I came into possession of some old solar panels so I made a solar-powered web server with a raspberry pi. It's been sitting in my garden for two months running continuously on sun/battery power.
Perhaps the continuous uptime is not surprising given the extreme weather in London this summer.
It's been running the nginx start page for most of that time, but I finally made a little zine site and hooked it up to the web.
