@PawelK @h4890 @useless_idiot Oh a bug out shack. Solar panels are full of problems but as long as they are physically protected and can generate more power than is needed in the winter, they should work.

Batteries are going to be a pain in some way or another. I remember reading about the Nickel Iron battery in an Electrochemistry textbook and that they are used in subways with some of them lasting 30 or 40 years of active use.

The tradeoffs are price, energy density and availability. All that can be overlooked if one is serious and needs a battery to last.

About the internet terminals, there are inexpensive and good quality travel routers made in China that can run OpenWRT. The higher end travel routers can run Ubuntu.

I've used a travel router for around 9 years and it's the same one. Connecting to onions in a University lab with the ability to change things up. They are also small so it could be taken apart and it wouldn't be recognized as a router. So many things that it could do.
