INTRODUCTION
The new millennium has introduced increasedpressure for finding new renewable energy sources
Building a power station in space to transmit electricity to Earth by way of radio waves-the Solar Power Satellites.
Microwave Wireless Power Transmission
WHY SPS?
Environmental problems due to fossil fuels.
Overcome day & night effect and other factors such as clouds.
Overcome energy crisis..
SPS– THE BACKGROUND
Peter Glaser invented the concept of a large SPS.
Fresh look Study, SSP Concept Definition Study.
SSP Exploratory and Research Technology Program.
SPS- A GENERAL IDEA
It is located in the geosynchronous orbit.
Comparison between ordinary satellite.
Its operation.
About structure.
PRESENTATION NAMECompany Name
WIRELESS POWER TRANSMISSION
WPT system mainly three components are used.
In SPS different kind of WPT systems are used.

MICROWAVE POWERTRANSMISSION IN SPS
The conversion of direct power to microwave power.
The collection of the microwave energy and itsconversion into electrical energy at the earth’ssurface.
The key microwave components in a WPTsystem are the transmitter, beam control andrectenna.
MPT-TRANSMETER
The key requirement of a transmitter is its ability to convert dc power to RF power efficiently and radiate the power to a controlled manner with low `loss.
MPT-BEAM CONTROL
Retro directive beam control systems have been the preferred method of achieving accurate beam
pointing.
The SPS transmitter to provide a phase reference for forming and pointing the power beams.
A key system and safety aspect of WPT in its ability to control the power beam.
MPT- RECTENNA
Rectennas are highly efficient at converting microwave energy to electricity.
RF rectennas are used for several forms of wireless energy transfer
RECENTLY DEVELOPED MPT SYSTEMS
The Kyoto University developed a system called SPORTS.
Industrial companies of Japan , is an integrated unit called the Solar Power Radio Integrated Transmitter (SPRITZ),developed in 2000
MICROWAVES-ENVIRONMENTAL ISSUES
The atmospheric studies indicate that these problems are not significant , at least for the chosen microwave frequency .
Specific research over the years has been directed towards effects on birds, in particular.
SOLAR POWER SATELLITE

advantages
The power could be directed to any point on the earth’s surface.
No waste product .
No fuel required .
disadvantages
High cost and require much time for construction.
Radiation hazards associated with the system.
The entire structure is massive.
The SPS will be a central attraction of space andenergy technology in coming decades. .
conclusion
It is not a pollutant but more aptly, a manmade extension of the naturally generatedelectromagnetic spectrum that providesheat and light for our sustenance.
