SS, We too have a 12V thermoelectric cold box but it’s only really good for keeping beer cool. A bicycle driven alternator sounds like hard work, why not use wind power ?, it would complement your solar generation.
I remember seeing a picture of a wind generator made from an oil drum cut into vertically into two sails fixed between two plywood discs and mounted on a vertical shaft, like the rotating signs you used to see outside garages. One of the ply discs wes laminated and the edge was pulley shaped with a drive belt to the alternator fixed to a solid timber mounting frame.
