We just got finished with the annual falling of annoying “cotton” from nearby cottonwood trees. I hate this stuff.

We do our best to sweep it up, but then it falls again. Eventually it stops after a couple of weeks, but not before coating our yard and even parts of our garage in white fluff.

Any ideas how to deal with this stuff?

I was thinking a gigantic fan that sucks the stuff in and funnels it into a computer-controlled cotton gin, that uses it to make shirts.
