Compact 3x5x5 Lv3 Steam Engine [SELF SUSTAINING]

The small form factor of this engine makes it perfect for earlygame bases, smaller vehicles, simple factories, and many other use cases.

To jumpstart, simply connect a small water wheel, then use a crank.

...Alternatively, you can connect two small cogwheels to the large cog (1 on each side), then place two cranks on the cogs. Quickly flick between the two cranks. If you are fast and consistent enough, the machine will jumpstart into passive mode.
