Neat.

Eyeballing it and doing some simple math, it appears each locker is roughly 7kwh and maybe 4X the size of my 3.8kwh batteries. That's obviously no-go for a car, but for a household system that is completely competitive in most cases. Obviously the use cases are a bit different and so and so forth, but the simplicity, use of widely-available materials, lack of toxicity... probably very cheap when done at scale. Very interesting.
