#26 Re: Interplanetary transportation » Space Towers and Skyhooks » 2018-10-20 11:09:00

I don't think we want to be taking that much material from the planet to launch into space. Even IF you could get a space hook to work it would take massive numbers of launches to do it and would take massive amount of energy to keep it in orbit. It would also be a gigantic menace that could kill millions of people if it fell.    Better to just launch the stuff.     A rail gun remains the most possible thing we could do to launch materials from Earth and probably the least expensive.      Maybe someday we can figure out how to make a "gravity shield" that interferes with gravity, but it would have to use some sort of energy field to bend gravity or interfere with it somehow, and then turn it off when you hit a high enough orbit for 1000mph to work.  But that might be absolutely impossible, along with warp drive, wormholes,  teleportation and other nice thing we are shown in sci-fi as plot devices and problem solvers.   

I think the reality is, we are going to get 99% of our materials from space at easy, low G locations at some point, no need to launch stuff from Earth and deplete our resources.    Once robots take off and can mine and produce materials 24/7, as well as replicate things, sky hooks and space elevators will go back to being quaint ideas from old fiction stories.

Mexico news kept saying that it found a fallen satellite and I kept trying to correct them, explaining that it was just a shroud from an Ariane rocket launch, but of course, they kept repeating it over and over.

I wonder if a version of this could be used on Venus. I think there is a minimal size to a long duration robot on Venus, as it will have to actively cool itself with refrigeration, could it be human sized, or would it have to be an "Iron Giant" with cooling equipment on its back?

This makes far more sense than EVAs.   That new space pod idea just doesn't make any sense when we have haptic telepresence capability in basic video games for kids.

#29 Re: Interplanetary transportation » Mission to Venus » 2018-10-18 20:24:09

If you're floating in the clouds, you have real gravity.   That's the only advantage really to floating in the Venusian atmosphere.    Well, easy access to oxygen if you need more I suppose.

I also think sky hooks are silly.   They'd have to be fricken enormous and then the "hooking" and "unhooking" part would be dicey as hell.  If they ever fell to Earth, it would be cataclysmic and you'd still have to keep boosting the thing which would suck up huge amounts of offsetting energy.   I don't even know why they bother to research things things except that I would too if government gave me $millions to do it.

Space elevators are only slightly less fanciful, though you'd have to come up with a material that has essentially infinite tensile strength.  And even if you could, something in orbit is going to hit it one day, or a plane and all hell would break loose.

Far less fanciful perhaps (but still insanely expensive) would be a rail gun, perhaps built up the side of a very tall mountain, that could accelerate payloads to extreme speeds and then spit it out 4-6 miles above sea level where the air is a bit thinner.   

Keep in mind that, while we could float 50km above the surface in theory at be at 14PSI, the winds are faster than a Cat 5 hurricane.  So, that would potentially suck.  And it would be hard to stay where you wanted even if the winds were sufficiently static in direction. 

And then there's the potential problem of getting into space.  It would take about as much energy to get from 50km into orbit on Venus as it would to get from sea level to orbit on Earth, because you have to get out of the atmosphere and accelerate to about 15k-20k mph.   And do that without the benefit of a launching site.     In reality, once a balloon goes in, it's not likely coming out, and we can't even use scramjets at Venus, it would have to be rocket powered.

#30 Re: Civilization and Culture » IQ and Space Colonisation » 2018-10-18 19:22:33

Still, chances are most anyone sent is going to have a PhD and a 140+IQ.   But they will also have a back up team of everyone in the universe at Mission Control making sure they can figure out how to program the remote control and can fix the drain.

#31 Re: Human missions » robots on the surface with humans in orbit » 2018-10-18 14:32:45

There are plenty of ways to minimize the danger of micrometeorites.   And if you use materials from Phobos, a space station can be as heavy and overbuilt as you want.   Robot labor.

But it won't be until after we're all dead so.......

#33 Re: Not So Free Chat » The Constitution, not what you think it says.... » 2018-10-18 10:11:46

Fortunately, the Constitution isn't about "what I prefer".  That's what makes it great.

#34 Re: Human missions » robots on the surface with humans in orbit » 2018-10-18 08:14:30

Except that it is your body that gives you consciousness, not the data in your head.

#35 Re: Interplanetary transportation » Mission to Venus » 2018-10-18 08:02:22

The main issue with crewed missions is the cost, and I don't see any cost/benefit in doing it.   I think manned missions to Mars, Moon, Phobos, Ceres, Callisto, others have a lot  more value, though even then, robots still win the cost/benefit situation.  If we want to do anything with Venus, it's going to take a boatload of robotic drones sequestering carbon and sulphur but even then, what do you do with the O2 and almost no hydrogen?   Without terraforming, Venus might as well be a gas giant.    Except maybe as an orbital water extraction setup.  Dive in, pick up your water, slow transport to  the moon maybe.    Might be a little more efficient than blasting it off Earth.

#36 Re: Interplanetary transportation » Mission to Venus » 2018-10-18 07:56:05

I think Venus could and should be terraformed, though it would take centuries and massive numbers of robotic ships that would have to somehow be built on site or from a nearby asteroid.   Robotic blimps are definitely cool, but risking people when they can be safer in orbit seems a bit odd to me.  Though I guess if you're in Venus orbit, you're still have a risk of being burned to death no matter what.    The amount of material that would have to be sequestered is ridiculous.

#37 Re: Not So Free Chat » Why do we give money to other countries » 2018-10-17 14:00:20

The futility of sending unConstitutional aid meets the futility of unConstitutionally stopping immigration.

#38 Re: Human missions » robots on the surface with humans in orbit » 2018-10-17 12:44:06

I actually have a basic concept for a Magnus Robot Fighter movie that is based on 1A using advanced genetic engineering to create and raise Magnus as he sees the directions things are going.     Though I don't think that The Titan makes any sense.  If we can't save Earth, we can't live on Titan.  And if we can live on Titan, we can definitely save the Earth.

I think the telepresence idea makes a lot more sense in conjunction with a 1G space station in orbit.   it would be about as fun as living in a Mars Base, but with a better view and regular gravity.  This would allow for the mining of Phobos and/or Deimos, the construction of ships and and more stations, the construction of useful communications, science and GPS satellites built right in orbit. 

It is also possible that Phobos has a lot of cave structures in it, or could provide more easy access to more useful metals.    it could be mined with the idea of creating a basic 0G station with the ingredients all around you.    It would be interesting to see what some small explosive charges would do to dust it off some areas to look for cave entrances, assuming there are some.   It supposedly is something like 30% empty.

#39 Re: Interplanetary transportation » Mission to Venus » 2018-10-17 07:47:21

There's absolutely no reason to put people into the danger of a Venusian atmosphere.   Not sure why they would want to do that.  It's a good job for probes and balloons.  You wouldn't be able to see anything or do anything.

Belter,

Let's recap your list of arguments for open borders:

1. the Constitution determines constitutionality (circular logic)

Does a contract state what is in the contract and what the rules are, or do Judges just get to imagine what it might say?

2. slurs, insults, or demonstrably false claims of racism and xenophobia (personal attacks)

If the shoe fits.  I don't like racists, bigots, xenophobes.  Sue me. 

3. claiming that people we should listen to support your argument, despite the fact that they said the exact opposite of what you stated they believed in, both in our Constitution and in The Federalist Papers explaining their thoughts and beliefs on immigration (outright lies)

Quote the Founders stating ANYWHERE that immigration is a federal responsibility.  Quote the laws they made against it, which will be difficult since that didn't happen until half a decade after every one of them was dead.

Or is this another thing where you just get to invent what they believed without anything in writing?

4. The Republican Party of 1864 agrees with your assertions (something having bean dip to do with our Constitution)

Republicans stated they were for open immigration because some absolute morons decided that maybe open immigration wasn't so good anymore because non-white people started coming.  The more things change.....

5. fact is independent of opinion (equivocation fallacy- that you have a personal belief you call a "fact" does not equate it to fact)

Yeah, except I can quote the Founders and you can't.  I studied the Constitution.  And you didn't.

Given that the 14th amendment grants citizenship to everyone who is born within the United States, then the constitutional authority granted to Congress to make laws relating to naturalisation pretty much implies that they can regulate immigration, no?


Nope.  The Feds were only ever concerned with citizenship rules, never immigration, until we decided the Chinese were strange and hard working.   Then Democrats made a special racist law against them.    The Founders believed delayed citizenship and voting was the only proper, ethical balance against too many immigrants fleeing their shit countries.  And besides, no State would ever give that level of sovereignty to a distant government, when they had just fought a war against stupid immigration laws from the King.   See Declaration of Independence.

The red is where the main boiling channels would be.  Those would cross over to the other side where the water would be collected.  If it needed to be cycled again it could go through the orange channels.  Once the water is processed and filtered, it could fill the inner channels which are separated by a vacuum slot which adds strength and insulation.    The water could be cycled as needed to distribute the warmth from the sun.    At approximately 3-5" thick (though it could be thicker), it would add some reasonable radiation protection.  The only think I can see is that this type of arrangement would only work in Earth orbit.   By the time you get to Mars, the sun would not be sufficiently hot to boil the water for purification and would likely freeze unless mirrors were used to increase the heat on the side walls, which wouldn't be a bad idea to avoid having to electrically heat the station.   If it gets to a distance where mirrors are not enough or are not practical, insulated wrap and the removal of the vacuum channel would keep stored water from freezing, and automated pressure release valves would be needed or some sort of salt injectors or ability to drain the water quickly in the event of a loss of temperature.

A 1G station in orbit around Mars and other planets would provide a healthier long term environment for workers.   And a .6G ring would help rebound before heading back to Earth.    The BFR is a cool design, but the reality is, we need at least a partial G transport, along with higher G stations at Mars, the Moon, Ceres, eventually Jupiter and Saturn and beyond.

#43 Re: Human missions » Apollo 11 REDUX » 2018-10-15 12:03:08

I keep going back to the idea that any equipment for processing fuel should be built into unmanned BFS units that could set down, unload mining robots and water tankers that would go out, retrieve water, bring it back and then the ship would fill its internal tanks with methane and O2.    If the equipment could be made small enough, it could and should be standard issue on all of the BFS units so that they could go most anywhere in the solar system and make fuel to come back.  Ceres.  A trip Europa and back, just drop a straw with a heated tip.   On to Titan and Saturn's rings for some methane and/or H2, and O2.  Triton.  Pluto.  But even if not, they could be the processing and storage facility for future manned missions.

#44 Re: Human missions » Space Station V » 2018-10-15 09:25:55

Here's an updated version of my idea for a 3D printed "skin" hull that contains active heat redistribution and a solar still for purifying water.   It would also assist in radiation mitigation and would have more substantial protection against micro meteorites, though it would be a bit more difficult to repair a substantial breach.    A full breach would require pass through several inches of water and 6 layers of alloy.   It is designed for semi-octagonal cross sections in the agricultural spokes of the station.

Your view of the Constitution is literal "creationism".   It's Flat Earth crap.   Mob rules.    Right out of the 1925 Nazi platform.    I'll stick with the Republican one from 1864 when people were more evolved -

8. Resolved, That foreign immigration, which in the past has added so much to the wealth, development of resources and increase of power to the nation, the asylum of the oppressed of all nations, should be fostered and encouraged by a liberal and just policy.

Whereas this seems to suit you more -

4. Only those who are our fellow countrymen can become citizens. Only those who have German blood, regardless of creed, can be our countrymen. Hence no Jew can be a countryman.

5. Those who are not citizens must live in Germany as foreigners and must be subject to the law of aliens.

6. The right to choose the government and determine the laws of the State shall belong only to citizens. We therefore demand that no public office, of whatever nature, whether in the central government, the province, or the municipality, shall be held by anyone who is not a citizen.

We wage war against the corrupt parliamentary administration whereby men are appointed to posts by favor of the party without regard to character and fitness.

7. We demand that the State shall above all undertake to ensure that every citizen shall have the possibility of living decently and earning a livelihood. If it should not be possible to feed the whole population, then aliens (non-citizens) must be expelled from the Reich.

8. Any further immigration of non-Germans must be prevented. We demand that all non-Germans who have entered Germany since August 2, 1914, shall be compelled to leave the Reich immediately.

Also, yes, sending people into space is unConstitutional.    NASA requires an Amendment.   Just like the Dept of Education, the very idea of which horrified James Madison, Father of the Constitution. 

“If Congress can apply money indefinitely to the general welfare, and are the sole and supreme judges of the general welfare, they may take the care of religion into their own hands; they may establish teachers in every State, county, and parish, and pay them out of the public Treasury; they may take into their own hands the education of children, establishing in like manner schools throughout the Union; they may undertake the regulation of all roads other than post roads.  In short, every thing, from the highest object of State legislation, down to the most minute object of police, would be thrown under the power of Congress; for every object I have mentioned would admit the application of money, and might be called, if Congress pleased, provisions for the general welfare.” - James Madison

Yet SCOTUS said "screw Madison, we say it means what he said it clearly doesn't mean"

I'll side with Madison over the usual political idiots on SCOTUS any day.

SCOTUS determines constitutionality, Belter.  You don't.  SCOTUS has authority to do that.  You don't.

Who gave authority to SCOTUS to interpret our Constitution and determine the constitutionality of laws?

I believe that would be the majority of Americans.  Our form of government is predicated on the consent of the governed.  We keep affirming our consent at the ballot box and the anarchists amongst us keep trying to undermine the institutions that make our country strong.

How's that for logic?

Yes, sheesh.  You don't map well.  I think you need to do a little more work on your maps of meaning.  This feedback you're getting on your ideation should be a clue that the map you're using may have some accuracy issues.  Unfortunately, I'm pretty sure you'll studiously ignore it, much like those religious fellows you referenced, because you're treating your ideation like a religion.  You thought it, so it must be correct.


Again, only the Constitution makes something constitutional or not.  SCOTUS can agree with the Constitution or disagree with it, but it doesn't change what it says.  The 10th Amendment was clear then, it is clear now.     

You simply believe in mob rules, like any typical statist.   Your thinking is boring, trite and commonplace.

#48 Re: Not So Free Chat » South of the Border Politics » 2018-10-14 20:17:58

I didn't say my knowledge carries more weight.  It is simply more accurate.    If all 9 Justices agreed, my opinion becomes meaningless.  But they almost have never all agreed.  So my opinion is precisely the same as any Supreme Court Justices, Founders, Framers and other people with more "weight".  Thomas Jefferson agrees with me.  James Madison agrees with me.  Even the Republican Party in 1864 agrees with me.
