Gravity batteries are so fucking cool
- I love the simplicity
  
  what simplicity? solid state is simplicity, a weight on a guide attached thru a cable and a bunch of gears to a generator/motor + the necessary safety features is the very antithesis of simplicity.
  
  Simplicity compared to the process of mining and refining rare earth minerals to make batteries.
