I can personally confirm that Alaurentia has way more than one citizen. I am Alaurentian, I actually wrote the Constitution and I am a teacher there.
But this thread is not about Alaurentia, it's about the idea of a tower that could use aeronautical engineering. I just wanted to know if you guys think it's theoretically possible. Pure academical question, simple enough: can you make a tower lighter than air using Zeppelin-like structures, or are the laws of physics disagreeing?

Light and strong materials (carbon fiber reinforced with carbon nanotubes), helium filled bladders that can be inflated/deflated at will, creating a neutrally buoyant craft that could rise and sink like a submarine...
...but here's how Bucky proposed a Cloud Nine would work. A half mile (0.8 kilometer) diameter geodesic sphere would weigh only one-thousandth of the weight of the air inside of it. If the internal air were heated by either solar energy or even just the average human activity inside, it would only take a 1 degree shift in Fahrenheit over the external temperature to make the sphere float. Since the internal air would get denser when it cooled, Bucky imagined using polyethylene curtains to slow the rate that air entered the sphere. He wanted to build Cloud Nines and anchor them to mountains, or let them drift so their inhabitants could see the world. One of the more practical uses he proposed for them was as disaster sites for emergencies.
