Since Trump won and he's going to MAGA can Space Elevator please come back. We're not a cynical as we were under Obama and the election is over.
Also if he was able to sticky a thread and have some sort of mod status I'd be up for that. Imagine coming to Sup Forums and having a Space Elevator sticky filled with inspiring dreams about the future of mankind and scientific breakthroughs that will change life as we know it.
If you support him reply with:
Space Elevator please!

He had a thread about a week ago, so I know he still comes around occasionally.
...
What the fuck I missed it?
He needs to be able to sticky his threads. This place moves way too fucking fast now.
Space elevator would slow the world down. Increase wobble
PLEASE
Not if you build two exactly opposite globally and erect them simultaneously.
SUMMON THE ELEVATOR
I am in agreement.
>inb4 muh flat earth
GET THE FUCK BACK HERE PLEASE
How the fuck would that work?
Building the equivalent of a skyscraper to space seems a bit ludicrous if you ask me.
I mean the highest we get isn't even a mile. And you want to go how high with this thing?
I doubt there is even enough material to build it. And even if there was how the fuck are you going to get to and from work building it? A fucking space helicopter?
No.
It's silly
AFTER IT'S COMPLETED, CAN WE SHOOT THE NOGS AND MUZZIES INTO SPACE AND MAGA?
I'll get right on to that for you, Mr Vulcan sir !
One interesting thing about the Space Elevator concept is that it serves as a mechanism for proving whether Trump is legitimately on the side of the American people or not.
Is it possible to build a space elevator today?
Yes:
youtube.com
The key idea is the Orbital Ring version of the space elevator, not the geosynchronous tether concept you are familiar with.
See, for example, Paul Birch's writings:
orionsarm.com
The orbital ring only requires tethers about 300 kilometers long which is technically feasible with common material like steel, but ridiculously straightforward with better and already available material like kevlar.
There are some important questions. First, how much would it cost to do something like this?
We need to send about 160 million kilograms of material into space (See Birch's boot strap estimates in part 2: orionsarm.com
We have rockets available at $2000/kg costs to LEO today in "mass production" mode, which is only about 10-20 launches per year. Compared with the couple thousand launches necessary for a space elevator, $2000 is an unreasonably high upper bound for launch costs.
We also need to include the cost of materials. A space elevator is about 98% steel and aluminum, 1% kevlar, and 1% other such as superconducting magnets. Most of the mass (98%) cost around $1/kg, with an average cost per kilogram of no more than about $10 per kilogram.
Summing the above up, we get about $430 billion in launch costs plus another $1-2 billion in material costs.
In other words, we can have a space elevator for less than $450 billion - significantly less than one year worth of DoD spending, one bank bailout, many times less than a variety of pointless wars, etc. This is well within our reach financially in other words.
We can build much higher than that. We just don't have a reason to.
There is some discussion in the Arab oil rich states of building a 2 and even 3 mile skyscraper. The main problem is not a matter of engineering, its of filling the building up with useful stuff and getting people moved quickly and in mass between floors.
What do we get in return for this $450 billion investment?
Virtually unlimited value. For example, with a space elevator we can reliably launch our nuclear waste into the sun. We've spent $100 billion building a waste repository in Nevada, but it was ultimately decided not to even use it. Now it costs only a dollar or two per kilogram to get rid of all of the nuclear waste in the world.
Second, we have immediate access to viable asteroid mining industry. Because the cost of delivering payloads to LEO drops to about $1/kilogram, we can not retrieve asteroids with trillions of dollars worth of minerals for mere tens millions of dollars in addition to having an easy viable way of returning those resources back to the surface.
We acquire the ability to deploy profitable solar power in orbit above cloud cover and with the ability to return said power back to the surface with near zero loss by running power transmission cables down the elevator.
Just how profitable?
With increased luminosity in space, enhanced exposure time, and the ability to deliver base loads, solar panels pay for themselves in only 1-2 years while having a 20 year life time.
In other words, if you put $5 trillion of solar panels into space, you get your $5 trillion back by the end of year two and a $5 trillion income stream each year thereafter.
In other words, the US could cut everyone's taxes, both personal and business, income, capital, death, or otherwise, all to 0%, not even cut any benefits or current spending, and pay off the national debt within a decade.
I know you
It should already be obvious that the entirety of the political debate spectrum is cointelpro.
Are taxes too high or too low? Irrelevant, we don't actually need taxes.
Is social spending bankrupting us? Irrelevant, we can retire the national debt without cutting spending all while having no tax whatsoever.
What does this have to do with taking the red pill?
We've had the technological ability to undertake such a project for decades.
That means all the squabbling you have heard your entire life, money, debt, spending, taxes, scarcity, whatever, is all bullshit. Not only is it bullshit, anyone with rudimentary knowledge of the world has known that it is all bullshit for all of this time.
In other words, once you come to understand the such a project is and has been technically feasible for decades, you have to reevaluate many things.
Why is there nothing of this in the conspiracy media? They are not really trying to expose or solve any problems. One hundred percent of it is cointelpro. From the Young Turks to Infowars or whatever, they are all completely full of shit because solutions to our problems not only exist, are easy to carry out, but this has been the case for a very long time.
Similarly, you now know that 20%+ annual GDP growth is possible. If Trump gives you 3-4% instead of Obama's 2%, he is simply working with the establishment to try to placate and subvert a rising tide. If we see the easily achievable 20%+ growth rates, it is at least possible that he isn't a subversive. Anything less and you know he is a fraud.
No, the end of the elevator will be in geosynchronous orbit, so that's wrong.
Meme calculations. Do you have any possible idea what multiple steel towers the size of what was put forth were would cost? We're talking on the order of tens of trillions of dollars at least, multiples of the world's liquid GDP, especially when you factor in how much steel/whatever material used would skyrocket in price due to the ridiculous and unheard of demand generated.
because of the change in angular momentum? why would it increase wobble?
>implying there arent solar arrays with 2-3 year payback that dont require 5 trillion in capex
>implying we need asteroids in 2017
He is not coming back.
Was that not an impostor just having a "space elevator" thread, if not pls gib archive link.

And what exactly do you plan on doing with this energy generated? At the moment there's no infrastructure whatsoever to allow us to constructively use it. It will just go to waste on power stations in space or go into batteries of spacecraft. Do you plan on beaming the energy down to earth? Well that's trillions of dollars worth of infrastructure we'd have to build in the first place, not to mention the potential accidents of frying large portions of the earth and killing untold numbers of people by mis-aiming a microwave beam by tenths of a degree.
Omg yaaaaaaaaa! I love you so much! Please get a mod login and make a weekly news update for us!
Yayayayayaya you give us dreams and hope!
Main problem I see is this will be a huge terrorism target.
That's why we gotta kill all the muzzies first.
Not hard to work around, considering the investment would be so mandatorily huge many nations would be involved in the construction process and after completion would likely provide an entire military fleet to defend it from land, sea, air, cyber, etc. attacks.
just imagine the cost, government projects always go over-budget.
But it wold be pretty easy to make if it was made in a disguises as an asteroid replant or some shit, heck i think in today's world even crowd funding is a possibility, you could use the orbit shifting elements as pro asteroid protection means. When the normies start to eat it up it wold be completed in a decade or less.
I think we'll hit 8% growth for the first time in a long time. With all our energy potential being unleashed and some regulatory rollbacks.
But we really need to keep pushing the limits of science in order to change the world and economy, like we did in the 1990's with the .com explosion.
We're so distracted as a public with social media that when a probe lands on Mars or something no one even pays much attention. We used to be captivated by these things. Why can't we have a permanent moon base? Or walk on Mars?
First off, your post contains obviously wrong information, i.e., the need to beam power back down. With a space elevator in hand, you have the ability to connect the power grid to space based solar arrays.
Second, there are endless applications for additional energy in the economy. Laser ablation of waste can solve our trash / recycling power. Abundant energy means we can shift farming indoors and prevent nutrient run off into the oceans, reversing a worrisome trend of increasingly depleted soil around the world. We can name countless pressing problems for mankind that are solved by higher energy throughput in the economy.
Alternatively, we can think of the benefit in terms of cheaper energy. With virtually unlimited high EROEI sources of power, anything with energy as an input (your home, car, food, gadgets, whatever) can fall in price - that is to say, you get more stuff and are better off.
drain the water from your head.
>not enough material.
u fuking fool
I think he went back to mexico
forbes.com
tfw it may be possible in 8 years to have a justifiably reason to build a SE in the first place. This is the greatest age to be alive.
With all that power we could afford massive amounts of salt water desalination to support the fresh water needs of future human populations.
It could potentially make rearranging atoms (turning lead into gold etc.) Economically viable as well since the cost of the energy is the main thing holding it back
$230 of power for less than $1 of gold iirc
Building a space elevator will actually lead to a terraforming of Mars rapidly thereafter. Once you have an elevator on Earth, it is cheaper to send an elevator to Mars than it is to send a small manned mission to mars currently.
Material costs for the elevator are only about $1 billion, the main expense being the $400B in rockets you need to get it into space.
But, then you have cheap access to space and can put all the materials needed for an elevator on Mars into orbit for less than $2B. We can put rail guns along the orbital rings to accelerate our payloads to Mars, requiring rockets only for slowing down / insertion into Mars orbit.
In other words, the few tens of billions projected as a cost to for a one time mission to Mars today could instead buy us a space elevator on Mars and therefore make colonization including return trips to Earth cheap and trivial.
I think the towers are supposedly made out of kevlar.
The guy does all the calculations. You don't even need that huge amount of raw material. It's less total steel/aluminum/kevlar than was in the world trade center. The cost is all in launching it into space.
That is correct. Mankind's need for energy is orders of magnitude higher than current production. Most of our major problems, conflict drivers, and uncertainty about the future are all mediated by the construction of a space elevator and the moving of mankind into a much higher energy throughput economy.
>we can shift farming indoors
phooey
Food should come form outdoors, think free range chicks etc. Plants need soil and connection to earth and natural weather. No chance to mimic this indoors.
kek, if he was smart as he seems he probably is making some top 10ns on youtube and getting massive bux.
I wonder why no user has taken up his mantle, how hard would it be to go trough all the scientific happenings of the week and make a qucik summary of them here with sources and up beat handwriting or grim warnings
whats the cost for clean up when muslims fly a jet into it at 400mph
Have they worked out how to deal with wind shear forces on it? Would be a shame for a tornado or high winds to topple it.
This is simply not true. Indoor farms present obvious benefits like the ability to prohibit undesired cross-pollination due to a controlled environment, more efficient water and nutrient use (no run off), the ability to deliver the exact amount of desired sunlight on any schedule, and perhaps most importantly, you no longer need pesticides and such. Being unexposed to the outdoors, a couple of bug zapping lasers and modest decontamination protocol entering the growing ozones is more than sufficient to prevent any pest infestation.
Look up hydroponics, aero ponics and their industrial applications.
It removes the biggest restraints that have always plagued farming: lack of space and uncertainty
Its on a barge that can relocate
>space elevator thread
>people actually discuss the feasibility of a space elevator
fucking newfags
>Plants need soil and connection to earth and natural weather.
You don't actually grow anything, do you? Without the threat of bad weather, pests, and with a perfectly controlled environment plants can thrive. You won't need to worry at all about leaf blights or other fungi. The only thing you need are pollinators, and even then most vegetables are self pollinating, or you can pollinate them with a paintbrush if need be.
I've literally masturbated plants with a fucking paintbrush when I needed them to pollinate. Plants don't need shit but good soil, light, and water.
A steel jacketed kevlar elevator has sufficient material strength to withstand placement in permanent Cat5 winds.
However, even if this were not the case, it wouldn't even prevent the idea from being viable.
The orbital ring can support dozens of elevators. Rather than the system being permanently locked in place (as would be the case with a ~40,000 km geosynchronous elevator), the orbital ring supports itself and the elevators can be detached and/or moved along the ring.
For example, the first 20 kilometers of the elevator could be supported by an inflatable structure that is retractable. The final ~180 kilometers to the orbital ring can detach from the first 20 kilometers in the event of bad weather, the first 20 kilometers being retracted to the ground for the duration of the storm.
Even ignoring all the challenges associated with building one in the first place, I've gotta ask, what exactly makes a space elevator better than a rocket, anyways?
This was the only tripfag I ever liked.
There is Japan Space Elevator Association
jsea.jp
It's a stupid idea.
We would first need to clean up all the debris around Earth before we even consider this kind of project.
Even if we did that, it's not like this would make it magically super cheap to move things to space, because it still takes the same amount of energy to move stuff up there.
Not to mention keeping such a thing up there, even under ideal conditions, is unfathomable with current materials. It would be fucking huge! The elevator would be many miles high, and if connected to a larger ring, would need to encompass the earth. And to keep the whole thing in place would require massive, massive, MASSIVE support structures, many of which would have to extend far below the ocean floor, just so it can anchor the damn thing (orbits decay over time, idiots). The sheer amount of material required to make it would be staggering.
Then there's the ongoing maintenance on this monstrosity.
vertical farming all the way, baby
What? Where are you going to get all this steel and whatever the fuck else you need. Screws and rope etc.
This isn't some magicians pocket you can just pull anything out of.
There probably isn't enough Steele in the entire galaxy to build this thing.
whut
I do not agree that indoors is better.
The problem is most efficient farming systems are largerly forgotten.
sciencedaily.com
"A global study, led by the University of Sussex, which included anthropologists and soil scientists from Cornell, Accra, and Aarhus Universities and the Institute of Development Studies, has for the first-time identified and analysed rich fertile soils found in Liberia and Ghana.
They discovered that the ancient West African method of adding charcoal and kitchen waste to highly weathered, nutrient poor tropical soils can transform the land into enduringly fertile, carbon-rich black soils which the researchers dub 'African Dark Earths'.
From analysing 150 sites in northwest Liberia and 27 sites in Ghana researchers found that these highly fertile soils contain 200-300 percent more organic carbon than other soils and are capable of supporting far more intensive farming.
Dr Dawit Solomon, the lead author from Cornell University, said: "What is most surprising is that in both Africa and in Amazonia, these two isolated indigenous communities living far apart in distance and time were able to achieve something that the modern-day agricultural management practices could not achieve until now."
Why on Earth would you want access to orbit for $1 / kg instead of thousands of dollars per kilogram?
Jokes aside, even if we had infinite money to waste on rockets, we would actually still want to build a space elevator. Why? Because rockets are just controlled bombs that no one has been able to build more reliable than about 97-98%.
That means that a few dozen trips to space gives you >50% probability of dying on a failed rocket. On the other hand, it is a trivial exercise to parachute down given a space elevator failure, meaning that people could take hundreds or thousands of trips between the surface, space, other planets, moons, and so on with better reliability than operating a car or some other mundane and relatively safe task.
Space elevators invite regular and reliable access in a way that rockets never will.
reaching orbit is half the trip, and with a space elevator, you essentially skip this step.
super duper cheap space travel, that is what this is about
Even if it broke at the base, the whole tether is in orbit. It wouldn't topple the whole thing; rather, the part below the break would fall and the part above would rise up into an elliptical orbit, dipping back into the upper atmosphere with every subsequent perigee. Depending on the strength and safety factor of the tether, you may be able to capture and reattach it.
I'm down... was thinking today about your other post and how it's scarcity/fear that drives the way the world is and switching to abundance and love (which would help if we remove scarcity) would be a good solution.
Anyway, let's do this. Where do we get started? Want to see more positive stuff on Sup Forums ... we all know the world sucks, let's make it better and weaponize that autism for good.
Main problemis the carbon nanotubes. We can only produce a fraction of an inch long ones. We would need thousands of miles of cable. Aslong as we can not figure this out there will be no space elevator.
did they not solve that with the spider web shit?
There is no material that is strong enough, light enough, and durable enough for the construction of a space elevator
Sorry mate
Indoor farming is the future. Been saying this for years, but everyone.just kept brushing it off. I guess they're all too enamored with FUCKING RETARDED-ASS SPACE ELEVATORS!
> because it still takes the same amount of energy to move stuff up there.
This illustrates a fundamental misunderstanding of why space travel is so expensive right now.
When you send something to space on a rocket, what you are doing is sending 1 kilogram of payload and 100 kilograms of fuel to an elevation of say a kilometer, then 1 kilogram of payload and the remaining 99 kilograms of fuel to two two kilometers, and so on.
In other words, you are paying the price to lift far more than your payload because you carry your fuel with you.
With an elevator in hand, your payload fraction is easily an order of magnitude larger than any rocket can achieve and therefore your energy requirements in excess of an order of magnitude lower.
No, you don't know what you're talking about, assuming an orbital ring made of construction grade steel, you can't beam the power down unless you incorporate a power system directly into the elevator structure, which will make it ludicrously more complicated, invalidating your idea that it will be cheap. Do you know how poor steel is for just beaming energy down? Especially steel used in industrial construction.
Orbital ring space elevator does not require carbon nanotubes because the elevator only needs to be a few hundred rather than 40,000 kilometers long.
In fact, you could build a space elevator with tapered steel using the orbital ring design. There is no reason to use steel rather than lighter materials with higher tensile strength like kevlar, but it is in principle strong enough.
Space Baiter please!
No. The spider web shit is not strong enough anyway and for the orbital ring we would need to carry alot of mass into space every day we would need to start multiple rockets for decades.
JET FUEL CAN'T MELT STEEL BEAMS
The small-minded fools at NASA rejected my space escalator idea.
Do we finally get Mobile Suits too?
bro ur img is watermarked with the pedo symbol
Why ?
Mass produced housing unregulated is needed here on earth first!
>Without the threat of bad weather, pests, and with a perfectly controlled environment plants can thrive
Totally wrong. You get biomass, sure. That's all.
How many million tonnes would we need for a ring. It also needs to go around the earth.
>incorporate a power system directly into the elevator structure
That's right, you just run electrical lines down the elevator and tie into the grid. It is no different than connecting solar panels on your roof into the grid. High voltage DC transmission lines exist on Earth that are over 1000 miles long, far in excess of the length of the space elevator. Easy stuff.
Do you know how fucking expensive kevlar is? Not to mention you're completely ignoring the economic externalities associated with this. If we produce an entire space structure out of kevlar then we are literally producing more kevlar than has ever been produced on the planet by orders of magnitude. Do you know what this increased demand will do to the price of kevlar? It will increase by possibly tens of times, meaning that the rudimentary calculations can't reasonably be expected just to be trusted at face value.
Indoors is better for the simple fact that your growing season is now "yes" instead of "sometimes." This is useful for any crop, but affords especial utility to high-margin foodstuffs like strawberries and tropical fruits.
hell the fuck yeah
If digits then we will by the end of the year.
You need about 200 million kilograms of material for a small orbital ring. By 'small' we are talking about able to support ~20 different elevators around the world each with 300 kg/sec throughput capacity or 200 billion kilograms per year.
Calm down kid literally noone here has any idea what they're talking about and we don't care
The idea is that because a large portion of the elevator is in space it supports most of the weight enabling you to have your choice of foundations.
Apparently the most feasible one is a barge in the ocean.
A single elevator would weigh about 100,000 kilograms, not all of which is kevlar.
In comparison, annual production is in excess of 50,000 tons - about 500x what we need for an elevator.
As is usual, the naysayers are simply slinging outright lies to try to discredit the idea.
DAILY REMINDER THAT Sup Forums HASNT BEEN THE SAME SINCE SPACE ELEVATOR LEFT
Fucking carbon, it doesn't work (so they say.)
Well then you're completely lying about the costs being so cheap then, that dramatically increases the costs of the project, it's one thing to just build massive steel support structures, it's entirely another to build entirely self contained power cables. Not just this, but incorporating DC lines into the structures themselves will decrease the tensile strength of the structure overall meaning you'll need more steel or stronger, more expensive materials and the costs will further increase.
Space Elevator please!
Well, this thread shows how new most of Sup Forums is.
wouldn't be the same due to the inevitable bias that would show through somehow
Id love to see this pretend, not very good, Space Elevator imposter arguing with a contractor about going over bid on his remodel :)
The "Grow Local" movement is helping to agitate for food growing buildings in cities. Some hope a few skyscraper vertical farms could be operated inside cities allowing a city to actually feed itself, rather than be dependent on food being shipped in from around the country/world.
Space Elevator!
But the increased cost would be offset by the ability (theoretically) to generate amounts of power limited only by your imagination.
Profitably too
The problems with such a giga-engineering project (the elevator isn't the problem, it's the rocket infrastructure, as you mentioned) isn't purely economical. The legal issues alone are a big deal for the contract-crazed USA.
