I'm sure this is not the case but a refrigerator can be made from two
clay pots, one smaller than the other, charcoal and a cloth top. The
smaller pot fits inside the larger one with charcoal (or sand) betwixt
them. Add water to the charcoal and cloth plus evaporation. I also doubt
that it would work in the steamy jungles. Just thought I'd toss that out
there.

char came from what happened during and after cooking (If wood is easy
to come by, you can make a lot of char in a 3-stone arrangement**. I
have seen one argument for an approach like HTC.*
