Historically Wind machines were all EOT’s (Engine on Top) and they used WW2 surplus aeroplane propellers. As these ran out; extruded alloy blades were designed. The original EOT’s were in fact quite an efficient design. They blew away from the tower and used a smaller engine to achieve a greater area of frost protection than most modern Wind Machines do today.
