In an inspiring example of innovation driven by necessity and eco-conscious thinking, three teenagers from Indore have developed an electricity-free refrigerator, providing a sustainable alternative for cooling in energy-scarce regions.
The young inventors—students from a local government school—crafted the fridge using affordable, eco-friendly materials based on evaporative cooling techniques. Their model operates without any electrical power, relying instead on basic scientific principles to keep food and medicines cool.
Designed primarily for rural and low-income communities, the fridge can preserve perishables for several days, making it especially useful in areas with irregular or no electricity supply. The trio was motivated by the challenges faced by farmers and small vendors in their neighborhoods, where food spoilage due to lack of refrigeration is a daily issue.
“We wanted to create something that could actually help people in villages and slums where refrigerators aren’t an option,” said one of the teen inventors. “This fridge doesn’t just save electricity—it saves lives.”
The innovation has caught the attention of local authorities and science institutions, with several organizations showing interest in scaling the model for wider use. Environmentalists have also praised the invention as a step toward green technology solutions in developing countries.
The teenagers are now preparing to showcase their fridge at national-level science fairs, and hope to secure support to mass-produce their invention and reach the communities that need it most.
