Magma melting ice
« on: May 01, 2009, 07:27:44 pm »

I am seriously considering embarking in a tundra area with a magma vent and no aquifer.  This is what I want to know.

I know that magma can melt ice.  But if you remove the magma later, do the ice refreeze (when exposed to air)?
Because this is what I want to do to get infinite water.

1. Carve a 2x10 room below the ice sheet for future magma chamber (20 square).
2. Carve a 2x10 room next to the ice sheet that will be melted (20 squares).
3. Setup magma chamber so it can be filled and emptied.

Code: [Select]

# - ice sheet with a magma chamber below
. - empty floor space (not exposed to surface)
H - hatch to the underground reservoir.
So the water generation sequence is...
1. Make sure hatch is closed.
2. Fill magma chamber.
3. Melted ice will spread out, creating a 3/7 depth water everywhere (assuming it melts to a depth 6)
4. Channel away roof above.
5. Empty magma chamber, wait for water to freeze into blocks.
6. Open hatch, drain water.
7. Repeat from step 1 for more water.

So, will this work?

One of the toads decided to go for a swim in the moat - presumably because he could path through the moat to my dwarves. He is not charging in, just loitering in the moat.

The toad is having a nice relaxing swim.
The goblin mounted on his back, however, is drowning.

Yeah, your setup should work. The water should refreeze when it's no longer warmed by the magma. Just make sure that you don't pump magma directly under a sheet of ice, as that will plug up your magma channel with obsidian, leading to no end of frustration.

I understood nothing, contributed nothing, but still got to win, so good game everybody else.

You should pum it directly underneath, just make sure It's not channelled.
