I built one of these systems in http://mkv25.net/dfma/browseby.php?fortressName=Workmurders with juice earlier tonight. It was constructured perfectly and coated with 2\7 magma, which instantly obliterates any flammable object I throw into it.

No smoke, no ash, no molten or burning subjects. Just poof! And gone at once. Also, if any tiles have fewer than 2\7 magma, ever, you will begin to experience evaporation and lose magma periodically until it's gone. I figured that having some 1\7 tiles floating around would let things burn longer, so i opened and closed the floodgate a few times to destroy a few units of magma. Then I left it alone, and shortly it was fully evaporated.

This idea is a sweet one which we constructed marvelously but it doesn't work, apparently. Someone fix it :O

We will have to wait for juice to upload a new image to DFMA so ya'll can see the magma incinerator we constructed. It's a big open pit at the end of the wagon road into Workmurders, and the far side of it is open to the prison, giving cellmates the option to end their lives in the magma.

I am not sure what 2/7 magma does, but 1/7 just sets things on fire. If you than throw something flamable on same place as is the firing thing, it will catch fire also. If you look at my pictures, you will see, I flooded 5 squares with 1/7 and let it evaporate. When there were cca 50 charcoals on 5 squares, I got 30 fps and nice smoke for about 2 hours of real life time.

That design is flawed. What you need to do is...

Code: [Select]

__  ______             
__D |_____| ~~~~~ |
   |F_X__X__Lava _|
   |G|
   | |
D = Door
F = Fire
G = Grate
X= Floodgate (Lavaproof, of course)

A small ammount of magma enters the fire chamber when you flip the lever, it covers what you want to burn, then sloshes down the grate and to a disposal area. After the object is on fire, you have dwarves dump the stuff you want to burn down into the hole. Probly have to do this once a month. Im pretty sure things would burn slower using this.

This is nice and safe version. Very good idea. Big problem is you need that extra space at bottom to dump excesive magma. I worry that I will not have that space.

Would there be a way of porting the 2d DF over to a Mac for those of us who use that platform?  Not important in the grand scheme of things, but it would be nice.

You can always run it on virtual machine. Maybe a bit slower but you can do it now.

Do you have a pressure plate in the area where the magma is?  Having one of those maintaining a constant 1/7 or 2/7 of magma would be perfect.  Magma at that depth will make things burn, but not swallow them immediately.  3/7 might work as well.

good idea but I still need to manage fuel manually and pulling 2 levers does not add that much work

... a nifty little subgame that models some ridiculously detailed thing like a galaxy, and then when he's confident he's got a handle on it, slowly work on integrating threads into DF.   ...

You mean like DF is going to be much more complex than a galaxy? Something that has 300 bilion stars?

What exactly is complex about a galaxy? It's just a massive list of x/y/z coordinates.

It's hard to say how difficult multithreading would be to implement in DF, without having access to the current code. It can be anything from a complete code rewrite to just minor rewrites of the target algorithms.

You know that when you have more than 2 bodies, it is analyticaly impossible to solve problem? Galaxy is solvable with statistical methods, but ... precision is getting worse and worse the further future you are solving.

Also galaxy is something more than just bunch of coordinates of bodies - there are chemical, nuclear reactions going on, collisions, life (at least on one planet), inteligent life (maybe - have not found it yet even on Earth), etc, etc, etc

Someone reads Discworld a lot, heh?

Finally some test with good results ... charcoal burns nicely long and setup suggested by Noble Digger and repaired by Dareon Clearwater works!


This method works, but it is not constant flow of smoke, its more like massive puffs in irregular intervals.

EDIT: I channeled stairs, so now there are 1x1 holes and it works much better! I also tried booze and turles as fuel and ... well I am not impressed. Turle makes quite nice puff but it is gone right away and booze makes nice little explosion but not much smoke. It seems that best is charcoal.

Also there is one major flaw of this simplified design - it can not be refueled when there is still magma. But it should be easily solved by dumping from level above or directly trough chimney. Cleaning excesive magma with water is not a good idea because of obsidian - it adds something more to care about.

Another thing - I am not sure how magma proofing works anymore, because magma destroyed my felsite floodgates (when opened) - there was molten felsite and bauxite mechanism flowing in magma. Also heat from burning 5 charcoals destroyed closed felsite floodgate (1 charcoal was OK but 5 was too much). At this point I had to suspend my experiments again because it flooded my whole smoke generator with magma.

What is that supposed to mean!!!

Don't point that thing at me!  Hey! Nononononononononoaugh! It burns! IT BURNS!

No, wait. It just stings like a mofo. Nvm.  See you later!

Well radiation does not burn ... high energy particles do not often hit your heat/pain receptors. Effects are listed here:
http://en.wikipedia.org/wiki/Radiation_poisoning#Table_of_exposure_levels_and_symptoms

And of course it can easily demage your DNA in exposed cells and therefore cause tumors and mutations.

Anyway - that artifact is AWESOME. Envy is making me cry. You are incredibly lucky to get something like this as your first artifact. All my first artifacts are rings, and picolos, etc...
