So now the the world is entering the second great depression, what are some things we can invest in? Water? Automobile parts for when the supply chains collapse? Guns and ammo?

Please respond

No, he's right. we actually are already having a global water crisis, it's just not hitting first world countries yet.

What water crisis?

Protip: There's even more water on the other side.

That's salt water. Go ahead and drink it. Also go fund the desalination plants as well. They're fucking expensive to run.

Put water collecting cisterns under your property in rainy environments. Then when the world goes full desert mode you can sell or keep as your own.

Also, drain blood from people you kill or who die.

What is solar powered desalination?
>>
>>1036048
Extremely slow, hard to maintain, and absolutely not viable on a large scale.

Desalination is extremely expensive to build, and very nearly cost-prohibitive to operate.

Chemical synthesis is only useful as a lab experiment and on a small scale.

There really is no option. The population needs to use less, or they'll start dying until we reach equilibrium with the carrying capacity of the Earth. Pro tip: Earth's carrying capacity isn't 7 fucking billion. It's nowhere near 7 billion.

Can't we just freeze the water, then remove the concentrated brine? Though this probably equivalent in expense. Hmm, maybe some sort of charged filter which allows the water to come in but keeps the salt out? Maybe learn how extremophiles specialized organelles keep osmotic balance?

We can do it. It'll be expensive, people will die/go to war etc. but its just a matter of time.

Buying power is great, as long as you still have a job. How many jobs don't rely on the easy credit environment?

honestly the best way I can think is to open desalination plants in areas that have shortages and have means to pay. This would of course help the crisis, economics is kewl sometimes
>>
>>1036098
earth's carrying capacity widely accepted to be 9 billion, so yeah not 7
>>
>>1036312
That's assuming cheap access to fossil fuels and no major climate changes, from fossil fuels.

Cheap fuel -> people can live where they otherwise wouldn't be able to, like the entire Southwest.

Climate change -> shit that used to grow will stop growing, or require more water and other resources to grow -> food prices go up and it becomes more scarce

Long term carrying capacity is nowhere near 9 billion, let alone 7. It's closer to 2.

>As water in the lake goes down, we just build deeper intakes
Good plan, right?
>>
>>1035403
Yes, but it cost tons of energy and chemicals (to get rid of anything biological or carbon based before it goes into the membranes) people want to use electricity for other things.
>>
>>1036098
I am a water engineer and agree with you, but we can also do like California now and have total recycling of sewage straight back into drinking water. Cheaper than desalination and can be made completely (for all practical purposes) safe.

Freezing the water would take even more energy, because you need to freeze seawater to about -20°C. Boiling it is no solution either, they only do that in Oman because the salt water outside Oman is too salt for 'reverse osmosis' which is a kind of filter like you mention, but it demands very high pressures and the water needs to be very clean before it goes into the system. Very expensive, but cheaper than the alternative. There have been some recent research where some Chinese scientists managed to remove like 10% of the salt from salt water in a fuel cell with microorganisms. And a American chemist managed to desalinate a little bit of water with a lot of soy oil heated to about 40°C. Those are the most promising new technologies. Saudi Arabia spends billions on research, but at the moment engineers that work with water like myself don't have much better than reverse osmosis. I imagine there could be a way to do it cheaper by vacuum because water boil at much lower temperature in less pressure, but I have not figured out how to actually do it in a economic way.

>We can do it. It'll be expensive, people will die/go to war etc. but its just a matter of time.
Which is a shame, it CAN be fixed already today, it's just very expensive. People should not have to die.

Nuclear powered multistage flash distillation is the future of desalination
>>
>>1035590
only because of the fucking global population
>>
>>1036716
Except everywhere that need lots of water (except California) will get bombed and the women and children murdered by America if they build a nuclear power plant. It so it is not a realistic alternative even though it is cheap and environmentally friendly. But reverse osmosis is still way cheaper than flash destilation.

I lived in Dubai once. We all had desalination plants and for Westerners, it doesn't break the bank at all to buy bottled water.

It's strange to me that the only place with a more malthusian bent than /pol/ is /biz/.

With contemporary crop yield numbers, even a severe global drought wouldn't significantly impact food prices. Perhaps luxury, water-intensive crops -- almonds, avocados, ect -- but the staple basics would be fine in industrialized countries.

The only real risk is that it will disproportionately impact developing economies with limited access to water to begin with, thus creating social unrest and global instability.

I hope you're right. Granted the United States does spend waaaay too much fucking water on retardedly water-intensive crops like almonds (looking at you, California). Fingers crossed that you're right.

Dubai is one of the richest places in the world.

Control global warming and it wont happen. Water shortage is triggered by droughts triggered by global warming.

there is no global water crisis

the middle east and africa will simply wither. problem solved

america has oil, canada has oil, the uk has oil, japan has oil, russia has oil, china has oil many countries in south america have oil

we will do fine without them

With global security with them. Hardly a problem solved.
>>
>>1036705
What about using normal osmosis but with solutes which are more easily removed than salt (though I am drawing a blank on such a solute. It would almost certainly have to artificial. Perhaps nano-crystals which self-assemble with addition of a regent (or some stimulus like electricity).)
>>
>>1037609

Syria with its population of 22 million would be a comfy fun exercise compared to a place going dry like India with its 1.3billion citizens
