Batteries need energy density for vehicles, even batteries for non electric cars.
Uhn, what if space and weight of batterires wasn't a problem, like for home ?
Why not try to engineer a battery, rechargeable, with very affordable price for high storage capability, using something like chemicals solutions in tanks, like water thanks or small plastic composite pools?
If there is a chemical combination, affordable for recharge batteires, able to recicle, able to use in non xspensive tanks. Periodically the tanks content would be removed for recicled, avoiding polution of suage.
