Desalination is expensive, but it’s not just about the desalination simply pumping water up hill is costly. Nevada averages 5,500 ft above sea level. Moving 1 acre foot of water up that high at 100% efficiency takes ~5.6 MWh and a single mid sized farm can use that much water hourly. Start talking 25 inches of water per year across millions of acres and you’ll need a lot of solar. Worse, commercial reverse osmosis de…

take a black pvc pipe,stick one end into seawatter,add destillation collection crevices and overflowholes,put the other end up high on a hill

That doesn’t work. There’s a pressure difference across a desalinization system, it doesn’t output high pressure water.

Then don't farm in Nevada?? Humans don't consume that much water and lot of it can be recycled.

Humans generally use negligible mounts of water, the only meaningful water shortages are based around agriculture.

So don’t do water intensive farming in Nevada?

Nevada is just an example South Dakota is only 2,200 feet above sea level, but now you need an extra long pipe causing its own issues.

The point is desalination isn’t some magic fix that makes everything ok. The remaining salt is probably the biggest issue.

No, but it is a whole lot easier close to the sea. Like most of UAEs cities are. The remaining salt, you could just pipe out in the ocean, if you go in some km towards a current and spread it out enough. Salt in the ocean is only a local problem, if it does not diffuse quickly enough.

And for deserts with a high altitude or that are more inland, no, desalination is probably not the solution.

Salt in the desalinated water not salt in the ocean.

That doesn’t work. There’s a pressure difference across a desalinization system, it doesn’t output high pressure water.

its desalination and pumping via destillation by sunlight. it works.

its basically a heat driven capillary system.

You can call it overpopulation, I call it underdesalination. There is lot's of sun there and lot's of seawater.

According to ChatGPT it takes at least 3 kWh to desalinate 1000l of salt-water. Following that math and its estimates on solar panels that would come down to 0.003 m^2 of solar panels per liters. UAE is about 83.6 billion m^2, lets assume half of that can be covered in solar panels, so that would be enough to desalinate 13 trillion liters of water. That sounds like it could be enough for a country like UAE by a facto…

So your reference is “According to ChatGPT”. Did you feel anything when typing this?

"5,500 ft above sea level"

What your talking about works on small hills near sea level, but runs into real physical limitations. It's also slow and thus vastly more expensive per acre foot than commercial systems.

The weather is not the problem. Overpopulation is. And it is a local problem, so limiting population elsewhere doesn't help.

That's acting like we don't literally trade resources globally to maintain our population level

We can do this because the overpopulation is not happening globally. If for example Ukraine and Russia had the same population growth than Africa and Middle East is having then there wouldn't be no grain available for Africa or Middle East. But there are limits to overpopulation and it is water.

This doesn't have to be true anymore. Not all "we have too many people" people believe we need to FORCE depopulation. We have strong reason to believe that simply giving people sex ed, ample forms of birth control, and women's rights leads to a self selection of fewer children. Every country that has done these things has seen its fertility drop. Personally the earth can easily, EASILY, support more than ten billion…

The devil is in the details here, and programs focused on contraceptives in developing nations have a very checkered recent history. > the earth can easily, EASILY, support more than ten billion humans if we stop being so damn stupid about resource utilization This is sort of what I'm driv…

You better give some references about this "checkered recent history" because for example the programs US had for Africa were removed by GWB in the beginning of century when there was still less then billion of people in Africa. Now there is close to twice as that and Africa is not able to feed itself because population is growing faster than its capacity to produce food.

Normally those who stand against birth control have some very clear political agenda to use the size of the population in their advantage.
