Three innovative teens have engineered a salt-powered refrigerator that operates without electricity, aiming to deploy 200 units in hospitals. This breakthrough eco-friendly cooling tech promises major impacts in remote and energy-limited healthcare settings.

Their salt-powered fridge design uses ammonium nitrate and water to create an endothermic reaction for cooling—no plug required. The three teens behind the salt-powered fridge, Akshat Mittal, Kushagra Agarwal, and Divyansh Agarwal, may spark a global energy rethink.
