ABSTRACT:
A device is located in a body of flowing water and includes a bridge supporting an electrical generator and anchors for holding the bridge stationary with respect to water flowing past that bridge. The device includes a water wheel submerged in the water beneath the bridge and which includes a plurality of arms radiating outwardly from a central arm. A hydrowing is movably attached to each radial arm and includes two flow impact sections of different surface areas. The hydrowings move with respect to the radial arms to maintain a flow area facing upstream on one side of the central arm that is larger than the flow area facing upstream on the diametrically opposite side of the central arm. This unbalanced flow area creates a force on the central arm tending to rotate that central arm. The central arm is connected to a rotor.
