Re: The solution is clear
Easy, roll into your nearest friendly local service station "Two Thousand triple A's and a rank sandwich please mate"
Sorted, surely this would be the most realistic situation, not triple A's of course, a standard sized battery.
Until you calculate the grid connection such a service station would need in order to keep that stock of batteries on hand, and charged. Then it become smuch less feasible, especially in urban areas.
A flow battery might work, where you just pump in/out some new electrolyte.
