A pot-in-pot refrigerator, clay pot cooler or zeer pot (Arabic: ????? ) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer earthenware pot, lined with wet sand, contains an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed Рthe evaporation of the outer liquid draws heat from the inner pot. The device can be used to cool any substance. This simple technology requires only a flow of relatively dry air and a source? ? of? ? water. 
Workshop? ?objectives
To design and construct a Zeer Pot relating the geometry and texture of the print to the climatic performance.
This workshop will be the occasion to learn how to use a Robot for Additive Manufacturing, How to prepare the soil based material, how to deal with the geometrical limitation of 3d Printing as well as engage? ?with? ?performance? ?driven? ?design. Givens In order to create a comparable range of design between the students and to fit the design within the quantity of earth of a single tank, you will have to frame your design on a initial primitive surface which? ?you? ?will? ?find? ?in? ?the? ?given? ?rhino? ?file.
The? ?inner? ?pot? ?will? ?be? ?given? ?to? ?you? ?upon? ?starting? ?the? ?workshop.
The? ?mission? ?of? ?the? ?workshop? ?consists? ?of? ?design? ?and? ?produce? ?the? ?outer? ?pot.
Students will have to base your design around a freedom to model +/-15 mm away from the primitive surface.
