| − | + | A '''windmill''' is a [[machine component]] that provides [[power]] via wind on the surface of a fortress map. Currently, a windmill provides 40 units of power (sometimes less, apparently depending upon the available wind) and requires 4 pieces of [[wood]]. Using multiple windmills increases the power production. | |

| − | + | To get some useful power out of a windmill: | |

| + | # [[Gear assembly|Gear assemblies]] can be used to transport the power back to the surface, if desired. | ||
| + | # You can build windmills underground if the central square in the windmill is "outside" (channel the roof away above it). | ||
| + | In rare cases, building a gear assembly before the windmill will not connect the gear assembly to the windmill. Simply reconstruct the gear assembly to connect it. | ||
| − | + | == Windmill tower == | |
| − | The "windmill tower" option is useful if you can't dig below your windmill (if, for example, there is a room or underground river there). | + | The "windmill tower" option is useful if you can't dig below your windmill (if, for example, there is a room or underground river there). This option is also often more power-efficient, as it often eliminates the need to transfer power between [[z-level]]s. |
| − | # Build a 3×3 platform | + | # Build a 3×3 platform out of floors one level above the ground floor ''(technically not needed, as long as the gear assembly is planned/built a windmill can support itself on that alone, the dwarf just needs a place to stand to built it)''. |

| − | |||
# Build the windmill on top of the platform. | # Build the windmill on top of the platform. | ||
| − | # Connect this assembly to horizontal axles, and power your machines. | + | # Directly beneath the windmill, on the ground floor, build a gear assembly. |
| − | + | # Connect this assembly to horizontal axles, and power your machines. No digging required! | |
| + | |||
| + | A windmill can also be built directly on top of a gear assembly, obviating the need for a platform. However, if switched off via lever, a windmill constructed in this fashion has a tendency to collapse. | ||
| − | + | == How to transfer power between z-levels == | |
| − | + | After you have a [[gear assembly]] in place on a level, you need to switch to the level above it and remove the floor between its tile and the tile above it. Then, build a vertical [[axle]] or a [[gear assembly]] above the first [[gear assembly]]. | |

| − | + | 2. Add Some walls to control output, and an access ramp (leaving access is a good idea)<br/> | |

| − | + | 3. add 3 floor tiles above the gap, then build your windmill<br/> | |

| − | === | + | 5. Finally, throw the lever, add your screw pump and the final wall section<br/> |

| + | === Alternatives === | ||
| + | * Skip the lever and gear and power the pump directly, "always on". | ||

| − | + | This allows water to flow past the pump when the pump is off, allowing for two pumps to use a single set of walls to contain the flowing water, with the direction based on which pump is on. It also allows for maintenance access from the pipe, at the cost of 3 extra wall sections and one extra floor. | |

| − | + | The right gear does not need to lie on the screw pump, as long as it's orthogonal to the gear that -is- placed over the pump. | |
