Review on Renewable Solar Satellite Power | Original Article
The new millennium has introduced increased pressure for finding new renewable energy sources. The exponential increase in population has led to the global crisis such as global warming, environmental pollution and change and rapid decrease of fossil reservoirs. Also the demand of electric power increases at a much higher pace than other energy demands as the world is industrialized and computerized. Under these circumstances, research has been carried out to look into the possibility of building a power station in space to transmit electricity to Earth by way of radio waves-the Solar Power Satellites. Solar Power Satellites (SPS) converts solar energy in to micro waves and sends that microwaves in to a beam to a receiving antenna on the Earth for conversion to ordinary electricity.SPS is a clean, large-scale, stable electric power source. One of the key technologies needed to enable the future feasibility of SPS is that of Microwave Wireless Power Transmission. WPT is based on the energy transfer capacity of microwave beam i.e. energy can be transmitted by a well-focused microwave beam. The whole content covers how the “SPS via WPT” can be come into action in future and its related researches how it can be improved and can be used practically on a large scale. The content covers its historical and theoretical background. Its recent technologies and researches of SPS and WPT-antennas and receivers. And then it covers the transmitter and receiver issues and answer for the space use. It also about its efficiency and its improvement measures. It also contains the environmental issues and solution to those issues.
