All-iron flow batteries hold immense potential due to their use of cheap, abundant iron and safe, water-based electrolytes.

So it's a rust battery? Because that's what happens when iron gets watery. It rusts.

I mean if it works, that's great, I just find it funny.

This is getting out of hand, now they are refactoring batteries to use Rust too

Rust is designed to work at the hardware level.

And Rust is both secure and efficient, am I right?

No leaks either!
