LOL!
Not for me! I have claustrophobia, so the more space and windows I have, the better I feel!
Gave in to the encroaching dark winter and put up some lights this afternoon -- a day early.
Ah, that explains why you didn't want to go into the atmosphere of Venus.
Rest assured, it is not a confining space, considering that the habitable area on Venus, which is fifty kilometers up in the atmosphere of the planet, is equivalent to the entire surface of planet Earth.
But that's not all!
Venus colonization will be three dimensional. For those who like warmer weather, just settle a little deeper into the soup. Going down will be like going South.
So the range of habitability is not only the equivalent of a planetary surface, but also a vertical multiplier of virtually unknown value!
The ultimate population possible on Venus could be hundreds of billions of souls! It is essentially only limited by what we can spin out of the raw materials, and they are quite simply vast.
We will make the air for flotation, and the vessel for containing it, out of the mega-ocean of carbon dioxide atmosphere on the planet. Now that is a carbon-sequestration project worthy of Humanity's attention!
Remember that here on the Flying Castle, our "windows" are made out of Aluminum OxyNitride, known as AlON. With sheet carbon fiber, and buckytube cables for strength, our floating cities will be safe and stable.
If aluminum seems to be a limiter, I suppose we'll have to mine some from other places, such as Mercury or the Jovian moons. I'll bet the streets are paved with the stuff out there.
And further note, that these multitudes of floating cities will not have to be "tethered" to an asteroid or anything. They will simply float like a cork on the ocean. They will be "cold air balloons" full of oxygen and nitrogen, which provides "lift" in Venus' carbon dioxide atmosphere.
Do you know what the worst-case scenario might be? That we would have so many cities in the sky of Venus that its surface might actually start cooling down!
