This porous, ceramic structure cools the air using the evaporative cooling effect already applied by ancient civilizations. In contrast to modern air conditioning, it does not rely on electricity. Its design was an attempt at providing a more sustainable alternative to air conditioning in hot and dry climates.

The individual modules are hollow and can be filled with water. Water is able to evaporate through the porous ceramic walls, creating the desired cooling effect. The modular structure is inspired by the lattice structures found in crystalline materials, thus maximizing the air circulation around the cooler. This modularity also provides the flexibility to adapt an evaporative cooler to individual needs.
