Hmmm, interesting. I wonder if it would survive the -30s we get in the winter....? It's worth a try with a few things to test it out in our climate.
Personally, I have an old fridge (unplugged) in my garage that I store things in that don't freeze like pasta, salt, sugar, tea.......but now I'm going to add a few cans (wrapped in plastic lol) and see what happens. Thanks for the post!

Welcome PrepHer,
I dont know if it would survive that temp, so far the lowest is -19 c
Imo id stay away from plastic it will make condensation faster.
To get a fridge to my location would have been more of a pain than it was worth, distance to get it there and space it would take up, so this was the solution i came up with 😀

While I do not have near enough room to move as much food as I have, I do have a good quality deep cement water cystern that is in one of my outbuildings that I have put shelves into and can lift and lower things into, it will keep things remarkably cool even in summer heat and if done correctly, it will keep things very cold but not frozen in winter, I did the experments a number of years ago, and it made it though even the most bitter cold of the depth of winter..

Folks you have to have some kind of heat source ............. like the earth itself.
Don't put stuff in a fridge in the garage. It will freeze eventually.
The garage floor on the other hand is connected to the earth. Earth below the frost line is 15C or the like. If you put something on the garage floor and cover it with a well insulated box, it may just stay above freezing inside the box. Concrete allows heat to travel - a conductor. If you have a huge slab and a tiny box it may not work. You may need a bigger box so the spot in the center of the box will still hold enough of the earth's heat to stay above freezing.
Same thing with the cistern. Enough of it's surface is below the frost line where the temp is always stable, summer or winter.
