Biofuel Generator
A large pot that can convert organic matter into fuel.
The Biofuel Generator is an electrical device in Rust that draws 5 rW of power while it runs. It has 1 input and 1 output to connect, and 500 health once placed. You craft it at a Level 1 Workbench, and its blueprint costs 40 scrap to research.
About the Biofuel Generator
Its inventory has 4 slots. Destroyed, it drops what it holds.
Of everything on its raid list, the Satchel Charge costs the least sulfur: 2 of them destroy it for 960 sulfur in all. Without a tool cupboard covering it, it starts to decay after 2 days, then goes from full health to nothing in 4 days outdoors; a repair resets the wait.
On the tech tree it sits behind 4 other unlocks: Animal Fence Gate, Animal Fence, Large Planter Box and Water Bucket.
How much power the Biofuel Generator uses
At full output, one generator runs this many of them at once: 4 on a Large Solar Panel, 6 on a Water Wheel, 8 on a Small Generator and 30 on a Wind Turbine. A fully charged battery keeps one running for 1.3 hours on a Small Rechargeable Battery, 30 hours on a Medium Rechargeable Battery and 3.3 days on a Large Rechargeable Battery.
How to craft the Biofuel Generator
Crafting one takes 15 seconds at a Level 1 Workbench and costs 250 × Metal Fragments and 150 × Wood.

150 Biofuel processing
Turns food into Low Grade Fuel while it is powered and stirred: one fuel for every 40 calories, one fuel every 36s. A 10s stir is good for 150 fuel.
It takes 123 items. The Fuel Inputs tab lists each one with the fuel it makes.
How to get the Biofuel Generator blueprint
Research it for 40 scrap, or unlock it on the Level 1 tech tree for 5 Blueprint Fragments in total.

A full repair at a Repair Bench costs 51 × Metal Fragments and 31 × Wood, and you need its blueprint.

×31 Reduction is how much of that damage type never lands. Damage taken is the rest: at 50% reduction a hit for 100 does 50. A negative reduction means the hit lands harder than it would bare.
