Common Misconceptions
What do people often get wrong about space solar power, in both directions?
Chapter summary
sceptics often overstate the safety and physics problems, and enthusiasts often understate the cost and scale problems.
Key takeaways
- 1
The physics of beaming power from orbit is well understood and has been demonstrated at small scale; beams can be designed to stay below public exposure limits outside the receiver.
- 2
But "the Sun always shines in space" does not make the power cheap: sunlight in geostationary orbit is only about six to eight times more useful per square metre of collector than sunlight on the ground (Chapter 9), and the efficiency chain loses more than four-fifths of the collected energy.
