What is claimed is: 1. A linear wind-powered electric generator installation, said installation comprising: at least two mutually spaced parallel extending closed-loop tracks; a supporting frame structure for maintaining said two tracks elevated above ground; said at least two closed-loop tracks supporting a plurality of vanes for linear movement along an essentially non-circular orbit in response to a streaming wind impinging against said vanes; and electrical power generating means being operatively associated with said vanes whereby said linear movement of said vanes generates an output of electrical energy. 2. An installation as claimed in claim 1, wherein said at least two closed-loop tracks are arranged in selectively vertical or horizontal orientations on said supporting frame structure. 3. An installation as claimed in claim 1, wherein said supporting frame structure is mounted on a turntable arrangement for imparting rotational yaw movement to said at least two closed-loop tracks. 4. An installation as claimed in claim 1, wherein each of said closed-loop tracks mount a plurality of said vanes independently of the vanes mounted on the other of said closed-loop tracks. 5. An installation as claimed in claim 4, wherein said vanes comprise blades having wing tip portions extending from a center which is mounted on said therewith operatively associated closed-loop track. 6. An installation as claimed in claim 1, wherein the plurality of vanes extends between and is operatively connected to said at least two closed-loop tracks. 7. An installation as claimed in claim 1, wherein said vanes are supported on said at least two closed-loop tracks by wing pylons. 8. An installation as claimed in claim 7, wherein said wing pylons are covered with wing pylon covers. 9. An installation as claimed in claim 7, wherein said vanes comprise wing-shaped blades having wing side plates. 10. An installation as claimed in claim 7, wherein said wing pylons include wheel bearing units, which are interconnected selectively mechanically, electrically or mechanically and electrically so as to maintain their positions fixed relative to each other. 11. An installation as claimed in claim 1, wherein said at least two closed-loop tracks comprise guide rails or guiding a wheel assembly connected to each of said vanes. 12. An installation as claimed in claim 11, wherein said wheel assembly comprises a pair of wheels including wheel bearings connected by a wheel axle fitted within said guide rails. 13. An installation as claimed in claim 1, wherein said electrical power generating means comprises, for each of said vanes, a permanent magnet and a rotor element, and for said tracks, a stator coil and core, so as to cooperatively generate power responsive to said linear movement on the vanes along said tracks. 14. An installation as claimed in claim 1, wherein said electrical power generating means comprises, for each of said vanes, a permanent magnet and a rotor element, and for said tracks, a stator coil and core, so as to cooperatively generate power responsive to said linear movement on the vanes along said tracks. 15. An installation as claimed in claim 1, wherein said at least two closed-loop tracks comprise both straight track sections and curved track sections, wherein said vanes are linearly movable along said straight track sections. 16. An installation as claimed in claim 3, wherein said supporting frame structure includes a weathervane for enabling controller means to impart a yaw movement to said at least two closed-loop tracks so as to optimize the effect of streaming wind impacting said vanes in dependence upon the direction of the wind. 17. An installation as claimed in claim 1, wherein there are provided at least three of said closed-loop tracks in parallel spaced relationships with each other, and a plurality of said vanes being connected for linear movement between each of said at least three tracks. 18. An installation as claimed in claim 6, wherein said at least two closed-loop tracks mount further vanes extending outwardly from opposite sides of said tracks. 19. An installation as claimed in claim 17, wherein said further vanes are cantilevered radially outwardly of said tracks substantially coaxially with the plurality of vanes extending between said at least two tracks. 20. An installation as claimed in claim 1, wherein said vanes each possess an essentially airfoil shape in transverse cross-section in conformance with specified dimensions required by said installation. 21. An installation as claimed in claim 1, wherein said orbit is essentially oval. 22. An installation as claimed in claim 20, wherein said oval orbit has straight essentially parallel side sections and convexly rounded end sections connecting with said side sections. 23. An installation as claimed in claim 21, wherein said oval orbit has straight side sections widening towards the upper end thereof, including a large upper convexly rounded end section and a narrower lower convexly rounded end section. 24. An installation as claimed in claim 22, wherein said upwardly widening oval orbit is formed by a further closed-loop track extending with the oval track having straight parallel sides, said tracks being equipped with vanes having adjustable spans and fixed wheels or vanes having foldable outrigger portions with sliding wheels, movable from outside of said oval tracks. 25. An installation as claimed in claim 20, wherein said oval orbit is inclined forwardly within the plane of said at least two tracks. 26. An installation as claimed in claim 20, wherein said oval orbit is inclined rearwardly within the plane of said at least two tracks. 27. An installation as claimed in claim 1, wherein said supporting frame structure supports said tracks from the outsides thereof, and the vanes move within the tracks. 28. An installation as claimed in claim 1, wherein said supporting frame structure supports said tracks from the interior thereof, and the vanes move externally of the tracks. 29. An installation as claimed in claim 1, wherein said supporting frame structure supports said tracks from the outside and interiorly thereof, and said vanes move both externally and interiorly of the orbit defined by said at least two tracks. 30. An installation as claimed in claim 1, wherein said orbit defined by said at least two closed-loop tracks is essentially trapezoidal. 31.
