I like Treehugger for coming up with great designs that could change a bit the world we are living in. One of their latest finds was a natural air conditioner that uses clay and evaporation.
As Treehugger noted : ” Thibault Faverie‘s Cold Pot is a natural and simple air conditioner that uses clay and the power of evaporation to cool down temperatures in a low-tech energy-efficient fashion. “
Coupled with more efficient houses and buildings – a solution that would tackle our energy and climate problems – this invention could curb the use of climate damaging A/C.
The designer noted on his blog :
Cold Pot is a terracotta pot inspired by natural system to gradually lower the air temperature through the process of evaporation. Based on the ‘bio air-conditioning’, the porous terracotta surface acts as a heat exchange; it absorbs water from the inside and sends it to the outer surface. On contact with air, the water evaporates.
The change from a liquid state to a gaseous one results in the cooling of the object and consequently the inner aluminum pipe, where air circulates.
