"Cloud Cities of Venus: Settling Earth's Twin": Venus is habitable 30 miles up (sort of)

Topographic Globe of Venus

 

SpaceRip presents “Cloud Cities of Venus: Settling Earth’s Twin”, by David Sky Brody, narrated by David Grinspoon.

At 30 miles altitude above Venus, the atmospheric pressure is about the same as Earth, with atmosphere of carbon dioxide and clouds of sulfuric acid.


But the film imagines cities, of blimps (maybe 1000 meters diameter) strung together.  If a large balloon is pierced at atmospheric pressure, it does not deflate immediately and it can be repaired.

Robots would be sent to the surface of Venus to mine for raw materials.

The film also discusses terraforming, even of Venus, which would take millennia.
