So....with my fortress running on more than self-sufficiency (food stocks are pouring over) and a now virtually fully adamantine-clad 15-man standing army of highly trained dwarves, I'm in a cosy spot and decided to start work in a big project. The idea still is to build a giant golden tower with magma pouring from it, but for that I need to pump magma up from almost 100 levels into the earth, which
- requires a system of 100-ish pumps to be built that runs in one long line from the bottom to the top, taking into account caverns and other "fun stuff"
- these pumps must all be built from [urlhttp://df.magmawiki.com/index.php/DF2010:Magma-safe]magma safe[/url] materials, ie materials that have a melting point that is higher than than heat of regular magma. Since a pump is made from 3 components (a block, a pipe and a giant corkscrew) this is quite the task.
- it also requires energy. I can have dwarves operate each pump by hand technically speaking, but for a 100 pumps that is a titanic task (not to mention that you can't trust dwarves for shit, they may get a sudden craving for cave lobster and leave your entire operation in the dust.
). So I will resort to other energy sources.
So, first thing I had to do was to start up a production line of parts for these pumps. For this I started smelting all my now (with the adamantine) useless iron and steel armor and weapons into base materials and build a range of magma-fueld smelters and blacksmith workshops deep in the bowels of the earth.
I also started planning the power provisions. Since the river near me isn't deep enough for water wheels, I resorted to a windmill park.
I now have about 12 windmills on the surface, which are all connected to the same power 'net' through gear assemblies and producing a nice amount of power. And then...I made a retarded mistake that would set me back quite a while.
Basically, I digged out and constructed a long, loooong shaft of vertical axles and gear assemblies to transport my power deep into the earth, towards the first pumps (I wanted to run a preliminary test). The test ran fine btw, but then I realised: I DIDN'T NEED A SEPARATE (power-sapping) SUPPLY LINE TO THE BOTTOM! I can just link each pump to the one above it (which is easy as they're all close to each other by design) and then LINK ONE PUMP TOPSIDE TO THE POWER GRID AAAARRGGGH. So basically I just built an elaborate and extremely pointless power line a 100 levels down.
I ended up disconnecting it from the grid to save power. It's now completely defunct. :-/ But who knows, maybe I can still find a use for it later on?
So now I am constructing a seemingly endless row of pumps to the surface...I started at -96, at around -63 now and about to work my way around a cavern (I hope). In the meantime my hard as nails militia has slain a slew of Forgotten Beasts and a Colossus that came knocking down the front door/hung around in the caverns. I made some nice leather backpacks from one of the Forgotten Beasts' hide, which I will symbolically bestow on the militia commander.
I may even have it embroidered, in the hope that the craftsdwarf puts an image of one of my dwarves dealing the killing blow to a forgotten beast on it.
