EMERGING TECHNOLOGIES
• Fuel cell• Small hydro resources • Hydrogen resources• Alcohol energy• Nuclear fusion• Power from satellite station
4
SPACE SOLAR POWER
• CONCEPT OF COLLECTING SOLAR POWER IN SPACE
• COLLECTED ENERGY CONVERTED INTO RADIATION
• TRANSMITTED TO EARTH STATION• CONVERTED TO AC FOR TERRESTIAL USE
5
BASIC COMPONENTS
A huge solar collector typically made of solar cells
DC to microwave conversion through magnetron
Microwave transmitting antenna, aimed at earth where rectennas are placed
6
How it works??

SPACETENNA : (Antenna on Satellite)
Transmitting antenna on horizontal surface, that faces the earth and carry solar array
Produce microwave(2.45GHz) and transmitted to atmosphere
It has a square shape with dimension 132m by 132m
About 2.6 million antenna on spacetenna
8
RECTENNA(Rectifying Antenna)
• Receives microwave of frequency 2.45GHz from transmitter
• With 85% efficiency• Diameter is about 5 KM• 95% of the beam will fall on the rectenna

SATELLITE POWER SYSTEM
ADVANTAGE: Unlimited energy source Unlike coal and nuclear fuels SPS
does not require mining operation Energy delivery anywhere in the
world Zero fuel cost Zero emission of CO2 and other
hazardous waste Efficient collection of solar
radiation Will not prone to the threat of
terrorist like nuclear power plant
DISADVANTAGE: Storage of electricity during off
peak demand hour Frequency of beamed radiation is
planned to be at 2.45GHz and this frequency is used by communication satellite also
Massive structure High initial cost and much time for
construction Requires a network of hundred of
satellite Size of spacetenna and rectenna
