- A tweet by Luke Parrish proposed an offshore solar plant that harvests sunlight reflected from kilometer-scale space mirrors in 10,000 km orbit, estimating an optimal ground footprint of ~100 km wide.  
- Channel participants debated the geopolitical feasibility, noting that any space-based sunlight redirection could be weaponized by simply curving the mirrors to concentrate energy, inviting international opposition.  
- Kanzure countered that international opposition is irrelevant if actors can launch and defend satellites unilaterally, and suggested the same technology could be used to block sunlight as a form of geoengineering to reduce global temperatures.  
- L29Ah observed that destroying such satellites is cheaper than deploying them, but the resulting orbital debris would likely trigger severe sanctions against any state or non-state actor attempting it.  
- Astronomers’ anticipated backlash was highlighted as another practical barrier, because large reflective satellites would interfere with ground-based optical observations.
