What Would Have to Be True
What conditions must all hold for space-based solar power to supply grids competitively?
Chapter summary
six.
Key takeaways
- 1
Launch must fall to a few hundred dollars per kilogram or less; specific mass must reach about 10 kg/kW or less in flight hardware; space hardware must be mass-produced at a few dollars per watt or less; robotic assembly and servicing must work at kilometre scale; regulators must license beams and spectrum; and plants must operate reliably for decades.
- 2
In 2026 none is fully met; launch is closest to the trajectory needed, hardware cost furthest.
- 3
Setcoin's gates give a checklist for judging progress.
