GeoDome

In Simulacrum, GeoDomes are geodesic, arcological domes built over Earth cities. Their main function is to contain the cities within them and protect them from the outside environment that has been greatly altered by extreme greenhouse effect and nuclear fallout.

Technology and Capabilities
GeoDomes are large and can be nearly ten miles across and nearly 3,000 feet high. However, it takes more than one of them to cover most cities. Their skeletons are often built from lightweight but sturdy titainium alloy, and they are covered completely by numerous solar panels. These advanced solar cells are used to deflect the heat of the sun away from the city, and to also power the city itself. Their massive size is additionally supported by forcefield technology. Their mantainace is usually attended to by specialised robots.

GeoDomes are also climate regulated, and are capable of collecting water from outside storms to provide for their populations and to also make artificial rain for the plantlife that lives within.

Using early seismic detection systems, GeoDomes can be protected from earthquake damage by antigravity technology and further implementation of their forcefields.

Destruction, however, is possible. The GeoDomes built over the Megalopolis of New York City were destroyed by a massive hurricane that subsequently damaged the entire city.
