BLUFSpace-based solar power (SBSP), conceived in the 1960s, involves using satellites to harness solar energy for Earth. Technological and cost challenges have limited its progress.
- Satellites in GEO receive sunlight 99% of the year, enabling constant energy generation.
- Microwave transmission reduces atmospheric losses, proven in experiments.
- CASSIOPeiA and SPS-ALPHA feature large reflectors and collectors.
- SOLARIS is a European Space Agency SBSP initiative.
