Saudi Researchers Develop Electricity-Free Cooling System Using Salt and Sunlight

Researchers at King Abdullah University of Science and Technology in Saudi Arabia have developed NESCOD, a cooling system that uses ammonium nitrate's endothermic dissolution in water to rapidly lower temperatures without electricity. The system cools from about 25°C to near 3.6°C within 20 minutes and maintains temperatures below 15°C for over 15 hours. Powered by sunlight for regeneration, NESCOD offers a sustainable, off-grid refrigeration solution, potentially benefiting areas lacking reliable electricity and reducing cooling costs in regions like the US Sun Belt.
