- The power transmission has nothing to do with this. An SPS sits in
- sunlight, reflects it just like the Moon or any other satellite: the
- metal/silicon/ceramic structure certainly isn't invisible! This goes
- whether the beam is visible or invisible, or even on or off. See the
- calculation above, done by me and corrected by Steve Willis.
