ABSTRACT A solar power satellite is a very large-area satellite in an appropriate orbit, which would function as an electric power plant in space. The satellite would consist of three main parts: a solar energy collector, to convert solar energy into dc electric power; a dc-to-microwave converter; and a large antenna array to beam the microwave power to the ground. For the production of 1 GW of dc power the solar collector would need to have an area of 10 km2, and would consist of either photovoltaic cells or solar thermal turbines. The dc-to-microwave converter could be realised as either a microwave tube system or as a semiconductor system, or as a combination of both. Download read more

ABSTRACT This paper mainly deal with the global climate change and the environmental problems due to the implementation of thunderstorm solar power satellites.The rapid increase in the global warming due to greenhouse effect need to be considered very much.So a team level planning is made to buildup a layer to safe guard us from these harmful radiations.This thunder storm power satellite is a concept made so as to consider the geological improvement of our climate through the space power or solar satellites and this paper also deals with the political,economical and various other aspects which could have impact by the implementation of the project.

ABSTRACT The lack of energy sources made man to move to space to meet his energy needs.But two factors makes it difficult, they are cost and environmental pollution.It requires a huge some of money to make any kind of energy producing source in space ,from the studies made so far the most easy method is the construction of a solar power station in space.Solar power satellites is highly bulk and costly.Another major problem for the concept of solar power satellites is the environmental pollution caused by the solar power satellite. In solar power satellites the transmission of power through atmosphere as micro waves forms an inevitable but it may result in various environmental problems part this paper mainly deals with the environmental pollution occurring while transferring the high read more

ABSTARCT Placing of large number of solar power satellites in space give a solution to the energy crisis faced by the world today.The concept of solar power satellites were  deeply studied by DOE(Us department of energy)and NASA in the late 1970s.It was again brushed by a recent NASA  mission names”Fresh Look Study” in 1995-97 and in 1998  by”Concept Definition Study”.many programs were started by a NASA as a preliminary step for the concept of Solar Power Satellites.Thus paper mainly deals with the current improvement in the studies regarding the wireless power transmission which plays a vital part in the concept so called Solar Power Satellites.

ABSTRACT Radio waves can benefit the welfare of humanity through other purposes than communications. Microwave power transmission (MPT) is one of the new technological frontiers. Solar power satellites (SPS) will provide a clean and limitless energy resource from space through this technique. This article answers the fundamental question of why we need to develop the SPS from a viewpoint of critical global issues for mankind. It then reviews SPS research, mainly in Japan, in the 1980s and 1990s. These efforts include two MPT rocket experiments; a microwave- driven airplane experiment; and MPT technology developments, concepts, and systems studies of the SPS. A summary of recent research committee activities on SPS and a road map of future SPS research plans in Japan concludes the read more

ABSTRACT The concept of the Solar Power Satellite energy system is to place giant satellites, covered with vast arrays of solar cells, in geosynchronous orbit 22,300 miles above the Earth’s equator. Each satellite will be illuminated by sunlight 24 hours a day for most of the year. Because of the 23″ tilt of the energy efforts. Consolidation of responsibility was completed when the Department of Energy was formed in 1977. The Department of Energy developed a comprehensive program that concentrated on four areas: 1) technical feasibility; 2) environmental impact; 3) societal impact; and 4) cost comparison. NASA was responsible for the technical studies and DOE retained responsibility for the others as well as overall program management. Funding for 3 years was $19.5 read more

ABSTRACT 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 read more
