Introduction

Space-based solar power (SBSP) or Solar Power Satellites (SPS)

collecting almost limitless ‘clean’ solar power in the outer spacenearly all of the 1 000 used satellites are solar-poweredsince 1970s: research of the conceptplanned U. S., Japanese + also European prototypesInternational Academy of Astronautics (IAA):

in merely 20 a: working space-based solar energy platformin just 30 a: with enough energy being produced for the entire globe

feasible power in the amount of 220 W/m2

What do you think the connection is?

Humanity/Mankind needs . . .. . . Eelectric energyE which is:

long-term available,resource-saving,renewable/regenerative,efficient, as well asinexpensive, good value for money/cost-effective

for their technology.

History and Development I/II

Timeline1941: ISAAC ASIMOV’s SciFi short story Reason – space stationtransmits energy collected from the sun to various planets usingmicrowave beams1973: PETER GLASER is granted United States patent number3,781,647 for his method of transmitting power over longdistances using microwaves from a large (1 km2) antenna on thesatellite to a much larger one on the ground (rectenna)1978–81: U. S. Department of Energy (DoE) and NationalAeronautics and Space Administration (NASA) examine the SPSconcept extensively1994: U. S. Air Force conducts the Advanced PhotovoltaicExperiment



History and Development II/II

Timeline (continuation)

1998–present: Japan’s space agency begins developing a SpaceSolar Power System (SSPS)1999: NASA’s Space Solar Power Exploratory Research andTechnology Program (SERT) begins2003: European Space Agency (ESA) studies2007: U. S. Department of Defense (DoD)/Pentagon’s NationalSecurity Space Office (NSSO): report (2007) stating they intend tocollect solar energy from space for use on Earth2009: future SBSP partnerships and commitments by: PacificGas and Electric (PG&E) & Solaren, Mitsubishi Electric Corp. +IHI Corporation, Space Energy, Inc., and Japan AerospaceExploration Agency (JAXA)2010: European Aeronautic Defence and Space Company(EADS) Astrium announces SBSP plans

Effect of exter-nal conditions not affected highly affected

Effect of Earth’smovement almost no effect (≈ 99%) generation of energy

Costs only receiving stationsno energy storage required

costly real estate set-upsenergy storage essentially

Energy loss no weather, vacuum, no at-mosphere⇒ no loss

atmospheric hindrance⇒ distorted energy waves
