What you’ll build
Turn your kelp into a power plant that never needs coal. Build two hopper-fed lines, one with a furnace and one with a smoker. Race them, then feed dried kelp blocks back in as fuel so the plant powers itself, and crown the champion.
Finish line: Your kelp power plant runs itself and you know which line produces the most fuel per hour.
Bonus challenge: Add a third line and work out how many dried kelp blocks your whole factory could make in one real hour.

You choose

Stuck?
- Hopper pointing the wrong way? Crouch and tap the block it should feed as you place it.
- Fuel goes in from the side, items to cook go in from the top, and output comes out the bottom.
- Nothing cooking? Add a little starter fuel like coal or planks to get it going.
