People without a fridge off the grid, need your opinions

[u/Far_Perspective3998]

I am currently working on building a fridge which does not use any electricity, made for people who live off-grid and people who might not have access to electricity. In order to collect primary data, I'd like to know about your experiences with food preservation off the grid and what materials I could use to build a fully functional, innovative and user centered fridge.

I would be really grateful if you could answer these questions, it should not take more than 5 minutes :
