Czech born physicist engineer peter glaser outlined the concept in a brief.
Solar power satellite.
Space based solar power satellites sps are large structures in space that convert solar energy captured as solar irradiation into a form of energy that is transmitted wirelessly wpt to any remote receiver station.
Solar power satellites sps converts solar energy in to micro waves and sends that microwaves in to a beam to a receiving antenna on the earth for conversion to ordinary electricity.
First demonstrated at llnl in 2002 and currently still under development there this laser would be about the size of a kitchen table and powerful enough to beam power to earth at an extremely high efficiency over 50 percent.
Space based solar power solar power satellite concept.
To make this possible the satellite s solar power beaming system employs a diode pumped alkali laser.
Of all the many spaceflight concepts nasa has studied the most enormous was the solar power satellite sps fleet.
Also provides some perspective on the cost savings achieved by using extraterrestrial materials in the construction of the satellite.
Solar power satellites is known by a variety of other names such as satellite power system space power.
Satellites would be space platforms the size of a small city deployed some 22 000 miles 35 405 kilometers above the equator in geosynchronous earth orbit geo.
