CHANDRAKANT RATH 0501213107

INTRODUCTION The concept of a large SPS that would be placed in

geostationary orbit was invented by Peter Glaser in 1968 SOLAR POWER SATELLITES convert solar energy into

electrical energy and then to microwaves and send them as a beam to a receiving antenna on the Earth for conversion to ordinary electricity. It is otherwise called as Satellite Power System, Space Power Station, Solar Power Station etc.

WHY SPS ?  Limited renewable energy sources  Global warming due to nuclear and thermal power

plants.

 No waste products by sps.  24*7 power generation.  More energy generation.

WIRELESS POWER TRANSMISSION .

ADVANTAGES  FULL SOLAR RADIATION IS AVAILABLE ALL THE TIME.  5 TIMES MORE ENERGY GENERATION.  POWER CAN BE DIRECTED TO ANY POINT ON THE

EARTH’S SURFACE.

 LOW MAINTAINANCE DUE TO ZERO GRAVITY AND HIGH

VACCUM CONDITION.

 NO INTERRUPTION DUE TO DARKNESS, CLOUDS ETC..  NO FUEL, NO WASTE PRODUCTS, NO MOVING PARTS.

DISADVANTAGES  FUNCTION LESS DURING SOLAR ECLIPSES AND

SOLAR STORM.

 FREQUENCY OF RADIATION IS PLANNED TO 2.45 GHz

WHICH IS USED BY COMMUNICATION SATELLITES ALSO.

 MASSIVE STRUCTURE.  HIGH INITIAL INVESTMENTS  MORE TIME REQUIRED FOR CONSTRUCTION.

CONCLUSION  SPS WILL BE CENTRE OF ATTRACTION OF SPACE

AND ENERGY TECHNOLOGY IN THE COMING DECADES.  REDUCTION OF SIZE AND WEIGHT OF

INDIVIDUAL ELEMENTS IN THE SPACE SECTION OF SPS.  MORE USAGE OF ELECTROMAGNETIC ENERGY.
