I want to see that lava trap in action.
I'll post pics once it's done, will probably submit the whole map to the map archive once it's operational to give you guys a cool view of the thing
To give you a better idea of how ridiculous this thing will be, to pump the lava up into the reservoir will require 7 pumps per level, and the z-level height will be 20 levels high (from the bottom z-level)
7x20 = 140 pumps
Each of those needs 10 power, so 1400 power in all. Each windmill produces 20 power, so 1400/20 = 70
70 windmills just to bring the stuff up (each costing 4 wood, so the math comes out to a scary 280 wood, just about the amount you need to train a siege engineer to Great skill), not counting the extras I'll need for each gear assembly and the axles
Pumping it through each pipe will be a bit less ridiculous luckily. This is going to be huge
