Impractical in the sense of, if you have a motor or a steam engine or water power, just use basic counterweight, but if you don’t have that power, this is lower power.
... and now I’m wondering if I built the geology well enough to have sufficient zinc for battery piles. (I don’t think I did, and I won’t retcon that, because there are DAMN good reasons Galantier has the geology it has.)
Still really expensive, though.
I made this decision, I have to live with it.
