Yeah, without electricity a lot of a lot of things are very difficult.

I have solar panels, but they are primarially used for the fridge and freezer when the power is down.

As for mesh networks, I have a project that quickly sets up a mesh network from hardware that geeks have lying around the house (old laptops, raspberry pi boxes, etc.). It's very experimental, but it does work. With more contributions, it could work much better.

I'd like to combine the mesh with a lightning node and see how far I can get! I feel like if I can transfer money around, even if it is just in my local community, without the internet, that would be amazing.
