It is possible to build an O’Neil habitat that allows comfy living space for 100,000 humans using only traditional agriculture (that’s 3 acres of “land” per person) and only existing technology.
Note: whenever we have these “life in space” threads someone always posts “Why not genetically engineer ourselves for zero gee and synthetic diets and just turn into creepy pathetic space ants?”
Answer: You make a disturbingly good point. Go ahead. I would like my descendants to have to option to stand on a planet’s surface. Call me sentimental.
So, assuming we are all not eager to stop being human as we know it…
Dismantling the planet Mercury gives us enough metal to build 9 billion of the habitats described above. Of course there are many smaller bodies we can harvest first, much easier to mine.
The Oort cloud has an assumed mass of 3×1025 kg; lots of water, nitrogen and some carbon (in the form of methane)

Basically, it seems we can comfortably support a total human population of 1x 10^14 with just the resources available in this system. All at levels comparable to middle class 1st world citizens today. And that’s WITHOUT any major technological advances; just fancy engineering based on current science. Admittedly, a fusion reactor is a LOT of fancy engineering but we know it’s possible. I’m looking at a great big one outside my window now.
I wanna warp drive too but a population of 1,000,000,000,000,000 taxpayers and consumers is going to make that a lot easier to pay for.
Thomas Jefferson speculated it would take the American people 1.000 years to populate the West coast of N. America but 200 years later L.A. was bigger than NY. Once we get started this will happen amazingly fast.
Please don’t nitpick this thread with little engineering problems that we have centuries to work out; offering solutions to those problems is quite welcome.
Don’t just post “Not possible” without explanation. That just tells us you don’t have the imagination for this conversation.

Suppose we can pay to create a small, self sufficient space colony. Just 200 poor bastards stuck out in the asteroid belt. They have 2-3 small habitats, a hydroponic garden, chickens, some solar panels and a dozen little putt-putts to go from rock to rock. They have what they need to survive indefinitely but if they want to grow they gotta dig for it. Need more electricity? Mine and build more solar panels.
If we just got that far I think the same maniacal pioneering spirit that allowed such rapid expansion across Australia or the Americas would take over.

If we spread the habitats out along the path to another star (this assumes fusion or some other big energy source) then interstellar travel would be as safe and comfortable as a US highway; you can pull over and get gas/food/lodging at any off ramp. We just have to keep shipping hydrogen or other fuel toward the middle of the route.

In my opinion, the first step we should make is to increase our presence in Earth's orbit, namely making a space-shipyard. Minerals mined from asteroids and comets could be stored in big silos in orbit and used for the manufacture of stuff in space.

With this you won't have to fly everything to space, only ferry people and special equipment up and down (this is where a reusable spaceplane comes in).

That coupled with a mining colony on the moon will give us a solid footing to expand and build the stuff your post is about.

>>They have what they need to survive indefinitely
To stay alive indefinitely they need enough of an industrial base to maintain a habitat.

This means enough of an industrial base to make everything in the habitat, including itself. One would have to make things like precision machinery, microchips, motors, etc to keep the colony running.

One would probably need more than '200 poor bastards' for this industrial base.

However one would need 0 'poor bastards' if we made an automated industrial base that was capable of self-replicating itself, IE, self replicating mining robots.

Now estimates of development complexity for a self-replicating robot place it in about the range of a modern microprocessor(pentium 5)

In addition, seed mass is estimated to be around 6-100 tons. And since the systems estimated are primarily designed to work on the Moon, it'd probably cost about as much as 0.5-7 Apollo launches to send the seed to the moon.


At the very most the whole system would cost a couple billion dollars to send up and develop, this is three order of magnitude less than sending up 200 poor bastards.

Automation and machinery could make food production for an entire colony be run by one family. They don't even have to worry about rain, weather or whatever because everything will be artificial. A machine will plant, no one have to take care of it and some time latter a machine harvest it. Pest control wouldn't be a problem since you can exterminate all pests in the colony once and thrive on the enviroment free of pests.

For repairing the colony i think humans and machines working together would be more reliable but still won't need much people for that either.

I think you could make something like 10 colonies with 100 people in each. People could go from one colony to the other with certain regularity (maybe once a day the colonies would allow traffic between colonies) this way each individual colony don't need to have schools for every field but instead people would move to different colonies to study for different jobs.

Earth will have the same technology and more so, and the Earth does not have the parasitic drain of maintaining a working gravity rich biosphere, ie, the standard of living on Earth is superior. Not that I'm saying we're headed toward an arcology rich future on Earth. The same problems apply to Mars.

One thing I have learned in my 55 years in the real world is to always have extra, a plan "B", more than you need. Scraping by means you have already made some bad decisions and it leaves you vulnerable to bad luck.

Planning and hard work transfer into "gets" and insuring you have lots of room and resources will make the individuals and the colony as a whole stronger.
Of course it will be hard; 16 or more hour workdays from the cradle to the grave. Colonists have decided to trade comfort for a more meaningful life. But that choice deserves a big soft bed and an inefficient, wasteful little flower garden.

Initially, yes, it will be very bad. Colonists won't be able to have hamburgers or pork and will have to live off of a hippy diet of freshly grown fruits and vegetables, granola, algae, fish, goat's milk, chicken eggs because pigs and cattle require too much land and resources.

Colonists will also have to recycle all their clothes and cloth like fucking hippies or wear clothes made out of beta-cloth(cloth made from glass) because growing cotton to continuously turn into clothes will eventually fuck over the colonies biosphere.

Because it's expensive to send stuff up from Earth colonies won't be able to drink Budweiser and will have to brew all their own craft beers like hippies!

Same thing with razor blades, it will be expensive to send them up, so people will grow their beards out and have hairy legs like hippies!

But worst of all, movies will probably be released later than on earth, magazines will have to be faxed up black and white(porn will suck!), colonists will have to listen to the same music over and over, because it's expensive to send up records, and ....

Wait, WHAT DO YOU MEAN IT'S NOT THE 1970s? Everyone has a computer now? They can use this computer to 'download' books, movies, magazines, and music?

You've confused the fact that because you reached for something commonly attainable, and good, I am not disputing that, that that means that anything is within reach. Or: finding a wife on earth is easy and common, no human being has traversed the boundary to live in space like you imagine.

You've also confused margin as being specially applicable to unattainable wanton excess. The meager existence can have margin built in too. The meager existence can afford more margin. The meager existence can support more people for given capital. More people = larger economy. Larger economy = more resilient and larger output. Larger economy, perhaps larger than minimal viable economy.

>> No.6131552

Just a thought, but wouldn't a built-up colony be more expensive than an open-air one? If you're filling all that interior empty space with buildings, you're going to have to ship up a lot more mass.

The "Skyscrapers" approach works on Earth because we charge for land by the square meter, so building up makes sense - it results in more people living on the same square foot of expensive land.

In a space colony - because the restrictive cost is materials and pressurized volume - living space would be charged by the cubic meter. So building up your colony's interior gives it the ability to support more people, but the reduction in cost-per-person may be relatively slight; depending on how much value people put on empty space it may actually be worth it to just build another colony.

Also, note that for O'Neill cylinders you basically can't build up to skyscraper heights - the gravity as you approach the center quickly gets too low to be long-term habitable, and the tidal forces get uncomfortable.

I'm pretty sure insects will be part of the daily diet in space colonies.

The Black soldier fly larvae are edible to humans. The larvae are highly efficient in converting proteins, containing up to 42% of protein, and a lot of calcium and aminoacids. In 432 hours, 1 gram of black soldier fly eggs turns into 2.4 kilograms of protein.

When the larvae are done growing, they enter a stage called "prepupae" wherein they cease to eat, they empty their gut, their mouth parts change to an appendage that aids climbing, and they seek a dry, sheltered area to pupate.[6] This prepupae migration instinct is utilized by grub composting bins to self-harvest the mature larvae. These containers have ramps or holes on the sides to allow the prepupae to climb out of the composter and drop into a collection area.

So you not only solve the problem of organic trash and shit but you also get a highly nutritive source of food. Their shit can be used to feed the red Californian earth worm thus producing even more food.

The only problem is that they aren't good looking so we might have to grind them and mix them in other food to make them less disgusting.

Yes, but the basic idea is that very little will be shipped from Earth, most stuff will be mined from asteroids/comets.

>> No.6131566

>>6131552
ALSO ALSO note that a larger mass of material/person - more open air, more open water - make an ecosystem MUCH more stable. Biosphere II was so unstable because it was so small; a larger volume of "wasted" space makes the biological closed-ecosystem component of a life-support system (and we WILL need a biological-ecosystem component; food chemicals are too complex to synthesize) more stable, enhancing the safety of the people there.

So, there's negative effects at work here - not only does greatly increasing the population density of the interior of an O'Neill cylinder not have a correspondingly large decrease in the cost of living per person, it also reduces the value of the real estate- the amount people are willing to pay- because it makes life there both less safe and less pleasant

Is it possible that these effects might cancel out, and there might actually be a plausible economic argument for relatively open-air space habitats?

(Alternatively, is it possible that either way, life in space will be too expensive for people to bother with?)

It's too expensive.

The Stanford torus, as an example, would weigh 10 million tons (most of which is the radiation shield, a 1.7 m layer of lunar soil.)

Right now, the lowest cost of space transportation is $2,200 per kg, from Earth to LEO. Since we're shipping from the moon, with mass drivers rather than rockets, let's cut that price by a factor of 100 - $22 per kilogram. (Since 95% of the material involved is literally Space Dirt, we'll assume the cost of gathering it is negligible.)

So, at this price, the habitat will cost 200 billion dollars to build - discounting labor costs, or the other 5% of material, which will be much more expensive and may have to be shipped up from Earth.

So: 200 billion dollars, to support 10,000 people.

What can these people do to pay that enormous cost back?

They can't mine, or farm, or produce resources - their ecosystem is closed-cycle, opening it up will bleed them to death.

Perhaps they have some manner of industrial capacity, then - an orbital shipyard, or something. Mineral refining from the Moon. A fuel depot for spaceships. Solar power collecting and beaming, something.

Maybe this actually makes them enough money to be self-sufficient: I don't know. I don't think anybody can really do those calculations as anything more than wild guess, right now.

But it is obvious that a Stanford torus, or one of these other habitats, can't possibly support itself by selling real estate - If we go by that 200-billion estimate, which we know is wildly wrong - in the optimistic direction, the real number is worse - if it has to pay itself back in 30 years, it'll cost each of its residents 670,000 dollars a year.

A couple of excellent points, thank you.
I am simply in the habit of providing myself room for failure and it serves me well. It would much more important in an environment like that.
Of course I have made a couple of unspoken assumptions such as that if a habitat is built in a place where environmental control is not to energy intensive (not to hot or cold) then building and maintaining a 1,000 cubic meter habitat costs little more than a 500 cubic meter habitat. Farming plankton would require little more than a big plastic bag full of water hung outside the habitat, etc.

Actually, because you're building a habitat in the form of a volume enclosed by a shell, habitable volume goes up as the 2/3 power of cost.

This means that building a habitat with twice the volume costs about about 1.5 times as much - not counting the cost of the air. which you'll need twice as much of.

So it's more cost-efficient per cubic meter of space to build a larger habitat, but it's not "little more" when we're talking about costs in the billions.

It would need to be capable of self-replication, for it to be a proper lifeform. Seems pretty implausible, as far as that goes.

Radiation wouldn't be impossible to handle - just like how long-distance spaceships would be shielded by containers of water or polyethylene or other low-Z materials, the creature would be wrapped in a layer of blubber and a water-storing sac, and outside of that would be hard carapace, perhaps covered in velvet like a deer's antler to help with growth and the radiation of waste heat. Plus, it would likely have a lot of DNA-repair mechanisms.

Metabolism would be slow, but just as a spaceship's passenger can have a working metabolism, this hypothetical Space Whale could have one as well.

Reproduction, and the re-supply of nutrient stores, could be tricky, though - you'd need some way for the Space Whale to actually eat, and it would quite definitely not be designed to live within an atmosphere or planetary gravity well. While it would rely on sunlight alone for metabolic energy, to repair wounds and make up for inevitable losses and wastage some re-supply of organic materials and nutrients would be necessary, and it'd need a lot of extra material to re-produce. Some materials it could perhaps scoop up by dipping into the very fringes of Earth's atmosphere, picking up traces of CHON, but I can't think of any way to work it without the Space Whale being dependent on resupply.

No getting around that in terrestrial (real) organisms either. Suppose a migratory cycle between the Oort cloud when they can feed on gasses, organics, small amounts of other elements they need from comets and other small bodies then they drift in toward the star where they use the energy collected to metabolize all this (gassing off some shielding on the trip maybe) and then slingshot around the star back out to the cold, comfortable outer system. The reproductive cycle would have to be synched up with this too of course.
About that, don’t forget some of the tricks organisms use to support reproductive efforts; the shell around an egg while it matures, a nest built by parents to protect the very young. “Milk” (whatever that might mean in this context)

First of all, not every space habitation is going to be in Earth-intensity sunlight all of the time. We need systems that work in lunar night, in the outer solar system, and in interstellar space.

Secondly, even when they're in sunlight of appropriate intensity, concentrated solar power is going to take much, much less mass, system complexity, and vulnerability to damage than exposing plants directly to natural sunlight in space.

Of course, not all of the synthesized sugar is going to go through plants. Some is going to be used to make synthetic processed food. Some will be used to grow cloned meat (which has the potential to be much, much more efficient to produce than feeding plants to animals).

Oh, that's why they are studying your method in the International Space Station and not planting vegetables... Nope!

Crew members aboard the International Space Station have been growing such plants and vegetables for years in their "space garden."

A space station study is helping investigators develop procedures and methods that allow astronauts to grow and safely eat space-grown vegetables. The experiment also is investigating another benefit of growing plants in space: the non-nutritional value of providing comfort and relaxation to the crew.

"Growing food to supplement and minimize the food that must be carried to space will be increasingly important on long-duration missions," said Shane Topham, an engineer with Space Dynamics Laboratory at Utah State University in Logan. "We also are learning about the psychological benefits of growing plants in space -- something that will become more important as crews travel farther from Earth."

It would be extremely slow to mine.
Consider: robots putting around out there with a big telescope to tell them where the good rocks are.
They go to it, grab it and throw it toward the inner system.
In the inner system someone scoops it up,
Replacement parts and other support for the Oort cloud machines are sent via solar sail.
The scheme has modest tech requirements (in this context).
It has very low energy expenditure but a very long time frame.

NASA is the only federal agency with less money than they had 20 years ago. They are running on a shoestring.
Good news: improvements in tech make projects that were estimated at 50 million USD ten years ago are now estimated at 10 million.

Here they clearly state that they plan on having plants and even going to keep CO2 levels higher to maximize photosynthesis.

>The level of carbon dioxide should be maintained below the OSHA standard (ref. 32), which specifies that pCO2 be less than 0.4 kPa (3 mm Hg). At the same time the CO2 levels will be high enough to permit maximum rates of photosynthesis by crop plants. Trace contaminants should be monitored and controlled to very low levels.

"Forever" as in "Rome will rule forever." or "Britiania forever". or "I will love you forever."
By "forever" you mean somewhere between 2 and 200 years.

We do it all the time.

But apart of that I think there are good chances that some big corporations might want to start exploring the space and expand there before all the others. The one who do that first will make satellites, telescopes, space travel and many more for a fraction of the costs of doing that on Earth and sending it to space. The main problem is the huge investment needed before start profiting.

So, 50 years into the future, people will socialize and give each other money to do things they think are neat. And they'll do it with computers working as electronic note-passers, like a very fast telegraph system that can send photographs and film clips and cheques as well as typed text.

Kickstarter: It's an investment scheme which works in the form of a pledge drive; people set up a message laying out their goals, asking for money, and providing rewards for certain-sized pledges. Kind of like a radio pledge drive, but you get to see pictures and video, and often the money is used to support - "kickstart", like a car -the creation of some new product. Because of the way the Internet interlinks everybody and enables word of mouth to spread incredibly fast and far, millions of people can see and donate to these "Kickstarters" and the most popular ones can raise funds in the tens of millions of dollars.

2013 dollars, anyway. There's been a lot of inflation. Still a lot of money, though.

As one of the few people around here from that era (admittedly, i was a little kid 50 yrs ago,) I would liken it to the telephone "party line" except with millions of people on the same line.

Again as a quazi-contemporary, what would be surprising is not the technology but its success.
