California-based startup Reflect Orbital aims to build a swarm of 4,000 giant mirrors in low Earth orbit to "sell sunlight" to customers at night. Experts warn that the mirrors could mess with telescopes, blind stargazers and impact the environment.

Reflect Orbital, which was founded in 2021, has recently taken the first step in a scheme to sell sunlight at night by bouncing solar rays off giant "reflectors" that can redirect the vital resource almost anywhere on our planet. By doing this, the company aims to extend daylight hours in specific locations, thus allowing paying customers to generate solar power, grow crops and replace urban lighting.

But experts say it is a wildly impractical plan that should never get off the ground. What's more, the resulting light pollution could devastate ground-based astronomy, distract aircraft pilots and even blind stargazers.

New startup idea: iAir. Pay a certain amount of subscription for air, or we will choke you to death!

Mel Brooks had this covered in Spaceballs.

All of these wacky silicon valley startups poping up just shriek very loudly that there is too much capital and not enough real economy to invest all that money into.

This is the material analysis we need to be doing. During COVID I saw farmers shredding crops instead of selling them because we lacked the transportation capacity to get food to market. "How the fuck is that even possible?" you ask? We rely too much on individual truckers when we should be using rail... And that's kind of an analogy for the whole market.

No system in place to ensure there is enough energy, water, food, steel, concrete, lumber, etc. to go around, just this vague hope that "the market will respond to price information as it always does".

Well now that price information is telling people to invest in space mirrors to send sunlight to their AI-powered saffron gardens, employing cheap foreign workers rather than local labour so that they can sell the spice to wealthy people. So yeah I think that mechanic is busted now and needs a rethink.

Because they've destroyed the economy

Does anyone else remember the scene in the movie called "The Core" where a giant beam of light started frying people and melting bridges?

I just imagine the first places that put in in-door lightnig like "here now you can work later in the day" now they will be like "Oh look you can work 24/7 now it's never dark anymore".

this startup's CEO and finding members should be trialed for crimes against humanity

Don’t worry they’ll get bought up by starlink or Palintir.

[–] pjwestin@lemmy.world 8 points 2 days ago

Scientists: One desperate plan we are considering to combat climate change is a series of gigantic mirrors to deflect sunlight away from the planet.

These assholes: OK, but what if, like, the opposite of that?

Why are all the experts going on about the fact you might blind pilots but not talking about the fact that it won't actually do anything.

It would have to be an astonishingly vast megastructure for it to have any effect at all. If we were talking about a structure 100 km across or more they might actually have some sort of point.

"We also plan on patenting atmospheric air and granting reasonably priced usage licenses for limited daily volumes to every man, woman and child on the planet. It'll be great!"

I almost wish this was not a practical impossibility just so we could get to see the headlines when some misalignment fries an island of billionaires like bacon.

they'll start by selling sunlight at night, but we know that it'll end up being that we have to either pay to have sunlight in the daytime OR pay to not have sunlight at night.

Oh, I think it's a wonderful plan for the startup. They don't own space, they don't have any control over space, they're selling something that they know they can't possibly deliver because they would have to get people to agree that they're allowed to steal sunlight and space, and that would never happen. It's great for them. They can get some cash.

Its also just fucking stupid.

You have two options:

One build an insanely, comically expensive series of mirrors to move solar energy to solar panels so you can power them at night...

OR...

Install twice as many solar panels on the ground. OR the same amount and battery storage, or any combination thereof.

I think there’s a couple of Bond villains with similar setups. Not sure how I feel about that, but felt it was worth mentioning.

I won’t lie, the idea of sunlight on demand sounds interesting… but then capitalism ruins it before the environmentalists even had a chance. (not trying to downplay environmental science here, just being cheeky)

Throw these guys in a volcano. Add the billionaires and tech capitalists while at it.
