Re: The silver lining
messing with the day/night cycle - unintended consequences follow
Lighting streets with lamps is one thing. Shining the sunlight onto an area 7/24 is not the same thing. You can turn a street lamp OFF. The satellite is a "one size fits all" kind of thing. You can't control it. It's ON whether you want it or not.
But I think it'd be a nice target for ground-based 'satellite killer' laser testing - mirror? Oh CRAP!
(oh and for this to work properly, the mirror would have to be the size of a city, something about energy density, etc.)
