Then, make flimsily thin empty frames out of this, about 90cmX44cm in size, and then stretch aluminium foil over them, make a stack of them, say 40 pieces, and take an approach somewhat like in the “make” article which was posted above. I would use some silent 120mm fans. I’ve taken up soldering, so I’m looking forward make this run slowly, and somewhat faster when the relative humidity increases.
Questions I have are: does this make any sense whatsoever? Would the fans be able to push the air through (tell me there’s not enough information here to know). Any idea on this surely being so inefficient it cannot be worth it? A specific question I have is: would it make sense to force the flow between the plates to follow an S pattern, using baffles somewhat like in a shell-and-tube heat exchanger. Would such baffles just decrease the capacity? Would they help creating a turbulent flow? In that respect: would it help to try creating a more rugged surface of aluminium?

I think your idea will work, and it's not going to be terribly expensive to try it out.
I don't quite get the "S" curve thing... Why not just go with a longer channel?
But the most important thing is to try it out, do some tests...
You got it right the first time when you said that you were, "not hindered by much background knowledge."
I think that is the perfect state of mind with which you should proceed!
Please take photographs of your project, we'll all be very interested to see what you come up with.
