Lifeboat Foundation

For any assembly or structure, whether an isolated bunker or a self sustaining space colony, to be able to function perpetually, the ability to manufacture any of the parts necessary to maintain, or expand, the structure is an obvious necessity. Conventional metal working techniques, consisting of forming, cutting, casting or welding present extreme difficulties in size and complexity that would be difficult to integrate into a self sustaining structure.

Forming requires heavy high powered machinery to press metals into their final desired shapes. Cutting procedures, such as milling and lathing, also require large, heavy, complex machinery, but also waste tremendous amounts of material as large bulk shapes are cut away emerging the final part. Casting metal parts requires a complex mold construction and preparation procedures, not only does a negative mold of the final part need to be constructed, but the mold needs to be prepared, usually by coating in ceramic slurries, before the molten metal is applied. Unless thousands of parts are required, the molds are a waste of energy, resources, and effort. Joining is a flexible process, and usually achieved by welding or brazing and works by melting metal between two fixed parts in order to join them — but the fixed parts present the same manufacturing problems.

Ideally then, in any self sustaining structure, metal parts should be constructed only in the final desired shape but without the need of a mold and very limited need for cutting or joining. In a salient progressive step toward this necessary goal, NASA demonstrates the innovative Electron Beam Free Forming Fabrication (http://www.aeronautics.nasa.gov/electron_beam.htm) Process. A rapid metal fabrication process essentially it “prints” a complex three dimensional object by feeding a molten wire through a computer controlled gun, building the part, layer by layer, and adding metal only where you desire it. It requires no molds and little or no tooling, and material properties are similar to other forming techniques. The complexity of the part is limited only by the imagination of the programmer and the dexterity of the wire feed and heating device.

Many years ago, in December 1993 to be approximate, I noticed a space-related poster on the wall of Eric Klien’s office in the headquarters of the Atlantis Project. We chatted for a bit about the possibilities for colonies in space. Later, Eric mentioned that this conversation was one of the formative moments in his conception of the Lifeboat Foundation.

Another friend, filmmaker Meg McLain has noticed that orbital hotels and space cruise liners are all vapor ware. Indeed, we’ve had few better depictions of realistic “how it would feel” space resorts since 1968’s Kubrick classic “2001: A Space Odyssey.” Remember the Pan Am flight to orbit, the huge hotel and mall complex, and the transfer to a lunar shuttle? To this day I know people who bought reservation certificates for whenever Pan Am would begin to fly to the Moon.

In 2004, after the X Prize victory, Richard Branson announced that Virgin Galactic would be flying tourists by 2007. So far, none.

A little later, Bigelow announced a fifty million dollar prize if only tourists could be launched to orbit by January 2010. I expect the prize money won’t be claimed in time.

“We might be entering an Age of Pandemics… a broad array of dangerous emerging 21st-century diseases, man-made or natural, brand-new or old, newly resistant to our current vaccines and antiviral drugs…. Martin Rees bet $1,000 that bioterror or bioerror would unleash a catastrophic event claiming one million lives in the next two decades…. Why? Less forest, more contact with animals… more meat eating (Africans last year consumed nearly 700 million wild animals… numbers of chickens raised for food in China have increased 1,000-fold over the past few decades)… farmers cut down jungle, creating deforested areas that once served as barriers to the zoonotic viruses…” — Larry Brilliant, Wall Street Journal

Jacob Haqq-Misra and Seth D. Baum (2009). The Sustainability Solution to the Fermi Paradox. Journal of the British Interplanetary Society 62: 47–51.

Background: The Fermi Paradox
According to a simple but powerful inference introduced by physicist Enrico Fermi in 1950, we should expect to observe numerous extraterrestrial civilizations throughout our galaxy. Given the old age of our galaxy, Fermi postulated that if the evolution of life and subsequent development of intelligence is common, then extraterrestrial intelligence (ETI) could have colonized the Milky Way several times over by now. Thus, the paradox is: if ETI should be so widespread, where are they? Many solutions have been proposed to account for our absence of ETI observation. Perhaps the occurrence of life or intelligence is rare in the galaxy. Perhaps ETI inevitably destroy themselves soon after developing advanced technology. Perhaps ETI are keeping Earth as a zoo!

The ‘Sustainability Solution’
The Haqq-Misra & Baum paper presents a definitive statement on a plausible but often overlooked solution to the Fermi paradox, which the authors name the “Sustainability Solution”. The Sustainability Solution states: the absence of ETI observation can be explained by the possibility that exponential or other faster-growth is not a sustainable development pattern for intelligent civilizations. Exponential growth is implicit in Fermi’s claim that ETI could quickly expand through the galaxy, an assumption based on observations of human expansion on Earth. However, as we are now learning all too well, our exponential expansion frequently proves unsustainable as we reach the limits of available resources. Likewise, because all civilizations throughout the universe may have limited resources, it is possible that all civilizations face similar issues of sustainability. In other words, unsustainably growing civilizations may inevitably collapse. This possibility is the essence of the Sustainability Solution.

Implications for the Search for Extraterrestrial Intelligence (SETI)
If the Sustainability Solution is true, then we may never observe a galactic-scale ETI civilization, for such an empire would have grown and collapsed too quickly for us to notice. SETI efforts should therefore focus on ETI that grow within the limits of their carrying capacity and thereby avoid collapse. These slower-growth ETI may possess the technological capacity for both radio broadcasts and remote interstellar exploration. Thus, SETI may be more successful if it is expanded to include a search of our Solar System for small, unmanned ETI satellites.

Implications for Human Civilization Management
Does the Sustainability Solution mean that humanity must live sustainably in order to avoid collapse? Not necessarily. Humanity could collapse even if it lives sustainably—for example, if it collides with a large asteroid. Alternatively, humanity may be able to grow rapidly for much longer—for example, until we have colonized the entire Solar System. Finally, the Sustainability Solution is only one of several possible solutions to the Fermi paradox, so it is not necessarily the case that all civilizations must grow sustainably or else face collapse. However, the possibility of the Sustainability Solution makes it more likely that humanity must live more sustainably if it is to avoid collapse.

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.

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?
