Many libertarians have wished there was a place to build a free society. Nowhere on land is this possible. Space colonies are no more than a distant dream. An ocean based society might work, but it is as yet impracticable for such a society to be truly free from control by existing governments.
Inspired by Google’s testing of network access by high altitude balloons, I asked myself why a free city couldn’t be floated high above most of the world’s dangers. I did some basic calculations and persuaded myself that it isn’t impossible. That, however, is a far cry from showing that it can be done. I should do a conceptual design, a sketch of a possible floating city that describes all of its important parts. If that goes well, it would show that it is worth putting real effort into libertaria in the sky.
This is a large undertaking, one best done by more than one mind. So I’m throwing the idea so that others may contribute if they will. I’ll post more shortly. Constructive comments — positive or negative — are welcome.
