Actually, I'm wondering how hard it would be to achieve horizontal flight of liquids.  If it's possible, then we could have some terrible cave-in guns by aiming a water and magma pipe at each other...

I'm currently finishing up a prototype pressurizer as I speak - I'll first test to see if I get good pressure off of it, then I'll build a nozzle and see if I can get sideways flight.

EDIT: *yawn*  - I'm having to drain a whole volcano into my reservoir with a pump stack.

FPS is fine, but it's just a huuuuge reservoir.

How huge are we talking? The one I built for Rampartroots took a whole half year to fill.

[acetech09]

probably 100x200x3. It would've taken about 5 seasons to fill if I didn't optimize my pump stack's feeder tubes - now that I did that it went in about a season and a half.

I've heard that obsidian won't form from the collision of falling magma and falling water-- all you get is steam.

I'm not sure how valid it still is, but Urist McTzu has a "shot tower", a "dwarven hail generator" and a "pancake mixer"  set of ideas that make me believe it is in some way possible to rain stones from the sky.

If an enemy is caught in the blast, does he get shot upwards, or is that impossible with the current liquid physics?

[Girlinhat]

Dwarven physics does not allow a creature to be pushed upwards by a flow.  This is because any upward momentum is actually teleporting liquid from the pump's source, appearing at the next possible pathable location.  Because it's teleporting, there is no flow, and thus no movement caused by liquid pressure.  Only liquid spread from 7/7 to <7/7 will cause movement, and that can't happen upwards.

Eight levels.



Not a record, I'm sure... but I wasn't trying for one. Just experimenting to see if it's possible to build an anti-aircraft weapon.

[DrKillPatient]

I hadn't considered the possible use against flying creatures... If you make a single open space (like a giant window minus the glass) into your fort so fliers can come in, perhaps magma landmines on the ground underneath can be used to go flying-mount-sniping. The question is, will they get knocked out of the air by the magma, or just be slightly melted and still get past?
