Planetary Power Web Concept: 4 or more large spacecraft in GEO providing a substantial percentage of global electricity needs Key Features: Consolidation and distribution of power produced on board or by satellites in LEO, MEO, GEO or trans-GEO Receive power from other space power collectors via laser transmission Transmit via laser to other system elements for power distribution/storage Able to transmit via Microwaves to terrestrial users via multiple beams. Able to transmit power via laser to multiple terrestrial users. Suggestor/Source: Gregg Maryniak Discussion This concept was developed after considering the Solar Disk and similar notions of what an "ultimate SSP system" in GEO might look like. This system is an extension of space solar power and power relay satellites The purpose of this system is to provide global electrical power distribution using power generated in Earth orbit or on the surface of the Earth (or Moon). Each of the large GEO stations can, in addition to serving as a very large SSP unit in its own right, relay power from a variety of spacecraft in lower or higher orbits (including eventual Lunar Power Systems) to terrestrial users, or to one or more of the adjacent large GEO stations. Advantages Disadvantages Links all space power assets to terrestrial grids and other markets Provides extensive distribution and load leveling capability Can provide space exploration and base power throughout Earth-Moon system and beyond Requires large-scale space construction expertise A follow-on after other Space Power systems have been implemented Assumes development of reliable dc-to-laser power conversion.
