Ingenious evaporative cooler built to cool camel’s milk in Somalia. I love the use of corrugated galvanized iron sheets and sisal sack fabric to create the airflow and cooling system.

The upper ends of the fabric overhang in a water trough that rings the top of the cooler. Capillary action causes the water to slowly trickle over the inner and outer surfaces. A small vent keeps the interior air circulating and wind guides or tunnels direct air flow over the exterior surfaces.
