I saw this on facebook (it must be true 
) and have never seen/heard others talk about something like this. Anyone familiar with something like this for preserving fresh produce longer?
I saw a video a few years back of this. It seems legit. Here’s a web site (first result on duckduckgo for kenya green beans charcoal house). https://nation.africa/kenya/business/seeds-of-gold/our-charcoal-cooler-keeps-produce-fresh--1008712
