SOLAR POWER SATELLITE

High intensity energy of sun can be capturedTransfer of stored SOLAR ENERGY from space

to the earth surface Wire less micro wave transmission

HISTORY

Nikola tesla in late 1890 poineer of induction techniques introduced world wireless system.

In 1940s ability to convert energy to microwave was developed.

In 1964 willam c.brown demonstrated a rectenna In 1999,NASA’S Space Solar Power Exploratory

Research and Technology was initiated. On nov 2,2012 china proposed space

collaboration with india .

GROUND BASE : SOLAR ENERGY IS STORED AND UTILIZED ON THE GROUNDSPACE BASED: SOLAR ENERGY IS STORED ON THE SPACE AND UTILIZED ON THE GROUND

TYPES OF WPS

GROUND BASED POWER TRANSMISSION

SPACE BASED SOLAR TRANSMISSION

WHY??????GROUND BASED

• Costly storage devices required

• Less intensity of light• Low out put• Waste heat is radiated it

cant be handled

SOLAR BASED

• No need of costly storage devices

• High intensity of light• 99% out put is obtained• Waste heat is handled into

space

CONSTRUCTION• It mainly consists of three parts For collecting solar power in space solar cell heat engine for transmitting power to earth microwave laser Receiving power on earth microwave antenna(rectenna)

SOLAR POWER SATELLITE Have proposed to collect solar energy in space and beam it down to the earth

Working parts1)Photovoltaic cell2)Reflecting thin mirror3)rectena

PHOTO VOLTAIC CELLIN SOLAR VOLTAIC CELL THE HIGH INTENSITY SOLAR LIGHT IS CONVERTED IN TO ELECTRIC ENERGYSIMILAR TO THE GROUND BASED TRANSMISSION

RECTENNA

• An antenna absorbing microwave energy from a transmitter and converting it into electric power.

• Micro waves of 2.4 GHz frequency are used to transmit power

• Diameter around 5km.• 95% of the beam is fall on the rectenna

ADVANTAGES

• Unlimited energy resource • Energy can be delivered any where in the

world• Zero fuel cost • Zero carbon dioxide emission • Most efficiently collected In space only• High energy out put

Time to innovate

• Future generation of electricityFrom LIGHTING and THUNDRINGFrom TIDAL ENERGYFrom WATER ENERGY(BUOYANCY FORCE)

CONCLUSION

• Our resources are very limited and less effective so we need to find latest and alternative methods to generate power in which this solar satellite can be an evolution
