This Steam generator will self start from a base state of 2kSU and build up to 65kSU once enough lava gathers in the cauldrons.

***Water containment not present in schematic***

I tend to try to compact builds and I'm sure there is more i can do here.
I kept the water and lava pipes separated by air gaps as dropping in from schematics was problematic .
Occasionally the pumps need to be set to the proper direction when building from a schematic.

99% sure i only used Vanilla blocks and Create .5
