A windmill generally intended to rotate in a horizontal plane about a vertical axis, includes essentially radial vanes; each which is effectively a one way valve respective to air flow; each which can enhance (or supplement) the beneficial actions of the others; and each of which vanes, in operation, effectively simulates a sailing vessel navigating a circular course in wind of constant direction. Each of said vanes includes a framework which supports a grid, which grid is the supporting means for a plurality of pivotally connected vertically aligned and overlapping light weight flexible sails, which sails are automatically rotated about said pivotal connection by the force of the wind into positions promoting the revolution of the windmill. Included with said sails are various devices as spars, springs and cords which promote and enhance their efficient automatic operation. The windmill is inherently self protecting in high winds and self regulating in speed of rotation. The windmill is shown in several embodiments and means of mounting, including which can utilize already existing structures for height and support and which float upon a body of water. Also shown are several means utilizing this invention to efficiently and inexpensively drive electrical generators, or alternators now used in automobiles, at high RPM without need of a separate step-up transmission. Discussed also is the interfacing of the electrical power generated with the existing electrical utility power lines. The windmill is shown in sizes which range from very large, for electrical generation on a commercial scale, to small sizes which can be mounted upon the roof of a household for providing electrical power directly and solely thereto. Also discussed is the use of this invention (or appropriateness) in less technologically developed, remote, or areas otherwise deficient in energy resources. Also discloses is the use of this invention to better propell sailing vessels.

A vertical-axis feathering windmill, comprising: (a) at least one open framework vane; (b) at least one flexible sheet having at least one vertical edge, said sheet rotatably held on said framework along one said edge; (c) spar means for each said sheet, comprising a plurality of resilient horizontal members attached in spaced equidistant relationship along the vertical length of said sheet and attached so that the sheet is able to billow between spars; and (d) resilient means between the sheet and spar combination and its corresponding framework vane biasing said sheet and spar combination towards the framework such that wind on the leeward side of the windmill adds to its rotation, said sheet and spar combination otherwise pivotable by the wind.
