This is a steam engine with two level 9 boilers. The engine is fully self-sufficient and outputs 286,720 stress units. The attached youtube video details how to operate the engine. I usually play minecraft with a random tick speed of 30 (default is 3), and the engine was built in a world with this tick speed. A higher RTS makes the drip stone fill up the lava cauldrons faster. So if you play on default RTS, you may need to expand that portion if it cannot supply enough lava, or you can also try lighting all the blaze burners with lava to give the engine a boost to help it get started up.
