How to Make a Pot in a Pot Refrigerator
In a community or situation without electricity, storage of food long-term can be tricky. One simple solution is to build your own pot-in-pot fridge, using basic pots, sand and water. An idea revived by Mohammed Bah Abba, this refrigerator is now being used by many farmers in warm climates who need to preserve their food for a longer time and keep the insects away.
Keeping the sand moist all the time enables evaporation to cool the produce kept inside the inner pot. This enables the storage of freshly grown vegetables to last much longer than usual in a hot climate. It is also great for using at a picnic or outdoor meal where there is no electricity outside but food or drinks need to be kept cool. Here is how to make your own.
