The extractor, internally, has to be built using gears and shafts to split the rotational power it is receiving between its components. So, even though we don't have them, I can imagine 4 hypothetical machines, each with the power requirements of a single stage.
However, the hypothetical multistage machine would have to use 'magic' gearing to duplicate the way that the all-in-one extractor can share the torque between the stages.
Now, RotaryCraft has a lot of blocks. I can't believe that it would actually be in any way difficult to implement the extractor as 4 machines - each with a single input and output - and while the resulting configuration might be boring - would nonetheless be less boring that all 4 stages in one box.
Which implies to me that balance IS the only reason the extractor bundled up. And, in terms of rotarycraft machines, the extractor seems to be the only one that requires the top tier power producers. Fully powered as a single box it requires 8 (or so) max height hydrokinetic generators. Is there any reason in rotary craft to produce and use jetfuel other than to run an extractor?
That said, the individual stages in an extractor can be run for a mere 176kW. And so no, if not the physics, then the engineering of the device does not make sense.
But, given that an extractor IS 4 stages, what engineer faced with 4 machines that consume 176kW, would box them up as a packaged unit with gearing that instead requires 4MW?
Other than yourself.
As Steve, the good engineer, it it my responsibility to to and be efficient. And the only thing standing in my way are the artificial limitations you are placing in my way to prevent me automating several extractors.
In the name of balance. not science.
fix it. please.
The rigor you approached this mod with is attractive to my OCD. The extractor does not fit.
