Desalination won’t end water shortage
Re “Scrap high-speed rail” (Letters, Dec. 28): Don Anderson’s letter advocates scraping the bullet train and using the money for desalination plants in Southern California.
Our water problems have been caused by drought, which is a symptom of global warming. One of the causes of global warming is our dependence on burning fuel for transportation.
Desalination would exacerbate the problem. It takes 1,500 kilowatt-hours to produce a million gallons of desalinated water. That’s a lot of carbon being put into the atmosphere.
The solution to global warming isn’t to make more air conditioners, and the solution to our water problems isn’t to make costly water. We do need dependable, efficient, clean, public transportation in our rural areas and cities, and we need to be responsible when we travel.

Desal plants are proven. The Israelis are even selling excess water to their neighbors.
In addition to desal plants, Southern California needs generator-powered pumps to supply seawater to fire hydrants during emergencies.
Also, Los Angeles County should buy a massive fleet of used fire trucks to be stationed in endangered areas during fire threats.
To top it off, the state should create a program to outfit swimming pools with generator-powered water pumps.
Those are just off the top of my head.
the ticket is to use digital twins of small modular desalintaion plants paired with a digital twin of a gigapress inside an ai factory to produce the skill to make a desalination plant that will work independently or in concert and can fit in a truck or a rocket ship.
and then set up the manufacturing plant and desalinate seawater for $200@acre foot.
Fairytale alert.
You’re welcome. This is from Wikipedia (hadn’t checked in a while). Right in line with my numbers:
“In 2012, cost averaged $0.75 per cubic meter. By 2022, that had declined (before inflation) to $0.41.”
(a cubic meter is 256 gallons)
The current costs to Israel is $0.50/1000 litres.
With new technology coming around, it will be less than this, when you count for inflation, in the near future.
“Our water problems have been caused by drought, which is a symptom of global warming.“
You know floods are caused by global warming too.

So is snow in Florida.
So is pleasant, nice weather.

So are earthquakes.
Thank you....
The idea is not to use desalination as the main source of water, but to use it to mitigate short fall of supply.
California could make a ton of cash on Utah and Arizona and Nevada if they ever got around to making desalination plants a reality and building pipelines to these states.
New technology reduces costs and chemicals in desalination
Tried to get into that website—impossible without giving an arm and your left leg. No. Sites are desperate for information and revenue, but in my opinion they are doing it wrong.
The internet milieu is rapidly changing, sites are looking for ways to stay relevant and make money. They seem to not know what is in their best interests.
tow that iceberg the size of Delaware up and park it off the coast
To be fair, California murders its own citizens.
We could ask the murdered ones who got burned to death in the Palisades fires like the Hamas October 7th victims, but they're dead.
Drought? There was record rainfall a couple years ago. They let almost all of it run out to the sea for the sake of an irrelevant little bait fish. Desalination is a good idea but just building reservoirs...in short, doing the exact opposite of what Gavin Newsome has done by removing several dams....and containing rainwater and snow melt is what California desperately needs.
I honestly thought this was The Bee. It’s hard to tell anymore.
Desalination costs $1000 per acre foot. That’s $9 billion for the nine million acre feet used by all Californians for all purposes besides agriculture.
Close enough. It’s the Sacramento Bee.
They are even developing powerless desalination, using the same kind of osmosis as kidney dialysis machines.
Huh? Wouldn’t that depend on how cheaply it could be done?
Unless there’s a shortage of sea water I don’t know about..
CA has plenty of water. Their greater priority is to get rid of humans.
