Teenage scientists from Indore, India, developed Thermavault, a refrigeration unit that leverages salt-based endothermic reactions to function without electricity. This innovation addresses critical challenges in transporting medication to remote areas lacking reliable power, especially for vaccines. Their project, which won the 2025 Earth Prize, aims to reduce plastic waste, enhance energy equity, and provide effective cooling solutions. The students plan to utilize their $12,500 prize to produce 200 Thermavault units for hospitals, significantly improving access to temperature-sensitive healthcare supplies in underserved regions.
"Thermavault uses salt-based endothermic reactions to create an electricity-free refrigeration unit, solving problems like plastic waste, energy inequality, and inefficient cooling, especially for vaccines."
Dr. Pritesh Vyas stated, 'we struggle a lot' when delivering temperature-sensitive supplies to remote locations, making projects like Thermavault vital for proper healthcare access.
The trio of teenage scientists won the 2025 Earth Prize with a $12,500 award to build and distribute 200 Thermavault devices to hospitals.
Thermavault is a breakthrough that utilizes reusable and sustainable methods to keep medications cool, addressing the transportation challenges faced in remote areas.
