40d:Windmill

The Windmill is a machine that provides power via wind on the surface of a fortress map.

Currently, the Windmill provides 40 units of power and requires 4 pieces of wood. Multiple windmills increase the power.

Getting Power Out Of A Windmill

To get some useful power out of a windmill:

1. Place the mill
2. Excavate a path under it to the center of its base. (1 z-level down)
3. Add either a vertical axle or gear assembly there, which will have power.

Getting Power Back To The Surface

1. Build a windmill at level 0 (L-0).
2. On the level beneath it, (L-1), place a gear assembly (GA1) below the center point, use 'q' to verify that it has power.
3. Place a horizontal axle (HA1) next to GA1.
4. then build GA2 next to HA1. It should look like *=*. (GA1-HA1-GA2), All of these should have power.
5. Back on the ground level, build a 1x1 channel above GA2.
6. Place GA3 on the channel, so that it sits directly on top of GA2.
7. GA3 is now on the surface level, and you can use horizontal axles to transmit power in the regular directions across the surface.
