Haven't seen the video yet, but I've been placing our box fan facing outward in the room adjoining our bedroom and opening a window beside the bed. It feels like it's blowing hot air out and sucking cold air in but I could be wrong.
EDIT: incredible!! I'd have never thought to move the fan away from the window but it makes so much sense. I wonder if it could be related to Bernoulli's Principle as well? I'll be giving this a shot tonight when the temperature drops again. I'm thinking I can set up our smaller fan back from the window and use the box fan to move air from one air of the house to the next.
UPDATE: I gave it a shot with the smaller fan pulled back from the window about one and a half feet (I didn't have anything to rest it on to move it further back) and there was very little air movement. I tried with the box fan pulled back as well and it was the same. So for last night I just put the box fan back in the window because I was roasting XD
