I was given a solar-powered radio years ago, and it also had an inbuilt generator - if you wanted to wind the handle for an hour. It sat in a corner for years, but at my new house, I've finally found it to be useful. The bathroom has a heat-lamp / light / extraction fan combo, I just use the heat-lamp, it makes enough light, and it also powers the radio via its solar panel. So, ten years after getting this radio, it finally is in use.
