I can't imagine why a CmeBrew style fan used as an attic fan wouldn't save more than it cost to make in a warm region in a year or 2.

This is a 20" box fan blade on a $20 treadmill motor, run straight from a 17W or 32W solar panel, no battery.  I know it's a huge difference, but I don't remember.

Is this the "1000% percent more efficient" something fan that I've seen on here?  I thought that was interesting when I saw it.

You know - my parents' treadmill just died, and craigslist seems to be "treadmill-heavy" right now.
