Startup Says It'll Use Huge Space Mirror to Sell Sunlight During Nighttime
Startup Says It'll Use Huge Space Mirror to Sell Sunlight During Nighttime
A unique startup claims it will soon let people buy spots of sunlight reflected with a giant satellite mirror.

Because that won’t fuck with nocturnal animals at all….
Who cares about the environment! We have investors to grift! Money to be made!
It won't actually work. So yes, this is just a grift until funding dries up.
In the demo, former SpaceX intern and startup cofounder Ben Nowack is shown using an app outside in the dark that seems to control the location of the company's sunlight-reflecting mirrors. As he selects the spot where he stands, the area around him is suddenly illuminated as if by stadium lights.
LMAO of course it’s a SpaceX intern’s idea.
Yeah, it's boring.
I want a Starliner intern to come up with something.
Btw, Starliner undocked the space station, set course back to earth and must have landed, uncrewed, 2 - 3 hours ago. That was the plan, at least.
Edit: Here it is after undocking the station, showing off it's glorious thrusters:
Dude, I read about it in a 1990 donald duck (true actually, +/- some years).
can I buy sunlight to point at someone I don't like for say, a month? no reason.
This. This I could get behind.
my neighbor ran a jackhammer for three months every day trying to build a pool. I say three months of no darkness at night is fair retribution.
You better hope you're not a customer's neighbor.
Ah yes, let’s redirect sunlight ONTO the Earth instead of away from it. Global warming isn’t real, after all.
/s
No way this doesn’t end poorly. I’m envisioning the SOL laser from Akira.
I imagined Mr Burns blocking out the sun, charging for sunlight.
Also I thought about who I would deliver middle of the night sunlight to, definitely not out of spite.
You mean the moon?
Hahahahah-
Wait... They're serious?
Does anyone really think this could actually work? A LEO satellite would have to be massive (>1 km) to reflect a significant amount of sunlight, and you'll need to put it waaay higher to avoid atmospheric drag. Not to mention the problem of the satellite only being above a given location for a few minutes a couple times a day.
This right here. Never mind the dystopian Mr. Burns style subscription based sunlight control bullshit that's inherent to the very idea. That's just to sucker in the investors who won't know any better. Not enough people are talking about this.
I guess they could try to put the thing into some kind of geosynchronous orbit, but essentially the surface area of their mirrors will have to be equivalent to the area on the ground they plan to illuminate in order to achieve "sunlight" levels of illumination. There's no way around that. So motherfuckers are going to start spouting off about "parabolic dishes" and "lenses" and shit any minute now. This is a red herring. No amount of optics can overcome the fact that the amount of light you can reflect will never be more than the amount of light that hits the mirror. Period. You cannot, now or ever, defy the laws of physics.
The International Space Station is basically the biggest thing we've ever managed to permanently put into orbit, yeah? And you can barely see it with the naked eye in the night sky, let alone measure any meaningful amount of light reflected off of it hitting any square inch of ground anywhere, with any instrument you can come up with. And it's covered in reflective shit already -- in fact, most manmade orbital objects are, in order to prevent the direct sunlight baking the fuck out of them in the vacuum of space where they can't rely on the atmosphere to carry the heat away.
At best, even if they manage to deploy a massive Mylar foldable mirror in orbit that's hundreds of feet across, they're only going to be able to light up a small patch of dirt like wussy old moonlight, and even then they'll only be able to do it in one place. Adding more targets will by necessity divide the light output in a linear fashion even if they somehow make it work like a huge DLP mirror array.
This simply can't work.
It's certainly a stupid idea if your trying to illuminate at the suns level, but if you wanted an area to have permanent moonlight? Not so unreasonable.
The moon is 400,000 times dimmer, so 1km^2 of mirror, which is ridiculous, could illuminate an area the size of Germany.
New York metro area is 12,000km^2, which would only need a mirror 173m on each side.
Actually might not be a bad tourist attraction for a crazy city, permanent artificial moonlight.
Unless it has AI I'm not interested
Anyone know someone that has bought into this? I've got some magic beans and a bridge to sell them,
The catch is that the reflected sunlight from a small area on the reflector will be spread over a very large area by the time is reaches earth, so the energy each panel could collect is to small to make economic sense.
This would be great for pranking people into thinking that they are getting abducted by aliens or that God is going to be talking to them.
This has some real futurama wormstrom energy to it.
Can I pay to point the sun at someone who is making my life miserable? Preventing them from getting a good night's sleep will surely make things better, right?
Oh hey... Look! It's exactly the kind of thing I trust a for-profit tech company with!
Are you as excited as I am to follow the journey of how this leads to you and I paying individual daily subscriptions for basic access to sunlight (and the quality of that sunlight being filtered into multiple premium tiers - light basic, light & heat+, light & heat & UV ultimate++)?
Its light during night time. Not daytime...

This is literally a totally spies episode
James Bond Die Another Day ahh post
Simpsons did it first .
If these idiots actually try it, we should stick their mirror where the sun don't shine.
