Give it a few years and I've got my hopes up for batteries.
The calculations showed the absurdity in gravity storage today, not batteries in the future.
Gravity just isn't a good store of energy relative to chemical and nuclear alternatives.
It's a simple method for storing energy but not an efficient method. That's why the human body uses ATP instead of a bunch of pebbles that get lifted to our heads and dropped to our perineum.
But hey, we'll always have Dams. And tidal generators are gaining momentum. They're basically gravity batteries.
