Gulches — freedom lifeboats

Posted by in categories: education, geopolitics, habitats, lifeboat, nuclear weapons

Jim Davies of Strike the Root writes about Galt’s Gulch and some gulch-like projects. These appeal to him because of the exponential trends in government power and abuse of power. He writes, in part,

“We have the serious opportunity in our hands right now of terminating the era of government absolutely, and so of removing from the human race the threat of ever more brutal tyranny ending only with WMD annihilation–while opening up vistas of peaceful prosperity and technological progress which even a realist like myself cannot find words to describe. ”


Avoiding those terrible events is what building our Lifeboat is all about. Got Lifeboat?

I Don’t Want To Live in a Post-Apocalyptic World

How About You?
I’ve just finished reading Cormac McCarthy’s The Road at the recommendation of my cousin Marie-Eve. The setting is a post-apocalyptic world and the main protagonists — a father and son — basically spend all their time looking for food and shelter, and try to avoid being robbed or killed by other starving survivors.

It very much makes me not want to live in such a world. Everybody would probably agree. Yet few people actually do much to reduce the chances of of such a scenario happening. In fact, it’s worse than that; few people even seriously entertain the possibility that such a scenario could happen.

People don’t think about such things because they are unpleasant and they don’t feel they can do anything about them, but if more people actually did think about them, we could do something. We might never be completely safe, but we could significantly improve our odds over the status quo.

What should be at the center of the U.S. stimulus package

Posted by in categories: existential risks, geopolitics, habitats, lifeboat, space, sustainability

The projected size of Barack Obama’s “stimulus package” is heading north, from hundreds of billions of dollars into the trillions. And the Obama program comes, of course, on top of the various Bush administration bailouts and commitments, estimated to run as high as $8.5 trillion.

Will this money be put to good use? That’s an important question for the new President, and an even more important question for America. The metric for all government spending ultimately comes down to a single query: What did you get for it?

If such spending was worth it, that’s great. If the country gets victory in war, or victory over economic catastrophe, well, obviously, it was worthwhile. The national interest should never be sacrificed on the altar of a balanced budget.

So let’s hope we get the most value possible for all that money–and all that red ink. Let’s hope we get a more prosperous nation and a cleaner earth. Let’s also hope we get a more secure population and a clear, strategic margin of safety for the United States. Yet how do we do all that?

Refuges and bunkers

Posted by in categories: asteroid/comet impacts, cybercrime/malcode, defense, existential risks, habitats, lifeboat, sustainability, treaties

Here I would like to suggest readers a quotation from my book “Structure of the global catastrophe” (http://www.scribd.com/doc/7529531/-) there I discuss problems of preventing catastrophes.

Refuges and bunkers

Different sort of a refuge and bunkers can increase chances of survival of the mankind in case of global catastrophe, however the situation with them is not simple. Separate independent refuges can exist for decades, but the more they are independent and long-time, the more efforts are necessary for their preparation in advance. Refuges should provide ability for the mankind to the further self-reproduction. Hence, they should contain not only enough of capable to reproduction people, but also a stock of technologies which will allow to survive and breed in territory which is planned to render habitable after an exit from the refuge. The more this territory will be polluted, the higher level of technologies is required for a reliable survival.
Very big bunker will appear capable to continue in itself development of technologies and after catastrophe. However in this case it will be vulnerable to the same risks, as all terrestrial civilisation — there can be internal terrorists, AI, nanorobots, leaks etc. If the bunker is not capable to continue itself development of technologies it, more likely, is doomed to degradation.
Further, the bunker can be or «civilizational», that is keep the majority of cultural and technological achievements of the civilisation, or “specific”, that is keep only human life. For “long” bunkers (which are prepared for long-term stay) the problem of formation and education of children and risks of degradation will rise. The bunker can or live for the account of the resources which have been saved up before catastrophe, or be engaged in own manufacture. In last case it will be simply underground civilisation on the infected planet.
The more a bunker is constructed on modern technologies and independent cultural and technically, the higher ammount of people should live there (but in the future it will be not so: the bunker on the basis of advanced nanotechnology can be even at all deserted, — only with the frozen human embryos). To provide simple reproduction by means of training to the basic human trades, thousand people are required. These people should be selected and be in the bunker before final catastrophe, and, it is desirable, on a constant basis. However it is improbable, that thousand intellectually and physically excellent people would want to sit in the bunker “just in case”. In this case they can be in the bunker in two or three changes and receive for it a salary. (Now in Russia begins experiment «Mars 500» in which 6 humans will be in completely independent — on water, to meal, air — for 500 days. Possibly, it is the best result which we now have. In the early nineties in the USA there was also a project «Biosphera-2» in which people should live two years on full self-maintenance under a dome in desert. The project has ended with partial failure as oxygen level in system began to fall because of unforeseen reproduction of microorganisms and insects.) As additional risk for bunkers it is necessary to note fact of psychology of the small groups closed in one premise widely known on the Antarctic expeditions — namely, the increase of animosities fraught with destructive actions, reducing survival rate.
The bunker can be either unique, or one of many. In the first case it is vulnerable to different catastrophes, and in the second is possible struggle between different bunkers for the resources which have remained outside. Or is possible war continuation if catastrophe has resulted from war.
The bunker, most likely, will be either underground, or in the sea, or in space. But the space bunker too can be underground of asteroids or the Moon. For the space bunker it will be more difficult to use the rests of resources on the Earth. The bunker can be completely isolated, or to allow “excursion” in the external hostile environment.
As model of the sea bunker can serve the nuclear submarine possessing high reserve, autonomy, manoeuvrability and stability to negative influences. Besides, it can easily be cooled at ocean (the problem of cooling of the underground closed bunkers is not simple), to extract from it water, oxygen and even food. Besides, already there are ready boats and technical decisions. The boat is capable to sustain shock and radiating influence. However the resource of independent swimming of modern submarines makes at the best 1 year, and in them there is no place for storage of stocks.
Modern space station ISS could support independently life of several humans within approximately year though there are problems of independent landing and adaptation. Not clearly, whether the certain dangerous agent, capable to get into all cracks on the Earth could dissipate for so short term.
There is a difference between gaso — and bio — refuges which can be on a surface, but are divided into many sections for maintenance of a mode of quarantine, and refuges which are intended as a shelter from in the slightest degree intelligent opponent (including other people who did not manage to get a place in a refuge). In case of biodanger island with rigid quarantine can be a refuge if illness is not transferred by air.
A bunker can possess different vulnerabilities. For example, in case of biological threat, is enough insignificant penetration to destroy it. Only hi-tech bunker can be the completely independent. Energy and oxygen are necessary to the bunker. The system on a nuclear reactor can give energy, but modern machines hardly can possess durability more than 30–50 years. The bunker cannot be universal — it should assume protection against the certain kinds of threats known in advance — radiating, biological etc.
The more reinforced is a bunker, the smaller number of bunkers can prepare mankind in advance, and it will be more difficult to hide such bunker. If after a certain catastrophe there was a limited number of the bunkers which site is known, the secondary nuclear war can terminate mankind through countable number of strikes in known places.
The larger is the bunker, the less amount of such bunkers is possible to construct. However any bunker is vulnerable to accidental destruction or contamination. Therefore the limited number of bunkers with certain probability of contamination unequivocally defines the maximum survival time of mankind. If bunkers are connected among themselves by trade and other material distribution, contamination between them is more probable. If bunkers are not connected, they will degrade faster. The more powerfully and more expensively is the bunker, the more difficult is to create it imperceptibly for the probable opponent and so it easeir becomes the goal for an attack. The more cheaply the bunker, the less it is durable.
Casual shelters — the people who have escaped in the underground, mines, submarines — are possible. They will suffer from absence of the central power and struggle for resources. The people, in case of exhaustion of resources in one bunker, can undertake the armed attempts to break in other next bunker. Also the people who have escaped casually (or under the threat of the comong catastrophe), can attack those who was locked in the bunker.
Bunkers will suffer from necessity of an exchange of heat, energy, water and air with an external world. The more independent is the bunker, the less time it can exist in full isolation. Bunkers being in the Earth will deeply suffer from an overheating. Any nuclear reactors and other complex machines will demand external cooling. Cooling by external water will unmask them, and it is impossible to have energy sources lost-free in the form of heat, while on depth of earth there are always high temperatures. Temperature growth, in process of deepening in the Earth, limits depth of possible bunkers. (The geothermal gradient on the average makes 30 degrees C/kilometers. It means, that bunkers on depth more than 1 kilometre are impossible — or demand huge cooling installations on a surface, as gold mines in the republic of South Africa. There can be deeper bunkers in ices of Antarctica.)
The more durable, more universal and more effective, should be a bunker, the earlier it is necessary to start to build it. But in this case it is difficult to foresee the future risks. For example, in 1930th years in Russia was constructed many anti-gase bombproof shelters which have appeared useless and vulnerable to bombardments by heavy demolition bombs.
Efficiency of the bunker which can create the civilisation, corresponds to a technological level of development of this civilisation. But it means that it possesses and corresponding means of destruction. So, especially powerful bunker is necessary. The more independently and more absolutely is the bunker (for example, equipped with AI, nanorobots and biotechnologies), the easier it can do without, eventually, people, having given rise to purely computer civilisation.
People from different bunkers will compete for that who first leaves on a surface and who, accordingly, will own it — therefore will develop the temptation for them to go out to still infected sites of the Earth.
There are possible automatic robotic bunkers: in them the frozen human embryos are stored in a certain artificial uterus and through hundreds or thousand years start to be grown up. (Technology of cryonics of embryos already exists, and works on an artificial uterus are forbidden for bioethics reasons, but basically such device is possible.) With embryos it is possible to send such installations in travel to other planets. However, if such bunkers are possible, the Earth hardly remains empty — most likely it will be populated with robots. Besides, if the human cub who has been brought up by wolves, considers itself as a wolf as whom human who has been brought up by robots will consider itself?
So, the idea about a survival in bunkers contains many reefs which reduce its utility and probability of success. It is necessary to build long-term bunkers for many years, but they can become outdated for this time as the situation will change and it is not known to what to prepare. Probably, that there is a number of powerful bunkers which have been constructed in days of cold war. A limit of modern technical possibilities the bunker of an order of a 30-year-old autonomy, however it would take long time for building — decade, and it will demand billions dollars of investments.
Independently there are information bunkers, which are intended to inform to the possible escaped descendants about our knowledge, technologies and achievements. For example, in Norway, on Spitsbergen have been created a stock of samples of seeds and grain with these purposes (Doomsday Vault). Variants with preservation of a genetic variety of people by means of the frozen sperm are possible. Digital carriers steady against long storage, for example, compact discs on which the text which can be read through a magnifier is etched are discussed and implemented by Long Now Foundation. This knowledge can be crucial for not repeating our errors.

SpaceX Falcon 1 Rocket Reaches Orbit on 4th Try

Posted by in categories: habitats, lifeboat, space

This is cross-posted from my blog. This milestone by SpaceX is directly relevant to programs by Lifeboat such as the AsteroidShield and SpaceHabitat, and possibly also (eventually) to Space-Based Solar Power.

$153 million/city thin film plastic domes can protect against nuclear weapons and bad weather

I had previously looked at making two large concrete or nanomaterial monolithic or geodesic domes over cities which could protect a city from nuclear bombs.

Now Alexander Bolonkin has come up with a cheaper, technological easy and more practical approach with thin film inflatable domes. It not only would provide protection form nuclear devices it could be used to place high communication devices, windmill power and a lot of other money generating uses. The film mass covered of 1 km**2 of ground area is M1 = 2×10**6 mc = 600 tons/km**2 and film cost is $60,000/km**2.
The area of big city diameter 20 km is 314 km**2. Area of semi-spherical dome is 628 km2. The cost of Dome cover is 62.8 millions $US. We can take less the overpressure (p = 0.001atm) and decrease the cover cost in 5 – 7 times. The total cost of installation is about 30–90 million $US. Not only is it only about $153 million to protect a city it is cheaper than a geosynchronous satellite for high speed communications. Alexander Bolonkin’s website

Disruptions from small recessions to extinctions

Cross posted from Next big future by Brian Wang, Lifeboat foundation director of Research

I am presenting disruption events for humans and also for biospheres and planets and where I can correlating them with historical frequency and scale.

There has been previous work on categorizing and classifying extinction events. There is Bostroms paper and there is also the work by Jamais Cascio and Michael Anissimov on classification and identifying risks (presented below).

A recent article discusses the inevtiable “end of societies” (it refers to civilizations but it seems to be referring more to things like the end of the roman empire, which still ends up later with Italy, Austria Hungary etc… emerging)

Sir Edmund Hillary, First to Summit Everest Has Died at 88

Posted by in category: habitats

The BBC reports that Sir Edmund Hillary, the New Zealand native who, along with Sherpa Tenzing Norgay of Nepal was the first man to successfully summit Mount Everest, had died at 88 years of age. Hillary was apparently injured this past April when he fell while visiting Nepal and the reports state that this injury contributed to a decline in his health that ultimately culminated in his passing.

While his fame was first and foremost as a result of his triumphant effort on Everest in 1953, he was revered in Nepal for his efforts to help the Nepalese Sherpas improve their access to medicine, education and other modern conveniences and his legacy will continue in the form of those edifices in Nepal that exist as a result of his work.

Sir Ed, as he preferred to be called, was also something of an environmentalist. Upon a recent visit to the base of Everest he was so dismayed by the condition of the mountain (as a result of the decades of equipment including things such as spent oxygen bottles and massive amounts of inorganic and thus non-biodegradable gear) that he called for a fifty year moratorium on permits being issued to attempt ascents on the peak. He called upon the climbing community to make an effort to repair the damage to the fabled crag by packing out the detritus that was scarring his beloved mountain.

While the passing of this great man has relatively little to do with the mission of the Lifeboat Foundation, it seemed appropriate to report on his passing simply because he demonstrated that with sufficient will even things that are seemingly impossible are well within the grasp of those for whom failure is not an option.

Aerospaceplanes and space solar power

Posted by in categories: habitats, space

Supplying a substantial percentage of America’s future electrical power supply from space using SBSP (space-based solar power) systems can only be expressed as a giant leap forward in space operations. Each of the hundreds of solar power satellites needed would require 10,000–20,000 tons of components transported to orbit, assembled in orbit, and then moved to geostationary orbit for operations. The scale of logistics operations required is substantially greater than what we have previously undertaken. Periodically, industrial operations experience revolutions in technology and operations. Deep sea oil exploration is an example. Within a couple decades, entirely new industrial operations can start and grow to significant levels of production. The same will happen with space industrialization when—not if—the right product or service is undertaken. SBSP may be the breakthrough product for leading the industrialization of space. This was our assumption in conducting the study. As the cost of oil approaches $100 a barrel, combined with the possibility of the world reaching peak oil production in the near future, this may turn out to be a valid assumption.

Inflatable Habitats for Polar and Space Colonists

Posted by in category: habitats

From Physorg.com:

Humanity has long since established a foothold in the Artic and Antarctic, but extensive colonization of these regions may soon become economically viable. If we can learn to build self-sufficient habitats in these extreme environments, similar technology could be used to live on the Moon or Mars.

The average temperature of the Antarctic coast in winter is about −20 °C. As if this weren’t enough, the region suffers from heavy snowfall, strong winds, and six-month nights. How can humanity possibly survive in such a hostile environment?
