    Honestly, who in their right mind wants to live _on_ a planet?

    The environment is totally unpredictable and you are utterly at the mercy of forces vastly beyond your control. You have to share a single fickle and tiresomely fragile environment with everyone and everything there, including heavy industry. And the parameters of that single environment (air pressure and content, temperature, etc) can be modified locally only with great effort; some things like gravity are basically out of the question entirely. Compounding all this is the fact that you are living at the bottom of a fairly steep gravity well, which makes getting anywhere else a difficult proposition at best. The geometry of the place is largely 2-dimensional and is encumbered with all the inefficiencies thereof.

    Nuts to that. Give me a habitat in space any day.

    > If by "not too far" you mean "we've started to bang the rocks together" ...

    Not at all. Getting to space at all is by far the hardest part of any interstellar journey. For instance, it takes as much delta-v to get to orbit as it takes to get form earth orbit to Mars. And unlike the Martian Express, it all has to be applied pretty quickly. It's _insanely_ difficult.

    Actually getting from one star to another is nowhere near as hard to research as this first step. We have any number of propulsion systems with the fuel efficiency to get up to speed, and we _have_ demonstrated the ability to create artificial ecologies that are sustainable in the long-term. Certainly there are still problems to be overcome (high LEO launch costs chief among them), but we're not exactly at the stone age of development along these lines.

    Imagine the worst-case scenario. The army has taken on the role of occupying its own country. Martial law, tanks in the streets, firing squads for anyone who complains, the works. Those tanks and planes are powerful, yes. But they don't run themselves. All those guys in uniform go home eventually. That's a big stretch of time in which they are not armed and armored, sitting safely behind security checkpoints. In Iraq and Vietnam we were foreign occupiers. Our soldiers were in a secure base or they were combat-ready. The supply line only terminated in a war zone. And still the costs were too high to bear for long. Imagine if the entire supply line, from start to finish, was inside 'enemy territory'. Imagine if troops (and even their families) were constantly coming under fire, even on their supposed R&R. The weapons factories, the trucking system, the entire M/I complex is hideously vulnerable if it has to operate while surrounded by armed foes.

    Same thing goes for run-of-the-mill cops and judges, bureaucrats and politicians. It's easy to get away with being a cruel public official if the population has no choice but to take it. It's quite another if many of them are armed, and you risk getting capped by some victims's spouse or parent or loved one every time you step outside.

    Personally, I find the idea of a domestic insurgency carrying out campaigns of planned assassination or of diligently working to disrupt national transportation and communications systems to be distasteful in the extreme. That volunteering to serve one's country would open one's family up to risk of grave violence is beyond repugnant. The number of people killed annually in crimes or accidents involving firearms is truly appalling. But if the 20th century has shown us anything, it's that those casualties are _nothing_ compared to those that can be inflicted by a government that becomes the enemy of its own people.

    > Spacecraft hulls are made of aluminum, titanium, and composite materials. There is very little iron.

    That's because spacecraft hulls currently have to be hauled out of a steep gravity well, and mass costs money. So they use flimsy, lightweight materials. If the stuff is already up there and need only be refined, then you could use whatever you wanted. For structural components, I'd take steel over aluminum any day of the week, thank you very much.

    Jury selection should be strictly random. No cherry picking should be allowed.

    Well, we really do want to have it both ways. We want to have a system that can let attorneys strke out truly horrendous jurors but is still largely beyond their control.

    I'd argue that the current voi dire system is fine, it is simply excessive and thus works in the wrong direction. It lets attorneys choose who will be on the jury rather than who won't. And this is simply because each side can strike too many potential jurors.

    How about, each side can arbitrarily strike one and only one juror, and they may each make a formal appeal to the judge citing reasons why they would like a second juror removed from consideration. This would keep the random factor in place but still let the attorneys remove, for instance, the Klan member from a trial involving minorities.

    The grandparent here was right. I have never been called for jury duty, and I'd absolutely love to serve. But it saddens me to think that I'd be told to go home due to being intelligent, university educated, and a CS professional.

H2 as a power system is like electrical batteries; it's a common medium that can be generated from any number of sources of varying cleanliness and efficiency.

    Now, it just so happens that the cheapest and most efficient means of making H2 _today_ involves fossil fuels. But that will change in the future, as oil and natural gas get more expensive and electrolysis and biological derivations get cheaper.

    No, space travel is fairly easy. You apply thrust in one direction, your ship heads off in the opposite direction. Building spaceships is easy, really far easier than submarines, since containing internal pressure is much easier than withstanding external. Orbital dynamics are very well worked out, so navigation is no problem. Raw materials are no problem, there's a universe of stuff out there just waiting to be used.

    The part that is difficult is getting out to space in the first place. It takes as much delta-v to get to orbit as it does getting from Earth to Mars, and it all has to be applied in the space of a few minutes. That's why all our space-going efforts have been flimsy, rickety, barely functioning laughingstocks. It costs it weight in gold to ship something to LEO on the Shuttle, and stands a fair chance of never making it at all.

    I'm all for private industry in space, and in fact it's the only way anything worthwhile will happen there. Depending on a command economy to start mining asteroids and harvesting comets and setting up habitats and factories is a joke. But the entry costs to the space industry are so high that it precludes all but the wealthiest and most risk-loving non-national entities from taking part. That's why NASA is such a joke; rather than try to open up space for the rest of us, they got it just far enough that they can get there and left it with that. The probes, the station, even the Apollo missions, they were all Very Cool ventures, but in the end they didn't help the rost of us do anything. All NASA needed to do, all they've ever needed to do, was bring LEO launch costs down to the point where all the entrepreneurs stuck at the bottom of this gravity well can get a chance at space. Instead, they've actually regressed. The Shuttle is less capable, more expensive, and has lower payload capacity than the 40-year old technology that put us on the moon.

It's a totally reflexive, instinctive reaction for them. They lie when it's painfully obvious that they're lying and stupid to try, but they do it anyway.

    Similarly, the instinctive reaction for an authoritarian dictatorship is to make problematic people disappear. Doesn't matter that it makes them look bad, and is stupid in demographic terms (Russia is suffering a population crunch due in great part to vast swaths of its own people being done away with by the Soviet government) or intellectual disadvantage (Soviet dogma dismissed Darwinian evolution, thus crippling any sort of progress in biological fields, to say nothing of the fact that their most intelligent citizens were always the ones most likely to get disappeared). It was Stalin who said, "No people, no problem".

    In a way, though, this is a good thing. It means the sort of permanent national necrosis you see in 1984 or other dystopias probably can't ever develop.
