Hi everyone,

I've recently been attempting to flood my map with magma, albeit unsuccessfully.  My first attempt involved two side by side pump stacks drawing magma from two Z-levels down from the top of my magma pipe.  I powered these stacks using a small windmill farm built on a platform above the stacks.  However, I found that this quickly drained the magma pipe and cut off my supply of magma, resulting in a rather disappointing lava puddle rather than world incineration as desired.

I have therefore started on a second attempt.  This time, I'm tapping into the magma pipe a few Z-levels from the bottom of the map to prevent my pumps from running out of magma. I'm using 6 parallel pumps spanning 17 Z-levels.  However, a pump stack of this size presented the problem of powering such a monstrosity, as this will demand 1020 power.

My question to those who have made "flood the world" devices is: how does one power such a contraption?

I'm currently attempting a massive perpetual motion waterwheel farm as shown below, but I'm having major issues with maintaining theoretical peak power.

Code: [Select]

%% = pump
X = water channel
# = grate (placed over single square hole)
||| = water wheel
~ = floor

Any thoughts?

Way too complicated... all those extra mechanisms and axles and such are draining power... simply make a really long 3 tile wide channel and line up the wheels with nothing between them so as to apply the most power to the pumps,at least that's how I did it.

On the subject of generating power, is there any way to do it involving mamga (such as magmawheels)?

...Not yet.

To my knowledge you can't make a magma safe wheel, as it has to be made out of wood.

[ed boy]

but suppose I were to interfere with the raws and create "steel wood" with a high melting point, and add a reaction to turn steel in to steel wood, would that work?

Quiet everyone. There's science in the air!

[Sphalerite]

I recall this being tried with temperature turned off, and not working.  Waterwheels are hard-coded to only work with water, not magma.

If you were going to use magma for power in some manner, I'd think you'd just use some kind of steam turbine with the magma as your heat source.  However, it would have to be large, dangerous, and overly complicated to be a true dwarven power source. 

gtmattz, any chance you could make a diagram of what you mean?  I'm not quite sure I follow...seems like it'd be even more difficult to get reliable flow in a 3 tile wide channel.

use three screw pumps, its only a 20 power difference, or alternatively

3 #'s = waterwheel
% = screw pump underwater
* = gear
+ = axle
W = Water

that specific design wouldn't be enough, the wheels would generate 900 power, (-30 for the pumps) but it should be simple to expand, or just build a few windmills to cover the extra

I made a perpetual motion powerplant for a pump stack too recently. Didn't finish the stack, and as usual my designs are more about nice layout than maximum mathmatical efficiency, but here it is (Z0, Z1, Z2):

Like modern power plants, just using MAGMA instead of a (insert fuel here) fire?

It's called a geothermal power plant. Good stuff, that. If only it could be properly implemented in DF.

Zeg, that is a magnificent construction! I will make a point to remember that, for my power plants in the future!

[HideousBeing]

Waterwheels only work if there is some kind of flow. I personally don't know what determines flow, but maybe pressurized magma (via screwpumps) could get a waterwheel going? Also... we need geothermal!!

[Itnetlolor]

I've done some research on the waterwheels, more for an aesthetic purpose; but waterwheels can move without anything flowing under them. In fact, they can be moved by windmills.

Like I said, it's not useful, by means of obtaining power, but is aesthetically pleasing depending on what you intend to do with it.

Excuse me if I strayed off topic.

EDIT:
Actually, using this method, you can feign it looking like it's powered by magma.
