Obviously not, since it took a few read-throughs to even NOTICE the reference to z-levels.
Third line of the post is: "Chain pumps are pretty ancient and would be a great answer to multi-z-level
More efficient, despite being slower? I'd like to see the math on that. How deep do the pumps have to be before a chain pump as described would be more efficient?
1 pump every 3rd tick is basically 3x the power required to pump, since you need 3 pumps to make up the volume.
So for the same water output, a chain pump consumes 30 + 6*Zlevels while a pumpstack consumes 10 * Zlevels.
A 8 Z pump height for a pumpstack is 80 power required, while a chain pump would require 78 power.
10 Z height: pump 100, chainpump 90.
100 Z height: pump 1000, chainpump 630.
8 levels is the break even point, anything taller than that and chain pumps are more efficient power wise.
Necroing. Is. Okay. On. The. Suggestions. Subforum.
Sorry about the TV Tropes link.
I just have to ask, why are you so hostile on this point?
When I posted this necros were frowned upon, that's the reality of the matter. Emphasizing that it's perfectly OK now
doesn't really matter.
Zilpin: I looked at rope pumps, but they are quite different from wells and you can't move liquid death with wells anyway. Though I suspect that's an oversight, what dwarf doesn't want to cart around buckets of molten earth?
