Cloud Cities

The Cloud Cities is the collective name given to the habitat facilities built to float at the edges of dense atmospheric systems such as the planet Venus; for classification purposes these facilities are also known as Atmospheric Habitats. Though these cities are not a single technology but the product of thousands of technologies working congruently. However for the sake of simplicity, these articles will overview them as entire cities and explain the components within.
The collectivley called the Venusian Cloud Cities are counted amoung the the Wonders of Sol System. The original cities were created for Venusian colonization, with the first design based on floating city systems that were used on Earth's oceans when coastal erosian began to displace land cities.
As of now there are two types of cities, with only small variations in design from one manufactured city to the next.
Recent tests have been done on concepts for a cloud city to be built on Saturn.
