Geothermal

Geothermal was an early power module planned for Astroneer. It was designed to be placed directly on top of geothermal vents and provide a passive, continuous flow of energy, functioning in a role similar to the RTG. The item never made it into the first public release and was removed before launch because it did not work correctly and the vents themselves were failing.

As a removed feature, Geothermal is only relevant in the context of Astroneer’s early development and cut content. It shows that the game once experimented with a terrain-dependent power source tied to natural planet features, rather than the later portable and manufactured power systems. A prototype version was visible in early development materials, indicating that the concept was present for some time before being discarded.

• Geothermal was intended to sit on geothermal vents.
• It produced passive energy rather than requiring fuel input.
• Its function overlapped conceptually with later long-term power solutions such as the RTG.
• It was removed before the game’s first public release.
• The stated reason for removal was that it did not function properly, alongside issues with the vents.
