A method for evaluating the heat rejection efficiency in a Lunar power plant consisting of a free-piston Stirling engine FPSE is proposed. The waste heat from the FPSE is absorbed by the refrigerant circulating in a closed pumped loop and then rejected through a radiator into space. The magnitude of the heat flux rejected through the radiator is determined by the temperature differenc... https://www.lightemupsequences.com/great-deal-RVCA-Womens-Day-DreamTops-in-Periwinkle-mega-pick/
