Auto deconstruct. Is it a bug?

I'm having this problem, whenever I have a water wheel attached to a gear assembly. When I disengage the gear assembly, it continues working fine, but when I check back after a while, the water wheel has spontaneously disassembled. Is this a bug? Or is it a feature? It happens to me all the time, and I can reproduce it without fail. Anyhow, the wiki lacks notes on this issue.

Perpetual Motion

Done a few quick tests. Waterwheels and screw pumps still have the same numbers for power. Built a perpetual motion machine using the #3 reactor design which works as before. Doctorzuber 19:10, 2 April 2010 (UTC)

Also tested the Dwarven Water Reactor, as well as a mini variant. Both function fully and are repeatable. Thus, I added the two designs into the page. Jjdorf 09:27, 20 April 2010 (UTC)
The Dwarven Water Reactor is working splendidly for me, although I subsequently discovered a siege engineer standing on the intake grate, apparently just staring at it... until, to my utter astonishment, he rather self-satisfiedly wandered off with a turtle fished out of the running device! Apparently they're good for more than just power. --Onul Rigothzas 11:57, 3 July 2010 (UTC)

I have a weird one; i built a 5 waterwheel reactor to power a waterfall, with hatches over the pump uptake spots. I closed the hatches to stop the reactor, but it is still running. the lower level is all 7 water, and the upper level is dry, but the system keeps pumping out 500 power. anyone else seen this?

Perpetual motion if Goldberg were a dwarf...

I had a need to pump water out of my artificial underground lake.
I could have just built a windmill, but I figured that since I was pumping out the water anyway, I may as well have some fun with it.
Here is what I plan to build. I'll let you know how it goes...

= Pumps from south
X = Floodgate
* or * = Gear assembly

Math as follows:
Water wheels generate: 90 power x 4 wheels = 360 power
Gears consume: 5 power x 5 gears = 25 power
Pumps consume: 10 power x 3 pumps = 30 power
Net power produced: 305 power
Assuming a windmill starter motor:
Dead weight = (2 pump x 10) + (5 gears x 5) + (4 wheels x 10) = 85 power
3 windmills at full output for 120 power or 5 at half output for 100 power.
If you can't generate 85 units of wind power, add another lever to the middle of the top three gears to drop the load to 30

If you think you're going to restart them often, consider a second independent water reactor running connected to the first, to enable them to jump start each other and avoid the dodgy windmills..



Some notes...

The water source on the left of the lower two layers is the top of a larger lake. The retaining wall is there to contain the top layer. You may not need this wall, if you have other measures in place to properly control the level of the main body of water.

The top layer of the construction, if you can arrange it, should probably be the first layer below ground. This has the advantage of letting you connect windmills, should you feel the need. I wouldn't recommend putting the gearing itself on the surface... I expect it to scream target at more destructive monsters.

The red gear assemblies and floodgates are all connected to levers. I will be linking them all to separate levers, but this may be over kill for your situation.
The upshot of this linking is that you can turn the output power on and off without closing down the pumps, drain or fill the various component sections for maintainance, or selectively disable waterwheels (maybe shutdown one to build an extension?)
As I say, it may be overkill.
Although the system is self contained, and thus shouldn't be too subject to overflows, you should still take the usual precautions with the levers... in case of mad dwarf disease ;)

Should this design prove functional to specs, I'll move it to the article.
Should this design prove utterly borked up, I'll report back with revised plans.

Revision 1:
It has been pointed out to me that 1 pump is unlikely to handle the flow generated. Extra pumps and wheels added to ensure flow.
Additionally, think out how you intend to start this contraption if you want to build one. The plans leave the pumps inaccessible (for good reason on my map), so you can't manually start them or dump water in to get it going. I plan to use a windmill for a starter motor.
Oh, and I fixed the questionable math :p
