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), 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.

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.
