Say Goodbye to Traditional Air Conditioning: Millions Are Turning to a Cheaper, Electricity-Free Cooling Solution

Key Points:
- Saudi researchers at King Abdullah University of Science and Technology (KAUST) have developed Nescod, a cooling system that operates without electricity, using ammonium nitrate and solar energy to provide sustainable cooling.
- Nescod leverages the endothermic dissolution of ammonium nitrate in water, which absorbs heat and can reduce temperatures from 25°C to 3.6°C within 20 minutes, making it significantly more effective than other salts.
- The system features a solar-powered regeneration cycle where solar energy evaporates water, allowing ammonium nitrate to crystallize and be reused continuously without external power.
- This technology offers a promising solution to reduce global energy consumption from air conditioning, which currently accounts for about 10% of electricity use worldwide, and could particularly benefit regions with limited or no access to electricity.
- Beyond cooling buildings, Nescod has potential applications in food preservation and storage of temperature-sensitive items, addressing critical needs in hot climates with scarce energy and water resources.
