Obviously lithium-based batteries are going to be the best for energy density, but going to other materials makes a ton of sense for big installations (for buffering solar and wind, for example) that don’t ever move.

This is the first I’ve heard of iron batteries, though. I always figured we’d do sodium batteries for big installations since there’s so much of it just dissolved in the oceans.

And we're gonna be producing more by desalination if we want to have enough drinking water in the coming centuries.

Don't forget the plastic and chaos filters!
