So first of all when I blow smoke out of my bedroom window most of the time the wind pushes the smoke back into my room which is not okay. So what about getting a long tube or pipe so you stick the tube out of the window and blow smoke out of it so the smoke goes through the tube away from the window. Hard for me to explain but hope some of u understand.
I could go one just a little bit better get some 2" pvc pipe drill a hole in the wall to fit pipe add a solar powered fan/ with rechargeable battery inside the pipe with on /off switch add a flap so air can only go one way .push the button to turn on fan and exhale in the pipe ......
