What do you call a space setting where the technology isn't the overdone sleek+symmetrical+aerodynamic but rather a bulky and realistic mess?
I could use some art of messier spacecraft full of antennae, wires, and especially ships lacking wings.
>>44471489
>symmetrical
Isn't symmetry good design for realistic space ships? So that thrust is balanced with the centre of mass and whatnot
Of course this means a lot less on immobile stations, like in your pic related
>>44471796
Most of these ships are immobile or move only short distances. The setting takes place around Earth, there is no warp/lightspeed form. Travel ships are smaller and symmetrical but I'm focused on slow-moving dwelling ships and living stations that generate their own power (sometimes their own food) and receive resources from smaller ships.

Ships like that only look that way because they're a mess of ground-launched modules developed over the course of decades.
By the time we're actually looking at casual interplanetary travel, orbital construction will be a thing, and ships will be at least Firefly level in appearance.

It's also a fictional cgi pic. The real ISS doesn't have a huge dish-style antenna on the back or a pair of cannons on the front.
If the ships are based on planet surface there probably must be some aerodynamic design.
However, one could imagine a type of bulky ship assembled in orbit and only used for interplanetary travel. And then another type of more aerodynamic vessels optimized for transporting things between the surface and the ships in orbit.

Fine, let's decide right now that we're all of us going to refer to it as Rocketfun instead of Rocketpunk.
>>44471796
I'm sure the goddamn rocket scientists, of all people, can figure out where to put the thrusters such that the vector of thrust passes through the center of mass regardless of how bizarre or asymmetric the ship is.

In the case of the term rocketpunk the "punk" is at least vaguely suitable, as many rocketpunk settings imply a proliferation of suitably low-tech space travel, rather than keeping it solely in the hands of governments or billionaire techies.
It's at least somewhat more punk-acceptable than that other name for cogfop, as far as I'm concerned.

>>44472614
>literally can't deal with words evolving
>>44472959
Yeah but there's literally no reason to design it that way. Especially since you'd need to have multiple sets of thrusters (main, RCS, and possibly hover and/or retro), and you'd want to maintain maneuverability as best as possible even with several non-functional, not to mention changes in center of mass with different loading conditions, etc.
>>44471796
>>44471895
>>44472959
>>44473017
>>44475244
Lets not be forgetting that the center of mass moves as fuel gets consumed, unless you're using a propellant-less drive (Fuck that Newton guy, right?). So even if your center of thrust is perfectly inline with your center of mass at the beginning, if your vehicle is asymmetrical they'll shift out of line with one another. Unless you have some way to move you engine back in line or move your center of mass (both a waste of energy and needlessly complex) you're going to find yourself accelerating around your center of mass every time you set thrust to greater than zero.
This means you're going to, at the least, want your fuel storage and engine clusters to be symmetrical unless you want to waste fuel and energy keeping yourself pointed straight.
And if your going to put time and effort into that, might as well make the rest of the ship symmetrical too.

>>44479104
Well, that does depend on your engines as well. It's very true for Ye Olde chemical rockets, and still pretty relevant for most nuclear-thermal rockets, but for stuff like plasma or ion drives, you're not going to be spending fuel at any rate that will make a difference in your center of mass.
>>44479084
>Yeah but there's literally no reason to design it that way.

I can think of one example right off the top of my head why you're wrong, pic related. it's got left/right symmetry, sure, but it's up/down symmetry is all sorts of fucked at every stage of it's flight.
The main engines are pointed away from the center of mass of the big external tank, while the solid boosters face straight up, so at launch, the thing is actually blasting away diagonally. And once the drop tank is released, the little orbital manuvering thrusters on the back are still pointed upward to face through the center of mass of the shuttle orbiter, honestly not sure where the monopropellant for them sits inside the thing.
The RCS thruster blocks are all sorts of an asymmetrical mess, since they can't be on the bottom or pointed directly down or re-entry would fuck them.

It doesn't follow. Most of the issues with space travel begin with the fact that we don't have the technology to magically solve ALL PROBLEMS yet. Once we've MAGICALLY SOLVED ALL PROBLEMS, we can worry about space travel.
For one thing, figuring out a way to survive in a radioactive hostile environment with shit heat dispersion and next to no food or energy sources, in a tiny area, for decades at a time.
Once you've solved that issue, you're a hell of the way there, but this sort of thing would absolutely revolutionize life on Earth as well.
I'm not anti space research, we should definitely throw money at space corporations etc., but most innovations needed for space travel would be awesome for all things.

>but for stuff like plasma or ion drives, you're not going to be spending fuel at any rate that will make a difference in your center of mass.
Thank you for making it clear you have no understanding of the subject. As long as an engine uses a propellant the center of mass is going to shift in some direction as the fuel gets consumed. With low thrust, high ISP engines like the NSTAR, you still need enough fuel to leave orbit (11 or so km/s for earth) and to to slow down relative to your target and enter orbit around it (if you can).
This means you're still bringing a fuckton of fuel. Especially if your craft is large enough to carry four to eight adult humans, supplies, and a re-entry vehicle to say, Mars.
>pic related.
There's a whole list of reasons we no longer use the shuttle, big one being it was expensive as fuck to maintain and use. You'll notice how the main shuttle engine is angled. Guess what this does? It wastes fuel.
You'll also notice how the Shuttle never left Low Earth Orbit. It wasn't designed to. It couldn't even survive a round trip to the moon and back.
Now if you want to talk about a spacecraft that looked asymmetrical (and was slightly) we can talk about the wonder that was the Lunar Module.

When the book was written it was thought that storms like the one that forces the evac were possible/common on Mars.
Between the book being written and the adaption being made more data from our rovers and shit has shown that actually Mars doesn't have storms like that.
At least, that's what I assume he was talking about, and part of why he specifically called out the movie, since, yes the book was also incorrect about that, but it was accurate given what we knew/the common theories were at the time, while the movie just went "fuck it, we'll stick with what the book says, even though now we know that to be incorrect"

Completely agreed. The energy requirements to maneuver within our solar system in a timely manner are absurd. That's why this thread is about a realm of science -fiction- not science.

>>44480150
How do those work, anyway? Mars' atmosphere is like 1% as thick as earth's. There's not much air to make wind with, i'd think.
>>44480406
Yeah, no. Doesn't work like that.
>>44480421
That, and they don't actually hold all that much energy too.
>>44480467
i figured that was implied, heavy for the amount of power they held. If they were heavy but held a shitload of power it wouldn't be a problem.
>>44480421
Fair point. I guess you would need to massively scale down the storage of said power if simply scaling down the entire process couldn't be done.
Small-scale fusion when?
>>44480489
Scaling down the storage is generally going to be less efficient because proportionally more space will be taken up by the not-power-containing-bits.
If you've got fuckhuge amounts of power to toss around you're probably best off using it to synthesize fuel rather than tossing it directly at liftoff.

There are 100mph storms on mars but due to the thin atmosphere it'd barely be feel like a light breeze. The thing about them is that they can be FUCKHUEG and pick up a lot of very fine dust which can cause mechanical failures and such.
>>44481186
It isn't certain what the particular properties of Martian regolith are. But if it's anything like that of the moon it's probably very abrasive and much more chemically reactive than normal dust. So repeated exposure to Martian dust storms will probably seriously affect equipment.

And likely chew a hole in your hulls as well. Best to bury your major infrastructure underground, and have anything above ground protected by easily replaced plating.

>>44481186
So is it less "Darude:Sandstorm" and more "everything gets covered in shitty dust"?
>>44481278
I'd imagine it's more like earth dust than moon dust because there's an atmosphere that blows it around occasionally.
Lunar regolith is literally igneous rocks pulverized into powder by the impact of meteors. It's all tiny jagged shards. I'd expect mars dust to have the edges rounded off.

Is this an ironic parody of pretentious Internet douchebags, or the real thing taken to a comical extreme? It's hard to tell sometimes.
>>44481349
Thing you need to remember with lower gravity and a thinner atmosphere is that while, yes, the wind applies less force to the surface, a thinner atmosphere and weaker gravity means less energy is required for particles to pick up speed and their terminal velocity is also going to be much higher.
Higher relative velocity, the stronger the impact.

>Of course this means a lot less on immobile stations, like in your pic related
It's mass that's important.
Doesn't matter if the craft is symmetrical in shape. If the left side is living quarters and the right side is fuel storage, then it's still not evenly distributing mass.
So you can have asymmetrical designs- so long as the mass of the various structures is comparable in relation to the your source of thrust.
That's why it's okay to have something that looks like it sticks way out of the side of the craft- so long as its relatively lower in mass compared to stuff on the rest of the craft.

>>44480848
Avatar's design work was on point, and this spaceship exemplifies that.
>>44482605
Symmetry is a must in a lot of designs as it's the simplest way to balance a space ship around the thrust without resorting to ballast tanks that take up mass more useful payloads could be using.
One thing that I haven't seen dealt with in hard science fiction is how having a massive chunk of armor on one side of the ship being blown up would imbalance and cause the entire space battleship to list whenever it powers its main thrusters, which would be a big problem with battle damage.
>>44482518
There's an interesting mod called the Kerbal Inventory System that allows you to take up parts in special containers and assemble them on the exterior of a ship while in EVA, and one thing I've found in early experiments in in-orbital spacecraft assembly is that you need to build a fucking cage or hollow container to contain whatever you're building because the simple act of placing an object onto another one will cause the object to fly off unless you can pin it against something in a process I want to dub "inter-orbital Kabedon Assembly".

Proper distribution of mass is a must. Aesthetic symmetry is not.
Symmetry will result in a greater need for ballast tanks, since you must compencate for masses to be placed where they will conform to a symmetrical shape as opposed to being placed where they are most balanced mass-wise.

That anon is probably an idiot who thinks LH2 is helium, however don't rockets use liquid helium to maintain pressure in the fuel tanks as fuel is expended? And btw it is possible to make helium from hydrogen using nuclear fusion, no idea of how economical it would be though.
>>44483663
For your first question: I honestly don't know, I'm not familiar with such a method.
For your second: yes it is possible to fuse hydrogen into helium. That's why helium even exists in the abundance that it does.
As far as economical: no, not yet. Maybe in forty-fifty years, but not yet.
>>44471489
Used future.
>>44483663
No because Liquid Helium is crazy hard to make, they do however use liquid nitrogen though to stop the hydrogen tanks from imploding as they are emptied of hydrogen.

It won't get economical on its own in a hurry.
But you might be able to squeeze out some extra cash form selling the helium from a commercial fusion reactor. A significant amount of the helium sold today was created as a by product of commercial fission power (I'm guessing beta radiation that slowed down and yoinked some electrons, but fuck knows).

Helium comes from natural gas and other petrochemicals. As such, it is a fundamentally limited supply.
If you accept physics, that is.
>>44487597
....Ah, no. Most all our helium comes from some sort of radioactive decay, usually from uranium or thorium mineral beds.
>>44484524
They use liquid helium for that, last I checked.
>>44480482
It's not even that it needs a lot of energy-that's cheap-it's how to convert it into motion. You could be carrying all the energy in the universe in the tiniest, lightest possible battery, it won't do you jack squat unless you figure that out.

Interestingly, we're both wrong in right ways-helium tends to collect in natural gas deposits for reasons given in the article, and is extracted by fractional distillation from natural gas, but more is produced year-round by radioactive decay instead of being an entirely nonrenewable resource.

its nothing to do with the actors or the storyline, only the technology.
Also did you watch jupiter ascending? or just write it off based on the cast and promotional poster? Its very well made and some great sci fi ideas. Also some very cool races.
With Sci fi films you can't be picky about actors, you just have to enjoy the setting and technology.
Also anyone see 2010 (1984, sequel to 2001)?
It has some great scenes, particularly the one where they slingshot around jupiter. A fairly hard sci fi setting.
Outland (1981) was also very cool.
>>44492439
>Also did you watch jupiter ascending? or just write it off based on the cast and promotional poster? Its very well made and some great sci fi ideas. Also some very cool races.
I wrote it off because it was a terrible movie. Since you're sticking to vague statements i will too. 2010 was decent though. Gotta love the Ballute scene. Have you seen Darkstar? You might like it.
>With Sci fi films you can't be picky about actors, you just have to enjoy the setting and technology.
I can't agree with that.
The closest we've gotten to a decent science fiction movie this decade are Dredd and Moon. Dredd is obviously silly, but Moon takes itself seriously despite the plot of moon mining being about as ridiculous as they come. Look up how much lunar regolith has to be mined per ton of He3 if you want to know what i mean. Net Loss doesn't even begin to cover it.

Be a man. With your logic, the only non-renewable resource in the universe is energy itself.

Second question: Let's say you're right and humanity is doomed. We'll run out of oil, earth will become an over-populated, over-polluted, sack of shit and we will never be able to feasibly leave it and colonize the galaxy.
Then what? Now that we've established that you're right: humanity is fucked and the stars are beyond our reach, what do we do?

With it's current fuel loadout it's got 70,340 m/s dV with a TWR of 1.01, about 480.5 kN. With fuel it's about 66 tons.

What we do in a scenario like that is we revert to a level of population and technology that we can sustain, obviously.
>>44500890
you and yours first then.
Now, a serious answer please.

I am serious. We as a species do that, whether we want to or not. That's the definition of "unsustainable", after all. "Cannot be sustained".

>>44496992
They're from the Near Future series of mods, if I remember right.
Simply called the "Magnetic Nozzle" (the four outer engines, and the "Plasma Thruster" (the one in the middle).
Both in the realm of science fiction. The Plasma Thruster can run off of electricity and virtual particles, so it's a "EMDrive-that-works" and VASIMR hybrid of sorts.
>>44500890
Population I can sort of agree with, though good luck implementing that in an ethical way, however any step back in terms of technology would be pointless and foolish to do.
I guess you could mean that we will simply revert back to a sustainable level because of free market forces, war, famine, and other natural balances.

AI, Fusion, Godhood, Space Elevators, actually.
Space Elevators are an impossibility, even with carbon nanotubes. By the time we make something stronger, they'll be pointless.
Plus were fairly close to AI, as computer capability doubles every two years, provided we don't hit a development wall.
Cold Fusion is theoretically possible, but we dint know how to do it safely yet though.
Godhood is relative, especially if we genetically engineer a sentient species and lord our power over them like Hellenistic dicks.

Facts matter.
Will we make hard choices about the economy or about our lifestyles when we are led to believe that nothing is wrong and technology will save us from every single consequence of our actions?
Fuck no. It'll just make things worse. We're playing chicken with our future.
>>44501462
Fusion is possible though. Currently it's not reliable enough to consider, but give it a few decades and it might be feasible. We've made more progress in the past 100 years than in the rest of the 1000.
We can do flying cars, but we don't because it's dangerous, not cost effective, and plain stupid. Will the future be as imagined? No, of course not. But to deny evidence that at current rate of scientific progression, even with financial and cultural stagnation, were set for at least a somewhat bright future, provided we don't nuke ourselves.
>>44501480
That's great and all but I was asking what do you propose we do.
>>44501517
>Fusion is possible though. Currently it's not reliable enough to consider, but give it a few decades and it might be feasible. We've made more progress in the past 100 years than in the rest of the 1000.
So? It has an EROEI of 100:1 as opposed to oil at the turn of the century which was 1:100. We can't make a world on that.
>But to deny evidence that at current rate of scientific progression, even with financial and cultural stagnation, were set for at least a somewhat bright future, provided we don't nuke ourselves.
I don't think we agree on the terms of "scientific progression". We owe the existence of the modern world to discoveries made over a century ago. Oil is not something we can economically replace at our current demand. Only if we reduce energy use in all first world nations by approximately 90% will we have a technological future, and we have to start 30 years ago. Since we can't do that, we have to start today. This hour, this minute. Nobody is willing to sacrifice for the future, because they've been told that the god of technology has endless bounty, endless energy. The singularity may be the most deleterious idea to ever occur to us.
If technology is exponential, why doesn't 50 years ago look as transformative as 100 years ago? Why, if i were to go back in time, would people from 50 years ago not see anything i brought back as magical?
Look up the difference between an exponential function and a sigmoid one. Notice where we might be mistaken?
>>44501672
Reduce all energy use by countries like america by 90% starting right this second, so that we actually can be sustainable on renewable resources alone.
We can't make up the 18 or so terawatt difference between non-renewable energy and renewable energy on any global GDP. We have to reduce our use to the point where we feasibly can.
Nobody will do that. So i'm quite literally afraid that's that.
>>44501719
Except the average person has never heard of the singularity and is not under the impression that 'technology' will magically fix the future.
>>44501840
Nor is the average person under the impression that the future is something that needs to be fixed.
>>44501905
Which is why nobody is reducing their energy and resource use.
Shit, people don't even care that the low costs at the supermarket are only attained by fucking over the employees and safety and quality standards.

>>44501719
>Why, if i were to go back in time, would people from 50 years ago not see anything i brought back as magical?
You must be very young if you believe that to be the case.
Something as simple as an iPhone would amaze many of the most prominent computer scientists of the 1970s.
And that's just in a single field.
We know things today that would astound the worlds leading experts in physics, astronomy, biology, chemistry, robotics, and heck, even mathematics has made respectable promise.
We've landed a probe on a comet, we've built histories largest space station with the help of the ESA, JAXA, and ROSCOSMOS, we have high resolution pictures of Pluto, some firefighters in the Middle East are getting jetpacks, not too long ago the first stage of a rocket landed itself, the world united to complete the Human Genome Project, we have cars that can drive themselves, and I can have a video chat in near real time with the woman I love with a device that weighs less than a kilogram.
Welcome to the future that was dreamed of 100 years ago, that wasn't possible 50 years ago, and 50 years from now will be just another blip in history.
>>44501744
So everyone walks everywhere, no one buys meat products at all, we reduce global shipping lanes to 1% of what they are now, stop mass producing medical products, shrink all agricultural pursuits by 60%, impose severe restrictions on who may have more than one child, force the remaining population to either have only one or no children, and find some way to force the 3rd world nations to stop industrializing.
Not happening.
But that's far from the end of the world.
But if you honestly believe that's what we're heading to, what are you doing about it? Other than cutting back your carbon footprint, and telling people to do the same.

He's probably saying that because it's a silly shot in the dark that gives off the impression that you need to resort to name calling.
As to the actual argument, I think you're pretty obviously right in that we can do all kinds of amazing shit that people a few decades ago didn't even think about. But the specific question here is whether it's the kind of shit you can power a civilization with once fossil fuels go bye-bye, isn't it?

>nobody is reducing their energy and resource use
So are you just ignoring the fact that many people are as efficient as practical with their energy use? Or that basically every piece of technology we use has been getting more energy efficient for decades?
>>44502245
I won't discount the inventions he lists, just that the discoveries that made those inventions possible we made a century ago. We haven't discovered a new source of energy since photovoltaics.
All of the growth has been in old branches. There have been startlingly few new branches. Quantum mechanics is probably the most recent thing that we've gotten use out of, and its widest application is the CMOS chip that keeps your BIOS settings when you turn off your PC.
>>44502286
>So are you just ignoring the fact that many people are as efficient as practical with their energy use?
The people in the third world, yes. The red in this image is absolutely unsustainable.
>Or that basically every piece of technology we use has been getting more energy efficient for decades?
Unless you're saying that we can make 110% efficient machines, then that's really just an argument in my favor, isn't it? If a technology has 40% energy efficiency, then at most we can double it before hitting the thermodynamic wall.
>>44502291
The widest application of quantum mechanics is the condensed matter physics that made people understand semiconductors without which your computer would still be running on fucking vacuum tubes.
>>44502356
And transistors, yes. That's why we've seen such a reduction in size of certain electronics, and it gives people the sense that this should apply across the board.
But why would it?

And no star wars prequels or special editions.
>>44502172

>>44502241
Well considering we already have silly flying bikes, we've had airships and submarines for a while, we also have remote controlled weapons, and communications systems that operate at near light speed, I'd say Verne was spot on.
Sure we're not colonizing other planets yet, but we also aren't making potions to make super soldiers, or building metal woman to take over society. It's almost like science fiction is a poor way to measure progress.
>>44502391
And thanks to those advances in electronics we can now perform surgery remotely, through a fiber optic cable, through the patients blood vessels. I have a 3D printer than can make parts to allow my to fix say, my office chair, on demand. I don't have to spend gas in my hybrid car (also possible thanks to advances in the fields of computer science, electrical engineering, and others) to go buy the replacement part for said chair. I built a small wind turbine in my back yard and got a loan to install solar panels on my roof. My office chair has a foot pedal system that I use to recharge the battery packs for my power tools while I'm listening to someone give a lecture from halfway across the world. We have built prosthetic limbs that can convey the sensation of touch to their user, and can be controlled via our thoughts. We have given individuals once confined to a wheelchair the ability to walk. We have and continue to cure diseases that ravage the world. Genetic engineering alone has saved countless lives.
