Forget AC, scientists create salt & water cooling system that works without electricity, keeps temperature near fridge levels for 15 hours

Salt and water AC: Saudi Arabian researchers have developed a novel cooling system, NESCOD, that utilizes ammonium nitrate's endothermic dissolution in water to achieve rapid temperature drops. This off-grid technology, powered by sunlight for regeneration, offers a sustainable solution for refrigeration needs in areas lacking reliable electricity, potentially preserving food and sensitive materials.
