Applications include: Electrical Generation, domestic water pumping, household heating, water heating, industrial and household filtration, pond aeration, fountains, farm & garden irrigation, powered wind chimes, wind driven ornaments, and more.

The Green Windmill

US Patent #5,823,749 is under exclusive worldwide License to sirius/pureprophet, ltd.

 The system consists of a horizontally suspended square rotor wheel with a square rim supporting four sails  that are linked by cables in pairs. The sails are not unlike boat sails except that they reside in a horizontal plane. The linkage of the paired sails control the sails to form preferred shapes as they revolve into and out of the wind. This control adjusts the sails in a symbiotic action that reduces friction and turbulence in the advancing sails and increases drag in the receding sails. The two opposing linked sails produce a scoop and a wing shape. The scoop holds the wind and the wing rides the wind. The linked controls additionally dampen the sail action to insure durability of the sails. 

    Because the rotor rides the wind, rather than bucks the wind, it requires minimal tower structures and is roof mountable.

    The rotor is vibration free because the tower does not interfere with the rotor. The resistance to the wind and the force acting upon the tower is directly proportional to the work load. This design is very durable indeed. It has been shown to withstand wind speeds in excess of 70 MPH without damage. Load sensitive sail cables that break under predetermined loads can protect sails, pumps and equipment in extreme conditions.
