Alien Thermal Plant

This seems new This article contains information that is updated for the latest Experimental Version of Subnautica. Players using stable mode may find this information inaccurate.

The schematic indicates the weapon was to be powered by a separate, self-sustaining power plant, located elsewhere on the planet. The location is not listed, but there is evidence the designers intended to harness the planet's natural thermal energy.

The Precursor Thermal Power Generator is one of the four Precursor Bases. It is the smallest of the bases and will be found in the Inactive Lava Zone, within the Lava Castle. It was built around one thousand years ago.

The generator seems to be the source of power for most of the Precursor technology on the planet.

Data Bank Entry

This system converts thermal energy to electric current at 90% efficiency. Some of this energy is chemically stored onsite, while unknown mechanisms appear to be transferring most of it to remote locations elsewhere on the planet: 30% Stored for emergency use 30% Ground-to-air Weapon System 22% Primary Research Facility 11% Secondary Bio-Research Facility 7% Self-Warping Quarantine Enforcer Units The system appears to be fully automated and - given current understanding of the mechanisms involved - uninterruptible. Facility locations have been downloaded to individual memory cards to generate HUD-mounted signals.

Future Plans

• Drillable Ion crystals will be found in this base.
• The thermal generator itself will be scannable to reveal the log seen above.
• Signal for "Alien Thermal Plant".
