Abstract: A wind turbine built on a vertical axle rotationally mounted within a base. A plurality of frame assemblies mounted to the axle in spaced apart radial positions where each frame assembly engages a plurality of vertically oriented peaked screens, the peaked screens arranged in radially directed side-by-side fixed positions. A plurality of light-weight flexible fabrics, each one of said flexible fabrics pivotally engaged adjacent to one of the peaked screens and of sufficient size for covering the peaked screen.

Abstract: A rain catching and screening assembly is fixed in place along a roof line of a building at adjoining roof portions, where the portions meet at an approximate right angle thereby forming a concave V-shaped roof valley. The assembly includes a rain gutter and plural gutter screens. The gutter has portions joined at a right angle adjacent to the roof valley. The screens terminate at an outer gutter lip and extend up onto the roof portions where they are wedged between roof shingles or tiles. One of the gutter screens is positioned over the two adjoining roof portions, and has a V-shaped crease in the mesh layer and fine screening layer thereby lying in contact with the adjoining roof portions in alignment with the V-shaped roof valley.

Abstract: A rain gutter screen assembly is fixed in place over a rain gutter system mounted on a building to prevent the entry of debris into the gutter system. The screen assembly has plural gutter screens with each of the gutter screens having a bead of a water phobic substance engaged on its bottom surface with the bead extending to edges of the screen. The screens are arranged in side-by-side positions such that a bead termination of each one of the beads of each one of the gutter screens is in contact with another bead termination of another one of the beads of another one of the gutter screens so that rain water is unable to bridge the screens but is forced to fall into the gutter system.

Abstract: A cover for a rain gutter is a rigid, rectangular, and planar sheet of expanded metal which has a linear bead of a hydrophobic material engaged within the sheet thickness and protruding away from, and below, the bottom surface of the sheet, the bead further extends in parallel with the long edges of the planar sheet medially over the full sheet length. The sheet may have a screen covering its top surface.

Abstract: A wind turbine with a vertical axle supporting a plurality of frame assemblies is mounted to the axle in spaced apart radial positions wherein each of the frame assemblies has a vertically oriented flat screen fixed between a pair of spaced apart struts, a stationary or rotating arm is vertically oriented and mounted between the struts and to one side of the screen, and a flexible sheet is fixedly mounted along one of its edges to the stationary arm. With a wind blowing in any direction, at least one of the flexible sheets is positioned for being blown against one of the flat screens, thereby driving the axle in rotation, and at least one of the flexible sheets is positioned for being blown away from one of the flat screens thereby lowering wind resistance.
