  3. In Brief…… • What is Solar Wind Power? • Need of Solar Wind Power? • Important terms • Working • Advantages • Disadvantages • Future Scope • Conclusion • Reference

  4. What is Solar Wind Power? • A method to produce Energy from the Solar wind. • It uses a specially designed Satellite known as dyson-harrop satellite . • A larger model, with a kilometer-long copper wire, could generate upward of a billion billion giga watts.

  5. Need of Solar Wind Power? • Increase in global energy demand. • Renewable resources are limited • Decrease in fossil fuels. • Increasing Environmental problems • Harmful Effects of nuclear power. • Low efficiency of solar panels. • Unavailability of enough wind.

  7. What is Solar Wind ? • a stream of charged particles ejected from the upper atmosphere of the Sun. • mostly consists of electrons and protons . • Creates Geomagnetic Storms, northern and southern lights.

  8. Solar particles interact with Earth's magnetosphere.

  9. Northern and southern lights

  10. Dyson Sphere • a hypothetical mega structure originally described by Freeman Dyson in "Search for Artificial Stellar Sources of Infrared Radiation" in Science. • a system of orbiting solar power satellites meant to completely encompass a star and capture most or all of its energy output. • Many variants – Dyson Swarm, Dyson Bubble, Dyson Shell

  11. Freeman Dyson

  12. THE DYSON-HARROP SATELLITE (DHS) • Invented by Brooks Harrop based on Dyson Sphere concept. • Consist of a long metal wire loop pointed at the sun. • 1-centimetre-wide copper wire 300 meters long, a receiver 2 meters wide and a sail 10 meters in diameter, sitting at roughly the same distance from the sun as the Earth, could generate 1.7 megawatts of power • 1-kilometre-long wire and a sail 8400 kilometers wide could generate roughly 1 billion billiongigawatts.

  14. Transmission • Micro Wave Power Transmission • Magnetron : electric current electromagnetic waves. • Antennas and Rectennas . • Two Types of Rectennas - Wire mesh reflector and Magic carpet. • Higher Efficiency

  15. MAGNETRON

  16. ADVANTAGES • Clean and Safe Energy source. • Produce large amount of power. • Unlimited Energy source. • Relatively cheap – Major portion of the system consist copper. • Can provide power at a rate that increase proportionally to the square of current through the main wire

  17. Disadvantages • Complexity in construction • Requires bigger satellites • Will have losses during transmission. • Size of antennas and rectennas. • Launch cost is high.

  18. Conclusion • Since it produces large amount of power losses can be neglected. • Step towards large scale renewable energy generation. • Futuristic energy source.

  19. “By 2050, even if we use every available energy resource we have: clean and dirty, conventional and alternative, solar, wind, geothermal, nuclear, coal, oil, and gas, the world will fall short of the energy we need. There is an answer: a power source that produces no carbon emissions … that can reach to most distant villages of the world, and can turn both countries into net energy and technology exporters.”“I am convinced that harvesting solar power in space can bring India and United States of America together in whole new ways. And I am certain that harvesting solar power in space can upgrade the living standard of the human race.”- A. P. J. Abdul Kalam THANK YOU…
