The ship's bioenergy is naturally replaced but can be depleted by the use of various machines such as the Recycler or Creator machine. The energy can be supplemented by recycling lifeforms or components, however.

Atmospheric effects are maintained in each of the environmental quadrants (terrariums) by an orb which contains condensed particles extracted from both inside and outside the ship. The regular expulsion of these particles produces the weather effects in each terrarium.
