Can you imagine the one in 25k mirrors that fails to line up properly perpetually aimed at your house every night? Now it might look kind of cool, not gonna lie, but could wreck your sleep cycle.

It would wreck a lot more than that. The ecosystem for one. Some animals rely on nocturnal hunting to survive. That would go away. And that's just one small example of why this a horrific idea.

Oh yeah, just look at the ecological disruption an eclipse briefly causes.

This could have a completely unforeseen impact on wildlife, flora and fauna as well as temperatures and weather. Not to mention adding another 100000 tons of eventual space junk and the fossil fuel and thermal pollution to have launched it all.

Honestly given the 18 meter size, one mirror would probably create the effect of slightly brighter moonlight across a town-sized area, so not a crazy spotlight. It would look like a little bright star.

I'm thinking they intend to focus a bunch of them nightly at solar farms.

GPT says a single satellite-- if all things were perfect and it could hold over a solar farm for four minutes each night (prolly dusk or predawn)-- it could create 441 kW×0.90×0.80×0.22≈70 kW ×4/60h≈4.7 kWh, or under one dollar's worth of electricity.

So this is still a proof of concept. They prolly want to triple the size of each mylar reflector and keep making improvements.

You aren't going to confuse me with your fancy math, it's a bad idea.
