I'm thinking that if we're going to survive certian cataclysmic events like a loss of the Ozone layer, Nuclear War, Biological War, Viral flu's and other many events like Economic collapse we will need to build a sustainable and dependable environment for which to live out our lives.

 

Obviously significant hurdles exist. Like Telecommuting for work, Providing sufficient healthcare for an entire population, planning of the entire underground city, selecting the right ground to start digging in, legal and government planning permits, financial.

 

I hope to create this thread to get the idea rolling and see just how feasible it is.

 

I think that this is the most important thing that we can do for the human race, both now and in the distant future. Even if it takes a hundred years, we should be able to all do it together. At the very least see if its possible.

 

I'm thinking something like this: (The Ocampan Underground Home in Star Trek Voyager S01E01)

Yes, but one of the most abundant natural cataclysmic events are earthquakes so being in an underground city would not make me feel very safe.

In the case of a global catasthrophe whatever kind of city you build, it is probably going to get overrun.

The high, vaulted ceilings would make seismic events very devastating, but if one were to build the underground city in naturally formed caverns which are of appreciable antiquity that would lower the chances of it all collapsing in on itself. However, I'm not sure that Australia has any vast underground cavern systems. Those that exist are probably either parks or otherwise government land and would be off-limits to actual habitation.

What about a large cavern or meteor crater? Closer to the surface with manmade caverns and homes built inside reinforced caves tunnelling through the surrounding ground?

 

Pick one:

https://en.wikipedia...rs_in_Australia

 

Possibly even creating a meteor crater artificially by dynamite/tnt.

 

You could make the columns completely artificial, then cover them with something that looks natural, with a glass roof ontop.

 

Then build a supporting city on the outside of the crater. Then use the resources from everyone to create another artificial crater using earthmoving equipment.

 

Then join the two with tunnels, train transportation.

 

Just FYI, Australia is mostly inert when it comes to earthquakes.

 

Also, we could build it close to the topsoil and make a glass roof which would effectivley create a fast growing greenhouse effect year round, increasing crop yeilds.

I think this is a great idea, and one that I have been thinking a lot about. My perspective is that of run away climate change.

 

People don't realize it but actually the greatest threat (among many other threats) to humanity is that of thermal body regulation (thermogeddon). As global temperatures rise so will humidity. As humidity rises the body's ability to regulate temperature goes down. This has not generally been recognized as a problem, because it hasn't really happen before. 

 

Why if it hasn't happened before should we worry about it now?

 

Given the situation with arctic temperature anomalies and their effect on the methane hydrates,  and the way that fracking is now being used in the tundra, it is inevitable that there will be increased methane releases. With green house gases (ghg), C02 is not the problem, methane is (or will be). Methane is a much more potent ghg than C02. At some point, this is going to get out of hand. 

 

The problem of the thawing methane hydrates is that they have been previously analyzed as slabs. In a nutshell the model states you have to thaw the top layer for the next layer to be affected, consequently it happens over thousands of years. But that does not take into consideration earth quakes or tremors. That is where the danger of fracking lies. The only people denying that fracking causes earth tremors are the people who are doing it. They are cracking the slab model. That allows lower levels to release methane to the surface. For more information google "methane water fracking Texas".

 

The only way to cope with an average temperature rise that produces deadly extremes is in a place where the temperature extremes are avoided. That place is either heavily air-conditioned, underwater or underground.

As I see it the problem with relying for survival on air-conditioning is if it fails. It takes a lot of solar panels as a backup system to support even a small air-conditioner.

Underwater is a huge costly project.

Derelict mines (non-toxic), caves or Coober Pedy style excavations seem to be the only options. Caves can be defended, cooling power consumption is minimized and food can be produced outside in the winters.

 

Simply running off to hide in caves for a few hot days would be a short term fix. The larger problem is that of society's infrastructure and our lack of preparation for change. Whether people believe in climate change or not, the impact is starting to be felt at the supermarkets. We are totally reliant on an interconnected world. Everybody has specialized. Once those connections begin to break down we will be totally unprepared and there will be no local expertise to help us out.

 

In Australia the amount of arable land is minimal and we keep paving over what we have left. It seems to me that the way to go is to start a culture that relies on its economic survival by producing food, using a combination of hydroponics and aquaponics, for sale into cities. As climate change and the changing Asian diet continue, the value of food commodities will increase making the culture economically stable.

 

I say culture, because there is simply no way that our actions are going to influence the global environmental situation so that we can have an orderly transition. Scientists and activists have made small gains but they are gradually being silenced. That is, the current economic and political situation favors oil and gas companies. Money controls propaganda and the politicians. Nothing is going to change anytime soon.

 

Once the environmental situation becomes so bad that the general population demands change, it will be too late. Modern civilization would have to shutdown, but the larger problem is that the ghg have a long shelf life. Shutting down civilization would stabilize the C02 component of ghg, but the warming caused by ice loss albedo, and stabilized water and air heat would already be thawing the top level of the methane hydrates. It is a runaway event.

 

So shutdown civilization and use dangerous geo-engineering to fix the situation. But, this is assuming civilization can shutdown. How can civilization shutdown, when most people live in the cities. They can't grow their own food and it is too bloody hot to turn off the air conditioner? Fine, build thorium reactors. Only trouble is that they take political will, money and a long time to build. How much time do we have?

Hi Paul,

Welcome to Longecity/Imminst. I agree with you, except I think food insecurity/mass starvation will hit more people sooner than the thermal body regulation problem. Either way sucks.

 

I'm pretty sure this is the way the world will end (for humans) and it may happen in my lifetime or shortly after my time is up. I wish I had realized this before I decided to reproduce, but at the time I still thought we had a chance, and we may have, but no one in power did anything.

 

That said, you should try, if you can. I think it would take a lot of money to do what you want/need to do to make it work. Growing enough calories to live on is actually difficult if you don't have arable land to work with. I love hydroponics and green house growing, but it is harder than you might think, and it would be even more difficult under this catastrophic, end-of-civilization scenario.

Hi Lemonhead,

This may be a bit of a long post.

 

I absolutely agree that along time before we hit thermogeddon, society will break down. One study puts it at 20 years, a lot depends on a destabilizing climate. Collapse needs to be prepared for very carefully, and the only way I can see that happening is through community. There is strength in numbers. In fact, without distributed communities, collectively we will descend to become cave dwellers fighting for scraps.

 

In terms of calories and protein there are a number of ways that a small amount of space can be made highly productive. As an example, with a small amount of power a lot of mushrooms can be produced all year. They are very good for you, don’t need much light and are extremely efficient feeders.

 

Traditional outside agriculture will be turned on its head. Winter will be the time of planting, summer the time of rest. There are some big problems however, soil temperature can negatively affect microbes and the bees would probably be gone. Storms will be a huge concern.

Microbes can be aided with sprayed aerated compost tea. Hand pollinating works. We definitely aren’t talking mass produced plant monocultures.

In terms of hydroponics the challenge would be the nutrients. When the global logistics system breaks down then sourcing the hydroponic nutrients would be a problem. I have tried worm compost tea and it works. But there are special engineering requirements, also you can’t run this indoors - it stinks!

That is what makes aquaponics so compelling. A protein source that produces nutrients suitable for plant growth and doesn’t smell.

 

In addition, what may currently seem unpalatable may well have to be reconsidered. From insectsAreFood;

100 grams of cricket contains: 121 calories, 12.9 grams of protein, 5.5 g. of fat, 5.1 g. of carbohydrates, 75.8 mg. calcium, 185.3 mg. of phosphorous, 9.5 mg. of iron, 0.36 mg. of thiamin, 1.09 mg. of riboflavin, and 3.10 mg. of niacin.

 Compare that with ground beef, which, although it contains more protein, about 23.5 g. to be exact, it has 288.2 calories and an enormous amount of fat, 21.2 grams worth.

Crickets are 500% more efficient feeders than are cattle, and reproduce much (much) quicker. An added benefit is that they can be raised from plant waste.

 

A single failure could destroy the community so no room for error, 2 or 3 separate concurrent systems at different locations.

 

Survival during summer is then about how much preparation was done during winter. Bottling and drying, just like it used to be done for winter.

 

However even with the right technologies, very few communities survive long term without religion and cultural practices that give the community a sense of identity and moral structure. I am going to make sweeping generalizations here but modern religion is found at the mall. Buddhist practice in the west has become so watered down that it is nothing more than feeling peaceful (not saying that’s a bad thing). Christianity is now about mega churches and is a far cry from what the 1st century gnostics had in mind. True Taoism is lost in antiquity. Islam, during the dark ages, was the refuge of science, we would not have the number 0 or algebra without it. But it became rigid to the point where they burned down the library of Alexandria. The Hindus seem to have become stuck in a plethora of gods and ritual.

 

So the garden of Eden has been lost, finding it again is near impossible. There are some who know the way back, but most people really aren’t interested in looking. There is no fear of God/Allah/Buddha/White buffalo women/(insert name here). That is the greatest threat to any isolated community, without government mandated law and order. Reminds me of the book “Lord of the flies”.

 

What community would survive 1000s of years? The Israelis seem to have done it with a simple fixed set of guidelines. It essentially segregated them, in a volatile fluid part of the world. I think the idea with circumcision was brilliant, "Hey you're not one of us, get that thing away from me". Just saying ... not recommending :)

So there has to be a constitution, the threat of exile would be enough.

 

Another big issue is skills. We have forgotten how to survive outside the machine. Humanity cannot afford to lose that knowledge. We have built a huge wealth of knowledge and it is crucial that it is preserved, currently it is stored in hyperspace. When the wars break out hyperspace will be the first strike. There were 8 million botnet connections in the last 14 days and that is nothing unusual. Just as there are seed banks there needs to be offline knowledge banks. DIY tutorials, university courses in Electronics, Agriculture, Food, Engineering you name it.

 

Finally, there is the issue of the tragedy of the commons. There is no way to avoid it, and we are seeing the effects of it all around us. Individuals acting in their own best interest will deplete the common resources. I am not a communist, though you have to question the supposed benefits of democracy. Democracy has been usurped by the rich. They own the media, they own the corporations. Massive funding is required to get elected and that funding is coming more and more from the rich. They direct that funding to the people that best serve their interests.

 

The poor and old are not supported, few can afford hospitals, forests are felled, rivers are polluted, the air is toxic, and the aquifer water is fouled. Just to name a few. The environment is fundamental to life. It is not something to be bargained with, it is owned by each and everyone of us. 97.1% of scientists agree on the state of the environment. Yet, we are incapable of doing something to stop its collapse. Therefore there is only one conclusion. This system is fatally flawed.

 

The root cause of the flaw is that, left to its own devices, humanity is dim-witted and short-sighted. None of the great people of history, Gandhi, Jesus, Gautama Buddha, Mother Teresa to name a few, achieved what they did naturally. It was not second nature, they subjected themselves. “Not my will, but yours be done”

The meek shall inherit the earth, after the willful destroy it.

 

Never in the history of humanity has there been a time more critical than this one. Even during the cold war with fingers hovering over ICBM buttons, there was opportunity for negotiation. We don’t even get that luxury. A disintegrating future is locked in. The eventual scenario seems to be that 9 billion people will fight for survival on a planet that can sustain 1 billion.

 

I may not be around to see that day, but my kids will be. So this would be building something, not for me, but for the next generation. I have no misconceptions, this is a huge task, but there is a way of making it happen. “A wise old man plants trees he knows he will never get to sit under”.

There is a lot more I could add actually a books worth, particularly regarding the technology side and how to make the community profitable, but I don’t want to bore anyone with what may be perceived as a bunch of hot air. I believe it is possible, but the socio/economic/physical environment will be extremely hostile. Without ample preparation, there will be little chance of success.

I agree with you for the most part. I 'm just a lot less optimistic about the feasibility. I'm a pessimist by nature, but perhaps I would not be so if I had the means to actually work on these problems. Due to various life circumstances, I've been forced into a state of 'learned helplessness'. So basically, don't listen to my negativity, just listen to my warnings of potential pitfalls and find ways around them.

 

Mushrooms, insects, I'll eat 'em (I rather like mushrooms) but the calories for heterotrophs have to come from somewhere - namely fixed carbon, fixed by photosynthesis. You need lots of light for that, water, the right temperature range, CO2 (which the atmosphere will have but you need ventilation systems for enclosed spaces), and of course macro- and micro-nutrients. You've done some growing, that's good, just keep in mind the scale. Can you reliably generate at least 1500 kcal a day for each person you want to sustain?

 

There are some books about building 'survival greenhouses'; one of the early ones was by James B. Dekorne, which he later revised and published as The Hydroponic Hot House. I liked this book because the author acknowledges mistakes along the way; he seems honest and isn't trying to fear-monger or over-inflate his successes, as do some of newer books on the subject.

 

As far as religion during a breakdown of civilization goes, Octavia Butler's Parable of the Sower has some interesting ideas.

 

Keep growing, keep working, and good luck.

Hi Lemonhead,

Yes, there are a lot of issues that need to be worked through carefully. I'll try and split up my thoughts on it a bit.

 

Growing outdoors

Winter time would have its own growing season. Even in a 10C average rise scenario in my region that correlates to a winter time high of 20-25C. So growing from autumn to spring is feasible. That could be done in plowed fields if the soil was not degraded too much. Which brings us back to spraying aerated worm compost tea to regenerate the soil. During summer outdoor growing would be limited to edible cacti and succulents. There are a lot of choices there. In my climate I would see an average rise in summer to 50C, cacti are made for that.

 

Growing indoors

You are right, there is light requirements and ventilation. The first step is to select low light edible species. There's a list of about 40. The next step is to get light in without the heat. Grow lights are an option, but only if connected to the grid. The cost of running them would be prohibitive.


Piping sunlight indoors is much cheaper. However, by lighting the indoors the interior temperature must not be affected.

Growing indoors has proven to be successfully done via fibre optic cables. Using a heliostat outside to capture the light and concentrate it into fibre optic cables is feasible, but expensive.


A simpler approach would be to use light tubes (skylight). If there is a vertical shaft then the top can be sealed with perspex and the sides lined with silver sarking (reflective insulation). Frosted glass or a Fresnel lens diffuser could be used at the interior end to disperse the light. One shaft would not be sufficient. The design of the shaft top would be important to maximize the light, while requiring minimal automation.

 

Ventilation really depends on location. Obviously natural cross-ventilation is best. A tunnel with open ends and light shafts would work. During heat waves the ends would be closed and opened at night. C02 is heavier than air so that should affect the design.
Automated systems require power, if that was the case a solar powered fan could be used. External air could be pumped in through a channel in the ground (to cool it) to the apex of the grow room. That way fresh air would displace C02 from the top of the room.

 

So I believe that it is possible to provide enough food if, as you say, the calories are measured correctly. The challenge will be having the time and finances to set it up prior to any sort of panic. That is why this has to be done with a business model that would work in the short term. Location is also very important as being too isolated from potential clients would create logistic nightmares, being too close would create (additional) problems with affordability.

 

Anyway thanks for your comments, it is good to work through these processes.

Heliophobes will love this idea! I am a moderate heliophobe now but used to be a huge huge one, so anytime anything comes along which involves humans living underground, or driving in cars like in Breaking Dawn, or becoming a society where full face gear is acceptable, I take notice. My heart doesn't leap up like Wordsworth anymore, but I am just permanently attuned at this point to noticing the heliophobe benefits of these types of possibilities.

Actually I had a brain dead moment. You don't need to get rid of C02 in a greenhouse, plants love it. I actually have a C02 regulator. Jeeze, I have spent so much time researching climate change I am forgetting the basics. Generally, enriching the garden's air to raise the level between 1,000 and 1,500 ppm C02 is recommended.

Plants love CO2, but they also need O2 for respiration. A lot of growers do things to up CO2 in enclosed environments, especially during the day/light period, but what's optimal depends on the plant species. I suppose altitude/atmospheric pressure matters to plants, just as it does to humans and other animals.

 

Biosphere II experienced problems with unexpected fluctuations in CO2 and low O2 levels. It was an interesting experiment, but I think misguided in the attempt to re-create representative biomes; they should have focused more on just creating a self-sustaining system.

 

As far as winter growing outdoors goes, you might be able to do it in Australia since you are for the most part at lower latitudes than here in the US. I found a copy of the Dekorne book at the library; even though he was down in New Mexico (35 degrees latitude) he still did not get much production for much of the winter since he did not provide a lot artificial lighting. Here's a quote: "The concept of the effective growing season is one of the most important points made in this book, and it can hardly be over-emphasized: Under ordinary circumstances, plant growth during deep winter in most sections of the Unites States, will not result in enough edible tissue to justify the effort or expense of cultivating it. You can keep your tomato plants alive over the winter period, and you may harvest a salad or two from your lettuce plants, but food-production levels during the period of October 21st to February 21st will probably be but a pitiful fraction of what you'll harvest during the rest of the year."

 

The newer LED grow lights may offer a solution to the lighting issue for indoor growing since they are so efficient, but if civilization collapses,  you won't be able to go online and order more when you need them. Well, I guess the same is true for pumps and all other manner of equipment.

 

Another consideration for outdoor growing is that changes in photoperiod are often required to trigger reproduction in plants, and we mostly eat reproductive parts (grains, beans,fruit), so simply moving up latitude for summer growing may not work for some major food crops. Plant breeding might be able to address this issue, but it takes time, even using genetic engineering techniques. Sweet potatoes may not be a problem since we eat the tubers (and they are the most productive crop per unit area.)  hmm... just googled it, tuber production is influenced by photoperiod

I agree with you regarding the Biosphere. In the end I believe it was the type of cement that did them in. Apparently the human relationships weren't going that well either. A model that looks more favorable is the Eden project in England.

 

Your point regarding photoperiod is interesting. I tend to focus on winter crops in my (small) greenhouse during winter so I hadn't taken that into account. I wonder how much of Dekorne's experience was related to the actual temperature during winter. Interesting generalized chart...

s-curve.gif

Boston lettuce (as well as other lettuce cultivars) forms full leafy heads when the daily growing temperature is in the 10 to 15oC (50-60 oF) range. 

 

But, as you have stated, the photoperiod is essential for flower formation. LEDs could supplement the light period, provided that the logistics chain stays viable. And here I think we are at the crux of the problem and its solution.

 

If the logistics chain completely breaks we are gone. But I don't believe the elite will easily accept that. They will do whatever is required to survive, often with many evils resulting. A lot of what the future holds for the rest of us will be determined by how well we are prepared to meet it. This will be a devastating shock to mankind. That is unavoidable now, but many examples do exist of how resilient humanity can be. With no geopolitical opinions implied, Palestinian and North Korean tunneling are examples. When faced with disaster humanity can be co-operative and inventive. 

 

Our society is highly specialized. Either way, with or without, adequate planning the toll will be very high. The issue is whether we can survive. The provided basic supply channels remain open, the answer for replacement parts lies in 3D printing. Over the next decade there will be few things that cannot be replicated with 3D printing provided you have the raw materials and the know-how.

 

If enough people join together some of the pending disaster can be avoided. By that I mean that a form of civilization can be retained. Perhaps culture could actually benefit in that very important lessons could be learned. But, I must say, humanity is not very good at mitigating pending disasters. As a species we seem to be more reactionary. Which, given the circumstances, is unfortunate.

Dekorne was unable to maintain an average low temperature above 40 deg F for four months of the year in his pit greenhouse, which was heated just by passive solar. (He later states that he now prefers the attached greenhouse design since it helps with home heating).

 

He writes:

 

"Figure 5-1 shows the pertinent mean temperatures for each of the zodiacal months of the 1973-1974 year - which was a typical season in this area. The average low temperatures are graphed in Figure 5-2. As you can see, the magical 40 degree F low temperature does not appear until Aries (March 21 to April 21). As mentioned earlier, however, I found that cool weather plants (lettuce, spinach, etc.) began to thrive a full month earlier - around Feb 21. The attentive reader will also note that the mean temp for Scorpio (Oct 21 to Nov 21) is 41 deg F - in theory, a temp capable of providing another month of growing beyond the Oct 21st cut-off point. The fact that plant growth ins negligible during this period indicates the effects of a waning photoperiod."

 

This is an important idea to get across, particularly here in North America, since some people seem to believe that if it becomes too hot or dry (or perhaps even too wet in some places) in the summer to grow crops, farmers can simply shift the growing season. Or at least, that's the type of thinking I encountered when teaching an introductory environmental studies class to non-majors a few years ago.

 

Some random information that might be helpful:

Researchers Create Powerful Muscles From Fishing Line, Thread

"The research team also has demonstrated the feasibility of using environmentally powered muscles to automatically open and close the windows of greenhouses or buildings in response to ambient temperature changes, thereby eliminating the need for electricity or noisy and costly motors."

 

Perhaps what is needed is a cool house instead of a hot house. The pit design might be useful. Special material for the glazing that lets in photosynthetically active radiation but blocks out the rest. A heat pump. Stuff like that. This would all have to be able to last a long while, though. High winds, hail, tornadoes, hurricanes would all be very bad things. hmm... perhaps I should stock up on fishing line...

 

 


If enough people join together some of the pending disaster can be avoided. By that I mean that a form of civilization can be retained. Perhaps culture could actually benefit in that very important lessons could be learned. But, I must say, humanity is not very good at mitigating pending disasters. As a species we seem to be more reactionary. Which, given the circumstances, is unfortunate.

 

Yup.

Hmm, that is interesting indeed regarding the temperatures. I have not experienced that, but that might be for a reason. My growing space is filled with water. I set it up trying for hydroponic simplicity and inadvertently may have given my plants an edge. Under all the pots are tubs/tanks that are connected together using siphons. The consequence has been a decent thermal mass. It is an attached greenhouse, in winter on a sunny day it is actually quite warm. So it is possible that the space is actually significantly warmer at night than other spaces might be. .

Water has another use that could be handy in making a coolhouse. As the temperature differential between air and water increases, the water by pulling heat from the air. So all that is required is to decrease the temperature of the water in a separate space. In theory, by cooling the water it would pull more heat from the air. A few options might;
Running coils through a chest freezer on a timer which would be fairly efficient. Though the freezer would pull a lot of power during its on phase.
If the humidity is low enough you can cool the water via a Coolgardie safe type of setup.
Last in my list would be if the water volume is sufficient you could allow the heat to build up and then release it at night using a fan powered car radiator, preferably outside. I did that once with a leaking pressure valve on a hot water heater. Except that time I used it to heat the grow space. Worked a treat.

Regarding the vents, you can buy them on ebay (Search auto vent greenhouse). Works via a different process though the outcome is the same.

We are heading into winter here. From now on I will try and be more scientific in my research regarding the temperatures experienced here. However, antecdotally, this might not be the best test for other colder climates. The current forecast is for 18-20C for the next week which is 3-4C above average. I saw someone over in NZ mention strange weather there too. The tomatoes will be the canary in the coal mine, normally in my climate the seedlings should be transplanted in November, I did them 2 weeks ago. Everything I have recently planted is going great guns. 

I have to say the more I look at the rate of climate change, the more I am concerned. This is change at a planetary scale, and it is not occurring in a linear fashion. By the way noticed you are from Raleigh, NC. I spent a while in Rocky Mount (relatives there). Beautiful part of the world, wonderful people.

I tried posting the images here, but I got You are not allowed to use that image extension on this community.
