Gyroscopic Solar Power Satellite with the New Thermal Conversion System and Superconductive Generator

Resumo

The analysis of solar energy conversion methods in the projects of solar power satellites (SPS) has been conducted and the problems restraining their implementation analysed. Therefore, the article provides grounds for using promising heat-resistant materials of carbonic nanocomposite and low-temperature superconductors in the scheme of solar energy conversion with the purpose of creating SPS projects of a new type with improved weight and size parameters and physical and technical characteristics. The difference between the gyroscopic solar power satellites (GSPSs) with the new thermal conversion system (TCS) and superconductive generator projects and the previous ones lies in the absence of steam and gas turbine plants, a thermal radiator and a system of direction to the sun. The results of assessment of their energy and weight and size parameters have been presented: the thermal efficiency of conversion by the helium as working fluid at concentration of the solar energy of 74 and by the water steam at 38 has made 85% and 62.7% respectively; the specific weight of the entire thermal conversion system has made 2.17 kg/kW and 2.61 kg/kW; its specific capacity – 12.3 and 6.79 kW/m², the specific weight of the GSPS with the new TCS and superconductive generator has made 0.46 and 0.38 kW/kg. The suggested principle of functioning may be used in space power plants, being based on planets and the Moon.
