Is there currently any way to duplicate liquids? I have embarked on a glacier biome and need a mist generator for my dwarves to not go insane. I have a single 7/7 tile of water boxed in with a forbidden door. I'm underground because of zombies and need a way to get more water without more magma/booze explosions. (Yes, I did use tin screw pumps, and yes, the magma did overflow into the booze stockpile. Thankfully nobody was killed in the explosions)

Well I know the wiki states that caving in ice can create pools of water, but it's iffy/buggy.

I thought water in a mist generator couldn't evaporate, since it always sticks in a clump of 7/7.

I think the question is more about how to make water, not how to prevent the existing water from evaporating.  I can't find the thread now, but I know there was someone that created a water generator in a glacier environment.  The idea was something like this:

Code: [Select]

#Iwww
 M
The "I" is an exposed ice tile, so that it would re-freeze.
"M" is magma that was flowing.  The trick (which I don't remember how it was done) is that the magma had to be flowing at the "M", and then moved away.  While it was flowing, the "I" would melt and flow to the "w"s.  Then, when the magma was moved off, whatever was left at "I" would re-freeze into a (full size) block of ice.  Be aware though, that the original designer had water being generated quickly.

I've read somewhere that 1/7 water that freezes melts to 7/7 water

Yeah, that's how the design in the post before yours works.

As for how to switch quickly between flow and no flow... Perhaps a screw pump linked to its power source by a gear linked to a repeater?

Wrong - 1/7 water freezes to an "ice floor" and melts back to 1/7 water, but 2/7 water freezes to an ice wall and melts back to 7/7 water.

well having heard the numbers from you I can treat with a great deal more veracity, thank you

So an exposed tile of 2/7 freeze and melts into 7/7 water.

Interesting...

Can dwarves and animals see through glass walls/glass block walls? Will they attack creatures behind these walls? I do have a captured dragon (thank god for cavein traps) and I'm wondering if I could just use a glass wall instead of dropping tame creatures behind fortifications at it. Would it heat tiles above? True !science! Must be done.

All walls are opaque and impassable, regardless of their material. If you want a wall that creatures can see through (but not attack through), you can use a Window, but building destroyers will be able to destroy it.
