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.

Thought I was in the boring dystopia community instead. I suppose I'll just continue to hope that this is too impractical to happen or that those responsible aren't competent enough to make it happen.

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".

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.

Cut to: man watching in shock as his "mirror satellite" burns people like ants under a magnifier

Very useful on the off chance that vampires are real. Otherwise.... Less so.

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?

🎵 Take my love, take my land, take me where I cannot stand. I don’t care, I’m still free, you can’t take the sky from me.

Wait, no, don’t take the sky from me!

Just like a certain great philosopher said, "The sun is a deadly laser"

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.

It works with water, why not sun? People don't have to agree, no one's going to ask them. It'll just happen.

Life on earth depends on day and night cycles. This would cause an environmental disaster. So many animals would get fucked up.

What are the space laws for if we nudge it into the sun?

for solar, a 5km diameter solar farm might hold 10m square meters of panels. at 250w each, 2.5gw solar farm. 4 times a full moon, is 1/100000th the rated capacity (noon at equator) of panels, and so 25kw of power. At 10c/kwh electricity revenue potential, such a farm (exists only in China) could break even offering to rent night light at $2.50/hour.

Batteries charged by solar can deliver profitable electricity at night for far less than 10c/kwh.

If you just want more light somewhere, it would be far cheaper to do from ground systems.

Have we seen this episode on futurama?

Why put mirrors in space when you can SELL SHARES in building mirrors in space to redirect sunlight.

Worth trillions, don't you think? Not the end product - just the design and endless alpha model.

Shit... you think the F-35 was a complete boondoggle(*1), you ain't seen shit. Space is BIG. Price tags $,,$,,$,,$,,$


(*1) and it remains so to this very day

Maggie Simpson will sort them out.
