Mohammed Bah Abba And His Pot-in-Pot

So what’s modern+green about a couple of terracotta pots? Nothing and everything. The oldest known African earthenware has been found in Nigeria, so that ain’t exactly new. What does brings it up-to-date is the incredibly simple application of two pots, one inside another. Fill the space between the two with moist sand, and you have a most ingenious fridge. (That’s very modern if you live in one of the 90% of villages that don’t have electricity.)
