So far, desalination has not been a useful solution to the problem. Companies have been trying to create useful desalination plants for decades. The current process is expensive, inefficient, slow and creates toxic residuals. For these reasons, the current technology does not scale up very well at all. So far, desalination has not been a useful solution to the problem.
This a really bad take. Seawater deal with RO is a marvel of efficiency, only 2-3 times above the thermodynamic limit of demixing water from salt. It does not really generate toxic waste like coal fired power plants, but does produce lots of brine with various organics (antiscalants, surfactants etc.) that are not that great. The key issue is water is very cheap from traditional sources (surface water and groundwater) and requires rather crude treatment to be usable, resulting in very low cost. Hence why desal is used in areas where they have no choice. If you don't have surface/ground water source or brackish water source you are doing seawater deal or leave the area....not many choices. At least RO is electrified so it can use renewables but that does not really solve the much higher cost...or issue of brine generation, with zld have a set of it's own issues costs....
Very good to know. Thank you for the updated education.
It generates all the waste associated with the electricity it uses, which is often from coal fired power plants...
Considering the area a desalination plant requires, fitting it with wind and solar would not pose a challenge.
With enough demand, enough money for R&D will show up to improve the technology.
But regardless the current costs, that did not stop Israel to source all their water from the sea from very early, as well as other countries have for regions where there isn't enough drinking water available.
In my country, it's used to supply our islands territories and even by some hotels for pool water.
And the problem with the brine has me scratching my head, as I've read sources where the process required chemical treatment of the water and others where it's stated the process is entirely physical.
and how much fossil fuel does Israel use to achieve this?
I think they went nuclear on their power grifld.
that's better than coal for sure
No argument on that
Thanks, ChatGPT
I am not using any form of AI or other assistance. I am just old and have a lot of experience writing. Have a look at my post history to see the consistency in my writing style, even when I'm ripping a conservative apart.
I realize I copy/pasted my last line to the beginning instead of cut/paste, so it looks absurd now that I look at it again. I will fix that now.
Okay fair, just flagged my brain for the repeated phrase at the beginning and end
When I re-read it after your comment, I could see why you thought that!
Would actually be kinda cool if the prevalence of chatgpt forced everyone to write in a more varied and interesting style to dodge the accusations :)
