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. is a clean,
large-scale, stable electric power source. Solar Power
Satellites is known by a variety of other names such as
Satellite Power System, Space Power Station, Space Power System,
Solar Power Station, Space Solar Power Station
