Comment on The interior of your house is hot, the exterior cool. What would the most efficient orientation be for a box fan? Pushing hot air out of a window or pulling cool air in through it?

I think you get the benefit of the airflow pulling in air along its edge to push out with it.

Like pushing a bunch of water with a broom removes not only the water in front of the broom but also more water due to surface tension and inertia
