I've read that the atmosphere about 60 km from the surface of Venus is very similar to the atmosphere on earth (the oxygen/nitrogen/CO2 levels and pressures are about the same). If there was a way, to say, create a floating city at that elevation, what would it be like?
I understand that the surface of Venus is extremely hot due to it's thick atmosphere and it's crazy greenhouse effects, but how would the temperature and effects of UV rays be at this altitude? I'm also interested in how the gravity at this level would compare to the gravity on Earth. Are there any other issues that might arise from living there?
