The geothermal generator is a power generator that can be built on top of a steam geyser to convert natural heat into electrical power, providing a constant 3600W. Steam geysers are randomly generated per map, sometimes close to each other, others scattered towards the edges or center. Colonies are often seen built in their proximity from early days for future benefit.
It can be built indoors, but this causes heat buildup and eventually fire. A prevention method is to leave an open path towards outside or intentionally unroof the setup. Vents can be used to pipe the heat into other rooms. An open door will also release some of the heat from its room. However, in cold biomes, the increased temperature becomes beneficial as heat is needed instead. The amount of heat it provides is only a little more than a normal heater.
Geothermal generators have a beauty score of -30.
If closed under roof it can heat up to 8 rooms of 6x6 placed symmetrically around it with a 1 tile corridor in between.
A geothermal generator and 2 batteries can power a sun lamp and full set of hydroponics basins.
Geothermal generators are excellent as a sustainable power source, providing permanent, free energy. These should be researched after fabrication to provide free power for your growing base. As they usually make up a significant portion of a colony's power generation and geysers can spawn inopportune locations, care should be taken to defend them from destruction.
