Which of the following IITs has developed a portable solar-powered cold storage device with 500 kg capacity for storing vegetables and fruits?

Correct option is D

The correct answer is (d) IIT Madras.
· IIT Madras developed a portable solar-powered cold storage device with a capacity of 500 kg specifically designed for storing perishable items such as vegetables and fruits. This innovation aims to help farmers, especially in rural and remote areas, by providing an efficient and sustainable solution to reduce post-harvest losses.
· The device uses solar energy to power its cooling system, making it eco-friendly and cost-effective. The cold storage unit is portable, allowing farmers to transport and use it conveniently wherever needed.
· The technology behind the storage system incorporates phase-change materials (PCMs), which help maintain low temperatures even when direct sunlight is unavailable, ensuring consistent cooling.
Information Booster:
· Solar-Powered Cold Storage: Utilizes solar panels for electricity generation, providing off-grid cooling solutions for rural communities.
· Phase-Change Materials (PCMs): These materials store thermal energy, allowing the cold storage unit to operate efficiently during non-sunny periods.
· Post-Harvest Loss Reduction: By extending the shelf life of produce, farmers can minimize losses and increase profits.
· Portable Design: The cold storage unit’s portability enhances flexibility, allowing farmers to move it as needed.
