How do you charge that small battery? Going to the powerplant with it doesn't seem like a good answer.

I don’t know if you saw my edit, but in my case, it’s charged by either a portable solar panel or (optimally) home solar panels.

In the not so distant past there were plans for neighborhood scale nuclear reactors. That would go a long way towards distribution, redundancy, and scale issues.
