Hey guys! I am new to the kerbal community and really hoping y'all can help me out! I am writing a novel about life among the clouds of Venus and I need help figuring out some basic science about how people would do it. I have done quite a bit of research online but there still remains a number of questions I can't seem to answer. They are as follows: 1. What is the range of atmospheric pressure above Venus in the range of 20-50 Km? I understand that near the top would be about 1 bar. 2. What would the temperature range be like in this 20-50 km area? I have heard wildly different estimates. Some say that towards the bottom of this 20 km the temperature would be near tropical climate and that higher up, close to the 50 km, the temp would be closer to sub-polar. Then again, others have said that even near the top of this range the temp would be well above 150 Fahrenheit. This would imply that it would be even warmer the lower you go. 3. My third question should be fairly easy to clear up. The habitat design in my book mimics airships. The things I need to know are how much mass can a given quantity of air lift, and what would be the pros and cons of helium, hydrogen, and earth air. Should there be any other gases I should consider? 4. The highest mountain on Venus is about 11 km as I understand. Would it be practical to mine resources from mountain tops to fuel an expanding economy? If it wouldn't, what other options would there be? My understanding is that asteroids would be too far away to be practical and that the atmosphere wouldn't have enough elements to meet all of the expected needs. 5. How hard would it be to get water from sulfuric acid? Are there any other things I need to know? Remember, I am a noob at this and really want my book to be scientifically accurate. Thanks a ton for any help you can offer me!
