Terradome

Description
A terradome is, as the name suggest, a dome in which earthly conditions are maintained, so that settlers on new planet can focus on terraforming that planet without having to be afraid of natural hazards.

Terradomes are self supportive in a way that people never run out of fresh water, air, or food. Waste water first goes through a layer of earth, under which it gets captured and sent into a system of pipes that leads to a massive water treatment plant. After all the waste is filtered out the water gets pumped to the ceiling of the terradome, where it comes out as rain. Air is simply provided through artificial photosynthesis, and food is provided through Crescuntium powered farming.

Trivia

 * The first terradome was built during hyperion's run, for use on Phoenix 3.
