Green Pre-Selection 2026

This is an open-source, modular cooling vessel made from porous 3D-printed ceramics and low-impact materials like bamboo cellulose. It is designed to offer a low-energy, electricity-free cooling alternative for communities facing rising temperatures or lacking complex infrastructure. It works using evaporative cooling enhanced by ultrasonic vibrations, inspired by natural systems. The modular, open-source design minimizes waste and encourages local fabrication and repair.
