The Medium Generator, also referred to as "Coal Generator" is one of the Generators in Astroneer and produces power when consuming Coal.
Once placed on two adjacent slots on a module or vehicle in a network and fed with one stack of Coal, the generator will convert it over time into energy. It will continue to generate power until depleting resources and will therefore waste all overproduction if there is no free capacity in available batteries, but can be toggled on or off using the action key. It is recommended to use it on Exotic where coal can be found in plentiful amounts.
- It consumes Coal at a rate of 1 stack every 100 seconds, and in that time generates 50 bars of power at 1 bar every 2 seconds.
- The model used by the Medium Generator is similar in design to modules seen in the first trailer. It is possible that is is one of the oldest modules in this game.
