"One model is the North African zeer pot: two nested #clay pots separated by wet sand. As air moves across the surface, evaporation chills the inner pot enough to preserve vegetables for weeks... Using local clay and a ceramic 3D printer, the team built porous column modules packed with sand and water. Like a scaled-up zeer pot, air cools as it passes over the moist surface."
