To keep the cold inside, the Thermavault has a metal box wrapped in special wool and rubber, which helps to insulate. Using it is simple: just pour salt into the box, add water, and stir — either by shaking or with a small gyroscope (陀螺仪). The mixture cools evenly, making it perfect for storing food or medicine without needing electricity.
The team improved their process through a wide range of testing, working closely with Professor Mobin Shaikh, a material sciences expert at IIT Indore. They experimented with 15 different salts, applying scientific laws and specific heat to perfect the design. Their careful research and testing physical models paid off, impressing expert advisors and members who supported their innovation.
Beyond its scientific brilliance, the Thermavault holds promise for off-grid living, disaster relief, and rural healthcare — places where reliable electricity isn’t a given. By offering an environmentally friendly way to preserve essentials, these young inventors are making a real impact.
