Deutsche Aerospace Laser Global Solar Energy Concept (GSEK) Concept: GEO-based laser transmission to desert ground station for European power needs Key Features: Diode pumped laser Reception area in Sahara region with muhi-band gap cells for both solar and laser power production Suggestor/Source: Johan Spies Discussion MBB/Deutsche Aerospace proposed a laser/GEO system to provide European power needs in the next century. The reference paper describes their proposal for a 1 MW demonstration mission in support of the larger GEO laser system contemplated.
