The future of sustainable cooling is being built in the Saudi Desert

Summary

KAUST researchers are developing passive cooling solutions that use no electricity to address Saudi Arabia's high air conditioning electricity consumption. The technologies leverage nanotechnology, reflective materials, water evaporation, and advanced sensors to cool urban spaces, greenhouses, and buildings. One innovation involves nanotechnology that absorbs water from the air to cool electronics. Why it matters: These advancements are crucial for sustainable growth in hot climates, particularly for protecting solar panel efficiency and addressing rising global energy demands for cooling.
