Convection Schmection- Magma and Glaciers
« on: June 30, 2012, 06:42:24 pm »

So, just for an ultra-dorfy fun time, I am currently engaged in a fun-filled day of building a fort in a glacier. Above ground.

The only things below ground are the mines, tree farm, and farms. I embarked next to a volcano, so I've channeled magma to the point where my forges are now three z levels above the glacial surface with their magma supply being pulled up by a pump stack.

Sadly, I've run into a bit of a difficulty; even if an inside area is completely enclosed, it still counts as "outdoors". Meaning I've lost several dorfs that haven't gone underground for a while to, well, freezing and exposure. Despite being in a completely enclosed fortress.

I'm not precisely sure how exposure works in DF, so I was wondering if I could like, build in-floor heat with the magma in a meeting chamber on each level of my above ground fort to warm up my chilly dorfs and prevent their demise. Convection doesn't really happen, but stone does get warm next to magma, so maybe that would keep them toasty enough to survive the artic winters...

Thoughts?

Tiles with magma beneath them are a toasty 10075U. It should work.

I am trying to make chickens lay bees as eggs. So far it only produces a single "Tame Small Creature" when a hen lays bees.
Honestly at the time, I didn't see what could go wrong with crowding 80 military Dwarves into a small room with a necromancer for the purpose of making bacon.

Or better yet, tiles with magma ABOVE them.

Actually right now my fortress is seven layers high, four of which are full of magma. I'm alternating filled floors with productive ones, and come winter hopefully my dwarves will be nice and warm in their sandwich abode of doom.

Giving your Dwarf homes roofs helps. While it doesn't stop it from being treated as an above ground tile, it'll raise the temperature a bit and keep your Dwarves protected from blizzards.

Seems pretty dwarfy to me. I'm curious as to whether it works, and what the layout is. Getting any more deaths?

Are you using custom parameters? Because in my glacier forts nobody ever dies due to freezing temperatures  :'(

This has also been my experience.

How did you get a volcano on a glacier anyway?

In my experience magma needs to be kept moving to keep heating. The first iteration of my freezing trap would have the magma keeping the water from freezing slowly stop doing it's job. To solve this I had to pump it around in a circle. I'm not sure if this will apply to heating dwarves.
