New ‘Nescod’ Tech Cools Without Electricity Using Salt and Sun!
Researchers at King Abdullah University of Science and Technology have unveiled a game-changing cooling technology that works without electricity. The system, known as Nescod, uses ammonium nitrate and solar energy to create a powerful cooling effect through a natural heat-absorbing reaction.
In testing, temperatures dropped from 25°C to just 3.6°C within 20 minutes offering a promising alternative to traditional air conditioning systems that rely heavily on electricity. Even more impressive, the system resets itself using solar energy, allowing repeated cooling cycles without any power source.
As global temperatures rise and energy demand increases, innovations like this could reshape how cooling works especially in regions with limited or unreliable electricity. Experts believe this solution could be used in homes, food storage, and medical supply preservation.
If scaled successfully, Nescod could provide a low-cost, sustainable cooling option for millions worldwide.
