RTG 

1. Science:
Abbreviation, stands for: "radioisotope thermoelectric generator"
Uses thermal energy released during the decay of radioactive isotopes (e.g. Pu238(IV)-oxid) to generate electricity.

This can work in many different ways, but is currently tested in combination with stirling engines.

Pu238(IV)-oxid releases a lot of heat, which can be used by an RTG to generate electricity.
