Space-Based Solar Power
A power generation concept involving the deployment of large solar panel arrays in geostationary orbit, with the collected energy transmitted wirelessly to Earth via microwave or laser. The concept was first proposed by Peter Glaser in 1968.
Timeline (last 90 days)
The solar irradiance in orbit is approximately 8 times the peak value on the ground, and is unaffected by atmospheric absorption, day-night cycles, or weather, with a theoretical generation duration of up to 24 hours.
The microwave or laser transmission efficiency from orbit to ground in traditional SBSP schemes typically does not exceed 50%.
