To make solar power viable, we need a solution for overnight energy storage.
Batteries are complicated.
Do you know what isn’t? Water go up.

It’s fine for places that have a lot of water and hills
For places without water, what’s wrong with importing a bunch once? Evaporation suppressors exist to help with hotter climates.
You’re probably right about the hills. Building a water tower that can hold an entire lake seems inefficient.
How are you importing an entire lake?
Truck? 5G? Just let a tiny faucet run a long time? IDK.
from somewhere import lake
lake.flow()
It’s just that simple!
Use a very long hose.
You don’t really need huge volumes of water, a 5GW hydro storage proposal in Australia will require 38 gigalitres, or 0.038 cubic kilometres. At a depth of ten metres, that’s a 2km circle (or rather, two ~1.5km circular reservoirs).
Arizona uses ~8500 gigalitres a year to put that in comparison.
you can use saltwater for it though, doesn’t need to be fresh water or treated in any way, just a physical medium to make turbine go brrr
Machinery and saltwater generally don’t mix very well. And you’d still need to make a saltwater lake somewhere uphill.
yeah but in this case it’s just a pipe and a turbine it’s gotta make move
water tanks tho
Saltwater damages turbine blades very fast. Using saltwater would require some very different engineering for the turbine blades, which might not be worth the benefit of being able to use saltwater.
Turbines are precision machines. And if we’re talking utility scale installations here, we want an upper reservoir measured in thousands of cubic meters, not liters.
