Generators are one of the types of Items you can craft which create Power, usually by burning some form of solid fuel, like Organic or Carbon.

The Small Generator consumes stacks of Organic to produce 1 U/s of Power.

This generator is unlocked by default, or during the tutorial, if it is not skipped. You can place it in any single slot.

It will continue to generate power until the full stack of fuel is consumed unless it is toggled off, regardless of available Battery space or lack thereof. While turned on, it will pull Organic stacks from adjacent slots if it is attached to something with multiple slots.

Medium Generator[edit | edit source]

The Medium Generator consumes stacks of Carbon to produce 3 U/s of Power.

Once researched, you can craft the Medium Generator at the Small Printer for 1 Aluminum and 1 Tungsten. You can place it on any two adjacent slots.

It will continue to generate until the entire stack of fuel is consumed, and will waste any energy that isn't stored in a battery if you do not toggle it off. It will pull Carbon from adjacent slots if possible.

RTG[edit | edit source]


The RTG, or Radioisotope Thermoelectric Generator, generates 4 U/s of Power without consuming any fuel. Once crafted, it will generate this power indefinitely.

A low-power version comes pre-installed in the Shelter. However, these cannot be removed.
