Using evaporation to cool the air

Sustainability Aspects: This air conditioner only uses electricity for the fan to increase the air flow that is cooled not for the cooling itself

Cold pot

A porrous terracotta pot, 2 liter water and a small fan together cool the air from room temperature to about 10 degrees Celsius. The terra cotta absorbs water from a two liter reservoir on the inside which seeps through to the outer surface and then evaporates. In the process of the H2O turning from a liquid into a gas, the terracotta, and an aluminum pipe on the inside, dramatically cool down. And a quiet electric-powered fan on the inside circulates air past that cold pipe and out into the room.

Unfortunately the designer Thibault Faverie is not planning production. Anyone? Contact Thibault or built your own!
