A wind machine comprises a plurality of fabrics that are removeably installed on a rotatable carrier. The carrier axis of rotation may be either horizontal or vertical. The carrier has pairs of first and second arms that support opposite ends of a fabric net. Side strands of the net may be reinforced. Each net has a loop that is supported on one carrier arm and a piece of material that is supported on the second carrier arm. The fabric piece of material has holes that receive associated studs on the carrier second arm, which is turnable. By turning the carrier second arm, a tension is imparted to the fabric. The carrier second arm is lockable to maintain the tension. Multiple panels are connected to the net for pivoting between closed and open positions. The panels resist the wind when they are in the closed position.
