Has anyone ever built anything like this?

[Guest guest]

I keep having this idea to build some kind of a tube to snake out of our

bedroom window and up on to the roof, and then over onto the roof of our

neighbord house with a blower on our end of it.. the point being to serve as

a collector for fresh air that we could pump in from a location that was at

least 20 or 30 feet removed from our building. Has anyone ever done anything

like this? The reason i ask is because since our basement is full of mold,

the air that flows in a laminar war around our building sometimes has a lot

of mold in it, and the times are unpredictable. I suspect that a 'chimney'

might work too, when the air was blowing but in the early evening, until

midnight or even later, the updraft of air in our building brings mold up

and it can get very strong..

So the only way to get fresh air is physical separation.. I'm thinking..

importing the air from elsewhere via a tube?
