Hey guys, I was reading Cosmos by Carol Sagan and had a thought about terraforming Venus. Would it be possible to suspend a tube from geocentric orbit down to the high press / high heat region of Venus to vent it directly into space. Similar to a space elevator concept, except with the purpose of ventilation instead of moving an elevator. The idea would be to use the high pressure and heat to create an upward draft. Additionally, using two vents oposite each other could add rotation to the planet by creating a locomotion effect similar to an Aeolipile / Hero engine.

The goal would be to reduce O2 levels to the point that it stems the run away greenhouse effect lowering temperatures as well as reducing atmospheric pressure. And potentially increasing planetary rotation using the locomotive force of the pressure escaping the planet.

Thoughts? Can you guys help me with the math. How long would this tube need to be? How much upward draft would the Venusian atmosphere create. How much external and internal pressure would the tube need to be able to withstand.
