The one actually called the Megastructure is obviously the best (no pics cause on mobile)

...

...

there is only one

THE Megastructure is my favorite setting in anything ever.

Not exactly megastructure but I do like Toriyama's pod building design

...

The City of Illness in one of Kino's OVA.

all of GANTZ

this.

macross?

...

You're not referring to The City right?

Is this a swimming pool?

...

...

...

...

NO BOYS ALLOWED

isnt this a real thing in development?

...

this was very fascinating

No one is beyond ideas on paper in real life. We don't have material with the necessary tensile strength needed.

we actually can produce material theoretically strong enough to support a space-elevator but only on a near atomic scale

Too bad mass production scale has too much errors in the structures to let it scale to usable size right now. Hence my statement.

I know, I know. I wasn't trying to argue, just throwing around useless fact. maybe we'll see the technology in our lifetime? can't wait

Maybe we'll reprogram bacteria to make it for us.

its so easy. we take nippon robot dna and put it into common cold. reprogram to whatever but maybe we need smaller usb?

...

>what are some interesting megastructure
oh boy
>shown in anime
oh well

The domed cities in Ergo Proxy

...

research is ongoing and research-stage competitions for design components are done. but it's one of those things which has the time-frame of decades. If we're lucky we're going to see pilot projects in our lifetimes, but don't count on it.

There's a whole manga about that.

...

I like Blame, but I think Biomega is a better story.

we are never going to see a space elevator because its massively stupid and impractical compared to space planes and muskrockets

not to mention its a stationary stick that will be pelted with high velocity space trash all day

Not really a megastructure but the Comiket building is cool.

Aldnoah had some nice bases in asteroids and on the moon. Well, most space mech shows will have some megastructures here and there.

>the galactic alliance basically has shit that is comparable to The Culture technology
>singularity-powered colony ships, possibly with free-floating bits held together forcefields
>artificial wormholes

>hahaha, just kidding, we won't show you any of that
>you get to watch mesoamerican ocean hippies instead, whose pinnacle of technology is abusing an old orbital mass driver as oversized artillery
I am still mad.

>massively stupid and impractical compared to space planes and muskrockets
Maybe in the short term. The cost to launch something with a rocket or plane is astronomical compared to what you could lift with an elevator though. The problem is the initial cost being very, very steep.

It costs about $10,000 per pound to lift something into space right now (nasa.gov/centers/marshall/news/background/facts/astp.html)
Even if a space elevator costs $500 million, you'd only have to lift about 500 000 lbs for it to work out. Which if you're colonizing, mining or building anything significant is going come pretty quick. Hell you make that up in just over 600 launches of a standard crew of 5 astronauts even if they took literally nothing else with them.

...

I think he's referring to Blame!

No, in the long term spaceplanes and rockets are stupid due to their energy inefficiency. If you want to move millions or even billions of humans and the resources they need into space that would require a stupendous amount of fuel. We're talking megatons of fuel here.

what-if.xkcd.com/7/

A space elevator can lift the same amount of material into geostationary orbit while consuming far less resources.

We don't even have practical space planes yet. SSTO planes may not be all that great because they have to lift a more complex engine, have more drag due to the air intakes and don't benefit from staging like modern rockets do.

Seriously? I didn't ever look too closely into the tech of that show

>500 million
We spend 10 times that on pipelines, tanker ships, drilling rigs, refineries, etc. Try 500 billion if you want a more realistic estimate of the price of a space elevator. Probably closer to $1 trillion+

>this not a story is a better story than this story

The city in Blame
It's a Dyson sphere

are you retarded

What show is this?

...

Gargantia, I believe.
>First episode introduces this expansive sci-fi setting with interesting mechanics, politics and a fairly good villain faction
>Lol here dick around on waterworld for the rest of the series

Rewatch the first 10 minutes of episode 1. They throw around a lot of far-future scifi tech in that short time frame on both sides of the conflict.

...

...

...

>move millions

Lol no

If you're not moving at least millions then your space program is an irrelevant joke

Don't forget the general shitiness of
>the hideauze are humans from some experiment gone wrong
Absolutely atrocious twist

no

This is fucking stupid.

1. Solar panels are individual units that large? Do they replace the entire thing when a few cells go bad? This is why panels are relatively small.

2. That is not nearly enough solar panels(Regardless of the efficient) to run a single one of those buildings let alone make a dent in that entire structure.

>gone wrong
not at all. it was an ideological conflict between the bioengineers (the evolvers) that wanted to modify the human race to be space-capable on their own and the machine faction that basically wanted to build space habitats optimal for current-day humans because that's how humans should be.
I think there might be some wrinkle that they regressed mentally because they didn't need all the science stuff once they lived just fine in space. But that might have been propaganda by the galactic alliance. The squids on earth seemed relatively peaceful at least.

So while the squids were humans all along twist may have been a typical butcher twist it was actually still a poitically interesting backstory.

Exactly my thoughts. why don't they plaster the solar cells on the rest of the structure too?

The lack of individual subunits can be excused with artistic licence. It has to be recognizable for the viewer as solar installations within a short timeframe at 720p and yet look futuristic. Also remember that PV power plants were a less common sight back then.

Also highly impractical. Even if there was a hundred decks, you couldn't grown enough food for the homes and supposed people that inhabit this thing shown.

Takes roughly 2.5 acres and great knowledge to actually produce enough food for an individual, and that's just veggies and no meat diet. A couple thousand?(Even hundred homes) you won't make a fucking dent in actually feeding that population. Worse yet if people live below, and even unachiveable if all lower decks are just farms.

Isn't it called Tokyo Big Sight?

yes, but for this audience it only matters as comiket building

this megastructure exists irl

...

They hold more events than comiket!

Might be possible if lower decks are mostly high efficiency red light farms. Those things massively increase the crop yield per foot.
This guys has a nice breakdown on the math for it, though he focuses on Arcologies its a similar concept
youtu.be/TqKQ94DtS54?t=17m15s

yes

You still need a magical energy source if you want to grow staple crops (for calories) under artificial light. It's hard to beat piping sunlight directly into plants when you're still using plants.

the second most important event is wonfes and that's held in a different location

Good point. I just kind of assumed if you were moving a ship that size you had a magic energy source already

no

Boichis last Hotel probably counts.
Artificial intelligence controlled "hotel" to protect Earth species dna while the planet dies over millions of years.

yes

Nuclear.

no
dubs of truth will confirm

yes

kek

...

Academy City space elevator

...

Has that tower always been there?

>streaming

yeah it was just out of frame.

gargantia
rip best boy

You fools. without a space elevator how are we going to hold the solar ring in place?
The only reason we need.

KEK. No. There are at least 4 laws of physics that say no. And not just a "but it's haaard" no. I mean like "fuck no even billion year old civilizations get bent" levels of no.

Surprised this hasn't been posted.

I would love a game exploring this place and beating up robots with a pipe, like a jap half life

childhood is when you want to see a space elevator constructed
adulthood is when you realize that a space fountain makes more sense
by the time we have the technology to make a proper space elevator, we would have had the technology to make every other launchless system you could think of

That's a penis.

Is this from that Katsuhiro Otomo short?
