at a guess the cost of transporting sea water to the mountains would be prohibitive to begin with. may as well spend the fuel cost on heating the water directly.

Well, that's why I said excess solar energy. Could work in certains regions where you have both mountains neat coasts like california in the US and the west coast in south america, where you find all you need: seawater, sunny places during summer and freezing cold temperatures in the mountains during winter.

>may as well spend the fuel cost on heating the water directly.
Reverse osmosis is cheaper and less energy intensirve than freeze desalination, and that uses a lot less energy than evaporation in terms of energy/electricity, but I guess boiling the water could still work...

yes, you could use the excess energy produced during off-peak hours to pump water to colder regions.
It'd be energy better spent than mining bitcoin, no doubt.

There's also the idea of using bulk cargo ships to load up with snow, or ice blocks, in the higher latitudes, and carry it southwards, delivering it as fresh water.
That might be even more efficient since, ya know, we do that with lots of bulk cargo already.

Ok faggots, I calculated it for you.
A 100MW solar PV plant can produce 200GWh of electrical energy per year and requires 500 acres.

Let's assume we need to get 1 million m3 of water to a mountain of height = 4km.
h = 4000 [m]
v = 1000000 [m3] = 1000000*1000.0 [litres of water = [kg-f]
1 kg-f = 9.8N
E = v * h * 9.8/1 = 39.2*10^12

So, we'd need approximately 40 TWh of energy.

40TWh/200GWh = 200
Two hundred 100MW PV plants = 500*200 = 100k acres = 156 square miles.

I didn't consider energy lost due to drag in pipelines and whatever else, but this seems doable to me? Google says "California generated 68,816 gigawatt-hours (GWh) of electricity from solar power in 2023"
Considering that you could get like 80% of that energy back as hydroelectric power during winter... Could be useful.

>>16298526
Here's a calculation for you, tap water costs about 2 buck per cubic meter, so you would have to get all of that power for less than 2 million dollars + that's just the consumer price, your production price would have to be more like 0.2 freedom marsk per cubic meter to be competitive with municipal water sources before delivery and processing and that has to include the maintenance for all the massive infrastructure you would need.

Are you retarded m8? You think fresh water supply is assured? Do you understand the point of water desalination, you retard? Do you know why would it be convenient to store eergy during summer and use it during winter?
Also, energy from PV farms costs like $30/MWh on average. That's $30 million per TWh, not too far from 2 million dollars, not really far from the price you gave, and that's not considering the fact that more than half of that energy can be recovered and sold during winter, when energy becomes more expensive (because of higher demand). AND you would also have fresh water during summer...

Think about it. You don't need to fill the while reservoit or use all the energy, you use the energy when convenient, and use the (stored or desalinated) water when you really need it...

>Just pump endless amounts of heavy ass water from sea level to the top of a mountain....that'll be an easy and low energy project.
We got a literal retard here folks. RETARD ALERT!

FWIW, a passive solar greenhouse at sea level next to the ocean is the most effective low energy way to desalinate sea water. You pump or allow salt water to flow into a large clear dome of some sort. The water is allowed to pool and as sun hits it and heats the greenhouse dome water evaporates and recondenses as pure H20 on the walls of the greenhouse where it drips down and is collected as pure man made rain. Please note you can use deep underground pipes to pump air through a heat exchanger aka "geo-thermal cooling". With minimal fans warm air can be pumped into pipes underground to capture the Earth's natural temperature of 55-60F. With this low cost cooling device we can speed up the process of condensation inside the dome.

Please note this is all super basic tech and forms of it have been practiced for thousands of years by humans. I claim credit for the current modern idea but must admit I didn't invent any of the science. Far from it actually. It's an atmospheric water generator powered by unlimited in flows of water from the ocean.

What he suggests is far cheaper because the sun heating up a greenhouse at sea level is basically free while pumping water up the side of a mountain is massively expensive.

Here's one key potential advantage of freeze desalination vs reverse osmosis: by freezing seawater to certain temps, you get to keep the salt and other stuff. Most if not all reverse osmosis plants dump it to the sea.

This is called "eutectic freeze crystallization", btw.

I also forgot to mention that reverse osmosis plants only generate like 40% of fresh water for every m3 they take.

No, my point is, the argument is so obvious that there is no way you don't realize how retarded your shit is
Icebergs take a lot of time to form. Their presence or absense affect geophysics. Wanting to melt them means having to deal with consequences of that. The comparison with oil or coal is completely retarded.
On the other hand, the whole society is alarmed that there might be serious droughts in certain areas of the world, yet some of those areas also use a lot of water to produce shit like avocados...
Meanwhile, energy companies are desperate to find ways to store electrical energy.
There is no point in doing in using icebergs or glaciers when you could literally produce ice and generate fresh water by moving seawater to the mountains. The problem then becomes the energy and the infrastructure and the money.
