A new era of desalination | FT Food Revolution
Вставка
- Опубліковано 10 лют 2024
- For decades it’s been hoped that seawater could be desalinated at scale, to provide drinking water and irrigate crops. But desalination plants still only provide a fraction of the world’s fresh water, largely because they’re expensive to build and use a lot of energy. But as the FT’s Gill Plimmer explains, advances in technology and green energy efficiency mean desalination is now becoming a more viable proposition.

Is the background music necessary?
Yes, the ADHD TikTok generation can't focus without it.

Somehow I doubt that they are anything even close to a majority fraction of FT channels audience.
i acutally like it lol
Green desalination can bring about not only a revolution in agriculture, but also reclaimed deserts, lithium, battery catalysts, and neo-forests.
Knowledge capital pays off again, and again.
Sundrop (near Port Augusta in South Australia ) also uses solar energy to evaporate moisture for their greenhouse
This already exists in Curaçao🇨🇼🇨🇼🇨🇼
The first desalination plant in the entire world since 1928.
The best water.
The main problem with desalination is Brine water waste (the residue). They dump it back into the sea. Countries around Persian Golf and Mediterranean Sea are doing this for the last 50 years. They almost killed everything in the sea. The environmental impact is very severe.
I wish they could reprocess the brine into sodium ion batteries.
Modern techniques would remove all of the brines for lithium, separate the creams for battery catalysts, and make hydrogen from the water, all using renewable energy.
Drinking water, farm reservoir service, and buried reserves should be accounted for, as well.
The Salton Sea extraction methods bode well for the industry.
That's rubbish. The waste pipe in the ocean at the Gold Coast is covered in coral.
What I never understood is why Brine isn't "pre-mixed" with sea water before released into the ocean. It's a matter of concentration as I understand it so diluting it by 10:1 should make it less of a problem. Is it just a matter of cost or am I missing something else?
One would think the brine would be useful in saltpans. Should be competitive salt enterprise if it gets extra salty water for free
Those brines should then be filtered or lithium and uranium both of which can be extracted from seawater... Those would give the whole process that much of an economic incentive to use and reuse those brines more effectively...
The process to desalination for agricultural is much easier than for the purity level for drinking water. Drinking water is not the problem its agriculture needs
Pretty certain this is just the start, the next step is also more greenhouses, often probably without using the sunlight directly but using growth lamps. Why ? Because weather is less predictable and because costs are coming down.... including of energy.
Nice graphics
Are their any good and eco friendly ideas on what to do with the salt?
24 Hrs Desalination Process is the efficiency factor in Energy Savings.
People often think and say "just use the seawater if it's rising to provide water for us all, remove the salt". Yeah, you have no idea how much energy is needed for that and the cost of investments in infrastructure required. Your water bills would skyrocket.
That is exactly what was said in the video.
Not if you generate it from renewable sources. Plenty of examples already doing it some mentioned in this video.
what do you want? expensive water is better than no water
Wave/current power seems to be the most sensible.
CAN"T HAPPEN SOON ENOUGH
Look up BG three energy you can change the structure of the water
If you are talking about the cost throughout your film how does the cost of 1 l water compare to other production methods? That is the most important question, and you don’t answer it once😂
In their defense, it probably depends heavily on the location / country
Offshore nuclear plants…what could possibly go wrong…
The graphics for this video are astounding, but the sound effects are a little distracting. Just take it down a notch.
Where will all the salt extracted from desalination go? Releasing that back in the water wouldn’t harm the environment and sea life?
Well FT like always obfuscate the most harmful part. The desalination industry has kill everything in the sea from Great barrier rife to smallest fish in the Persian Golf. It is the most harmful industry ever existed.
Tossing the salt back into the sea is doable under certain circumstances as the amount of salt being added is tiny compared to the size of the sea.
The issue is people try to skimp on the cost of this and try to directly dump it back into the sea causing dead zones of high salinity around the dump pipes.
You have to basically spread out the dump zones across a massive area so that the amount of salt brine in any particular area is non noticeable. Some plants do this but it is much much more expensive
@@AH-fm7rj interesting… you got any source I can read up more on this?
@@inigomontoya4109 the problem with brine water is that it doesn’t mix with sea water as its density much higher. It goes to the bottom of the sea and creates a super salty layer. This kills all the vegetation on the sea floor and hence the food source of many fish types.
@@venesto there are articles about persian gulf. Search it.
wow
No mention about the Israeli innovation in desalination. They say they use new membrane technology revolutionizing the energy need. But what's the deal? Is it just hype, I don't know the details?
However, more energy is needed, desalination will help.
We have better and more friendly solutions available
This video provided no new information.
Not sustainable in the long term
Desalination isn’t particularly expensive for domestic use. For industrial and agricultural use it is too expensive. If domestic water wasn't used to subsidize industrial and agricultural use it would be far cheaper.
It’s strange to hear about desalination narrated by Nan 😂
Change voice please 🥺
I agree, but women dominate voting and laws are biased towards them like custody, support, employment and healthcare. As they control the ballot box, they get the office jobs.
@@vsstdtbs3705wth does this have to do with a bad voice acyor
Desalination is terrible for sea life especially if not site correctly. Desalination in a bay will destroy the marine ecosystems.
Really? The only person to do the voice over was drunk Judi Dench?
The elites of the world should focus on the space-based solar panel technology development, because it could make desalination even cheaper
The planet is fkd
Nice voice 😂
Pretty sure it's not AI, which is refreshing for an infographics piece like this.
Your voice isn't goo I'm leaving
crock of crap.....
Omg the voice actor is not good at all. Please change!
