TECHNICAL FIELD OF THE INVENTION This invention is in the domain of mechanics, and is related to propulsion mechanisms, which utilize the energy of the wind and/or sun to generate mechanical energy. According to the International Classification of Patents (MKP) an invention can be marked with the classification symbol F03D3/00, which includes classified wind propulsion mechanisms with a normal axis of rotation to the wind flow w entering the rotor, or with the somewhat closer symbol F03D3/04, in case of a stationary instrumentality for wind direction with channels. Since this is an invention which also utilizes the energy of the Sun in order to generate mechanical energy, it can be marked with the classification symbols F03G6/00, or F24J2/00.

An invention can also be marked with the classifying symbol E04D13/18, which classifies all roof covers with devices that collect energy.

In this manner, invention can also be marked with classifying symbol F24J2/04, intended for solar heat collectors, which conduct working fluid through the collector or with the symbol F24J2/05, if they are surrounded with a transparent fence. TECHNICAL PROBLEM

A problem which this invention addresses is as follows: how to handle the construction of the solar windmill which uses solar energy and/or wind energy in order to spin electric generator, in order to generate an electric current, accomplished by using the following parts: collector, chimney (containing wind turbine rotor and a generator), while a special device called a "cap" is placed on top of the chimney.

The second problem solved with this patent is introducing a transportation system for people and goods, for remote areas which don't have roads, such as mountain tops, islands etc. That can be accomplished thanks to the possibility of removing that cap from solar windmill, and moving around like an aircraft, powered by energy from batteries, produced by the solar windmill itself. The chimney of solar windmill, can also have multiple purposes, it can be used as pillar for various energy cables, telecommunication cables, transportation cable cars, etc. This is possible due to a fact that the rotor is not outside like as is the case with classic windmills, or the space beneath the cap of the solar windmill is free and can be used for various other purposes. As most of the solar windmill's weight is very low because the rotor-generator is set on the ground level, the height that the solar windmill can achieve is substantial. BACKGRAUND ART

Permanent windmills actually use only the horizontal component of wind. Wind speed as a particular source of energy affects the windmill in compliance with location and annual average wind speed. Average wind speed is in relation with height above the active flat surface of the ground. Energy of the wind that can be used substantially increases when height surpasses 1000 m from active surface.

For energy conversion, the rotor of the windmill can have horizontal or vertical axes of rotation, with blades which are moving in circular areas.

There is a well known type windmill where the rotor and the generator are placed on top of the pylon and can be aligned with the wind for maximum efficiency.

Those kinds of machines can't use thermal streaming of air, which is formed due to the soil heating up with solar energy.

Devices that can use this kind of air movement are known as solar towers, or as solar chimneys. A project involving a solar chimney was tested in Madrid in Spain, and it was considered a success. Those solar chimneys are widely known as chimneys with up draft or down draft air intake.

So far it is not known if there exists any device that combines the work of the windmill with a solar chimney in such a manner that uses all the air streaming and winds, unlike solar chimneys or classic windmills, with the position of the propeller and generator on the ground level of the windmills pylon with the lowest as possible centre of weight.

A large number of windmills can be found in all patent files, but in this document we will list only a few of them for demonstration, because they only share the domain with this new invention.

In the patent file with the mark YU 47541 which bears the name "Propeller windmill with an object made of reinforced concrete and with a steel tower for routing the air flow", a solution is offered for the problem to constructing a windmill able to be driven by artificial wind, which is made from Sun's energy, converting the temperature difference in the form of artificial wind to useful mechanical power, where solar heating cells are embedded in the construction.

In the patent file with the mark YU 47708 a wind turbine is described with several rotors and a telescopic part drawn in to each other, and an impellent wheal is built in the base part of the turbine.

One vertical turbine with a stabilized central air router, which is consists of a larger number of symmetrical wings, where an air router located in centre of the roatary wheel of the turbine, which is spin around its axes for the purpos of detecting air flow direction, is described in the patent file with the mark RS 52649. In the German patent file with the mark DE Ai 3801671 a wind turbine is described which consists of a vertically placed cylindrical cage rotor, with stable ball-wings, placed around it on base floor in shape of a ring which can be rotated around their vertical axes and where its angle of rotation can be hydraulically preset.

One vertical turbine, described in the American patent file with label US 4,245,958, is placed in a skeleton which has four vertical pylons interconnected with plenty of tumblers, connectors and fasteners. Examination of all other patent documentation with a coresponding classyfuing symbol did not provide a solution for the solar windmill, which might correlate with the solution represented by the invention described in patent application. DISCLOSURE OF THE INVENTION

The basic idea for the construction of the solar windmill according to this invention is to use energy of the wind and/or solar energy for the production of electrical energy.

Construction of the solar the windmill consists of: collector, chimney (together with the rotor of the windmill and the electric generator) and cap.

The collector consists of an upper central glass part, and a lower peripheral transparent plastic part.

The upper part of the collector consists of sectors, with all of them grouped together forming a cylinder, with an upper end that forms a shell in the shape of a truncated cup. The inner cylindrical opening, with a diameter equal to the outside diameter of the chimney, is formed in the centre of the upper part and passes through the entire height of the upper part. The lower peripheral part of the collector is also made of plastic sectors, whereby in construction the number of segments (sectors) of upper and lower parts is equal. Sectors of the lower part, when aligned, all together form a cylinder, which ends in the shape of a parted shell of truncated square pyramid. The inner cylindrical hole of the cylinder has a diameter equal to the outside diameter of the upper glass part, and it is situated in the centre, and surpasses the height of the lower part.

The rotor and the blades of this wind turbine are made of at least six or more cylindrical parts, which are placed on curved segmental tracks, where each cylindrical part from below has a circular toothed arched lath, which transmits the rotational movement of the rotor to upper pair of conical gears, positioned below the rotor. From the upper pair of conical gears through the vertical shaft, rotation is transmitted to the lower pair of conical gears, which then move the horizontal shaft of generator which in that case produces electric energy. The generator is placed in the space below the rotor.

The narrow part of the chimney can be made of one single pipe, or, like a telescope, with several extensions. The lower cylindrical part of the chimney transitions to the middle conical part, and after that, to upper cylindrical part. Within the lower cylindrical part of the chimney, the rotor is partly placed.

The cap has an outer and an inner layer, or, it is double - layered. The outer layer is transparent with an impressed pattern with, or without, tiny holes, and the inner layer of the cap is made with thermo accumulating properties. The aerodynamic shape of the cap, which has openings placed downwind, in correlation with the outer layer which has tiny holes, creates zones of low air pressure, and that is how the cap increases suction capacity (draft) of the chimney. Between the outer and the inner layer of the cap, spacers keep distance of the space between those layers, and sensors of air pressure are also added. The cap is made with additional openings for air release from the space between inner and outer layers, and with air wings which hold the direction of cap in accordance with wind flow direction. In the cap body, under the thermo accumulating layer, there are helium balloons inflated on the atmospheric, or very small pressure, and in the cabin there is an electric motor which drives the compressor, and batteries to give power to the motor, and high pressure helium tanks. Helium balloons are filled and emptied with helium from high pressure helium tanks by the compressor. The cap is placed on the chimney on a particular axial ring bearing, and it can rotate around the chimney axis in order to take the direction of the blowing of the wind. When the direction of the cap is downwind, and air is streaming along the cap body, and create certain zones of low air pressure, which are channelled to the chimney exit point, and this increases chimney suction power (draft). If we increase chimney suction power, we can increase the power of the wind generator installed in the chimney, and, correspondingly the power of the electric generator as well. The solar windmill according to this invention has four working stages, or working regimes, and those are: with wind as the energy source, with Sun as the energy source, simultaneous use of wind and Sun energy, and the pump working regime (or subsidiary working regime). The solar windmill most often operates in the combined mode (regime of work), using both types of energies (wind and Solar), while sensors for air flow and pressure regulate the opening level of electromagnetic butterfly valves (doors) in the collector, while also, the roof planes can be adjusted according to direction of wind flow.

When we talk about solar windmills with telescopic extensions, it is possible to accomplish a work mode (regime of work) similar to a pump, otherwise, if there are no extensions then this mode is impossible.

When the solar windmill is working in the pumping regime, it is necessary to accomplish movement of the cap, which stands on the chimney telescopic extension, between the lowest cap position and the highest cap position. The raising of cap is accomplished due to helium balloons in the cap, so when they are inflated, they tend to carry telescopic extensions along with the cap, all the way to the highest cap position. While the cap is moving up to the higher position, air flows up the chimney, and also moves the rotor to make useful work, and after that the air passes through the chimney and the cap and then is released outside. While the cap is moving down to a lower position, compressor compress the helium from helium balloons back to the high pressure tanks, and due to the increase of the weight of the cap, it tends to go down while compressing the air in the chimney which in the lower part of the chimney tends to flow in the opposite direction, or toward the ground. That air flow in the lower part is redirected to angled tubes, and going to the rotor intake, and in such a peculiar way, when the butterfly valves are closed in that time frame, so the air must flow through the rotor and do the useful work, and after that through underground pipes to the lower peripheral part of collector. In that part the air is heated once more due to latent heat from walls and thermo accumulator slopes, and in the underground pipes, and then is moving up, while the cycle of the cap movement is repeated between the lower and the upper position, until latent stored heat exists in the collector.

If on any height which the cap can reach with telescopic extensions, there is enough air or/and solar energy, then the solar windmill will work in that regime with the existing energy, and the subsidiary regime of work as a pump ends.

DETAIL DESCRIPTION OF THE INVENTION

Solar wind turbine consists of a collector 1, a chimney 2 (in which the wind turbine rotor 27 and the electric generator 32 are located), and a cap 3. Collector 1 is consisted of upper central glass part 4 and a lower peripheral transparent plastic part 5.

The lower part 5 of the collector 1 consists of at least four plastic sectors 19, with the same number of sectors 19 of the upper 4 and lower part 5 of the construction. Sectors 19 of the lower part 5 put together form a cylinder (not numbered in the blueprint drawings) which ends in the form of partial shell of a truncated square pyramid (not numbered in the blueprint drawings). Every sector 19 of the lower part 5 has a transparent plastic roof planes 20 made of PVC, Lexane, or Graphene, with the reinforcement along the edges, while the roof planes 20 can be partially rotated around μ, η, ξ axes, and can be lifted with the cable system 23. Roof planes 20 are supported with partition walls 21, which have their own fundament 22, and with thermo accumulation slopes 7, form sectors 19 which, all together aligned in circle, form a collector lower part 5. Sectors 19 in the drawings are denoted by the cardinal points, namely, by the initials of the cardinal and intermediate directions in the collectors with eight sectors: 19N, 19NI, 191, 19SI, 19S, 19SW, 19W, 19NW. Walls 21 and slopes 7 accumulate the sun's heat, and then emit it at night or at a sudden drop in temperature.

Electric generator 32 is located in the space 10 which is under the rotor 27. Underneath the lower part of the chimney 2, the cyllindrical area 9 continues, in which the elevator (not numbered in the blueprint drawings) is optionally placed. Valve 8 is also located in the area 9, and it can take two positions, first (I) in the upper, and second (II) in the lower part of the area 9. Area 9 is connected to every segment of sector 19 of the lower part 5 of the collector 1 by underground pipes 6. In the centre of the lower part 5, the inner cilindrical openning is located (not numbered in the drawings), that goes all the way through the collectors lower part 5, which contains the glass part 4, with spiral walls 18, as the extensions of sectors 19. The upper part 4 of the collector 1 consists of at least four or more sectors (not numbered in the drawings) in continuation from the sector 19, that are all together aligned to form the cylinder (not numbered in the drawings) . The upper side of the cylinder forms a shell shaped as truncated cone (not numbered in the drawings), with inner cylindrical opening (not numbered in the drawings), in the centre of the upper part 4, of the collector 1, and passes through entire height of the upper part, with same diameter as wider part 26, of the chimney 2. Steel construction of the upper part 4, is formed with at least four steel pylons 11 with their own fundaments 12, where each spiral intake (not numbered in the blueprint drawings), has one pylon 11. The spiral walls 18, start from the pylons 11, and spread in a form of the spiral all the way to the centre, to the chimney wider part 26, which has rotor in side, while the space between the spiral walls 18 creates the spiral intake. Sloped bearings 13 are mounted on pylons 11, which support the bearing ring 14 and the bearing ring 14 holds the chimney 2, so in that way pylons 11 bear the chimney 2.

Special profiles 15 are also mounted on pylons 11, which bear glass plates (not numbered in the blueprint drawings), to form outer transparent shell, of the collector 1 upper glass part 4. Spiral intakes, (not numbered in the drawings), bordered with spiral walls 18 which have thermo accumulating properties, represent spiral channels which are used to swirl the stream of air on the entrance of the rotor 27 of wind turbine.

In every spiral intake (not numbered in the drawings), a solenoid valve 16 is placed, which may be constructed in form of the butterfly. Alongside of every solenoid valve 16, in a space between the spiral walls 18, - or let say in spiral intake, the sensors 17 for air flow and pressure are placed to measure characteristics of air flow by means of which the inclination angle of the solenoid valves 16 is regulated. Collector 1, collects the wind from direction w, and direct air stream towards the rotor 27, and the chimney 2, but at the same time allows for sun rays to pass through them to the slopes 7, when the slopes 7 gets hot, the heat is transmitted to the air by means of convection, and the air than starts its movement to the wind turbine rotor 27 and the chimney 2.

Wind turbine rotor 27, is made of arched segments with blades 37, at least six of them (usually 6, 8, 10 or 12), placed on arched segmented tracks 36, with bearings, where each of the arched segment 37, from the bottom side has attached a toothed arched lath 35, which transmit rotational motion of the rotor 27, to the upper pair of conical gears (not numbered in the blueprint drawings), which are placed beneath the rotor 27. From the upper pair of conical gears (not numbered in the blueprint drawings), by means of vertical shaft, the motion is transferred to the lower pair of conical gears which transfer motion to the horizontal shaft (not numbered in the blueprint drawings), and that all together in this text has one integral name: Mechanism of rotational transmission 31, which is connected to the electric generator 32 and thus produces electric energy. Wind turbine rotor 27, together with electric generator 32, are consisting parts of the chimney 2.

The chimney 2 can be produced either as one long pipe, or with telescopic extensions 33 and 34, which are extended to the upper cylindrical part 24. Lower cylindrical part 26, of the chimney 2, is connected to the upper cylindrical part 24 through conical part 25. In side of the lower cylindrical part 26, of the chimney 2 a rotor 27 is partially placed (with vertical axes of rotation), where the inside diameter of the rotor 27 is almost equal to the outer diameter of the upper cylindrical part 24, of the chimney 2, and outer diameter of the rotor 27 is almost equal to the inner diameter of the lower cylindrical part 26, of the chimney 2.

Just above conical part 25, of the chimney 2, the angled pipes 28, are installed which connect the chimney 2 with spiral intake (not numbered in the blueprint drawings). On the entrance of every angled pipe 28 from chimney 2 one solenoid valve 30 is installed, and on the bottom side entrance in the upper cylindrical part 24, of the chimney 2, one valve 29 is installed. On the exit from top side of the upper cylindrical part 24, or on one of the extensions 33 and 34, of the chimney 2, on the cabin 46, one valve 42 is installed. On the top of the upper cylindrical part 24 or on one of the extensions 33 or 34, of the chimney 2, the cap 3 is placed, which can rotate on the top of the chimney 2 according to the wind direction w. In that way the exit of the chimney 2 gets more suction power, because the cap 3, create the zone of pressure reduction due to the air streaming around its surface, and this reduction of the pressure is transferred to the top of the chimney 2 and that's how cap increases the power of the chimney, and the power of electric generator 32 as well.

Cap 3 has transparent outer layer 38 or/and 39, and inner layer 41, which has thermo accumulating properties. The first outer layer 38 is made of transparent materials with imprinted pattern with tiny holes 45, while the second outer layer 39 is made of transparent materials with imprinted pattern without tiny holes. Tiny holes 45 are made in order to enable exit of the air from the air gap 40 out of the first outher layer 38. In that way the first outer layer 38 with imprinted pattern with tiny holes 45 creates a zone of air whirling and low pressure, and hence increases the suction power (draft) in the cap 3 and the chimney 2. The inner layer 41 is made as an shell with thermo accumulating properties. Between outer layers 38 and/or 39 and inner layer 41, in the air gap 40 with air some pressure sensors are installed. The cap 3 is constructed with additional aerodynamic openings 43 on leeward side, for rapid air release from the air gap 40, and with flaps 44 to maintain direction of the cap according to wind direction w.

The cap 3, must have aerodynamic shape, very light, that can be easily redirected toward the direction of the wind w, which is accomplished with the use of an rotating electromagnetic axial bearing 54, which can hold the cap 3, attached to the chimney 2, and allows that the cap to swivel freely around longitudinal axis of the chimney 2. The cap 3, is pulled near the electromagnetic axial bearing 54, with electromagnetic forces and then locked in place mechanically, in the way that is able to rotate around longitudinal axes of the chimney. Direction of the cap 3, towards the wind, is accomplished with flaps 44, and with non-equal distances between front and rear end of the cap 3 in favour to rear end, from longitudinal axes of the chimney 2. The inner space of the cap 3 must be spacious for accommodation of all Helium balloons 48 under the atmospheric pressure or small pressure of around 0.1 till to 0.5 MPa, while the cabin 46, must have enough space for the Helium bottles 53, under very big pressure of up to 500 Mpa, and room for the compressor 50, which is driven by the electric motor 51, powered by electric batteries 52. The cap 3, which has all above mentioned properties, is similar to an air ship which uses Helium to inflate the balloons 48 from high pressure bottles 53, and compressor 50, is used to compress Helium from the balloons 48 back to the high pressure bottles 53, and hence altering the caps altitude as needed. If the cap 3, is separated from the chimney 2, by releasing from the electromagnetic axial bearing 54, it can be moved around freely through the space as an air ship which has rudder with electromotor fans 55, for propulsion, powered by the batteries 52, and land anywhere, on its own wheels 56. The suction pipe 49, that passes through the cabin 46, and is its consisting part, has identical diameter as higher telescopic extension 34, and connects the chimney 2 outlet with air gap 40. The way that cap 3 operate is that the air stream from the chimney 2, through the suction pipe 49, which is in the cabin 46, right to the air gap 40, between the outher layer 38 and/or 39 and thermo accumulating inner layer 41, which are separated with spacers 47, only to be released in the atmosphere through the cap 3, or via tiny holes 45 on first outer layer 38, as shown on figure 10. The air from the air gap 40, can also exit out through additional openings 43, placed on leeward side, to help the air transition from the air gap 40, of the cap 3, as shown on figure 3. The air gets out of the air gap 40, sucked by low pressure around cap 3, which is present due to wind rapids flow over and around the cap 3, as an aerodynamic obstacle, but also because of the first outer layer 38 with tiny holes 45, which is creating additional pressure drop on its surface. So in a fact, that low pressure area, marked on the pictures with , formed by the wind flow around the cap 3, has role of a vacuum pump, vacuum is then transferred to the outlet of the chimneys upper cylindrical part 24, or to its extensions 33 and 34. In that way cap 3, makes additional suction to the place of connection with the chimney, and hence has amplifying effect to the chimneys power.

Solar windmill, according to this invention has several operation modes, or to be more precise has four working regimes: propulsion by the energy of the wind, propulsion by the energy of the Sun, propulsion with the energy of the wind and the Sun, and at last a pump regime.

Solar windmill, powered on wind energy, collect the air flow close to the ground with part of collector 1 that is open to receive the wind w, with sectors 19, of the collector 1, which are at the windy side (or facing the wind). As the transparent roof planes 20, of the sectors 19 are semi swivelled around its edge axes (μ, η, ξ), so they can accept additional air from the wind flow and redirect it toward the centre of the collector 1, or the outlet of sector 19, toward the inlet of spiral intake (not numbered in the blueprint drawings), in other words through the space between spiral walls 18, toward the chimney 2. As the space between partition walls 21 gets more and more narrow approaching the centre, and this reduction continues through spiral intake between spiral walls 18, looking at the chimney direction, so it is obvious that increased air pressure will acquire +++++++, in the collectors part 1. The air that is stuck in on entrance of the chimney 2, first must pass through the wind turbine rotor 27, to spin that rotor 27 and then to enter in to the chimney 2 in form of a swirl. Wind that flows around cap 3, creates the zone of increased air pressure ++++++++ (around the outher layer 39 with pattern without tiny holes) and the zone of decreased air pressure

(around the first outher layer 38 with pattern with tiny holes 45). That is how the air is propelled through the chimney from the zone with increased air pressure ++++++++ in collectors 1 surrounding area that is on the base level, up to zone of lowered air pressure around cap 3, and that has an significant impact on nominal power of chimney 2. With the use of collector 1, and the cap 3, more an updraft through the chimney 2, can be achieved, the power of chimney is increased, which is then manifested on the wind turbine rotor 27, which will tend to increase its rotation per minute (rpm), and finally it is manifested on the electric generator 32 as an increase of electric power. In the part of the collector 1 that is on the leeward side, or the opposite side of wind direction w (with sectors 19 which are in leeward side of the collector 1) the solenoid valves 16, in their corresponding spiral intakes (not numbered in the blueprint drawings) are semi opened, or even closed and preferably automatically regulated. Collector 1 is centrally symmetric and constructed in the way that the sectors 19 which are in the wind can be additionally opened according to the wind direction w - or on windy side, and the other side rotated for 180 ^° away from the first, or leeward side is then out of the function, and does not have any effect on rotor 27, and if it is more appropriate it can be completely shut down with solenoid valves 16. Windy side or leeward side are in the correlation with wind direction, but as all of the sectors 19 of the collector 1, are identical, then all of them are able to catch the wind regardless of the wind direction. Solar windmill, with propulsion on the Sun energy only, works in a way that collector

1 allows Sunrays to pass through transparent roof planes 20, to thermo accumulating slopes 7, and with constant heating of this slopes 7, the heat transfers to the air by convection, which is moved toward rotor 27, because it has been pushed by the colder and more dense air outside of the collector 1, almost radially through the collector 1, toward centre, and chimney 2. So collector 1 accepts and directs the air flow almost on the same way towards rotor 27 regardless of the cause of the air movement, whether is the wind or the Sun, only in the second case all solenoid valves 16 are completely opened, because the similar air pressure is expected in all sectors 19, of the lower part 5, of the collector 1, if the Sun rays inclination angle isn't too big, or if it is close to vertical like on equator, or with in the summer mounts in the North geographic regions, on that latitude. On the exit of the chimney 2, cap 3 is placed, and its side exposed to the Sun rays cap 3 passes through the Sun rays, which further pass through transparent outher layers 38 and/or 39 and fall to the thermo accumulating inner layer 41, which transmits that energy to the surrounding air in air gap 40 and increase its potency to leave the cap 3, through additional openings 43 on the top, or on the back end of the cap 3, as well as on tiny holes 45, of the first outer layer 38, so again in this way cap 3 is used as an amplifier for the air stream out of the chimney 2. Solar windmill most often works in the combined regime, powered from both energy sources (wind and the Sun energy source), where sensors 17 for air flow and pressure feeds the central processing unit (not numbered in the blueprint drawings), with the data, which then regulate the level of inclination of the solenoid valves 16, while regulation of the roof planes 20 inclination angle, according the wind speed and direction, as well is being regulated with the same central processing unit (not numbered in the drawings) which are positioned somewhere within the collector 1, of the solar windmill.

When the solar windmill work as a pump, it is necessary to obtain the movement of the cap 3, positioned on the chimney 2 with telescopic extensions 33 and 34, between two positions: lower and higher. Raising the cap to the higher position is accomplished via Helium balloons 48, which are filed from pressure bottles 53 with Helium under vast pressure. The cap 3, with the balloons 48 filed with Helium is than moving up, carrying with it the extensions 33 and/or 34, or more of them if there's more of them and with all of them gets to upper position. In this regime of work (like a pump), the valve 42, is shut all the time.

When the cap 3, moves to upper position, solenoid valves 16 and end valve 29 are opened, and solenoid valves 30 (minimum four of them or more), on angled pipes 28, are closed as well as valve 8, which then stands in upper position (8-1), so the air from sectors 19, flows up towards the rotor 27, moves wind turbine rotor 27 and does useful work, and then that air passes through chimney 2.

When the cap 3 is moving to lower position, compressor 50 compress Helium from balloons 48 with Helium, back to the bottles 53 under high pressure, while solenoid valves 16 and valve 29 are closed, while solenoid valves 30 (minimum four or more) are opened, on angled pipes 28, and the valve 8, which than takes lower position (8-11), so the air can flow through free space for the elevator 9, and then through underground pipes 6 and enters the lower part 5, of the collector 1. In that part, the air is heated once more because of the stored heat in thermo accumulating slopes 7 and walls 21, and in pipes 6, and then moves up again, while cycle is repeating all over again between this two positions of the cap 3, until stored heat is completely used.

If on some height of the chimney 2, which is reached with its extensions 33 and 34, and the cap 3, exists enough energy of wind or/and of the Sun, then working regime of the solar windmill will accommodate that dominant energy source, and pumping regime will then be stopped.

The cap 3, is constructed as double layered, that is, it has two shells, where air flow from the chimney 2, after passing suction pipe 49, enters in side of the air gap 40 which is the space between this outher layers 38 and/or 39, and inner layer 41, where first outer layer 38 is transparent with the pattern with tiny holes 45, and second outer layer 39 with pattern without tiny holes, and inner layer 41 has thermo accumulating properties. The air from the air gap 40, between the outher layers 38 and/or 39 and the inner layer 41, is released out by the suction of low pressure , through tiny holes 45, of the first outher layer 38 and additional openings 43. Lowered pressure , around the cap 3, is transferred to the outlet of the chimney 2, in order to increase the suction power of the chimney 2 (adding more draft to it).

Draft (suction power) is in the function of the temperature, and rise linearly with height of the chimney 2, and flow of the gasses rise according to square root from the height of the chimney 2 (height above one that is necessary to obtain in order to overcome the resistance of the corresponding plant). Besides that, amount of produced energy will correlate with surface area covered by the collector 1, its shape, and of the way it is adapted to the local ground where it stands on, as well as, of the ability of the roof planes 20 to swivel according to wind blow and collect even more wind. Beside the collector 1 pulling power of the solar windmill will correlate with size and volume of the cap 3, from its ability to swivel according to the wind direction, its aerodynamic profile, of the outer transparent layers 38 and 39, and many other characteristics.

With this construction, made this way, the inventors basic idea to use the Suns or/and the winds energy in order to obtain the electric energy, is accomplished. INDUSTRIAL AND OTHER USES OF THE PATENT

This invention belongs to the energetic domain and especially to production of electric energy from renewable sources, from wind and the solar energy, transformed to thermal movement of the air which propels production of electrical energy, and this is the basic purpose for the solar windmills. Places where installation of those devices will bring biggest contribution are mountain tops and gorges, cliffs and coastal areas, islands, places where a lot of wind is expected for propulsion of wind-generator, but also all other places with extensive solar radiation or with a large number of sunny days like tropical areas, savannahs or desert areas are eligible.

The chimney of the solar windmill (or more of them together) may serve as support (bearing pillar-because there is no rotor outside to interfere) for different transportation systems, for example a cable car, where they can be propelled by electricity produced on the spot, and then used to power different electric motors of this transporters apropos cable cars. Besides that when the cap is separated from rest of construction, it can be used as specific airship and fly around like any other dirigible, and in that case this invention is used for transportation purposes with its own source of energy for propulsion. With more of the solar windmills in the system distributed throughout an area with caps like this, it could even be assigned a permanent timetable. As a solar windmill is foreseen to stand by itself on mountains, hill tops, or islands then it is obvious that even most remote and isolated villages or other settlements, where bringing electric power to them is not economically viable, due to losses caused from the long distances. With this invention every distant mountain or island village will have its own electric energy produced on that spot, which will fulfil their daily needs for energy or for transportation. Without that, but also even because of the permanent increase of electrical energy, partially because of the shortage of the fossil fuels, transport of electrical energy to these distant places isn't economically viable, and because of that these places will suffer a lack of electric energy for their needs and development. On the other hand, those rural and unpolluted places are now more in focus, because of the healthy food that can be produced there in conditions of high altitude and isolation, plant diseases do not exist, so pesticides aren't in use, therefore it is possible to produce organic food, or matical plantations, which is not possible for the lowland and a big scale modern agriculture. If with cable cars and dirigible-caps, we can achieve more rapid communication with capital cities, or at least with main roads and highways, then life in mountain villages will become sustainable again, and settling abandoned villages will start again. Besides transportation of electrical energy, goods and people, with system of cable cars or/with caps - dirigibles, it would be possible to transport even water to remote places, and in case of forest fire incidents, special caps- dirigible can be used to extinguish forest fires from their flying height. Transportation system dirigible-cap and/or cable car together, and in symbiosis with solar windmill which energises them with electric energy, should ease communication and transport during winter months, when all other means of communication are blocked due to snowfall and snowdrift, but also as one additional alternative, and in the same time the shortest direction for people and goods from the base of the mountain to its top, or from one solar windmill to another solar windmill in form of a straight line, despite of roads which have curves and serpentines. Even the solar windmill itself would be some kind of a tourist attraction, which has touristic potential, and can be used as watchtower with a nice sight, or as a mountain residence or as a watchtower for foresters, for the forests' conservation etc. And if we add technical detail that is typical for solar windmills with telescopic extensions, that the cap can be erected up to the significant heights of 1000-2000m (and even more) and when we add mountain height then we can draw the conclusion what touristic potential one such construction might have. And that further means that in the pedestal of such an object, we could incorporate all kind of Mountain homes, forester homes, commercial objects like hotels, or ski resorts, or even spa centres, and for sure for all these resorts the electrical energy would be made on spot, and surplus of electrical energy would be directed to distant villages, or at the end, to the electric distribution system... Ultimately the cap itself, which is a special kind of dirigible which can be separated from the rest of the system, while the rest of the system can operate with reduced power, provides new possibilities of economic exploitation for touristic purposes, as well as for transportation purposes, or for monitoring, fighting against forest fires, for the evacuation of people due some disasters, and for many other situations and purposes.
