In addition, environmentalists strongly believe that using sustainable resources can have a significant impact on decreasing carbon pollution and slowing down the rate of global warming 3. In contrast, the burning of fossil fuels emits carbon dioxide into the atmosphere, contributing to global warming 2. Generating electricity from sustainable sources is an eco-friendly way of producing power since it doesn't release any greenhouse gases. The global energy demand continues to rise, but the depletion of fossil fuels and the increasing cost of traditional energy sources, such as electricity, have led scientists to shift their focus toward renewable energy in recent years 1. The HNF exhibits an efficiency rate of approximately 1.78% with a minimum efficiency rate of 2.26%. The results indicate that the MWCNT-SWCNT/EO hybrid nanofluid significantly improves the thermal conductivity, thereby enhancing heat transfer. The research employs similarity variables to simplify the complex partial differential equations into ordinary differential equations and solves them using the Chebyshev collocation spectral method. Various properties, including solar thermal radiation, viscous dissipation, slippery velocity, and porous media, are assessed to determine the effectiveness of thermal transport in SPS. The study conducts theoretical experiments and simulations to evaluate the thermal conductivity and viscosity of the CNT-based HNF. The research implements the non-Newtonian Maxwell type and Cattaneo–Christov heat flux model in parabolic trough solar collectors used for ships. Additionally, a novel approach utilizing renewable energy and electromagnetic control is proposed to enhance the performance of SPS. The study focuses on improving the heat transfer efficiency in SPS by employing hybrid nanofluids (HNF) containing carbon nanotubes (CNTs). The aim of this research is to explore the use of solar-powered ships (SPS) as a means to reduce greenhouse gas emissions and fossil fuel dependency in the maritime industry.
