Claims

1. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators characterized in that the arrangement consists of a horizontal tubular metal shaft supported in its middle by a vertical, slowly rotating shaft so as to have the capacity to rotate horizontally; at its two ends it is supported by two vertical tubular metal columns (fig. 1) which follow the horizontal rotary motion of the
horizontal shaft, as the latter changes direction, rolling on circular iron rails by means of wheels (fig. 5) . The horizontal shaft bears on either side of the support point, located in its middle, two fans each consisting of four flat frames/blades fixed along the shaft at an angle of 90° between each other (fig. 2) .
The ends of the horizontal shaft are supplied with wheels (fig. 13) which by means of belts convey the rotary motion of the horizontal shaft to the generator shaft; they are designed to follow the rotary circular motion of the horizontal shaft. The whole system seats on a reinforced concrete base at the perimeter of which there is an inclined surface some meters higher than the horizontal shaft (fig. 15), which surface is almost seated on the ground. The inclined surface is destined to offer protection from the wind to the lower half of the frames and to enhance the wind before driving it towards the upper half of the frames on the horizontal shaft (fig. 15, 16) . The inclined surface, covered with nylon or thin aluminium sheets, performs a rotary path of 360° on the iron rails following the course of the horizontal rotating shaft. On either side of the inclined surface there are two divergent vertical windscreens covered with nylon or thin aluminium sheets. The height of the windscreens is equal or greater than that of two fans whereas its length is variable. A section of each windscreen, actually the one by the worksite, is rotary and follows the course of 360° performed by the inclined surface ; the other section of the windscreen is immobile and has a North-Northeast direction. The horizontal shaft is furnished with 1-4 wheels located on either side thereof which wheels are connected to respective
generators.

2. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claim 1 characterized in that (fig. 2) along the horizontal shaft there are two fans consisting of flat, metallic frames/blades made of worked iron for more secure support. Each row of the flat frames is divided into six to eight sections, three or four of which are positioned on the left of the seating point of the horizontal shaft onto the vertical shaft whereas the other three or four are positioned on the right thereof. The base of each row of the flat frames, attached to the horizontal shaft and firmly fixed thereon, is placed at a distance of 90° between each other. These blades are covered in their half, at the side facing the periphery, with nylon or aluminium sheets whereas the other half thereof located by the shaft remains uncovered (fig. 17) .

3. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claim 1 characterized in that the system (fig. 1) serving for the support of the horizontal shaft in its middle consists of an iron base of 1.5-2.5 X 1.5-2.5 m and 3 cm thick (fig. 3), an external, tubular, iron casing firmly fixed by its base on the iron base of 1.5-2.5 m, and an internal, slowly rotating, tubular iron shaft on the top of which the horizontal shaft is
mounted. This internal rotating tubular shaft is housed in the external casing and seats by its sealed base on three grooved rows filled with big ball-bearing balls and grease (fig. 4) .

4. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claim 1 characterized in that the two iron columns used to hold the horizontal rotating shaft by its ends are not fixed on the ground but are seated and move slowly by means of four wheels located at the base of each iron column on two circular iron rails by 360°.

5. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claim 1 characterized in that either side of the two ends of the horizontal rotating shaft is furnished with 1-4 wheels each connected to the shaft of respective generators firmly fastened on a low, open, small car moving slowly on four wheels of slightly arch-like form on iron rails by 360° depending on the
direction followed by the horizontal shaft (fig. 2, 5) .

6. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claims 1 and 3 characterized in that the four rows of frames are fastened to the horizontal shaft by means of three separate arrangements (fig. 8, 9, 10, 11, 12) .

7. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claim 1 characterized in that it is supplied with an inclined, rotating surface on the perimeter of some more meters higher than the horizontal rotating shaft whereas its metallic base is almost seated on the ground (fig. 15, 16) .

8. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claims 1 and 7 characterized in that (fig. 15 and 16) the base of the inclined surface is almost seated on the ground whereas its top is somewhat higher than the horizontal shaft (fig. 16) . The entire surface of the inclined rotating surface is covered with nylon or aluminium sheets .

9. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claim 1 is characterized in that (fig. 15, 16) two vertical windscreens are positioned outside the worksite at the periphery. A section thereof is rotary and seated on the outer divergent side of the inclined surface whereas the other section is firmly fixed on the ground with its open and large side having a North-Northeast direction. The said windscreens can be made either of iron or from mixtures of substances showing greater resistance and small special gravity.

The same stands for all iron constructions of the present invention (fig. 2) . Their length is variable whereas their height is 1 to 2 m greater than that of two blades. The surface of the windscreens is covered with nylon or thin aluminium sheets (fig. 15,16).

10. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claims 1 and 2 characterized in that the horizontal shaft, the inclined surface, and the two windscreens can be immobile and not vertically rotating (fig. 2) .

11. Method for engaging aeolian energy and transformation thereof into electric energy by means of generators in accordance with claims 1 and 2 characterized in that half of the surface of the frames/blades may be covered, preferably the section towards the periphery, whereas the rest of it located by the shaft remains uncovered. The outer sections thereof are slightly folded in (fig. 17) .
