Hello there! This is my first post on this forum after a few days of lurking, but you guys seem nice. It's really cool what a clever DF player can do with some well-placed mechanisms. I was thinking that could be greatly expanded on. Here are some of my totally wild suggestions:
Conveyor belts: Unpowered, long lines of these would help dwarves carry heavy objects faster, by just pushing them along on top of the belt. Powered, they would drag any object on it at a set speed from the beginning of the belt to a square at the end. Useful for setting a Dump zone at the beginning to shorten the distance dwarves would have to travel to get rid of stones, letting the belt push them out of the fortress or into a chasm. Longer belts with naturally require more power.
Elevator: Fancy way to traverse Z-levels, especially when there are a lot. Could either be dwarf-powered or mechanized. Probably suggested beforehand.
Boiler: Steam power, hell yeah! It'd generate more power than a water wheel or windmill, but would require both heat and water to operate. A dwarf on bucket (or cleverly placed pump) and coke duty should do for a while. Place it on magma and you're really cooking with...well, magma.
Pipelines: Not just for screw pumps anymore! Attach some to a pump to get water into your boiler or underground farm, or run some from your boiler along a river to thaw it out during winter. Pass them inside of walls or under floors.
Rain catcher: A strategically positioned barrel, pretty much. Good for forts which lack water sources. The function is obvious.
Steam Cannon!: Or...maybe not.
Now, the alchemists's lab, at this moment is only used to make the not-implemented-as-of-yet soap bar, which in my opinion can be done just as well in a kitchen. I'm a bit disappointed, as I was expecting something more exiting.
But! It has potential, don't you think?
Black powder: Blast mining, hellz yeah! Or make it into traps, and possibly deadly catapult ammo! Of course, this wouldn't be easy to create in the game. Naturally, this has been suggested, but I'm just trying to think of things to add to the alchemist's lab.
Potions: Using the Extracts and other chemicals, as well as glass vials, the alchemist can produce brews that create various effects, possibly for use in tanning or drugs that help an injured dwarf heal faster.
Soap:
Urist McSoapmaker feverishly worked the ivory bar against the roughly hewn stone floor, occasionally dipping it into his oaken bucket of water. The lumbering footsteps drew closer, and he knew that soon the...thing would come into view. Satisfied, he left his instruments and ran around the corner, peering fearfully around it. The
T stepped into the slippery square, stopped and an electric blue X began to flash over it. Sighting in relief, Urist used the time he bought himself to run.
Just a suggestion...
