The RTG provides constant and reliable electricity for spacecraft. Its weight/power ratio is a lot worse than that of solar panels (unless you are very far away from the sun - Dres and beyond), but RTGs have the advantage that they do not require direct sunlight, so they still work when on the night side of a planet.

The design of the PB-NUK Radioisotope Thermoelectric Generator is based on those used on the Pioneer 10 and 11 probes.


The Radioisotope Thermoelectric Generator is useful for purposes such as:

  • Traveling so far away from the sun that solar panels become insufficient.
  • Operating energy-consuming equipment on the night-side of a celestial body.
  • Removing the need to take special action to replenish electrical power stores.
  • Emergency backup for a stronger primary power supply.

Product description

Through exploitation of the natural decay of Blutonium-238, this elegantly simple power generator can provide consistent, stable power for decades. It's also waterproof and dishwasher-safe.


  • Mass reduced from 0.175 to 0.08, power output reduced from 1 E/s to 0.75 E/s.
  • Initial Release
