Sophistication of space-based solar power has been around since the late 1960s, but the concept has not gained sufficient traction due to cost and technological hurdles.
Can some of these problems now be solved?
If so, SBSP could become a vital part of the world’s transition away from fossil fuels to green energy.
The authors discuss several different types of solar energy harvesting techniques: direct solar power, photovoltaics, solar-thermal energy, and solar-electricity via ground-to-ground transmission.
Geostationary orbit is ideal for this technology as it can harvest energy from the sun and beam it back to collection points on Earth.
Many designs have been proposed since the first concept by Peter Glaser in 1968, according to the authors.
These include concepts such as CASSIOPEA, SPS-ALPHA, and others.
The authors also discuss the practical challenges and risks of performing such a large mission as well as
