Astoundingly simple, totally elegant: Place a clay pot inside a larger clay pot and line the space between with sand. Dampen sand with water, cover with cloth. As water evaporates, the sand is cooled; basic thermodynamics. Result: Eggplants inside now last three weeks rather than three days, and a region that had no refrigeration now does. Inventor Mohammed Bah Abba wins this year’s Rolex Award for his pot-in-pot system (and can now, ironically, afford an electric fridge).
