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
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
And you’d still need to make a saltwater lake somewhere uphill.
water tanks tho
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.
