A Borg alcove was a device used by Borg drones for regeneration. When the Borg drones were not needed for immediate tasks, it was used as a drone storage device by the Borg Collective.
Basic purpose[]
When the Borg had assimilated individuals who were of a young age, they were placed in a maturation chamber until they reached the age of a thirteen year old human, or an equivalent developmental stage of other species. From that age on a drone would make use of an alcove which was specifically attuned for the individual drone, although minor adjustments could be made to accommodate use by other drones. The drone would then return to the alcove on a semi-regular basis for the purpose of regenerating mental, physical and electromechanical energies spent through normal activity.
