Abstract

This innovative project is designed to simultaneously generate electricity and produce freshwater in coastal regions, addressing two critical global challenges: energy scarcity and water shortages. The system begins by drawing seawater into specially designed vacuum chambers equipped with convex roofs. These roofs are engineered to concentrate sunlight efficiently, significantly lowering the water's boiling point and accelerating the evaporation process. As the seawater evaporates, the resulting steam is channeled through a series of helical pipes. These pipes are strategically fitted with curved mirrors that further focus solar energy onto the steam, increasing its thermal energy and raising its temperature to optimal levels. The enhanced steam is then directed into a high-pressure storage tank, where it is held under controlled conditions to maximize energy retention. From the high-pressure tank, the steam is transferred to a Stirling engine, a highly efficient heat engine that converts thermal energy into mechanical work. The mechanical energy generated by the Stirling engine is subsequently transformed into electricity, providing a reliable and sustainable power source for coastal communities. To ensure the system operates autonomously, a solar panel array is integrated into the design. This array powers all the system's auxiliary components, such as pumps and valves, while also storing any excess energy in a battery bank for use during periods of low sunlight. This dual-purpose system not only leverages solar energy to its fullest potential but also exemplifies a sustainable and efficient approach to resource generation in coastal areas. By combining advanced solar concentration techniques with innovative thermal and mechanical engineering, this project offers a scalable and environmentally friendly solution for electricity and freshwater production, making it a promising candidate for addressing the needs of water-stressed and energy-deficient regions worldwide
