re DIY...hurricane season is about a month and a half away.... thought I would pass along the final modification of the tent fan that I used to power my ceiling fan... I cut away the nose to expose more motor shaft, added a hub from an electric model plane that tightens to the motor shaft with a split collar, and attaches a 9x6 propeller... the nylon strap to the ceiling fan.. you need a counter weight on the opposite fan blade... moves considerably more air than the original foam blades, but is sharp if you run into it, and with a magnetic mount, as a stand alone wind source
