Space‐Based Solar Power
As an Opportunity for Strategic Security
Zitat Text-Seiten 7-8 / pdf-Seiten 10-11:
„Typical reference designs involved a satellite in geostationary orbit, several kilometers on a side, that used photovoltaic arrays to capture the sunlight, then convert it into radio frequencies of 2.45 or 5.8 GHz where atmospheric transmission is very high, that were then beamed toward a reference signal on the Earth at intensities approximately 1/6th of noon sunlight. The beam was then received by a rectifying antenna and converted into electricity for the grid, delivering 5‐10 gigawatts of electric power.“Spiegel-Bericht über PENTAGON-PLAN
