Interesting concept, more viable for remote locations are hand crank generators used even before WWII .... its still around today
A modern version receiver:
Pedal powered radio transceivers were common in the Australian outback on remote cattle stations where phones were not available.
A common use for these was by children attending the 'school of the Air' where children in remote locations used the radio to 'attend' classes.
With cheap solar power, I doubt there would be may of the pedal powered ones left. School of the Air still runs though.
Never saw a kerosene radio but we used to have a kerosene refrigerator
A crystal radio is the obvious choice where mains power is not available.
A main advantage is cranking is it runs without sunlight, doesn't require large batteries, if the user is generally still alive, s/he can make power. Having combined crank and solar cells in the unit too can't hurt, to take advantage of sunlight were it is.
Just in case that some one miss it , at the first post the link drives you to more detailed pictures about the Kerosene Radio .
The main page belongs to a Greek who does old radio restorations.
There are lots of info about old radios - museum - pictures etc.
If you click on the Greek text as default , and explore the panel at the left , you will see more pictures , and subjects .
ohh, now i remember! i have those, but just smaller and using petrol, not kerosene.
how about peltier device? can it be used as a charger?

Some time ago we made some experiments with a low-cost Peltier cell, the ones used into portable fridges.
I saw one of these fans

Someone in the USA even made an auto-powered pellet stove, but using some optimized thermoelectric cells.
