I had my basement window removed and put in glass blocks (Which are better). They sell an exhaust fan (Single or Double) unit which works on a switch. The large one I baught from Menards. It one of thoes super exhuast fands put over a large stove. Not your regular home exhaust fan. This is close to industrail or resturant size. I only baught the fan and not the external housing as that was well over a $1000. If I remember right I think I paid only $200 for it. It's a Broan and it puts out 410 CFM.
