So what skills do you think a character would need to have to be able to make some of these contraptions? Knowledge: Architecture/Engineering, Craft ?, Spellcraft? What would the DC's for checks to make it be like?
Something like this would be nice for my Binder Jacob to have for the town he's rebuilding but I'll need to be able to justify the construction and how to apply the output to something useful.
He has 150K GP available for additions to his stronghold.
I've already made a purchase of a decanter of endless water and a spade of plant growth for the town. My cohort has a lyre of building and my binder can supply unlimited plant based materials, in 20 cubic foot increments.
I've been playing a strategy game with D&D 3.5e rules (run by a DM), and you can really do a WHOLE LOT with all of that. IM me, so we can talk on IM, cause there is no wayyy I could conceivably say all this stuff in a well organized, cohesive post.
