Affordable Desalination Timeline

How much longer will it be until "we" figure out how to desalinate ocean water to use efficiently for agriculture, pools, various water features, & topically-fighting wildfires by actually watering the dry areas?
Come on, Scientists! Do you jobs.

As soon as the cost of energy goes down
A breakthrough like cold fusion would make desalination ubiquitous
But you still have the problem of how that water reaches the interior of the country where most of the agriculture is. That’s a lot of pipes or trucks to move the water

The Arabian peninsula already does this.

Because they have basically free energy pouring out of the ground

You boil/heat water first then collect the steam/evaporate.
Let the steam/evaporate cool off and turn into water.
I would think you could build a solar boiler to cut down the heating costs.
Also with as much humidity we have in South Louisiana, you could possibly suck enough warm moist air and covert that into millions of gallons of fresh water.

pretty sure this is already invented, it's just not widely practiced

Once we lick cold fusion, we'll also probably have the weather machine.

Definitely already invented. Definitely widely practiced just not on that scale.

It is already being done but for now it has to be done in a combination purpose facility.
For example....
They are building data centers on coasts. They are using the heat gain from the data centers and dumping it into desalination plants. The additional energy required to finish the desalination process is very reasonable. The data center gets some cheap cooling and the desal plant gets some free energy.
They are doing similar concepts with coal power plants. Coal plants essentially have to dump about 60% of their energy derived from coal into something other than electricity production (the steam has to be cooled and condensed back into water to create enough PSI differential to get enough force on the turbines). This wasted energy is typically just released to atmosphere. They are building plants on coasts that use this waste heat for desalination plants.
There will be many more opportunities as people start letting engineers do their things.

As does Key West.
nobody has mentioned what do we do with the near toxic salt brines that result from this. Most ocean plants and animals are so accustomed to "salinity" being one thing that they don't do well when salty becomes saltier.
Take a look at the google earth shot of the Gulf of Kara Bogaz to see what happens where there's too much salt.

Can't we make some killer salt lakes for people to travel to & float in?
Salt our meats, margaritas, & more?
Send it all to DOTs for melting snow on roads?

The steam is water even before it cools off.

Cruise ships have been making their own clean water by desalination of sea water for years.
The heat from the engine is used to boil sea water that is condensed into fresh water.
Also, water is the most abundant renewable resource on Earth. Plenty of private water and sewer providers on the Northshore have been making clean water and providing sewerage service for decades.
Most of these scientific questions are driven by uniformed/uneducated journalists who are also pushing an environmentalist agenda.

I guess that is where all the salt went in Margaritaville.
