Atmosphere Processing Plant (Earth-7149)

"That's the Atmos? Yep, that's it. Remarkable piece of machinery, completely automated."

- - Ellen Ripley and Carter Burke

The Atmosphere Processing Plant (APP), also known as the Atmosphere Processor (AP), and Atmos, is a massive type of automated reactor developed by the Weyland-Yutani Corporation used for mining operations, becoming one of the key components for human expansion during the Domus Diaspora.

Specifications
Atmosphere Processing Plants have a cone-shaped sillhouette, reaching 1,5000 meters high and powered by 1.0 terawatt fusion reactors. Capable of converting inhospitable atmosphere with oxygen for human habitation, they conduct the native atmosphere through many levers at its base and sides. They then draw the gas through the turbine's batteries, compressing and acceleraring the atmosphere via hot mass processors within its central fusion core. The gas in the processors undergoes high electrical arcs, which ultimately heats upon ionization, before it undergoes more heated to near plasma-like temperatures in the region of 5,000°K by magnetic coils. The heat leads the molecules to dissociate into component atoms within the gas.

While the reactor of the APPs will undergo catasthropic meltdowns upon the damage or failure of its systems, the explosion that results from such an act do not render the environment with radiation. They are transported through colony ships, most notable the Phoenix-class colony ship, which feature massive structures that can transport them through normal space and slipspace to other planets.
