How Aircraft Carriers Turn Seawater Into Fresh Drinking Water At Sea
HTML-код
- Опубликовано: 25 апр 2023
- We explore how US aircraft carriers use desalination to provide drinking water for their crew on long missions. Desalination involves removing salt and other minerals from seawater to make it drinkable, and it's a crucial process for the sailors and crew of aircraft carriers who spend long periods at sea. We discuss the two main methods of desalination - thermal distillation and membrane-based reverse osmosis - and explain how the latter is the most common method used by the US Navy.
We also look at the history of desalination, including the ancient methods of evaporating seawater to remove salt, and the more advanced methods developed over time, such as reverse osmosis. We discuss how the Navy has been working to make desalination more fuel-efficient, including the development of the EUWP Gen 2, which uses 65% less energy than conventional technology.
Furthermore, we highlight how desalination is becoming an increasingly popular method of water treatment worldwide, especially in places where fresh water is scarce. We discuss the challenges associated with desalination, such as the high cost and energy consumption, but we also highlight the incredible potential of this technology to solve water scarcity on Earth. #aircraftcarrier #usnavy #drinkwater
I was on the U.S.S.Constellation in the 70's. The ship's desalination systems were a mess and in need of major repairs. We were due to go home but were called to the Indian Ocean instead for a " show of force ". It got to the point just getting a drink of any water was nearly impossible. No showers, no laundry and no water coolers. We would sneak into the officers mess at night to fill cans of water to drink and that even reeked of jet fuel. Being over 140 degrees F on the flight deck we were dropping like flies. After all these years later I still treat water like gold.
A good story. Sorry that you, and your mates, had to suffer though.
Fresh Water is indeed liquid gold. Us just being in developed nations having it on tap and handy tend to take it for grant right?
Priority order for water from the evaps is:
Boilers
Galley
"Hotel Services" Showers/Laundry/General cleaning.
Blame the lack of water on the CO, not engineering. That Oiler that kept your JP-5 topped off was quite capable of transferring raw distilled water, boiler feed, or potable water. All he needed to do was swallow his pride, admit that his ship had a problem, and order up a few thousand gallons. That's why there was a padeye for the RAS cables installed near the Water Inlet...
The Evaps were considered critical engineering equipment. Spare parts up to and including complete units should have sailed with the battle group on one of the Replenishment ships. If not available onboard, then whatever was needed should have been airlifted out to the BG or closest shore installation and cross-decked until it made it to where it was needed. Again, a possible pride issue...First step is to admit that your ship has a problem. From the carrier POV, a matter of ordering the parts and letting the support ships handle the logistics.
As far as petroleum products in the water goes, there was a leakage issue or somebody screwed up and put the wrong liquid in the wrong tank. I spent my time on a Replenishment Oiler that carried more fuel than your carrier did, and NEVER noted anything indicating a contamination issue. With 5 million gallons of DFM (Boiler fuel) and 2.5 million gallons of JP-5 onboard in like 20 tanks, I'm sure that there was ample opportunity for a screw up, but it never happened.
Wow! Glad you SURVIVED, even though it was off POISON. INCREDIBLE!!!!
Whatever RATE, FALLS UNDER THE PROCUREMENT OF THIS OPERATION, has THE MOST "IMPORTANT", and TAKEN FOR "GRANTED" JOB ON ALL US WARSHIPS. NON COMBAT VESSELS, included.
I served two combat tours (1972-1974) as an AT in Vietnam aboard the USS Ranger (CVA-61). I've learned since then that the desalination processes also drew in Dioxin, as in Agent Orange. When Dioxin & salt water merge, Dioxin becomes 10X's more potent. The Ranger's water system became so contaminated with Dioxin, as in 100 years worth, the Ranger, along with other Blue Water ships, was scrapped completely! I defer to "Military Intelligence" to cover up the evidence. Thank you, Monsanto & DOW Chemical!
Dioxin? Ever hear the line "Hook, line, and sinker"? Somebody fed you the whole tackle box...
The "Desilination processes" onboard ships of the time was Distillation, resulting in chemically pure distilled water. We're not talking the "distilled water" your wife buys for her iron to iron her dresses, we are talking literally Lab Grade distilled water. Trace minerals need to be ADDED to this water to make it safe to drink.
I'm guessing that you are a follower of an organization with the initials BWNVVA. They have ONE major goal for existence, that being to ensure that you are scared by their propaganda enough to pay your annual dues and contribute regularly in order to run their bank account up as high a possible.
This organization makes much of using "contaminated" inshore water for production of shipboard potable water. The reality is that the regulations exist in order to prevent fouling of the Evaporator intake filters due to the higher levels of marine organisms and other solids found in inshore waters.
The "scientific tests" which show that the distillation process would actually INCREASE the Dioxin content of the final product used distillation methods not even close to what the Navy was using in the 60's and 70's, and failed to include the additional steps taken AFTER distillation.
FWIW, it wasn't potable water contamination which caused older ships to be removed from service, it was the fact that firing boilers with oil is very expensive.
Steve, I have real difficulty with this as a chemist. Seems improbable and not information. Like where did the "Dixon" originate? A bad water system caused the ship to be scrapped?? This all sounds improbable.
@@DGill48 I found myself unable to construct a tinfoil hat sufficient to completely understand the theory, but it appears that they are blaming it on a combination of taking on contaminated water from shore-based municipal water and using ship's distilling equipment while close inshore where the waters were contaminated.
Apparently the Dioxin was not detectable during the battery of tests ran before introducing water from ANY source into the ship's potable water tanks.
To improve throughput and increase efficiency, shipboard Evaporators run at a vacuum to drop the vaporization temperature. Raw water is pumped through the Evaps and a small amount is vaporized and condensed, with the remainder going overboard.
I could almost see 1,4-Dioxin with a BP of 75C/167F ending up in the condensate, but (at least in the 80's) hydrocarbons and chlorine compounds were specifically tested for, as were dissolved flammable gasses.
In any case, Evaps were generally secured while running close to shore to avoid processing raw feed which might be contaminated with chemicals, bio load, silt, etc. Due to the low-temp distillation process, a heavy bio load wreaks havoc on the Bromination process used for treatment, and NOBODY wants to tear down and clean the Evaps.
Backing up a bit, the Evap output goes to holding tanks, is tested, pumped to specific tanks, and is then pulled from those tanks and treated appropriately for either Boiler Feed or Potable Water for storage as appropriate.
The Evap output is pretty much lab-grade distilled water. First purity test is a pretty sensitive Conductivity Test. Single-digit readings in the uA range are enough to divert the Evaps to the bilges. After that comes lab testing. If it passes it either gets Boiler Chems or trace minerals and Bromine.
@@DGill48 if it rains in Vietnam. Where does all the water go? To creeks, then stream, stay with me here. Rivers, then woah the OCEAN, like gulf of Tonkin. Now I’m assuming you watched the video, where does the USN get its potable water from? Oh yeah the ocean. Obviously not as smart as you think, and this has been proven and is being compensated by the VA blue water navy act. FD!
Correcting some of your issues,
1) Nimitz class aircraft carriers do not use Reverse Osmosis (RO) units to make distilled water. they use 4 7 stage vacuum type distilling units. each one is rated to 100000 gallons of water a day. the ships normal operations normally only need 2 in service to make up for all operations a Nimitz class carrier can do.
2) the water from these distilling units are so pure, they have to add salts back to the waters before it is aloud for human consumption. reactor and steam plant water purity requirement require the water made is grade 1 water. RO units are not capable of producing Grade 1 water in the quantities required for a Nimitz class carrier's continuous operation. the major loss of water onboard a Nimitz class aircraft carrier is from its steam catapult systems.

Magnificent methods to produce water. Awesome job by the Navy.
Have you ever tasted it? It’s like diluted seawater, which is exactly what it is.
USS CARL VINSON CVN-70 and was amazing what we could produce. This is a key to our survival. Keep pushing technology.
Waiting for your analysis for a long time, indeed you gave us in depth viewpoints 👍
Love your videos as always! I can hear the passion in your voice too. Keep it up please! 👍
When did the Navy get cruise ships?
Lol. Cruise ships use the same method to make fresh water...
@@RetiredSailor60 Yeah, that picture being in there might have made sense, had they mentioned that the same method was used elsewhere. Given the narration was just talking about Navy ships, then that cruise ship clip comes through, it's just comes off as out of place.
I've taken several cruises on Navy ships.
Desalination plants on the shore could be the alternative for constructing massive and very costly dams, taking away huge fertile land from farmers. That method can be made cheaper using floating solat plants.
An interesting video ....a lot has changed I remember as a young ''Snipe'' on the U.S.S. Lockwood FF-1064 stationed in Yokosuka Japan from ''81 to ''83! We had superheated steam converted to fresh water..and there were restrictions on ''Hollywood showers'' while out at sea! So we would have to do the quick ''Navy shower''...soap up and rinse off..now all of these years later as an old man I ENJOY ......my ''Hollywood showers''!!😁😆😅🤣
@@kevincrosby1760 Ok..I was not a B.T. I was an E.N. in ''A- division so I didn't have all of the technical terms of that particular rating!
It started on the aircraft carriers then Cruise ships implemented that technology and could be practical on land.
Water would be much more expensive however at some point will need to happen.
To navy produce
I was on the U.S.S Gerald Ford I went under the ship and saw all of the filters very cool for one big ship
Thanks for the information very valuable.
When I was on a carrier, it took me 40 minutes from seawater to distilled water on a start up.
How many others caught the error in this piece? When they mention cruisers, they show a photograph of a cruise ship. Ha ha.
Aircraft carriers are amazing!! 🔥
Yes it is a very informative and interesting video just keep it up.
This is quite interesting, I have been thinking about this for many years that we as a country should start this process to pump the areas where the lakes are polluted that people can get fresh, drinking water or droughts as you said. But it’s getting the government to actually do something For the people. Thank you for this presentation. 12:15
It's expensive and produces lots of salty water. Saltier than regular sea water. So dumping it back into the sea will harm the sealife around your coast. Those are the two main reasons salinization isn't used.
Also Grand Moff Tarkin is in this movie!
@@thebookwasbetter3650 thank you for that information, I didn’t realize that. Would then it be possible to take the salt that is extracted from the sea water to then sell it as salt crystals instead of re-dumping it into the ocean? I’m just curious because they sell salt crystals now for table use, but that be something that would be possible?
"But it’s getting the government to actually do something For the people."
One of my professors (Governmental Budgeting) had a saying - "Don't tell me what you're going to do, tell me how you're going to pay for it."
That is the truth! Especially now, Congress certainly is not working for the people. And if more corporations and billionaires were taxed like the middle class, there would be a lot more money to go to programs that the people need. Clean energy, more electric vehicles, that have a long range, Feeding children that are starving in the United States, and much more! Take care
@@kenr4709 A careful look at the IRS numbers will reveal that the upper 10% of wage earners account for more of the total federal tax revenue than the other 90% put together.
The more you make, the more that you pay in taxes. The next time that you do your taxes, grab a second form and see what the numbers look like if you double your taxable income. You will find that the "Tax Due" MORE than doubles.
Once you reach the point where your Itemized Deductions are greater than your Standard Deduction, a whole new world opens up. Now you can work at reducing your taxable income by spending money or losing money. This is why the very rich start charitable foundations and buy into iffy businesses.
Also, always remember that if your "refund" is more than your "Tax Withheld" , it's not a "refund", it's a welfare check that the rest of us paid for. That money is in your pocket, not feeding the hungry.
SOLUTION:
Ditch our Graduated Income Tax for a Flat Tax. A Standard Deduction and one tax rate. Period.
No additional deductions. No "credits". No "pre-tax" anything.
Set the Standard Deduction at the nation-wide average annual income for a Minimum Wage worker, adjusted annually.
(Gross Income) - (Standard Deduction) X (Tax Rate). You can figure your taxes on a napkin while out for dinner.
If the subtracting the Standard Deduction from your Gross Income gives you a negative number, you're done. If you get a positive number, multiply it by the Tax Rate, subtract your Withholding, and mail the check.
A Refund is what you get when your Withholding is more than your Tax Due, and only for the difference between the two.
FWIW, I am NOT rich. According to Pew Research numbers, I'm a Solid 55-YO Middle-class salaried wage earner with an hourly-wage wife.
I just got home from the uss george h.w. Bush deployment. This is true. Its also true that potable water goes quick when there is 5000 people on board.
With nuclear power, powerful engines, and abilities like desalination, US carriers really are floating cities that can offer emergency support too.
Back in 60s/70s, we used exclusively distilling. Pretty high maintenance. If I remember, sounds like daily output of current system is approx X 2 CVA 66
Wonder if they still brominate. Yummy, yummy, bromine water.
@@rocksnot952 Bromine is relatively inert as far as chemicals go. Chlorine is corrosive, highly reactive, a strong oxidizing agent, and as a gas is deadly in low concentrations.
My guess is that they still Brominate and add the trace minerals back in. Chlorine is just not something really awesome to have lurking around in a shipboard environment.
What about Fluoride? Is that being added to onboard drinking water as it's proven to strengthen teeth and make them more resistant to decay.
@@Au60schild Fluoride doesn't clean out your GI tract and provide the wonderful flavor and color that bromine imparts. Also, fluoride in a form that is biocidal is VERY hard to handle.
A question I have is how are the byproducts of desalination disposed of ?
I tend to think that if people are dying of thirst they will drink it. In McFarland CA. The population was subjugated to drinking the ground water. Which was contaminated with pesticides. Now the population is given water that is 90+% decontaminated. Sparklets. Blythe CA is the same.
Reducing the cost of desalination...when its cheaper the better for the whole worlld...❤❤❤🇵🇭🇵🇭🇵🇭🇵🇭
Love this. I was on a cruise recently and i always wondered how did they constantly restock the water. love such content!!
the shot of the cruise ship seems out of context when they are ONLY talking about military vessels. I knew cruise ships had their own, perhaps they got it from the Navy
I just need to get desalination for my home. The ships can tank.
I put it like this as an ex sailor.. if the water desalinization or filtration doesn't work. The CREW DONT WORK.....PERIOD !!!!
find it funny that at 4:24, he says introduced in the 1980s while showing video from the 50s. i know it was a long time ago but not that long
Interesting!
That was my job on USS Intrepid from 1971-1974. was completely different then
Fantastic ❤️🙏👍
They can stand up for about 50 years
Bro the thumbnail of the video is showing us the opposite thing 😂
Perfect for my project....
They do it the same as every ship does, FFGs, DDGs, CGs, LPDs, LHDs and CVNs all do it the same way.😊
how about the waste that desalination produced where they go?
Only concentrate over board with biodegradable antiscallants. CIP cleaning to be done around every six months. Usage of citric acid, which is not harmfull and being diluted in the sea.
Hàng không Mẫu Hạm Mỹ nhìn khủng khiếp quá. Một dãy phố nổi trên biển rất tuyệt 🇺🇸👍
It doesn’t matter whether you approve of how American aircraft carriers look, or not. They are still among the most respected sources of American firepower in the world. Even more so when you include the capabilities of the rest of ships in their battle group.
I thought it was “Distillation” not Destillation 🤔
Let me tell you it seriously stinks when the evaps go down, you don't know what bad is until they are making bug juice with salt water.
Whooau, what an Invention, mind blowing.......
my Grandfather had a desalination unit in his old rudder boat, he was a fisherman in Wilhemshaven. 🤪😜🤪
All crew members are ESSENTIAL, NO MATTER WHAT THEIR "OCCUPATION" is. BUT I "DO" MARVEL at what it TAKES ,for one to be a "SKIPPER", OF THESE MOBILE CITIES.
Wonder the future like star trek 2009 when Kirk and Scotty trans warp beam to the Enterprise while at warp.. scotty was beam into a system like this in the future... I would guess its for drinking or other use! This video is amazing base on the present and future of our current reality! Amazing work done to make this happen!
Marvelous ! 😎
Now that I think about it, every household should have the ability to distill it's own water. Time to construct a still! I probably shouldn't wait until the day my family and I don't have potable water to drink to construct one.
With the advent of the Air Water Generator, it's now the right time to replace desalination with the former to be installed at the ship's roof deck; thus, they could certainly save energy.
It’s expensive…? Alright….that and everything else! Except this actually makes sense and helps people 🙃
This is awesome and can help us honor our water treaties with countries like Mexico! THANKS :)
Definitely the world's best water will come from our Ocean ❤
3:34 The Navy misspelled "separation".
I was on a carrier, but we never had water problems. When I was on a destroyer one of the two reverse osmosis fresh water makers stopped working. They didn't allow most of the crew to take a shower for almost 2 weeks. That was rough.
they should make this in mass production to save rivers from drying if and I think it should be hydrogen to take over fuel industry from fossil fuel.... electric is just too slow in charging and distance...
Water water everywhere and not a drop to drink
The rhyme of the ancient mariner
12:00
one small problem with desalination as a large scale water source
it's expensive
Not buying the Dioxin story. During the distillation process any Dioxin present would remain in the evaporator and be discharged over board. My dad was on a destroyer in WWII and he told me they also added minerals back into the potable water to help ensure the crew got necessary minerals to maintain their health. I am a submarine veteran and we also distilled water in much the same way.
Is their any jobs for this? I'm a plumber and this interests me to join the navy for this kind of work
Great video. How often do the semipermeable membranes and filters need to be replaced and at what cost? In science labs, RO systems and their ion exchange resins are very expensive to service and maintain.
I think all navy ships should do thermal distillation because maintenance is not needed.
So why isn’t this in Jackson Mississippi?
Is there water ration?
*When the plant fails*
Captain: *sign* I’m sorry to call you here but we need your help, the water control chip has given up the ghost, the chip is beyond repair and process is too difficult for a work around. Long story short, we’re running out of water. We estimate we have 3 months at most of drinking water, we located another vault nearby and marked it on your map, not a bad place to start. Look, just stay safe, ok.
Power is pretty plentiful on a nuclear carrier. And the reactor itself needs massive amounts of water to operate, so there is always plenty to spare. Water is usually not a problem on nuclear ships (or subs)
With properly maintained equipment and basic water conservation as drilled into us since boot camp, water should not be a problem on a US Navy ship of ANY type.
Sure it happens, but it should only be an issue if there was an equipment failure or a major loss of water. Excess capacity is designed into ships for exactly this reason.
Yeah I can imagine using the sea water for the future goodbye ocean life🤦🤦
I never knew how important water was until I found out how beer is made
Ito dapat ginagawa ng maynilad at manila water ng d na kumukulang ang supply ng tubig natin. FYI lahat po ng ocean going vessel ay ganon po process ang paggawa nila ng fresh water. Alam kong alam na ng maynilad at manila water to, kaso ayaw lang nila mag invest at malaki daw.
Solar desalination makes sense in the desert. All you have to do is pipe in Seawater, do the desalination dance, and there you go.
Old ones: evaporative distilling units. New ones: reverse osmosis plants.
This is a really difficult one....the same way a 30ft sailboat does?
It’s called freshwater generator, you evaporate seawater then condensate it. And a device called salinometer will test it’s salinity if it’s already safe to drink at a certain ppm. But usually it’s used on other uses other than drinking such as for cleaning, toilet water and more. It’s not that complicated as this video trying to explain 🤷🤷♂️
FYI, they don't waste fresh water to flush the toilets on Navy ships - they use seawater.
Why isnt the desalination plant not connected to the nuclear power plant that fuels the air craft carrier?
Aircraft carriers do not use reverse osmosis filters for desalinating seawater.
Ok so why not just make a ship that only desalinates ocean water while collecting drinking water? It could be used by military, private, or commercial vessels, or shipped to an area in crisis if needed.
This feature of How Aircraft Carriers Turn Seawater Into Fresh Drinking Water At Sea via Navy Productions youtube gives an illustrative glimpse and is knowledge stimulating to watch (especially with the reference to how the water supply of multiple other navy ships is interconnected with the fresh drinking water supply of some of the aircraft carriers referenced).
I'm just wondering how the heell that the aircraft carrier wont get fukt by a missile or something. in this day and age I would think there'd have some sort of small nuclear cell for propulsion and electronic weapons that is harder to hit like a swarm
If you are the Canadian Navy, you transform seawater into lead water
How did jet fuel get into the fresh water supply?
@@kellywilson8440 I was at ET on the USS Forrestal in 82. Our head, adjacent to our berthing, just beneath the 'bomb farm', was one of, if not the, only ones with fixed shower heads. So, we were rather popular.
When those showers were running, you could usually get a faint odor of fuel. We all used to joke that we were showering in JP5 (jet fuel). Mostly because there happened to be a JP5 pump station both fore and aft of us. Well, I rode that ship into the yards in 83, for the SLEP in Philly. For a part of that time, I was a supervisor for a section of the fire watch division. Which meant I dealt with the gas-free engineer a lot.
That gas-free engineer told us that, in the yards as they were taking the ship apart, they had found cracks in diesel fuel tanks that connected them to fresh water tanks. So, apparently, the fuel we smelt was for real, except it wasn't JP5, it was diesel. We really were showering in fuel.
@@brolinofvandar Roger all that brother , Showers and bug juice had fuel in it , Take care !
@@kellywilson8440 Speaking of bug juice, I found it very interesting when I learned that the exact same stuff, in a higher concentration with less water, was used to clean oil/grease off the deck plates down in the main spaces. So, the same thing I often drank with meals was also used as a degreaser.
@@kellywilson8440 Let's just say, I learned about the bug juice = degreaser first hand. Spent some time doing just that. Not by choice.
So, you were at Cecil Field for my last couple of years in. My last station was USS Vreeland at Mayport 84-86. I can remember driving a base truck to NAS Jax once or twice for a pickup, but I don't think I ever made it to Cecil for any reason.
Since you mentioned ground tanks leaking, I believe there were issues like that, only with ground water getting into the fuel, with the gas station that was within the Forrestal Village housing area in Great Lakes, IL in the late 70's. I know that I ended up with issues with the 76 Honda I had at the time, stalling because of water in the fuel. And that station had been my usual, given it was a couple of blocks from my apartment.
Interesting that the first family housing I had in the Navy was that Forrestal Village in Great Lakes. And, my first ship years later was the USS Forrestal.
@@brolinofvandar that cheap hot sauce found on the mess decks did a much better job removing corrosion from brass FF fittings and hose connections than it ever did making food taste better.
how do they make jet fuel from seawater, and purified water from seawater, but they cant get the jet fuel taste out of the purified water. wtf.
meh if you dont mind a little fuel smell in your water works great
Seawater is not endless
Yep
I thought we had a rising sea level problem.
Broad usage of reverse osmosis for potable water will depend upon economics. Much of current fresh water usage is based upon defacto zero cost water. An example would be a golf course in the desert; such a golf course could not to support the cost of the reverse osmosis fresh water required to maintain ~100 acres of grass. In the US, because of our system of historical water rights, major sources of fresh water are used to produce agricultural products; for many of these products, economic calculation would result in negative value added, i.e. the farmer would make more money selling the water rather than growing the crop. This video is touting reverse osmosis for fresh water without strong data of an example where such water is able to be competitive in a global market. I remain skeptical, that desalination of sea water is a solution to global shortage of fresh water.
Replacing the jet fighters by drones will reduce the aircraft carrier `s need for a large number of sailors .
Remove the air wing, and you will still have several thousand sailors on board just to run the ship. The Navy does not use much automation. Tasks are performed by trained sailors who can make decisions and don't require a full reboot to bring a system back online.
Drones actually have a larger support staff than jets at least for the Air Force. You also need pilots to fly them.
Lack of pilots within an aircraft gives you extra flexibility in your missions. Of course, your enemy can also hack your drones like Iran did in Afghanistan
Yeah, but it'll increase the number of nerds to look after, program, remote pilot, and fix any damaged drones. DO WE REALLY WANT MORE NERDS ON BOARD?!!!
Putting so many people’s lives at risk just to operate a power station at sea isn’t clever during warfare when the aircraft need refuelling anyway because they aren’t nuclear powered and the vessel needs restocking! Great in peacetime but disastrous in real naval warfare
@Stew72 The U.S. Navy has designed their onboard nuclear power plants to scram and lock down mechanically so that at even the deepest of depths the nuclear power plant(s) nor their fuel would be breached should their vessel sink. The power plants are located internally where they cannot be breached. So, no worries mate.The engineers are very smart in their design. A number of nuclear powered vessels have sunk with no risk.
Where does all the salt go? That's a problem.
Evaporators use a continuous low-temperature distillation process. The salt water feed has part of the water removed by distillation, and the rest goes back overboard as slightly saltier waste brine.
@@kevincrosby1760And that's not good in the long run.
lists ships..... 8 cruisers (shows a cruise ship)
That's fine and dandy to turn sea water into drinking water but for thirsty folks in the interior of the US where there is no salty ocean in our back yard and all our lakes and underground rivers drying up like Arizona, New Mexico, Utah, Nevada amongst other states how are we gonna get some water
Quit sending it to California. Seriously. The State of California gets most of its water (and electricity) from neighboring states.
U just have to start piping in sea water and desalinate
Wow
That's an old technology!!! Even power plant use sea water to their boilers. And use it to their steam turbine!!!!
Saya same thing over and over
So if all of that can be done to sea water making it safe, why are we having water issues again? 🤔 just asking
It's by design. Keep everyone afraid of this and that, thrusting different issues in the public face at the right times to manipulate public spending patterns.
some people don't have access to that technology or don't get to offered food/water.
the same reason most of the world get fed but still some are in hunger
Not accurate on how carriers produce potable water.
why dont the desalinated water is poured in dams
then let the dams and nature treat the desalinatted water
then dams transfer it to treatment plants do its thing
desalination plants just need to remove salt and send it to dams
Distillation using waste turbine steam is most efficient.
You need the clean water to feed the boilers to make the steam in the first place.
NO WATER, NO CREW! PERIOD!!
Badlands chugs the ocean*
Cruise ships 🎉🕺
Why do you sound like camodo gaming
Q: Do you think desalinization is the answer to water scarcity on Earth ? NO, but it is a step in the right direction. Who is going to pay for the network of ifastructure for distribution. And, current technology though effective and inproving all the time. And, these poor coutries have even poorer people living in them and having often annual average earnings in many cases less than $1,000 and run by dictators to boot. If we guestimate this technology to be at the level of Generation, say 2.0... The world is going to have to become way more peaceful. However, desalination will need to achieve about Generation 5 0r 6.0 first . And, become a giving people. Many dictators will have to be removed obviously first.
"POT- ugh-bull" water? Honestly? Please tell me you used a "robot" reader. The word is correctly pronounced "POW" (as in bow and arrow) followed by "tuh-bull". Sheesh, this is the 21st century.
tl;Dr - water filter. they use water filter
Drinking sea water you might experience kidney sfone
