Addendum to this message.
Two considerations 1. If you fit the powder pack
of sodium polyacrylate loose enough you won't have to use a high power
induction fan (like the one used on an air conditioner) you could use a
relatively low power consumption 12vdc motor based fan.
second, I don't know yet if alchohol is the best
coolant of choice as it's flamable.

Ok, I can't find a pre-fab
Hummidity filter made with this stuff anywhere online... I know that
they are made... but my google-fu is not strong on this search.
SO...
I thought about how you might make
one.
First and foremost, used product will have to
be switched out from time to time, so the main filter component will have to
be easy to get to and switch out.
Second to promote condensation and from there
condensation inside the filter unit itself it'll have to be slightly cooler
than the enviroment outside the filter... Problem... small refrigiration
units are expensive (energy use wise)
So, what I think one should do is to use a pipe
with a fan on the intake side and a normal air filter on the outflow side.
that inbetween the intake and outflow has a copper coil with a simple
fountain (12vdc) pump that pushes rubbing alchohol through the pipe at
speed. Probably accellerated via a kort like nozzle off the pump. It
wouldn't cool well enough for a air conditioner, but it should promote a
cool atmosphere inside the filter which would promote water to condense
within the filter. In the center of the coil which is inside the pipe would
be a tissue bag full of sodium polyacrylate. That once used can simply be
pulled out and replaced.
I'm thinking of taking a break from BugEye
II to prototype this. Anyone interesting in providing a testbed if I
do?
