Ok so call me a deranged lunatic, but why couldn't we just build a pipe going into the CO2 layer of Venus and then have it go to Mars on the other end and transfer a bunch of CO2 from Venus to Mars, like syphoning petrol out of a car?

Siphons have a limited height in which they can work, it wouldn't work for air that is higher than the limit of the atmosphere, or between two atmospheres, regardless of if anything like that coulod be physically built. (It almost certainly couldn't)

[Anonymous No.11838792]

>>11838769
Instead of siphoning, could we just put a pump, or multiple pumps, on the pipe?

[Anonymous No.11838799]

I think I find this so intriguing because Benus would be -42C without its atmos, so by removing the right amount we could get it to the right temperature, and by adding the right amount to Mars, we could get Mars to the right temperature. If there was any more CO2 left after getting Mars nice and warm, we could build yet more pipes to Ceres and the moons of Jupiter.

>>11838766
Assuming it were feasible to transfer gases from one planet to another (which it isn't) it would be much easier to just transfer the extra CO2 being emitted on Earth to Mars.

[Anonymous No.11838803]

>>11838792
Ahh of course. It would be so easy to create a pump long mllions of kms to connect 2 planets and create an engine that could tpump gas from one end to the other.

You definetly have to be a low IQ nigger

>>11838766
you're a deranged lunatic. So venus and mars orbit at different radii. Venus orbits faster because it's closer and Mars orbits slower because it's farther. Such a pipe would break. There's also the fact that if it didn't it'd have to pass through the sun and the fact that such a pipe would be FUCKING HUGE. It takes ENORMOUS amounts of energy to move mass between planets. I forget the exact number, but somewhere in Earth orbit, a mass of gasoline has more kinetic energy than chemical energy. It TAKE HUGE AMOUNTS OF ENERGY TO MOVE STUFF BETWEEN PLANETS! And then there's the fact that you'd be moving OCEANS worth of CO2. I mean maybe you could do some crazy shit like do a bunch of gravitational sling shots and ships scoop up venus' atmosphere take it to mars for the cost of changing Mars and Venus' orbits a bit. Still it's fucking ridiculous.

[Anonymous No.11838835]

>>11838803
Wow rude
It's only 74 million miles from Venus to Mars. Way back in 1955 there were already 20 million miles of telephone wire in the United States alone.
I'm pretty sure a few measly pumps and some segments of pipe are doable.

>>11838800
Now you're thinking with pipes.
Also why would that not be feasible?

>>11838821
You can build a flexible pipe. You could also build a pipe that could detach if an obstacle was going to be coming up and then reattach after.

>a mass of gasoline has more kinetic energy than chemical energy.
That doesn't sound at all believable to me since it's possible to drive a car full of gasoline up a hill.

>>11838835
Orbit isn't about height it's about speed. Gasoline has a chemical energy density of around 46.4 MJ/kg which translates to a speed of 9633 m/s. So probably at an orbit height a bit more than low earth orbit. This table here also gives you an idea of the energy required. We can also express the 'cost' of getting to a desired orbit in terms of the change in speed from one orbit to another, and surface to LEO is about this much.

won't work. You can't liberate enough gas to make an atmosphere that won't require a pressure suit:

can we build a blackhole inside mars' core to increase the gravity so we can have a regular atmosphere?

>>11838854
Anon, you have to go back.

[Anonymous No.11838932]

>>11838912
No. And that's not the problem here. Mars can maintain a transient atmosphere for thousands of years if you can mobilize atmosphere fast enough. Even if you have losses due to solar wind. The problem here is that there's not enough easily extractable CO2 to make an atmosphere. There is harder to extract CO2, but mobilizing it requires large scale strip mining of the martian surface. An excavation and rock processing operation on the scale of continents is just not something that's possible any time soon. Because building all the equipment requires much more resources than humanity as a whole has. Although self-replicating machines might be our best bet at attempting such operation.

the poles don't provide enough CO2. Vaporizing them would provide 0.6% of an earth like atmosphere:

The pipe is still straight up retarded. It's gonna require materials much stronger than what currently exist. It's gonna be HUGE. You have everything you need to make an atmosphere in the dirt on Mars, it just takes more effort than our economy can currently support. Unless of course you can make self replicating machines.

>>11838970
>The pipe is still straight up retarded.
So it's the only hope we've got and we need a team of mavericks who are willing to go off the book?
Why would it need to be strong? You just make it longer than the maximum distance so it never snaps taught, and maybe have little bitty holes on the side that can open to release CO2 from inside the pipe to steer it. I'm not some literal who just sitting here in my living room eating rice and trying to throw ideas at the wall.
What I mean is, have little holes along the whole length of the thing to steer.

Use the CO2 to make giant balls of dry ice in orbit around Venus, then push them on a trajectory to collide with mars.

[Anonymous No.11839015]

>>11838993
The average distance is 119,740,000km, so I'd say 239,480,000km.
We could also make a smaller, more cuqq like pipe that could deliver the gas when the planets were close.
But the dream would be about 250 million glorious kms of pipe

won't work. There are not significant quantities of liquid water on Mars for said microbes to live in.

[Anonymous No.11839205]

>>11838766
I get that everybody is shitposting here, but you would actually get a flow of liquid from the lightest gravity well to the lowest. That is exactly what siphoning does. The only problem is that the planets have relative velocities and rotations to each other, which probably fucks over the system. But figuring out how a the fluid mechanics of a siphon work between moving and rotating unequal spheres is an entirely nontrivial problem and none of you nerds have any idea of what would happen. If you figured the equations out you'd probably be able to publish it in PRE

Only if it remains a liquid which it wouldn't, it would vaporize at the pressure drops.
So no, it wouldn't work, in any way, in any hypothetical scenario. At all.

[Anonymous No.11839764]

It would work with ionic liquids as they have no vapor pressure.

Okay retard OP.

Google 'space elevator'. Learn why it is a great idea and why we can't build one (no known material strong enough to reach into space without breaking under its own weight) . And that's just an elevator into earth's orbit.

Now apply what you have learnt to your dumbass idea.

[Anonymous No.11840013]

Once when I was a kid, I had the idea for a device to breathe underwater. So my dad took me to target and Home Depot, and I assembled a device that was a floating boogie board (pool float thing) with a 2L bottle to take in air through a hole in the middle attached to a hose, and a snorkel at the end of the hose.

We managed to get it watertight and you could breathe on land or at the surface, but even at the bottom of the pool, you couldn’t take in enough air through the thing to breathe. The pressure underwater was too much; I learned that for real underwater diving, you need a machine to compress the air.

This would suffer from the same flaw, even though there’s the pressure and concentration differential from Venus to Mars, it’s not anywhere near enough for the gases to flow through the vacuum of space in a flexible tube. You’d need a rigid pipe, which brings all its own set of configurational problems, as well as a pump station on Venus
