Laugh all you want. But this will be the only thing that saves us during the 2066 vampire wars.
Idiot! Just don’t invite them in.
I want to sun my asshole during night hours.
You’re doing it wrong silly, you charge your butthole with moonlight.
This is horrifying idea
Just looking at this has me feeling really concerned when it comes to the environment and nocturnal species.
Well unless the mirror is 20km across, they won’t notice because the whole idea is insane.
This is like the Romans thinking they are going to build aircraft, we are no way we are near the level of technology required to do this. This is like stage 2 civilization level stuff.
Oh okay, it’s just that I feel attached to the woodlands and find comfort being in the middle of the forest, and seeing what is going on here made me feel really concerned for the environment and nocturnal species. Like, what if you happen to be an animal that is on the prowl or is active at night and all of a sudden its daylight due to sunlight being reflected from a mirror in space?
How would it work if it’s not that large, though? They could only sell sunlight to people who are within the target radius, but that would be very temporary
Very temporary. If it’s going to be very has to be close to the Earth or no one will see it. But if it’s close to the Earth it moves so fast there’s no point, orbital speed for that altitude is something like 7.8 km per second.
The only way to make this work is to have a truly vast mirror and have it out at geostationary orbit, then angle the mirror as needed to turn on or off the sun but then you’re going to be covering a significant area of the planet.
To demonstrate how utterly insane this idea is, this is the sort of thing a civilization would do if it decided it wanted to terraform Mars. Doing this wouldn’t be the efforts of a single corporation it would have to be a global effort, we don’t currently have the capability of putting something that massive in orbit, we don’t have a way to reliably control the mirror, we can’t even manufacture a mirrored surface that large, and there have been zero studies on the environmental effects of doing this. It would honestly probably be easier to build a space elevator.
Oh and even if we did do all of this, despite it being impossible, it would only work for a couple of years and then the mirror would get pushed out of orbit by light pressure. The only way to counter that is extremely complicated mirror geometries, and even more mirrors, making the total surface area in the hundreds or even thousands of kilometer range.
It does sound ludicrous…might be better off making a concave mirror so it reflects and intensifies the light…like a giant magnifying glass over an ant hill. Yeah…that’s how they should do it. Nothing gonna wrong with that.
A concave mirror would focus all of the light from a wide area into a single point. What you’ve created there is a giant space laser. One that only works at night because you need the sun on the opposite side of the Earth to reflect it.
Also all of the previous problems about it needing to be massive, or close to the Earth and moving faster apply.
Yeah, what you just stated about a concave mirror is not only ludicrous, but would be very destructive to the wilderness and wildlife and probably would be time to contact every wilderness and wildlife defense group to have this so called start-up shut down.
My startup is going to rent sunlight interceptors that block the extra sunlight sattelite beams that your neighbour rented and what is keeping you awake all night.
🤣🤣 literally the only reaction to this!!
Luckily it’s just an attempt to scam some dumb VCs
Startup says it wants some more cocaine and wants to know if you know anyone with some more cocaine because some more cocaine would be fuckin’ great right now holy shit
I could do a bump, ya know, if you got a little extra.
This gives me a great idea for a new startup! I’m going to put a giant mirror in space, and you’ll need to pay me to turn OFF the sunlight at night.
The people behind that startup are in tears strangling each other wishing they thought of this.
Did this dude get VC $ by presenting The Simpsons “Who Shot Mr. Burns?” wtfff is this nonsense 🙄
WERNSTROM!!!
Like stealing candy from a baby…
Modern day startups: lays out a dumb idea.
Valuation: $3B
Startups: The most dystopian shit imaginable
VCs: “You son of a bitch, I’m in!”
Please, no.
It’s a grift. They came to steal VC money.
I’d like to have darkness during daytime. I’m not sure I would pay for it, but I’d like it very much.

You fucking watch yourself, alright? You’re on thin ice.
That was 47 years ago.
Your math is off. It’s closer to 67 years ago. You forgot to carry the 2
Nobody will invest in this until they throw some “AI” in there.
It’s so dumb uggh. Getting the same power output as the sun would need a MINIMUM surface area of the size of the area on earth it would illuminate.
So say the use case is extending daylight time in Anchorage, Alaska during winter. You would need a mirror that has MINIMUM surface area that of Anchorage. Somehow, it would need to be in an orbit that can reliably reflect light to Anchorage at all points.
Then, it would most likely be in low Earth orbit as putting it higher would require bigger mirrors. However, if u are in LEO, u are also moving incredibly fast. You would thus need an array of these super large mirrors.
All of this for what? Something that an led can do incredibly easily?
Would it not be possible to deflect it through a lens? Couldn’t that increase the spread area significantly and because of the contrast at night you would only need a fraction of the light intensity to make an area feel well lit?
You don’t need a lens, just a differently shaped mirror. Their point is just that the light you capture is based on the mirror’s surface area, so if you are selling sunlight-equivalent amounts of light you would need a mirror of equal area to that you are selling. You would not need such a large mirror to sell an area of dimmer light, and you would not need a lens.
- A convex mirror could work, sure. A lens would be impossible to construct for the size necessary.
- I don’t get what u mean by “contrast at night”, but sure - let’s assume that you would need 5% of the power at noon. You would still need a mirror with a surface area of 5% of the area you are illuminating.
