Abstract
A flotation platform supports a mast assembly through which a drive shaft extends having a wind driven turbine on the upper end and a propeller on the lower end situated below the water surface. The propeller is rotated by the wind turbine and causes localized water circulation in the body of water in which the mill is situated thus aerating and mixing the water in the summer and also maintaining an ice free area around the mill in winter.
