A new era of desalination | FT Food Revolution

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.

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.

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.

Sundrop (near Port Augusta in South Australia ) also uses solar energy to evaporate moisture for their greenhouse

[paulcunningham]

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

[stickynorth]

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...

[autohmae]

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.

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.

[Dynasty]

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.

[jameslowellblakenship]

Wave/current power seems to be the most sensible.

[stefanoehrlein]

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😂

The graphics for this video are astounding, but the sound effects are a little distracting. Just take it down a notch.

[venesto]

Where will all the salt extracted from desalination go? Releasing that back in the water wouldn’t harm the environment and sea life?

[jeffevers]

Look up BG three energy you can change the structure of the water

[Vlaid]

Offshore nuclear plants…what could possibly go wrong…

[KatsuYoshiHIRANO]

However, more energy is needed, desalination will help.

This video provided no new information.

Desalination is terrible for sea life especially if not site correctly. Desalination in a bay will destroy the marine ecosystems.

[matthewhuszarik]

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.
