Goodbye stars.

I wonder what kind of dreadful ecological effects this will have on nocturnal wildlife?

My first thoughts were that it sounds like the plot from a Bond movie, but jokes aside, this may be a good thing, essentially ‘free’ lighting at night for the area covered, i wonder how long it would take for the cost savings to match the cost of the satellites

The full moon already have effects on our behaviour (and the one other animals), a permanent and brighter one will make things worse.

Besides that, night illumination (depending on their wavelenghts) affects our sleeping, that artificial moon will have a blue filter?

I wonder what the impact will be on wildlife that depends on the hours of darkness?

This sounds disturbingly like a plot of supervillainy. We'll really be in the shit when this thing goes live, only for U.S. intelligence (or maybe MI6?) to discover that that's no moon -- it's a battle station!

Would be great if it works, could on net reduce emissions.
