i am some what new to dwarf fortress and was looking in to pump stacks and exsperimenrted a bit. this is what i ended up with but i have no idea why it works but i like it becase it does not lag for me, i call it the dry pump stack (to be used to kill elves).

# = wall
_ = open space
% = punp
X = stair

i havent seen it in the forums or in the wiki and i have no idea if it laggs for othere people, i would be intrested to find out if it does or not.

What, exactly, is this; and how does it work?

I don't think this would lag any more than any other single pump moving nothing; which is to say, not at all. The lag of pumping comes from all the liquid movement.

I don't get it, what is it supposed to DO exactly?

[ThatAussieGuy]

Dariush beat you to it wqaopl.  Cudos for coming up with it on your on none-the-less.  The basic theory is as there's no surface for the liquid to settle on, it just gets immediately passed up to the next pump above.

Oh, this is just an open-air pump stack? It works. IIRC, it creates a little more lag than a normal pump stack.

[ThatAussieGuy]

Really? I would've thought it'd create less because the magma didn't have time to settle and change the temperature?

thax lagg is not always a problem for me but i want to cut down on it to make more intresting constructions and have more !!FUN!!.

im just wating for a elf to walk into my emty moat cos there are no briges any where...

I don't know exactly why, I just know that testing showed that it causes more FPS slow-down than a standard pump stack.
Actually, I think it causes more lag than the improved pump stack (the less-FPS-consuming one). Can't remember how it fared against the older standard. It wasn't much of a difference, anyway.
And keep in mind that I haven't seen the thread in over a month. I think I'm correct on this, but not entirely sure.

intresting.from what i have seen  im gesing that the pumps are calculated every tic from bottom to top. so as long as each end is open the water/magma never interacts with anything in the middle. a bit like a worm hole.

Found the original thread -

And yeah, the theory is that because the magma doesn't settle, there's no recalculation of temperature.  Doesn't look like anyone proved or disproved it though.

I've experimented with open pump stacks (in a magma superweapon design) and they do spill liquids to the sides. That staircase would be splashed.

[Lectorog]

Just realized this is a top-down view. It makes a lot more sense now.

[gtmattz]

Just a little side note, now that I see what it is..  If the output at the top of that stack ever fills up, things will start getting messy REAL fast.
