  • Patent number: 11828495
    Abstract: The present disclosure solves the problem of solar energy capture and storage for solar power generating devices. This power system does not rely on batteries to accomplish energy generation during nighttime operating hours or during cloudy days. Solar energy is collected in a chamber equipped with opposing parabolic mirrors and a gaseous medium. The solar energy collector traps the majority of incoming sunlight and, through the processes of thermal radiation, heat conduction, and heat convection, converts said sunlight into useable heat energy. The heated gaseous medium is pumped to a Stirling engine for the purpose of conversion to mechanical power.
