This is a totally new way to harness the power of wind and running water as in rivers and ocean currents. It consist mainly of two supporting wheels mounted permanently on a main shaft. Between those two wheels are four blades, or sails, that will transfer the power of wind and running water to the main shaft to make it rotate. Those sails will be mounted between the supporting wheels at 0, 90, 180 and 270 degrees by means of secondary shafts attached permanently to the center of them and free to rotate between the supporting wheels. Those secondary shafts will protrude through one of the supporting wheels and a sprocket wheel is attached to each of them. All four sprockets will be connected with a chain and positioned in such a way that the sail mounted at zero degrees will be in a vertical position and the one mounted at 180 degrees will be in a horizontal position. Sails mounted at 90 and 270 degrees will be at 45 degrees angle but in opposed orientation. The sails rotate inside the supporting wheels at half the speed by means of another set of chain and sprockets. One sprocket with the same number of teeth as the ones used to rotate the sails is attached permanently to a mast that supports the entire mechanism. Another sprocket with twice the number of teeth is attached permanently to one of the sails' shaft. These two sprockets are connected by a chain causing the sails to rotate at half the speed of the supporting wheels in the opposite direction. Therefor, when any of the four sails reaches the top position will be absolutely vertical facing the wind or the current of water when the entire mechanism is inverted.
