The promise of solar energy for sustainable development and space exploration
... a definition provided in 1968 by Peter Glaser, who introduced the concept of the solar power satellite, space-based solar power (SBSP) means deploying very large solar arrays into a continuously and intensely sunlit Earth orbit, collecting gigawatts...

Unlocking the NewSpace economy through space-based solar power
..., multiple organisations, nations and individuals have proposed and researched various possible solar power satellite (SPS) designs that tackle the rotation conundrum: the solar cells always need to see the Sun and the microwaves always need...

Sunshades in space could help alleviate Earth’s climate crisis
... energy crisis, O’Neill proposed the construction of space-based solar power satellites that would supply Earth with all the clean, cheap power it would ever require. These satellites would be built from lunar resources by a huge workforce of regular...

Our changing world and the mounting risk of a calamitous solar storm
... heats our planet and controls our climate. In creating a large magnetic shield system, we could also design-in solar power satellites that could beam back clean energy to Earth that could assist with the financing of the...

Defending Earth against cosmic hazards
... possible. A deployable magnetic system at the L-1 Lagrangian point coupled with a solar power satellite system might be able to provide a type of shielding that could also transmit solar energy back to Earth 24 hours a day, 365 days a year. Clearly...

Creating a viable cislunar economy
... energy is collected, converted to microwaves and beamed to Earth. One concept for a two giga-watt SSP satellite - called Solar Power Satellite (SPS) Alpha - was developed by John Mankins under contract to NASA. It is a very large object, measuring...
