Domed city

In most descriptions, the dome is airtight and pressurized, creating a habitat that can be controlled for air temperature, composition and quality, typically due to an external atmosphere (or lack thereof) that is inimical to habitation for one or more reasons.

Domed cities have been a fixture of science fiction and futurology since the early 20th century, offer inspirations for potential utopias[1] and may be situated on Earth, a moon or other planet.

Where other science fiction stories emphasize the vast expanse of the universe, the domed city places limits on its inhabitants, with the subtext that chaos will ensue if they interact with the world outside.

[17] Seward's Success, Alaska, was a domed city proposed in 1968 and designed to hold over 40,000 people along with commercial, recreational and office space.

[18] Intended to capitalize on the economic boom following the discovery of oil in northern Alaska, the project was canceled in 1972 due to delays in constructing the Trans-Alaska Pipeline.

[19] In order to test whether an artificial closed ecological system was feasible, Biosphere 2 (a complex of interconnected domes and glass pyramids) was constructed in the late 1980s.
