RTG

The RTG, or Radioisotope Thermoelectric Generator, is a Power module in Astroneer. It supplies a steady stream of power.

Uses
RTGs can be placed on platforms to provide a steady stream of power at all times.

A Shelter has a low-power (1 U/s) RTG built in, which cannot be removed.

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 mundane power needs and make virtually all other power generators obsolete.

Trivia

 * 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 10.5 Scrap.
 * RTG are based on a real life power generator that have been used in space exploration.
