Su -

: These generate sU based on the number of sail blocks attached. They are excellent for consistent, passive power without requiring fuel like coal or lava.

: Players use magma crucibles or automated lava farms to keep blaze burners fueled indefinitely, maintaining high-level steam engine output. : These generate sU based on the number

: A reliable early-to-mid-game source. Large water wheels provide more torque, and their output can be maximized by ensuring water flows over as many sides as possible. : A reliable early-to-mid-game source

Different power sources provide varying amounts of sU, typically influenced by the speed of rotation (RPM). : These are the most powerful late-game sources

: These are the most powerful late-game sources. A level 18 boiler setup can generate over 1.1 million sU . Each individual steam engine extracts up to 16,384 sU , though output drops if the boiler's fuel or water supply is insufficient.

For high-demand factories, players often build self-sufficient power stations:

: You can track your total production using a Stressometer . For a professional look, connect it to a Display Link to show the live sU count on a display board.
