- dietr1ch 3mo agoTo anyone thinking that 18m² isn't that big for how large the space is, please recall how bright reflective things shine during the day when you hit the right angle.
- whh 3mo agoEvery colleagues watch face.
- csallen 3mo agoA gigantic source of light in the sky that lights up a part of the Earth and is too bright to look at is... the sun. I think we're all used to the sun.
- pastel8739 3mo agoI personally am _not_ used to seeing the sun after sunset and before sunrise.
- dnel 3mo agoNeither is nature, this sounds like an environmental disaster waiting to happen
- jack_pp 3mo agoconsidering plants grow just fine with grow lights, they don't really care. same with co2, they LOVE CO2
- iamacyborg 3mo agoNature is more than just plants.
- jurgenburgen 3mo ago> they LOVE CO2 Plants can absorb some more CO2 and it improves their growth slightly but saying they LOVE CO2 is an exaggeration.
- KeplerBoy 3mo agoThey turn it into sugar, what's not to love?
- csallen 3mo agoSolar panels aren't nature. Shining lights on solar panels is not going to be an environmental disaster.
- _vertigo 3mo agoeveryone’s seen ads before, mind if I put a giant ad in the sky for everyone to look at?
- digitaltrees 3mo agoIf one person owned the sun and could charge all humanity for access to its light then maybe that would be a relevant example
- csallen 3mo agoWhat do you think is being proposed, exactly? Some sort of alternative sun that's going to shine on the entire earth, that we'll all be forced to look at?
- digitaltrees 3mo agoNo. I used a rhetorical device to highlight a theoretical monopoly we assume would never exist. But imagine I launch a space sail that can cast a shadow on any part of earth I chose. I could block or unblock sunlight at will and grant access only for paying customers. Is that something that should be permitted?
- zefr0g 3mo ago18x18 is 324m^2
- blooalien 3mo agoTo give an easy visualization for most people (average Americans, really, because most other people in the world already know what a meter looks like), imagine that the average doorknob is about 1m above the floor, so imagine basically the bottom part of a typical interior door is about 1m sq. Now, make a square out of 18 of those pieces wide by 18 pieces high.
- mzronek 3mo agoAmericans will measure with anything but the metric system.
- blooalien 3mo agoExcept for those few of us who grew up interested in science, because science pretty much world-wide (even in the USA) uses metric for pretty near everything. I've used metric for my entire life, and been ridiculed for it that entire time by all the same morons that think any interest in science makes you a "nerd" even if you also happen to play and enjoy sports (despite almost the entire rest of the world standardizing on metric long ago), and despite the fact that most folks in the USA are already using metric themselves every single day. Yet somehow metric is "too hard to learn, waaah!" (It's based on tens, just like our money. Too complicated? Gimme a break!) Hell, our sugary fizzy drinks even all come in 1 and 2 liter bottles, FFS!
- amelius 3mo agoAnd if they do, they will call it things like "square doorknob".
- NikolaNovak 3mo agoI feel "about a 8 floor building" would be a good ROM :)
- 3mo ago
- potamic 3mo agoWut? This has to be some sort of a scam. There's no way you're going to be reflecting enough light from hundreds of kilometers away.
- shafyy 3mo agoI really hope it's a scam, because if not, and this is allowed to exist, we're fucked.
- kulahan 3mo agooh dear, the stakes are so high
- selivanovp 3mo agoIt's not. USSR and Russia experimented with space mirrors and was able to light significant territory. It was a successful program, but in 1993 Russia had no money to continue the project, so it was wrapped up.
- Coffeewine 3mo ago[dead]
- nerdsniper 3mo agoIt works fantastically well for construction and military applications.
- verzali 3mo agoBased on what? You get the light of the moon for about 5 minutes.
- nerdsniper 3mo agoI’m pretty sure the plan is to have tens of thousands of them so that they can hand off from one satellite to the next. I know this tech would have been fantastic when I used to work on oil rigs in super remote locations.
- blackhaz 3mo agoI think this needs to be addressed with a crowd-funded projectile. This sort of stuff must be done on a planetary-scale consensus basis only.
- tticvs 3mo ago[flagged]
- theoreticalmal 3mo agoWhat a terrible tyranny of the majority problem that would be. I reject this idea completely
