Solarpunk technology

Ignore the fact that Tesla are involved. I'm quite excited for this era of energy storage that we're entering.

I'm not sure if any of you are/were anime fans, but do you Vash Stampede and Trigun? There were a bunch of giant sand batteries in there, that always stuck in my head.

Obviously, things didn't work out great for them, but a clean future requires clean storage and clean generation and the first step is storage for everyone.
