    Airliners are private.
    Health care seems private from this end - most people I know takes at least one type of medicine he buys himself (homeopathic or prescribed non-free medicine).
    We have medical plans, payed by docking our salary. If I need a major surgery, I pay some of it and my financed-out-of-my-salary insurance pays the rest. Nothing here is government, nor profit-free.
    Same for accidents insurance, in my history. I was the cause of the accident so I had to pay, despite insurance. No government protected me.

    Ah, rich people, is there anything they can't do?

    Enough rich people are willing to pay 200.000$ to get to space that a huge company decides it's worthwhile to spend millions building ships that'll fly to space.

    When that's done, they'll realise enough people are willing to pay for actually staying a while in space, and enough can be profited by research in space, that they'll build private space stations.

    Yes, but you only have one chance to grab the spinner. If the cargo fails, it has to turn around (somewhere else, I assume. days if not weeks, then).

    I'm not sure I totally understand how this works. I understand the cargo shifts the orbit of the spinner, and has to put him back in place when he finishes, no? (or rather, the spinner's mass has thrusters)

    I was thinking of cargo drops. Won't it be very cost effective to chop large blocks of moon rock and toss them to Earth? (re-usable ceramic container and parachutes, probably. Ocean landing, obviously)
    This assumes we have any need for these chemicals. While moonrocks have lots of useful materials, I think they're much cheaper dug out of the ground, no?

    Processing will probably be more cost effective on the moon but pricey to start with (isn't a small mining facility cheaper than the facility needed to refine the output?)

    I've gone completely off topic here and kind of corenered myself...

    This could be a good idea for Mars travel, since you'd want to be travelling very fast, and expending alot of energy.

    I think the moon is too close for something like this to be profitable. You'd gain the kinetic energy of the ship moving from earth to the moon or back, but there's not much of it.

    How does a ship rendevous with such a thing? Isn't is supposed to be a tense cable, spinning faster than it's orbit 'should' be?
    An incoming ship is supposed to 'catch on', exchanging energy with the spinner?

  8. Re:Long term environmental impact. on Liquid Oxygen from Lunar Rocks · · Score: 4, Informative

    The moon has no outer shell (well, it does, but the difference is only in density and compound).
    It's not harder to dig as you go (on Earth you have more problems with heat and earthquakes the lower you go), and the composition is pretty much the same all around (no iron core).

    Summary:
    You will never 'run out of moon'
    Even if you eat up 25% of it, you could still just as easily continue mining the rest. You'll probably only ruin the ecology of Earth (by the time you mine a large mass of the moon, you'd have built space cities bigger than the current Earth population).

    "The moon's mass is approximately 7.35e22 kg with a density about 3/5 that of Earth"
    It's not 40% iron like Earth.
    Let's say it's 0.1% metal (usable, refined, post-processed metal)
    that's 7.35e19 kg of metal.

    The Empire state building weighs 365,000 tons
    That's 3.65e8 kg (yeah, I know it's not metal)
    So, the moon will provide: (perl, make it so:)
    201,369,863,013.699 empire state buildings.

  9. Re:Only "potentially" oxygen? on Liquid Oxygen from Lunar Rocks · · Score: 1

    IANAC:
    If you take out the oxygen from the metal oxide, it will form into O2 (liquid, in this case, because we're on the moon). Heat it up and it becomes pure (lethal) oxygen.

    You'll need quite a bit of H2 to mix it with.
    If H2 will be present, some water will form on it's own (no?). Anyway, O2 and H2 will form H20 and give you some energy while they're at it (Fuel cell).

    There's less Hydrogen than Oxygen on the moon, so you might need to bring excess H2.

    Question:
    Can't fusion be used for this? If you heat up any mass enough, it'll break up and form as hydrogen, and all kinds of basic atoms, no?
    It seems unreasonable to detonate a hydrogen bomb to get carbon, but the moon has gone through much worse, no?

  10. Re:Cargo only on Liquid Oxygen from Lunar Rocks · · Score: 1

    The cost from the moon to earth orbit and back (from earth orbit to the moon) is small. In orders of magnitude smaller than the price to leave Earth's well.
    I can't see how you store that energy in spinners, or how spinner energy can launch anything off Earth.

    To launch out of earth with a sky hook requires technology we don't yet possess (cables built of nanotubes or other super-strong material)

    There, was that confusing enough? I rewrote it twice.

    This brings to mind an interesting idea:

    Israel has a parliament system - in the national elections each citizen votes for a party, and the 120 seats in parliament are divided by votes.

    Technically, every parliament member can vote as he likes on any vote

    The government is composed of the 'top' of the coalition parties, and, well, their relatives.

    The members who join the coalition spend more time in government work (comittees and such)
    The members who are actually ministers spend even more time on such things, not to mention spending half the time abroad

    Read the equations. They're all wrong.
    It comes to:
    fi*fp*n
    /
    fi*fp*n+1
    but, fi is the chance that a posthuman civilisation will simulate all of your life's history, and n is its computing power. but it is unlikely that it will simulate fi*n times anything. n should be the chance that they can, which would approximate 1
    so the formula is:
    fi*fp
    /
    fi*fp+1
    but here both fi and fp are between 0 and 1, and this does not nessecarily equals 1 (that is, you are not nessecarily very likely to be a simulation. It depends on how likely you are to be simulated)
    So, if you think you're simulated, you'd be interesting to simulate, and therefor you are.

  23. Spiking neurons (or their models, anyway) on Computer Made From DNA And Enzymes · · Score: 1

    The latest models of neuron behavior allow the room for 'paralel computing':
    The neuron sends information in the exact location-in-time of the firing, as compared to other firings and firings from other neurons
    So, a firing is not a "1" bit, but more like a number, signifying when it was shot.
    I think the shape and size of the shot matter too, but I'm talking temporal here. I'm getting somewhere, trust me
    If a neuron fires 100 times a second, you can think of it as an 'analog array' lengthing a second, and filled with up to 100 'spots' or 'points' - the actual firings

    Neurons make computation from the firings of connected neurons, and from the firings' temporal proximity.
    For instance, there exists a layer on the vision cortex (in cats, I believe. But prolly humans too) in which each neuron is connected to a 'line' (many neurons forming a line on the cortex itself), and fires up as firings proceed in a certain order, in a certain time.
    Therefor, the neuron only fires when there is movement in a certain direction (and will strongly abstain from firing if the movement is the other way)

    So, basically, my point is 'yeah'.
    A neuron firing sends many different signals to many different neurons, because each of them sees the signal differently, having gotten different firings from other neurons they connect to.
    So when you think of a neuron's connections to other neurons (the synapses, lag on synapse, etc.) you can think of them as asking "what is the meaning of this neuron's firing, in time? Does it reinforce what is happening right now, or supresses?". If the neuron's firing has no relevancy in time, the connection is not really made (its weight is 0 - no connection).
