Culturally this is never gonna happen, obviously.
Especially since it’s not necessary.
Energy storage tech is only barely in its infancy since fossil fuel corps have stood on its neck for so long.
It’s a really weird take to insist that batteries can’t work when we’ve barely even tried. It’s like the 2 year old saying it’s impossible because he’s been trying to stick the star through the circle hole, and that we should just be happy with stars not being in the box.
Ecologically damaging like lithium is still a case of star in circle hole: we’re only just scratching the surface of grid scale energy storage.

I want to see more stuff like grid scale flywheel energy storage. Dead simple tech and if it can live power by even 6 hourait's immediately useful, 24 and that's 90% of that you need

It takes a 260kg flywheel with all its mass at the edge spinning at mach 0.5 to store 1kWh.
If you want simple, build a carnot battery. It’ll be half as efficient, but far more compact and long lasting.

Many battery tech are dead simple. It is a rolled layer of specific materials at precise thickness but really not rocket science, especially when you are not concerned about per kg efficiency. Flywheels are much more complicated, requiring well maintained mechanics, a motor and a dynamo.
