The 10000 UE store works like built-in buffering, so MK2 is a generator and a reservoir in one tile.

Mechanics

Section titled “Mechanics”

Same temperature logic as Thermal Generator, scaled up:

  • Efficiency rises as temperature approaches optimal
  • No output below 50 temp
  • Faster fuel consumption → higher burst output
  • 0.5 temp per UE (vs 0.08 on MK1) → needs high burn-value fuel

Fuel

Section titled “Fuel”

Uses the same fuel table as MK1. See the full fuel list. Low burn-value wood is much worse on MK2, so Lava Bucket, Hellstone Bar, and Coal make better staples.
