We need to move venus outwards to 90 million miles

That's not eliminating extra atmosphere.

The O2 is good for breathing and is highly reactive so combining it with other elements would be simple, and if one of those elements were hydrogen, bingo, fuel and the waste product would be water. Win, win, win.

You can't breathe under the crushing pressure of the atmosphere of Venus.

You can't breathe under the crushing pressure of the atmosphere of Venus.

The pressure is irrelevant, it is the noxious atmosphere that is the issue. Breathing sulfuric acid is a problem regardless of the pressure.

 

[Captain Caveman]

We need to move venus outwards to 90 million miles using massive solar sails.. Solar sails hundreds of miles in size causing displacement that would allow for the planet to drift outwards. This would probably take hundreds of years, but we could place the planet into a cooler orbit and terraform the atmosphere into a more habitual one.


Ruling over two similar sized planets would be nice.

The theory behind it is probably there, the ability to do it isn't.

Well, the pressure will kill you. Kind of relevant.

How?

 

[Fort Fun Indiana]

How?

It's like being 3000 feet underwater.

 

[alang1216]

There is no theory behind it, only dreams.

 

[alang1216]

Doesn't seem to bother the fish.

 

[Toddsterpatriot]

How?

Squish you.
Suffocate you.

 

[Fort Fun Indiana]

Doesn't seem to bother the fish.

And being on dry land doesn't bother humans. Fish, nassomuch.

Yes, being 3000 feet underwater would kill you pretty quickly.

 

[alang1216]

Squish you.

no, unless you tried to hold your breatth.

Suffocate you.

water would but an oxygen atmosphere? nope.

 

[Fort Fun Indiana]

no, unless you tried to hold your breatth.


water would but an oxygen atmosphere? nope.

It sure would. You need to think this through. You would not be able to draw breath.

 

[alang1216]

I'm not talking about being underwater, only about being in a very dense but Earth-like atmosphere.

 

[alang1216]

It sure would. You need to think this through. You would not be able to draw breath.

Why so? Please explain.

 

[Fort Fun Indiana]

That's irrelevant. The pressure is what matters. That's how thick the atmosphere is on Venus.

 

[Fort Fun Indiana]

Why so? Please explain.

Because you don't have the strength to expand your lungs against 1350 psi of pressure.

Also, your eardrums would implode.

 

[ReinyDays]

some would be ejected, some would fall into the sun or others planets and some would fall into orbit around the sun or a planet.

All the molecules would have the same momentum in the same direction ...

Split the CO2 into oxygen and coal (or diamond?)

That's what the bacteria would do ... except the carbon would be used as food ... either for building structural members or as energy to build structural members ... once the photosynthesis starts building up oxygen we can start introducing respiratory microbes ... like green algae ...

 

[ReinyDays]

Why so? Please explain.

What the egg-heads call "adiabatic heating" ... if we increase pressure, temperature must also increase, without any exchange of energy ... plus carbon dioxide is 1.68 times denser that dry air ... all adds up to boiling water off ... humans can't survive ...

Space probes do not survive ... even when engineered to do so ...

You need a physics refresher course. If you were suddenly dropped into the terraformed atmosphere of Venus you would have problems but if you descended slowly, and the air in your lungs was already at 1350 psi of pressure breathing would be as easy as it would be at 15 psi. It is the pressure differential that matters, not the pressure. (There might be some issues as to how gases in our bodies function at great pressure but no one has touched on those issues yet.)
