Always thought having this on a personal level instead of a massive bank of expensive batteries, for house use would be an interesting project.
Maybe it wouldn't work at all, but I imagine a large cylinder made from lead encased in mild steel.
That is in the basement, or corner of a property.
It's then raised with excess power - electrically.
A full roof of solar for a day = being able to raise this really heavy weight about a third of it's full range
Any time you need the energy you release the weight, it slowly comes back down producing electricity - which can be temporally stored and cleaned up in a small battery / Victron arrangement to power house use.
