Uses[edit | edit source]

  • Power Production Rate: 4 Units/s

RTGs can be placed on platforms to provide a steady stream of power at all times. They are one of the only ways to sustainably drill beneath the surface using a Rover, as sunlight does not reach beneath the surface.

Shelters and Field Shelters have low-power RTGs built-in, which cannot be removed. They provide 1U/s and 0.5U/s, respectively.

The material requirements for producing an RTG are somewhat extreme and require visiting no less than two planets simply to acquire the necessary gasses for manufacturing the required metals.

Once crafted, however, they largely satisfy all power needs and make other power sources obsolete.

Trivia[edit | edit source]

  • If one purchases all materials for crafting exclusively from a Trade Post and has already obtained all of the required gasses and processing machines beforehand, the actual Scrap cost of a single RTG is only 12 Scrap, with one Graphite and Hematite left over.
  • The RTG is based on a real life power generator that has been used in space exploration.
