Overview of innovation

This invention relates to a small-scale, ecologically friendly energy conversion system that generates electricity from ambient thermal energy. The system captures and stores heat from various natural and man-made sources, including sunlight, vehicle exhausts, power plants, industrial processes, and other waste heat streams, and converts it into usable electrical energy. Designed for household or small community use, the system provides a reliable electricity supply even in areas with limited or unstable grid access. It operates through a continuous conversion cycle, ensuring a steady generation of power from available thermal sources. By utilising readily available heat energy that would otherwise be wasted, the system contributes to energy efficiency, sustainability, and environmental conservation.
