We just got this baby in action! I know they are common in West Texas, but in the Florida Panhandle they are not seen much. It's a 10 foot Aermotor mill on a 50' + tower with a 3" cylinder in a 4" well that's 88' deep. In light winds I hope to get a couple of thousand gallons a day from it. If the wind is really crankin', maybe double that! It should be more than enough to keep up with evaporative loss....if the wind blows!
