I tried to have the windmill above it, next to it. Cant really find a solution. Help?

Connect with a Gear Assembly.

Thanks

Windmills deliver power to the level below it's center. Also the power generated from a windmill can be 20, 40 or sometimes 0. DF wiki also has the details. http://df.magmawiki.com/index.php/Windmill

OK, here's the layout of my cistern pumping station on the surface level:

Code: [Select]

,,,,,,,
,######
,D,,.##
,#,GP#~
,#,,P#~
,#,,~#~
######~
#~~~~~~

, = grass
# = wall
. = open space
D = door
G = gear assembly
P = screw pump (pumping from south)
~ = water


Now originally I built my windmill one z-level up, centered on the gear assembly.  I wasn't clear on the whole support thing, though...so when the pressure plate in my cistern triggered, disengaging the mechanism, the windmill collapsed.  So now I'd like to rebuild the windmill such that that won't happen the next time the gear assembly disengages.  But I can't seem to find a way to support it now.

One z-level up, I built this:

Code: [Select]

.......
.++++++
.++++++
.++.++.
.+++++.
v+++++.
++++++.
+......


...so that there's floor everywhere except the square over the gear assembly.  When I try to build a windmill centered on that square, I get, "Blocked" (indicating the center square where the hole for the windmill's output is) and "Needs ground or near machine."

I can't puzzle out exactly how this is supposed to go from the wiki.  Unlike the entry for pumps, this one has no handy isometric drawing to make it clear.  Thanks in advance.

A windmill atop a gear assembly will disassemble when the gear deactivates.  Thus, you need to place it next to the gear assembly but not directly above it.  This can be done with a vertical axle, I believe:

Code: [Select]

+ G%%+Most people using pumps will need a whole windmill farm, and thus will have the entire power grid linked up via a single gear assembly to the pump stack, so that the assembly furthest from the windmills can be deactivated and thus the windmills won't deconstruct.

Hrm...the wiki says that the power comes out through the center tile only.  Is that incorrect?  If I install a vertical axle on top of the gear assembly and then center the windmill over that vertical axle, will disengaging the assembly cause either the axle or the windmill to deconstruct?

[wuphonsreach]

The proper way to do a disengaging gear is to have the gear, on solid floor, with nothing connecting above it.  It's fine to connect to the N/S/E/W sides of such a gear, however.  For example:

(horiz axle) - (gear) - (horiz axle)

If you put the windmill on top of the gear, or a vertical axle on top of the gear, then when you flip the lever that connects to the gear, everything above the gear will deconstruct.

OK, so I really need to do something like: (side view)

 

Code: [Select]

>=<

 [*]==[*][~~]

I.e., a windmill on a gear assembly, a horizontal axle to a second gear assembly (or wouldn't it just work to have the two gear assemblies side-by-side?), and then that attached to the pump.  The switch would disengage the second gear assembly.

Does that sound right?

[Girlinhat]

Code: [Select]

>=<
 [*][*][~~]
This will suffice, actually, and will actually work.  A gear assembly consumed 5 power, the average windmill produces 20, and a pump requires 10.  Thus, 20 windmill - 5x2 gears - 10 pump = 0, and will actually run.  Adding any number of axles will drop you negative and require another windmill to function.

Alternatively, go up two levels with the Windmill, build a vertical axle to support the windmill and a gear to transfer power to the pump. Now the gear can be disengaged and the windmill will not fall.
