I'm assuming you understand that my statements have a implicit "from an economic pov" when I argue about the practicality of pumped hydro storage, and you're arguing that it is economical to do pumped hydro on a small sc

On the depth thing, I really only meant to mean you need lots and lots of water. You could have a shallow basis, and take over a huge area of land, or or smaller amount of land if you have deeper water. Deeper also allows for less evaporati

Pumped hydro needs to be truely massive scale, both in the amount of water (read: lots of depth AND surface area), and the height differential between the two reservoirs. To make it cost feasible we really need very favourable natural geogr

Perhaps. But this stuff does raise the minimum amount it takes to build, which in turn makes developers less likely to invest in building affordable housing.

As another top level comment stated, in a lot of circumstances you can make do with charging an EV from a normal outlet. The post was mostly about the challenges with regulations/codes. For the most part it was a plea for governments t

Sounds good, but just don't be surprised if this results in more expensive rents, and less affordable housing being built.
