Titanic Resources

Posted by Jacques Chester on Thursday, February 14, 2008

More about industrialising the solar system, this time based on work from the European Space Agency. The ESA have estimated that the oceans and dunes of hydrocarbons on Titan vastly outstrip Earth’s puny supply of fossil fuels.

Don’t misunderstand me, I’m not proposing that we mine it on Titan and burn it here. Instead I am pointing out that a cheap, plentiful source of hydrocarbons has been an important requirement for the colonisation and industrialisation of our own solar system. We can get minerals easily enough from the moon, but life depends on and is composed of hydrocarbons. The mapping of Titan shows where we can find an astonishingly large supply of feedstock for biomass.

    Jc: Given your political leaning I’m surprised you report this.

    How about “The mapping of Titan”, paid for out of the great (and forced) generosity of the American tax payer who give huge subsidizies to one of the great pinnacles of American (and indeed world) achievements, NASA — an organization doing research that often has no relevance to anyone likely to benefit directly from it within their lifetime, excluding out of intellectual curiosity.

    conrad;

    In this case I have made the distinction between the virtue of the science, which is undeniable, and the virtue of it being publicly funded, which is debatable, but which I’m not debating here.

    In any case, somebody will have to mine Titan to get those hydrocarbons to where they’re wanted, and I’ll take bets that it will be done for profit.

  3. conrad said:

    Sorry Jc, I was just teasing, but I certainly agree with you on the second (if we ever get there, that is!).

    Nah, it’s OK. I got a similar bit of stick when I praised the 50th anniversary of Sputnik — from my own side of the political fence. :)

    n artist’s imagination of Saturn’s largest moon Titan

    Titan’s surface organics surpass oil reserves on Earth

    13 February 2008
    Saturn’s orange moon Titan has hundreds of times more liquid hydrocarbons than all the known oil and natural gas reserves on Earth, according to new Cassini data

    Wtf. I have been lead to believe that our hydrocarbons like oil comes from dead dinosuars and organic matter and that ambiotic theory was crap. It isn’t?

  6. NPOV said:

    There almost certainly is abiotic oil on Earth too, just not that we can extract economically with current technology.

    How about something a bit closer to home - the abundance of He3 on the moon. The article notes that, due to the amount of energy it produces, its worth something like $3billion a ton, and there may be as much as one million tons on the moon.

    All we need to do is set up a convict colony there and build a could of great big rail guns to toss the mined He3 down into Earth’s gravity well. Should be fine, as long as they don’t plan a rebellion with the aide of a self-aware computer…

  8. Jacques Chester said:

    dr faustus — it presumes that fusion is a going concern. And if you’ve got an industrial base on the moon, that harsh mistress, you’re most of the way to orbital solar power anyway.

    JC, the hydrocarbons on Titan are very simple (mostly methane and ethane) relative to the hydrocarbons on earth due to them being formed from simple chemical reactions, whereas the vast majority of earth’s hydrocarbons (excluding natural gas) are complex because they come from the breakdown of even more complex living organisms (mostly plants).

    That hydrocarbons can be generated from natural sources has been known for a long time and does not to support the pseudoscientific abiotic oilers.

    I wonder what solar energy fans would think of the ultimate commitment to making the most of our sun … the Dyson Sphere, which requires dismantling entire planets.

    Probably in order to terraform Mars as a commercial colonial enterprise.

  14. Jacques Chester said:

    tigtog;

    Mars will probably never be terraformed. Much cheaper to mass produce o’neill style colonies. Much more practical too: terraforming could take decades or centuries, would cost a bomb, only double available living space and doom people who are raised on Mars to stay there. Oh, and it’s at the bottom of a gravity well and is not very accessible from Earth compared to the moon or the asteroid belt.

  15. gilmae said:

    We go to Titan to construct a fantastically complex industrial site to extract hydrocarbons in order to ship them back to Mars or the Moon or artificial platforms - I suggest the Moon personally, it’d be cheaper - so we can use them as feedstock for biomass.

    Hmm.

    Don’t get me wrong, I love the idea, but it seems horrendously complicated and expensive. It might even turn out cheaper to work out a way to do it locally. Especially since I suspect whatever craft we have capable of hooning around the solar system will be quite busy indeed finding water for the people doing the colonisation/industrialisation.

    The again, Randall Munroe wants to solve our propulsion issues with lasers.

  17. Jacques Chester said:

    gilmae;

    Titan is one such source but is not the only one. But it’s the biggest so far the we could get at relatively easily.

    As for water, that’s part of the point. Once you orbital colonies and orbital solar it becomes industrially trivial to extract oxygen from moonrock and regolith. But the moon has just about zero carbon, hydrogen or nitrogen. That’s why you need to look further afield. When you have methane and oxygen, you can create water in situ (amongst other things).

    What is most likely is that asteroids will be mined for hydrocarbons first, with Titan perhaps coming later.

    Compared to lifting water or oil out of Earth’s gravity well, crossing the solar system is actually cheaper in dollars and energy.

    True. Mars will probably be exploited for what can be dug up from the regolith and rocks though. It might be more long-term efficient (on a centuries scale) to use terraforming with hydrocarbon mass addition to at least build up the atmosphere sufficiently that people working there only need pressure suits instead of full spacesuits.

  19. Patrick said:

    I was fine with exploited. With any luck it’d be by me.

  20. Jacques Chester said:

    tigtog;

    It could go either way — it’ll come down to cost and ownership. I don’t think Mars will go past being a tourist destination. Anything worth mining is easier to get from the asteroid belt.

    Still, it could be done, and Titan’s methane would make it a lot more doable.
