[Tech] A low-tech; low-energy capsule?

1. Stephane Bortzmeyer (stephane (a) sources.org)

This Web article describes a low-tech Web server, running only on
solar power (and which does not work when there are clouds).

https://solar.lowtechmagazine.com/2018/09/how-to-build-a-lowtech-website/

Gemini seems well-suited for this sort of tasks. Is there such a
solar-power-only capsule?

Has anyone tried porting one of the Python implementations to 
CircuitPython or MicroPython? 

A microcontroller-based Gemini server would be a good match for a solar powered capsule.

Just remembered there's work being done on embedded Rust so maybe the 
agate server running on ESP32?

No idea if SSL would work though.

You could run it on a Raspberry Pi, if that is low energy enough.

I'm not sure if Agate could run on an ESP32 and am not qualified to talk 
much about embedded Rust. But I think ESP-IDF has support for TLS, so if 
there is a Rust wrapper for that, it would probably not be a problem. It 
would maybe require to use a different TLS library, which is a feasible change.

The Raspbery Pi Zero could be a nice match. It's tiny, can do wifi and 
bluetooth (the W version of it) and can probably work well on solar power 
(or AAA rechargable batteries).
