1.INTRODUCTION Researchers were encouraged to use heat recovery systems or renewable energy sources as practical solutions by the ongoing escalation of environmental issues and the ongoing rise in the expense of traditional energy sources. Systems for recovering heat from specific applications are referred to as heat recovery systems [1–11], and this practise increases the effectiveness of the use of energy. On the other hand, geothermal, wind, biomass, and solar energy constitute a majority of renewable energy sources. Solar energy is a unique form of renewable energy source that may be used for a variety of purposes.
Solar cookers leverage solar energy for cooking and food preparation, offering an eco-friendly alternative to traditional cooking methods that rely on fossil fuels. Advancements in solar cooker design, including concentrating solar cookers and innovative heat storage systems, have enabled faster cooking times, improved temperature control, and enhanced cooking performance. Integration with intelligent control and monitoring systems allows for precise cooking control and ensures efficient energy utilization, promoting the adoption of solar cookers as sustainable cooking solutions.
The utilization of solar energy as a sustainable and renewable resource has gained significant attention in recent years. Solar devices, such as solar water heaters, solar distillers, solar cookers, and solar dryers, play a crucial role in harnessing solar energy for various practical applications. These devices offer environmentally friendly alternatives to conventional energy-intensive technologies, addressing critical challenges such as water heating, water purification, cooking, and drying.
