ZEER is a 3D-printed, electricity-free refrigerator designed to combat food insecurity in off-grid communities. Crafted from locally sourced clay, it modernizes ancient cooling techniques through advanced computational design. The core innovation is its Gyroid structure — this complex geometry maximizes surface area while reducing material weight, making ZEER 2.5× more efficient than traditional evaporative coolers.
The system relies on passive evaporative cooling. The structure is filled with water which permeates the porous ceramic and evaporates on contact with warm air, absorbing heat from the internal chamber.
