Does the Ettridge Wind Turbine have to be mounted on a tower ?
The Ettridge Wind Turbine is the only wind turbine that can operate at ground level, simply because it works on a sail, spinnaker principle, and as we all know sailing ships and yachts work at sea level. Naturally the clean air movement and constant direction of the wind is desirable, and a domestic unit installed on the roof of a house would be better than ground level, provided there are no tall trees planted around the house. A commercial unit located near the top or on the top of a hill would have no more visual impact than a shed or water tank. Painted in an appropriate color ( green or light blue ) it would be difficult to see. The small propeller wind turbines are mounted at the top of masts or towers, with a minimum height of 40 feet =(12 meters) and can be much higher, while commercial units, have towers 80-130 ft =( 24-40 meters).
