  1. Wireless Power Transmission ANKIT KUMAR B.TECH(ECE) 4th sem roll-90210411339

  2. Wireless Power Transmission Optionsfor Space Solar Power • Far Term Space Systems to beam power to Earth • Radio-Wave WPT System • Light-Wave Systems • Near term Technology Flight Demonstrations • Model System Concept 1A: 100 kWe satellite • Model System Concept 1B: 10 kWe lunar system

  3. Global Power Consumption Remote Sensing of Current Global Power Consumption:A Composite Satellite Photograph of the Earth at Night

  4. Initial Photovoltaic / Microwave SPSGEO Sun Tower Conceptual Design • “Sun-Tower” Design based on NASA Fresh Look Study • Transmitter Diameter: 500 meters • Vertical “Backbone” Length: 15.3 km (gravity gradient) • Identical Satellite Elements: 355 segments (solar arrays) • Autonomous Segment Ops: 1) Solar Electric Propulsion from Low Earth Orbit2) System Assembly in Gesostationary orbit • Large Rectenna Receivers: Power production on Earth

  5. Photovoltaic / Laser-Photovoltaic SPSGEO Sun Tower-Like Concept Lasers and Optics 8 Ion Thrusters Solar Panel Segment Dimensions: 260 m x 36 m PMAD Avionics • Full Sun Tower Portion • 1530 modules • 55 km long • Backbone can be eliminated Deployable Radiator Multiple beams

  7. Area of Significant Concern Intermediate Area Area of Significant Benefit WPT Wavelength Trade for SSP

  8. ISS with IEA Solar Panels Fully DeployedCurrent flight experience with large IEA reduces risk for near-term derivative applications

  9. MSC-1A: Lunar and Mars Power (LAMP) ApplicationLaser WPT to Photo-Voltaics on the moon or Mars

  10. North Pole (SEE BELOW) Moon’s Orbit • Sun Rays are Horizontal • at North & South Poles • NEVER shine into Craters • ALWAYS shine on Mountain South Pole (SEE BELOW) Solar Power Generation on Mountaintop Direct Communication Link Wireless Power Transmission for Rover Operations in Shadowed Craters Space Solar Power Technology Demonstration For Lunar Polar Applications • POSSIBLE ICE DEPOSITS • Craters are COLD: -300F (-200C) • Frost/Snow after Lunar Impacts • Good for Future Human Uses • Good for Rocket Propellants

  11. Conclusions • More reliable than ground based solar power • In order for SPS to become a reality it several things have to happen: • Government support • Cheaper launch prices • Involvement of the private sector

  12. THANK YOU
