I think this company intentionally ignored discussing how battery storage has made solar energy a much more effective and viable solution.
And also cheaper than launching stuff into space. This may have been approved but that's a long ways off from actual viability.
Never mind that, they're ignoring light bulbs for the S&R stuff.

(Why, of all the things, would someone use a fire as their example for this? Fire is famously a light source. Also, famously, smoke is a thing that blocks out light from above).
