The present invention relates to the field of solar thermal systems, particularly to a cooking utensil designed for the steam-based preparation of idli, a traditional South Indian food. The cooking vessel is specifically designed to operate using solar energy. In this system, solar radiation is concentrated by a parabolic dish onto an evacuated idli pan. The evacuated idli pan is a hollow-shaped cooking vessel comprising a disc or cooking chamber in which the food is placed and steamed for cooking
This study investigates paraffin wax/Titanium Carbide–graphene nanocomposite phase change materials (NePCMs) for enhanced thermal management in photovoltaic-thermal (PVT) systems. The incorporation of TiC and graphene is expected to improve thermal conductivity, heat absorption, and thermal energy storage capacity. The developed nanocomposites can regulate PV panel temperature, enhance electrical and thermal efficiency, and promote efficient utilization of solar energy
This project explores biogas production from malt spent grain as an alternative and sustainable energy source for rural communities in Ethiopia. Waste malt bagasse will be collected from breweries and processed through anaerobic digestion using a low-cost plastic tank digester instead of a conventional fixed-dome digester. The approach aims to reduce biomass dependence, deforestation, indoor air pollution, and waste while producing renewable energy and nutrient-rich fertilizer
