Small perk of the iron-air battery (such as the largest battery in the world, being built in Maine, https://www.canarymedia.com/articles/long-duration-energy-storage/form-energy-set-to-build-worlds-biggest-battery-in-maine https://www.canarymedia.com/articles/long-duration-energy-st... ), is that it's also bulky & heavy, which is harder to steal! Other future imagining: a bunch of wrecked or old EV's being used for their battery capacity, buffering power from solar. Charge station of old cars holding juice for new ones.
