I've encountered several reports about a proposed space mirror that
would light up the Chinese city of Chengdu at night, replacing/reducing
their need for ground-level lighting.  Details vary by source.

I'm a bit skeptical of the feasibility.  I don't see how a satellite
in a rather low orbit would effectively reflect sunlight to light up
a ground-level area at night.
