalination process was one of the first places to do so
I’ve said this since the 80s but if you have the power over it you can charge whatever you want for it that’s why they won’t do it
May God put you and those who think like you as far from power as possible.
@@musicfan1517 unfortunately it is called “reality“
Remembering my travels to Curaçao. Amstel brewery has a desalination plant there (or uses the water from it), resulting in very nice beer
Thanks. Please cover how many water tables are below the ground. We need more drilling since most scientists do not agree.
There are many undiscovered aquafers. Please interview experts on this.
ALso since nature can fix things over time, you need to experiment more. For example build a Large are for a lake and dump all the brine in there and study how nature addresses this over time !!
Make a 100 acre lake and fill it with brine. Plant salt tolerate plants and trees, etc
They study how nature cleans it !! This would be a learning project !!! Keep up the great work!!
Build one in the desert and also non desert area. This is how we learn !!
Why don’t we collect more rainwater throughout the year so we can have stored water on hand? Especially if we did this in areas more prone to flooding. If you put it underground reservoirs we could keep it cooler, and not exposed to direct sun/wind so it’d prevent evaporation too. I get there’s acid rain but we can filter, chemically treat or boil water to make it safe to drink.
Interesting approach, thank you. We will look into it.

A neighbor of mine was a retired Westinghouse engineer, He had worked on nuclear power plants. He said the biggest mistake Westinghouse made with nuclear power was not including desalination facilities with the power plants.
1. Location, not all nuc plants are on salt water 2. salt water is NOT circulated through the reactor. 3. Any nuc plant near salt water could add on a desalination plant if desired.
@@fredkibler The main issue is that Nuclear Reactors run at a below maximum efficiency, as a safety factor (at high efficiency there is very little time for human reaction to an emergency), this means they have a tremendous amount of Waste Heat, which would be great to run a Distiller/Evaporator to purify ocean or brackish water into drinkable water!
This also will lower the amount of hot moist air being shot up into the atmosphere since you would no longer need all of those large cooling towers. An even better solution would be to have the plant near where a city lets out it's treated fresh water into the ocean..... They could mix the Brine discharge from the Water Plant so there would be minimal disruption of Ocean Life from water being too high or too low in salinity being discharged into the ocean.
(Former Water King aboard two different US Navy ships)
@@timengineman2nd714 I'm gonna give you a gce on your 1st paragraph. Mixing could be done but then why would a city low on fresh water be dumping it, they would be better off treating and reclaiming it so that only a minimal amount is lost. Brine should just be sent to evaporation pools or something similar to collect the salt.
wrong. co locating drinking water with nuke waste is not bright.
@@joeyracano1 no one's talking about that
Evaporate water from brine and sell the residual salt for a profit, use remaining brine to grow tomatoes and all, take the profit, build a space company with that with reusable rockets, explore and mine necessary material for solar panels. Now you have clean water, unlimited solar panels, and a shitload of tomatoes and salt.
I know, easier said than done, lol.
Well, with no other option available your is a greate idea, still it's not economically competitive as the little of such problems
@Dillon in some ways, you are right. Solar panel right now is not very efficient. That's why we should use nuclear energy more and solar panels for small scale.
@@balashibuyeeter2704 small scale? if every company or building adopts solar panels in their infrastructure, either vertical or horizontal...it will create a lot of eco sustainability in the cities. people gotta realize vertical use is also possible.

Uses for the brine, from Britannica; "Brine is used as a preservative in meat-packing (as in corned beef) and pickling. In refrigeration and cooling systems, brines are used as heat-transfer media because of their low freezing temperatures or as vapour-absorption agents because of their low vapour pressure. Brine is also used to quench (cool) steel." and from Wikipedia; "Brining is used to preserve or season the food. Brining can be applied to vegetables, cheeses and fruit in a process known as pickling. Meat and fish are typically steeped in brine for shorter periods of time, as a form of marination, enhancing its tenderness and flavor, or to enhance shelf period."
Since you talk about water usage, I would have loved to hear a comment about industry and agriculture use. Thanks for the video.
The agriculture I understand. I’m from central California and we provide, if I’m not mistaken, 30%-40% of the USA’s food such fruits and veggies.
@@JohnnyVasquez8 animal production uses like 70%
Nuclear power which is one of the safest and most sustainable energy sources can easily be engineered to use salt water for cooling producing steam that can be collected as fresh water. Two birds one stone and cost effective
And what are you going to do with the tonnes of salt you produce as a by-product? Are you going to use the same salt water to cool the vapor down to condensing point? Do you know how much more maintenance goes into cleaning the heat exchanges in a salt water cooled system? Just food for though.
I sense a potential radiation contamination problem... In any case through electrolysis you can always turn the salt into other by products... Perhaps get some chlorine for other things
@Jerry Davis stop trying to insert US politics into random topics where it's not relevant. No one gives a shit about the details of your country's political situation. Just stop already
@@skyreapery2n164 there is no cross contamination, they are in separate loops. Using electrolysis is using a lot more energy for minimal gains.
@@kaeoss4478 I'm sure over time it could improve to become easier
What if to combat the excess brine water, companies could possibly make salt water batteries? If that's a thing.

There is a super easy fix to all the super salty brine. Just pump it inland to a dried up lake bed or a man made lake bed. Let the water that is left soak into the earth replenishing the aquafers and evaporate which would create more clouds and possible more rain for the region. Plus then you can havest the left over salt. This would avoid damaging fragile ecosystems along the coast.
Yes zemtek you are correct .. how abt starting to do it together in India ??!!!
@@rafeeqkhan6268 it should be done all over the world.
There are a number of videos that show ocean water being used for farming with certain plants. More research needs to be done with using ocean water.
Salt destroys farmland. It might work for the first harvest, but after that, the land is unusable.
@@Drakey_Fenix Remember ocean salt is not the same as table salt and next what is your scientific study on your statement.

"Flush only when you really need to flush" - yeah right, and how exactly are we going to deal with sewage that is 5 or 10 times more coondensed than now? XD
Sewage plants will be fine, your pipes would probably be fine as solids will have a longer time to break down before you flush. I'm not sure how this is actually a problem aside from the home sanitation factor?
Very good pint. Many sewage systems are not built for periods of draughts. Cape Town did a great job in using less water during the drought, but their sewage system almost collapsed. Stay tuned, my friend. I am working on a video about this problem for this channel.

I always wondered if a large scale solar SeaSalt setups could utilize a plastic water collecting cover of some sort. They're evaporating hundreds of thousands of gallons to get these brine pools, a ridged plastic tarp could direct all that distilled water to a collection system.
Exactly. Freshwater is a valuable natural resource. For people who already have sea salt drying pool set ups they’re literally allowing money to evaporate into the air when they could be collecting it and putting it to use. In very arid countries the water they could collect would probably be far more valuable than the salt
Turn into a business model and your in, and yes evaporation works
“Solar updraft generation”.
@Faux Que We also have these things called Winds... Guess what happens when they push all that heavy water vapor away?
Africa's Deserts for example have winds blowing West and actually help fertilize the South American rain forests.
So if say... you needed water in Africa, you'd want to catch that water vapor IN AFRICA and not have it just be added to South America's Rain forests.
@Har By Why wouldn't Nestle collect that water and sell it then?
100% Organic natural carbon free electrolyte infused solar powered water! only 5.99 a gallon.
My whole point is it's there and evaporating already, just being wasted.
As always, conservation is cheaper than expanding the supply of something. That doesn't mean that we don't need desalinization, but strong conservation practices should be put in place anytime water shortages are severe enough to justify desalinization.
It would place importance on the need to recycle wastewater while still building desalination plants. Do not waste a drop of freshwater. That message must be pounded home.
No somebody is stealing the water
