Sure, with dry outdoor air, but this version uses no electrical power:

And this version would only require sun, vs dry outdoor air:

The FSEC attic is only hot during the day, when it evaporates water
from the dessicant.

My current dehumidifier is well over 20 years old - mabee even 30. The
fan went bad a few years ago and I got one at a surplus shop for $5.
I would never do without one here in Southern Ontario in the summer.

We use one in the office too, next to the copier, to prevent the paper
from getting "soggy" and jamming all the time. Threw out a 30 year old
one that was getting noisy again last fall, now I need to get another
one.
