Now, as I said, I don't think there is any reason to do such a crash program
on a war-footing, and any such money would be better invested for
sustainability on Earth first. But, building on this theme, for fun, let's
just calculate the rough cost to evacuate the Earth so all the resource
doomsters are "left behind" if they want. :-)
http://en.wikipedia.org/wiki/Left_Behind
Current launch costs are about US$10,000 a pound. People on starvation diets
might weigh about 100 pounds. So, that's about US$1 million per person for
launch costs using today's technology in small production runs. I feel it
reasonable to assume that if we were going to launch billions of people into
space, launch costs would come down by at least a factor of ten to US$100K
per person, considering how people are already talking about such lower
costs, and the actual energy to lift someone into space if you can do it
really efficiently (space elevator) is maybe US$200 worth of electricity:
http://lists.canonical.org/pipermail/kragen-tol/2005-October/000802.html
We could burn coal to make the fuel for the rockets. :-) A Saturn V could
lift 262,000 lb to low earth orbit, or about 1000 emaciated people also with
162 lbs of protective padding for chairs, etc. The mass of a Saturn V fueled
is about 7 million pounds, so that is 7000 lbs per person (mostly fuel), or
about the weight of a big SUV per person. The metal weight is about 500,000
pounds,
http://www.globalsecurity.org/space/systems/saturn-v.htm
or about 500 lbs per person, or the weight of a very tiny car. So, that is
easily feasible for our infrastructure to churn out per person for everyone
in the world, considering there are close to a billion cars in the world
today. Since we're evacuating the planet, we could melt down all the
construction equipment and so on, so we might not even need to do much extra
mining. And that is with 1960s technology, presumably rockets today with
things like carbon fiber composites could be much lighter and more resource
efficient than the 1960s Saturn V that got humans to the Moon.
So, seven billion people soon, minus a few doomsters, times US$100K per
person, is US$700 trillion. The world GDP is about US$60 trillion, so, in
round numbers, this is about ten years of world economic output to put
everyone into space.
We can assume that with these self-replicating space habitat seeds that an
entire space infrastructure is being prepared for free from sunlight and
lunar ore and asteroidal ore (though it might take some time to produce it
on an exponential growth curve). So, we only need to get people into low
Earth orbit and shuttles can ferry people without luggage beyond low Earth
orbit to a life of abundance produced with resources from space.
Also, since we're evacuating the entire planet to leave it as a nature park,
we don't need to do any upkeep on infrastructure as it is all abandoned. So,
we can devote close to 100% of the industrial base to producing rockets.
Also, people in space can still provide services to Earth like telemedicine
or teleoperating mining equipment and launch control, so essential services
can be kept going the whole time even as the last person goes on the last
rocket (except the doomsters who want to stay :-).
The Earth's ozone layer might be greatly damaged by all that rocket exhaust,
but let's assume seven billion space faring humans can fix that from space
somehow, like with tuned lasers. :-) And if they can't, well, they don't
live on Earth anymore anyway, and the extra radiation may increase the speed
at which the planet generates new species to make up for the current mass
extinction humans are causing. :-(
So, within ten years of the success of these space habitat seeds we could
get all but the doomsters off planet. :-) So, ten years more after a
previous twenty years of dedicated efforts to build the first seeds and a
first self-replicating habitat that can produce more seeds (plus an
extensive defacement of the Moon for materials close to Earth: :-)
http://en.wikipedia.org/wiki/Mass_driver.
Or, ten years of evacuation, plus (guessing) twenty years of prep time, and
that's thirty years altogether.
So, I'm suggesting, within thirty years, humans, as a species, with today's
technology (actually, just 1970s technology), could evacuate the planet
entirely -- except for the doomster "meek" -- who shall inherit the Earth
and then can fight it out over their unimaginative view of depleted
resources while the rest of humanity lives in abundance. :-) As Gerry
O'Neill asked his students, what is the right place for a technologically
advanced society? And the answer he got, based on access to energy and raw
materials and no pollution worries, was space, not Earth.
That does not mean you can't have a technologically advanced civilization on
the planet Earth, of course, as long as you live within local energy budgets
(which are thousands of times what we use from the Sun). You would also need
to recycle close to 100% to avoid polluting the biosphere. And on Earth, you
should not grow too much beyond continually expanding better design to do
more with less or to make new types of dirt into useful resources without
hurting the biosphere much in the process. But even by those standards, and
considering the ocean is mostly empty of humans, we could probably support
one hundred billion people on the Earth in cities, easily, using sustainable
urban technology (assuming not many of them wanted to do real camping as
recreation, which would tax the rest of the biosphere). With ocean
seasteads, most of those one hundred billion people might even have
ocean-front condos. :-)
Note that naysayers at this page suggest there being no point to evacuating
the Earth to space as there is nowhere to go; but they don't understand that
you could "live of the land" in space if you prepare it first with an
automated infrastructure:
"Why might we have to evacuate earth?"

Now, would I suggest we do this? No. Would there be obstacles and so on?
Yes. Would most of humanity go along with this? Probably not, as many people
have an attachment to the land of their birth. Would lots of people die of
heart attacks on the way up? Probably. Would plenty of stuff go wrong and
hundreds of millions of people die (10%? 20%? 90%? 99%?) if this sort of
thing got rushed, like entire habitats and space ships blowing up for stupid
reasons, or there being unforeseen cancer hazards, or there being malicious
computer viruses destroying life support systems, and so on? Almost certainly.
Would the money be better spent fixing up the Earth first, just from an
ethical perspective? Surely -- maybe the last thing we want is a solar
system filled up with the same kind of people who could not make a good
thing work out on Earth when they had it easily within their technical
grasp. As I say, the best reason to go into space is because we are happy
down on Earth and think it might be fun to have cities in space too. And as
above, I am guessing we could support more than ten times our current
population in urbanized seasteads.
My point is not that we *should* do any of this evacuation into space, but
that we *could*. It is to suggest that, with a little imagination based on
existing research studies done by NASA (and then buried), the numbers
actually work out (with some handwaving. :-) So, a total evacuation of the
Earth for space could be plausibly done within the lifetime of probably
anybody on this list (even though you might have to go on a starvation diet
for many months, and you'd need to leave everything behind except your
underwear to cut launch costs. :-)
So, the implication, if such a thing is within our plausible grasp, is that
there is cause for hope. It is to suggest that everything people are going
on about in current politics, how we need to spend all that money for our
"protection", or how we are running out of oil or iron or whatever (anything
except helium that nobody talks about), it's all just all scaremongering
from a technical perspective (even if the social issues of inequity or
change are real, and I'm all for addressing them).
So, with that as a background possibility, that within thirty years almost
every middle-aged or younger human being alive today could be living in
space in relative luxury, I just don't see the point for the gloom and doom
about running out of oil, global climate change, etc..
Again, global climate change and Peak Oil may be serious problems, ones that
may cause immense amounts of human suffering, but they are only serious
*social* problems. There are easily approachable politically (tax fossil
fuels and redistribute the taxes as a basic income), technically (deploy PV
& other renewables), and/or space-related (as above) solutions.
People are all too willing to say, "we have billions of people trashing the
planet", while not accepting that "we have billions of people who could fix
the planet or come up with other creative ideas too" (and already have, as
I've gotten these sorts of ideas from many who went before me).
So, call me a technical optimist, but a social pessimist. :-) Which may make
me a nice complement to the social optimists but technical pessimists one
often reads, like the ones writing the 20 theses that started this thread. :-)
Now, if we can find someone who is a social optimist and a technical
optimist, we'll be set, as they may actually accomplish something. :-)
"Think globally, act locally, plan modestly. (René Dubois)"
Obviously, the suggestions above fail on the "modest" part. :-)
