The object of this invention is to provide a large scale but low cost windmill by maximizing wind-contact out of the least cost of materials with least cost of maintenance. This is attained by making the sails (100) as large as possible using light materials such as framed fabrics or aluminum sheets, by arranging the large sails (100) to form a long life of parading sails in one direction transverse to the wind and another long line of the same kind parallel to the first line but moving to the opposite direction with which the first line makes a close loop, by using a strong light weight cable chain (101) that is tugged by the large sails and which also turns the terminal gears (102) located at the two ends of the loop, by using light weight vehicles to carry the large sails such as said Power Cable Chain (101) suspended high in the air or deep-grooved Roller Wheels (133) on rail tracks or wide-based inflatable/submersible boats (150) on the ocean, by providing a grid of strings (117 and 164) on both faces of the sail to withstand higher wind pressure, by elevating the sails high in the air thru the use of Aerial Cable Railway (132), by providing intermediary aerial supports to the cables to permit long line of construction.

A United Sail Windmill that converts wind energy into consumable energy in the form of compressed air, electricity, hydrogen gas fuel, and elevated water, and/or to serve as direct prime driving machine, comprising: A plurality of large square-faced wind sails, made of light thin metal sheets or strong light cloth/fabrics fastened together to a light strong square frame, put together in great quantities, arranged in a single file procession closed to each one after the other with a clearance to allow each sail to flip to the right or to flip to the left and moving along a long straight line in one direction and along another long straight line parallel to the first line but moving to the opposit direction-transverse to the general direction of the wind; A vertical mast for each sail, made of light strong materials such as bamboo poles or reinforced aluminum pipes, that holds the sail in place at vertical posture and at the same time serves as frame member to which the said fabric is attached to, the top end of which is reinforced by steel pipe or bar that is securely attached to the upper Power Cable Chain to serve as drive teeth of said Power Cable Chain, the bottom end of which is also reinforced by steel pipe or bar that is securely attached to the lower Power Cable Chain to serve as drive teeth of said Power Cable Chain; A pair of Power Cable made of strong rope, one at the upper level and one at the lower level as mentioned above, which are tugged by each of said large sails moving in equal pace, which form an endless drive chain having two end loops that are quite apart from each other (may be ½mile or more apart), to which the upper end and the lower end of each sail-mast are securely attached respectively, which are provided with drive teeth by clamping to same three or more vertical short bars in between the spacing of each sail-mast that are strong enough to drive the terminal gear wheels; A set of three Terminal Gear Wheels arranged in a half-hexagonal formation to hold and stretch out each of the end loops of the said upper level and the lower level Power Cable, which are driven by said Power Cable thru its drive teeth that fit into the notches on the circumferencial edges of the said Gear Wheels; Said three Terminal Gear Wheels are quite far apart from each other such that the half-hexagonal formation has a radius of 100 feet or more in order to sparate the two long parallel lines of sails away from each other for better wind contact; An Aerial-Cable Railway parallel and 1 to 3 inches close to each and every level and every line of said Power Cable, which is a high tension steel or nylon rope, suspended or held in place by tall posts or steel towers separate from the support posts for the said terminal gear wheels, which will carry the whole weight of each and every sail including the weight of the Power Cable plus the weights of the deep-grooved carrier Roller Wheels, which will hold the sails from swaying sideward due to the horizontal forces of the wind, and which will relieve the Power Cable from vertical loads at the same time prevents overloading of the Terminal Gear Wheels; A deep-grooved carrier Roller Wheel securely attached to the top end and to the bottom end of each and every sail-mast at the point where the Power Cable is also connected to each mast, which rolls on said Aerial Cable Railway carrying the sail as being pushed by the wind, the deep groove of which being at least 5 times the diameter of the Aerial Cable Railway so that it will not be de-railed during violent weather or when it is working with high speed winds; An Intermediary Suspension Support in the form of catenary wires or ropes strung in various strategic poinsts along the span length of said Aerial Railway, transverse to and connected to various strategic points of the upper level said Aerial Railway by means of an erect “T”connectors with the tip of its bottom hook being the one clamped to the said railway to lift it from below giving clear passage of the carrier roller wheels, and connected to various trategic points of the said lower level Aerial Railway by means of an inverted “T”connectors with the tip of its tail being the one clamped to said railway to lift it up from below giving clear passage of the carrier roller wheels running on the lower level Aerial Railway, the purposes of which are to provide rigid support (vertically and horizontally) to the Aerial Cable Railway to prevent sag and to provide the opportunity to build longer lines of aerial railways; A Cable-Rail Switch as illustrated by 135/136 named in the summary as “Labrador Cable-Rail Switch”, made of laminated steel plate or hardwood plate (depending upon the kind of Aerial Railway) with a deep groove to house said cable railway and provided with clipping accessories such as “U”-Bolts and clipping block, and further provided with a horizontal arc-tang to guide the deep-groove carrier roller wheel, which is clipped to the Aerial Cable Railway at the location of every Terminal Gear Wheel at the exact point where the sail-mast is forced to make a turn by the Power Cable, in order to effect smoth transfer of the sails from one Aerial Railway to the next Aerial Railway of different direction; A Terminal Power Station as per 102, 126, 124, 127 constructed at each end loop of the Power Cable (the right end and the left end of the windmill) which is an assembly comprising (a) the aforementioned set of three Terminal Gear Wheels in a Half-Hexagonal formation, (b) a vertical Gear Shaft holding each and driven by each of the said Terminal Gear Wheels, (c) a Power Gear held and driven by each of the said vertical Gear Shafts, (d) a Power Support Chain which interlocks the upper level set of three Terminal Gear Wheels and another Power Support Chain interlocking the lower level set of three Terminal Gear Wheels to remove concentration of force upon the said first Terminal Gear Wheel being exerted by the said Power Cable, and to serve as energy collection agent; A vertical Power Shaft, being a part of said Terminal Power Station, which holds and being driven by an upper level Power Gear and by a lower level Power Gear; A Power Chain, being a component of said Terminal Power Station, which interlocks the Power Gear attached to the Gear Shaft of the said upper level first Terminal gear Wheels with the Power Gear attached to the upper end of the said Power Shaft, and another Power Chain (the same kind and length as the first) interlocking the Power Gear attached to the Gear Shaft of the said lower level first Terminal Gear Wheel with the Power Gear attached to the lower end of the said Power Shaft, by which the said vertical Power Shaft is driven by the Terminal Gear Wheels, and by which the forward pace of the upper level Power Cable is controlled to become equal to the forward pace of the Power Cable at the lower level, so that the sail-mast will stay vertical at all times-not being affected by the small differences in circumference among the Terminal Gear Wheels it being that they have equal number of circumferencial notches or teeth; A Power Take-off Gear Wheel securely attached to the bottom tip of the said vertical Power Shaft; A Diagonal Brace String tautly tied to the bottom-outer corner of of the sail frame and connected to the top-inner corner of said frame to make the sail stay square against its own weight; A control string tied to the outer-top corner and another string tied to the outer-bottom corner of each sail that hold the sail stay rigid against the wind by tying its opposit end to the upper end of the succeeding sail-mast and the opposit end of the lower control string tied to the bottom end of the said succeeding sail-mast, holding the sail 45 degrees with the Power Cable; Said control string is provided with a Short-Hook String that is calibrated to snap-off to release the sail automatically during violent weather or when the wind speed becomes beyond the working limit, making the sail neutral to the wind to save the whole windmill from destruction; A Horizontal Arm Structure for each and every Terminal Gear Wheel, long enough to hold one said wheel away from the support post to provide clear passage of the large sails when they flip towards the said support post due to the wind direction, and strong enough to hold the said Terminal Gear Wheel in correct position against the high tension Power Cable pulling it outward; A Support-Post Structure for every pair of Horizontal Arm Structure (upper and lower level) to hold same high above the ground for a better wind contact, which can be in the form of wood poles or in the form of steel towers;
