Terraforming Venus

Discussions focus on applying a CO2 processing technology to terraform Venus's thick atmosphere, with comparisons to Mars colonization and ideas for floating habitats at habitable altitudes.

Doesn't Venus's thick atmosphere make it different from trying to do it over Earth?

I wonder if it would work in Venus atmosphere?

I didn't understand your comment until I glanced at the wikipedia article for the atmosphere of Venus[1]. With a surface air pressure of 92x and carbon dioxide making 96.5% of the atmosphere, the surface of Venus is a no-go even before considering the extreme winds.>The atmosphere of Venus is much denser and hotter than that of Earth. [...] The main atmospheric gases are carbon dioxide and nitrogen. Other chemical compounds are present only in trace amounts.>Despite the harsh co

It is theorized that Venus once had an Earth like atmosphere. Venus has virtually no magnetic field unlike Earth. Without the protection of something like the Van Allen radiation belt the Sun would have easily blown off any thin high density atmosphere and eventually cook off any surface level hydrocarbons into a thick hazy atmosphere with a super greenhouse effect. Any terraforming effort would have to take that into account and capture atmospheric sulfur.

Would this be useful for terraforming Venus?

We know very little about Venus. Unlike most people that think that Mars is a future human world, I think that either spacecraft or Venus will be our secondary homes in this solar system. All it takes is to get 40 kms off the ground in Venus and a human could walk outside. All you would need is oxygen, which is already trivially supplied with today's technology.If we bio-engineered some plants to create pockets of lighter gas they could float in the air. Energy generation would be easy b

Would this be useful for terraforming Venus as well?

At current technology level Mars seems an easier option. The problem with Venus is an atmosphere containing sulfuric acid and winds reaching 300 km/h, where failure results in a descent to an approximation of hell.

Could we do this on Venus to start terraforming?

Could we run this process on Venus for terraforming?
