BACKGROUND AND THE STATE OF THE ART Wind power is considered one of the cleanest energy sources presently available, and wind turbines have gained increased attention in this regard.

The wind turbine industry is growing at an incredible rate.

Global Wind Energy Market is projected to surpass USD 170 billion by 2024, as reported in the latest study by Global Market Insights, Inc.

The U.S. Department of Energy has an initiative to further increase wind energy's contribution to 20% of the U.S. electricity supply by 2030.

To meet this demand, there is a strong need for innovative wind turbines to be developed.

A modern wind turbine typically includes a tower, a nacelle mounted atop the tower, a generator, a gearbox, and a rotor including one or more rotor blades. Most of the wind power in the world today is produced by the most common large three-bladed horizontal-axis wind turbines. These turbines have the main rotor shaft and electrical generator at the top of a tower.

Some of the more advanced large wind turbines are variable-speed wind turbines, such turbines allow the generator/rotor speed to differ according to wind speed between cut-in and rated speed. Above rated speed, the generator/rotor speed is then held constant. Variable-speed wind turbines will on average produce 10% more electricity.

At very high rotor speeds and low wind speeds, the power has turned negative.

Therefore, and to avoid crashing of blades, wind turbines are stopped for high wind speed.

The invented wind turbine works in all wind conditions by defending blades from crashing in high winds, while preserving high power output capacity.

To enable that, a wind turbine of our invention has a hollow cylindrical barrel- shaped housing that covers and protects from strong winds a lower part of the blades.

Additionally, our wind turbine structure allows rotating it according to changing direction to the highest wind and keeping power constant by changing of speed in gearbox according to wind speed or RPM (Revolutions per minute) of turbine shaft.

Additional advantage to using our wind turbine is in using magnetic gearbox which increases longetivity of the entire turbine. The typical design lifetime of a utility wind turbine is 20 years, but gearboxes are one of the parts that break more frequently. Furthermore, the proposed magnetic gearbox of our invention is a multi-gear one, which aims to generate higher electric power output.

Large wind turbines are installed on towers, so that each unit occupies a large land area.

Further advantages of using a proposed invented system include reduced installation area (the system can be installed almost anywhere, including relatively small areas), and ease of transportation and installation.

The invention will be implemented in accordance with electrical standards, e.g.

National Electrical Code (NEC), or NFPA 70 in USA, to ensure the safe installation of electrical wiring and equipment. NFPA 70 is a part of the National Fire Codes series published by the National Fire Protection Association (NFPA), and includes voltage standards, certification and inspection requirements, etc.

There are a number of patents, patent applications and articles presenting novel concepts in wind turbines.

Molina in his US patent application 20170306924 titled: "Wind turbine for the production of electric power with multiple-blade vanes and horizontal shaft supported at the ends" describes a wind turbine which comprises a shaft supported at two ends on two towers, the lower half of which wind turbine is closed with a frustopyramidal shape so that the wind does not pass and generate a "hill" effect and applies thrust to the upper part of the system.

Unlike Molina’s patent application, the barrel-shaped housing structure of our invention allows to rotate the wind turbine so that the blades will face wind direction most of the time. Also, we solve the problem of high winds by changing the output through using multi-gear gearbox.

Electromagnetic turbines provide another aspect in wind turbine industry. Guina in his US 9,866,097 "High Speed Turbine" presents a number of configurations of a high speed electromagnetic turbine. In Guina, the turbine includes a housing includes at least superconducting coilfor the generation of a magnetic field, the coil being retained within a cryogenic envelope of a cryogenic body.

Constant electricity producing turbine is disclosed in US 20110221191 by Fiset titled: "Mechanical regulation of electrical frequency in an electrical generation system". In Fiset, when the wind is strong, the speed of the wind turbine, may rotate faster, at 2000 rpm for example. In order to compensate for such a higher rotation speed of the rotor, the stator is rotated at 200 rpm in the direction of rotation of the rotor. The relative speed between the rotor and the stator is thus 1800 rpm [2000 rpm-200 rpm=1800 rpm]. If the speed of the rotor decreases due to weak winds for example, e.g. at 1500 rpm, the stator is rotated at 300 rpm in the direction opposite to the rotor. Fiser uses stator movement to produce constant electricity, while in our invention constant electricity is produced using multi-gear gearbox. Additionally, in Fiset, only HTz production is constant, while in our invention both Watt and HTz are constant.

The gearbox in existing wind turbines has only a single gear, i.e. it does not change gears, as it has a single gear ratio between the rotation of the rotor and the generator.

Some of the unique features of our invention are facilitated by using multiple gear (multi-gear) gearbox in the invented wind turbine. This could be facilitated by using either a mechanical multi-gear gearbox or a magnetic multi-gear gearbox.

An example of novel mechanical multi-gear gearbox that maximizes the electricity output while preserving longetivity advantages of the magnetic gearbox is presented in an article "Dynamic Optimization of Drivetrain Gear Ratio to Maximize Wind Turbine Power Generation" by John F. Hall and Dongmei Chen.

Hall and Chen show the proposed configuration of a Variable Ratio Gearbox (VRG)-enabled drive train, which consists of a turbine rotor, brake, main gearbox, six-gear VRG, and a generator, when the VRG works in conjunction with the main gearbox. The actual design intention is for gear shifting to occur in response to the mechanical torque. Control through this parameter enables the generator to run at full capacity without damaging the generator.

A practical example of a magnetic based multi-gear gearbox is presented in an article "Design and Analysis of a New Axial-Field Magnetic Variable Gear Using Pole-Changing Permanent Magnets" Mu Chen (and others) presents a new non- rare-earth axial-field magnetic variable gear (MVG). http://www.jpier.org/PIER/pier153/03.15072701.pdf In this paper, by real-time changing the numbers of permanent magnet pole-pairs in the input and output rotors, the gear ratio becomes controllable, hence achieving multi-gear capacity of the gearbox. The article proposes a new stationary ring integrated with magnetizing windings, so that different permanent magnet pieces can be independently magnetized to form different pole-pair numbers.

A paper by Frank and Toliyat titled: "Gearing ratios of a magnetic gear for wind turbines" further explains additional characteristics of a magnetic based gearbox. https://www.researchgate.net/publication/224506013 . In this paper, a magnetic gear is proposed to reduce the size of the generator and achieve similar torque reduction provided by a mechanical gearbox, without the maintenance and breakdown issues.

With regard to the dual rotor aspect of our invention, dual rotor wind turbine has been proved as efficient in a number of academic researches. An article titled "Novel Dual-Rotor Turbine for Increased Wind Energy Capture" by Rosenberg shows a new increase in power generation of 4.6% (http://iopscience.iop.org/article/10.1088/1742-6596/524/1/012078/pdf ).

One example of a dual rotor wind turbine is a one presented by Airgenesis Company and is detailed in US Patents 8,178,991 and 8,710,694. The wind turbine apparatus disclosed in those patents utilizing multiple generators coupled through a radius adjustable coupler to at least one rotational movement element such that said coupled connection is dynamically movable across the surface the rotational movement element so as to maintain an electrical output at a constant generator rotation per minute.

DETAILED DESCRIPTION OF THE INVENTION It would be desirable to have a wind turbine generating electrical power in all wind conditions, having constant power output and without energy contribution other than wind energy to start its rotation.

Therefore, to overcome the shortcomings of the prior art, the invented wind turbine is presented.

Other features and advantages of the present invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the figures thereof.

The invented wind turbine will be connected to an electric grid to receive power for making yaw motors work.

The general overview of the invented wind turbine is graphically described in Fig. 1.

The invented wind turbine comprises several blades 101, each blade being attached to a horizontal shaft of the wind turbine, the antipodal ends of said horizontal shaft being attached to on a hollow cylindrical barrel-shaped housing 102. The barrel-shaped structure of the housing allows rotating the wind turbine in such a way that the blades will face the oncoming wind direction. The blades are arranged symmetrically with respect to the horizontal shaft.

The number of blades and its size can vary depending on the wind turbine characteristics, location and local wind conditions. That way the invented wind turbine can get maximal amount of electricity in virtually any location.

The abovementioned housing covers the blades within its cavity when they are located in the lower part of the turbine while leaving the blades unprotected when they are located in upper half of the wind turbine, so that when the wind blows on the blades in the upper half of the wind turbine, the shaft of the wind turbine begins to rotate without the need in electrical power to start the wind turbine.

The wind turbine cylindrical barrel-shaped housing 102 could also be used as a water tank reservoir for storing water, thus, essentially, making the invented wind turbine a dual-purpose device. Water tanks are used to provide storage of water for use in many applications, drinking water, irrigation agriculture, fire suppression, agricultural farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses. The dual-purpose feature is especially beneficial in desert areas and areas experiencing water shortages. To facilitate that, the invented wind turbine will have drainage ports 103, 104 situated on the side of the said housing to prevent water from reaching a certain predetermined level below the bottom part of the blades.

In one embodiment of the invention, the water will also be harvested from the ground near the wind turbine reservoir. To facilitate such ground water harvesting and to increase the amount of rainwater runoff within ground catchment areas, it is necessary to increase the slopes 105,106 of ground by artificial means.

In order to prevent rainwater from evaporating, the land needs to be covered by plastic sheets, asphalt, flat sheets of galvanized iron or tiles along with slope. The water inlet pipes 107, 108 shall be terminated at least 90 degree around the reservoir perimeter from the outlet pipe and shall be arranged so that the incoming water directed away from the outlet pipe.

The inlet pipes shall include a non-return valve to restrict water from entering the pipeline. There are a number of non-return valves available in the market for the water lines. The non-return valves can be adjustable and can cope with different water working pressure: normally, commercially available non-return valves come with 16, 25 and up to 100 bar. Accordingly, a suitable non-return valve can be installed depending on the expected water flow and on the maximal water capacity of the water tank reservoir.

Water outlet pipe 109 will facilitate water outlet from the barrel-shaped housing.

The outlet pipe shall be raised at least 100mm above the level of floor to minimize the risk of any accumulated sediment within the reservoir being disturbed and being discharged during reservoir operation.

In main embodiment of the invention, a special shelf 110 will be built on the circumference of the said housing structure. Power production elements of the wind turbine (such as, generator, gearbox, yaw motors assembly, etc.) will be put on such a shelf.

The invented wind turbine should also comprise a ladder for carrying out maintenance and repair services. The ladder could be fixed to the barrel-shaped housing of the wind turbine using mechanical fasteners, clamp brackets etc.

Fig. 2 graphically presents an overview of the main elements of the invented turbine.

One of the main goals of the invented wind turbine is to rotate it according to the wind direction, so that the blades will face oncoming wind direction most of the time. To facilitate that, anemometers (automatic speed measuring devices) and wind vanes on the back of the nacelle 201 provide measurements of the wind speed and direction.

Using these measurements, the entire top part of the turbine can be rotated by a yaw motor 203, so the blades will face directly into the oncoming wind and will capture the maximum amount of energy, by using a controller 202 that sends signals to the motor.

As the blades facing wind direction, the wind moving air toward the turbine's blades 204.

The blades capture some of the kinetic energy from the wind, and turn the horizontal shaft 205. The shaft will be connected at its two antipodal ends to the abovementioned cylindrical barrel-shape housing. The RPM of the shaft 205 will be calculated by using a tachometer (revolution-counter) shaft rotation measuring device 206.

The gearbox 207 converts the low-speed rotation of the slow drive shaft into high-speed rotation of shaft 208 fast enough to drive the generator 209 in an efficient manner.

The gearbox in a wind turbine does not usually "change gears", as it normally has a single gear ratio between the rotation of the shaft and the generator. In our invention, we are using novel multiple-gears gearboxes as described in the prior art section of this application. The multiple-gear gearbox can be either a mechanical gearbox or a magnetic gearbox.

With such a gearbox, we convert between slowly rotating, high torque power and high speed, low torque power, which we use for the generator.

One of the main advantages to using a multi-gear gearbox is in enabling constant power watt production. Constant power production is achieved through the multiple gear (multi-gear) gearbox by changing of speed in gearbox according to wind speed or RPM of turbine shaft. For that, a mathematical model will be built. Number of watts needed to produce a certain amount of energy will be a major input of such a model, together with a number of blades, blades size and mass data. Gear ratio RPM increment coefficient incrRPMCrepresents a ratio between the RPM of shaft and the generator Shaft LastincrRPMRPM RPM C / = As detailed in the prior art section of this application, one example of a mechanical multi-gear gearbox that could be used in our invention is presented in an article "Dynamic Optimization of Drivetrain Gear Ratio to Maximize Wind Turbine Power Generation" by John F. Hall and Dongmei Chen. In the above article, the multi-gear (variable gear) gearbox works in conjunction with the main gearbox, which is used to produce the majority of the speed increase from the low speed rotor shaft to the high-speed generator shaft.

Magnetic gears can be an alternative solution to mechanical gears in a wind turbine. In general, magnetic gears offer several advantages, such as reduced maintenance costs, quieter operation, etc.

One example of a multi-gear magnetic gearbox that can be used in our invented novel turbine is presented in an article "Design and Analysis of a New Axial-Field Magnetic Variable Gear Using Pole-Changing Permanent Magnets" by Mu Chen(and others). The article presents a new non-rare-earth axial-field magnetic variable gear (MVG), wherein by real-time changing the numbers of permanent magnet pole-pairs in the input and output rotors, the gear ratio becomes controllable.

The generator 209 (a device that converts mechanical energy into electrical power for use in an external circuit), immediately behind the gearbox, takes kinetic energy from the high-speed shaft 208 and turns it into electrical energy.

The electric current produced by the generator flows through a cable running down through the inside of the turbine tower.

A step-up transformer converts the electricity to about 50 times higher voltage so it can be transmitted efficiently to the power grid (or to nearby buildings or communities).

If not for constant electricity power output, than the issue of energy storage becomes important, since wind power generation by the wind turbine is not correlated with the demand cycle. Graphical illustration of wind turbines farm with power storage feature is presented in Fig. 3 - in a 25 wind turbines farm, a battery is placed near each wind turbine. Energy storage by rechargeable lead acid batteries provide a suitable energy storage solution as they are well suited to trickle charging and have a high electrical output charging efficiency of 80%-90%.

Those batteries are low maintenance and have a low self-discharge rate of approximately 0.1% of the rated capacity per day. When needed, the electricity is released from the wind farm to users.

The blades in the invented wind turbine will rotate in such a way that they will be facing directly into the wind and capture the maximum amount of energy.

Graphical description of that mechanism is provided in Fig. 4.

The barrel-shaped housing of our invention 401 has runners 402 fixed to the circumference of the said housing. The lower part of the blades thus will be located within the cavity of the housing.

The shaft 403 will be fixed horizontally across the barrel-style housing structure.

The yaw motors 404, 405 (one or more motors, depending on turbine characteristics) move the shaft in accordance with the direction of the wind, they will be attached to those runners by a fixing mechanism. So, the yaw motor will move along these runners, so that the blades will always face the wind.

To facilitate the above mechanism, anemometers and wind vanes on the back of the nacelle 406 provide measurements of the wind speed and direction. There is a small sensor at the foot of the wind vane that notifies the wind turbine controller of the wind direction, and the controller sends signal to yaw motors.

The voltage generated by a wind turbine is generally non-grid compliant. In order to supply the transmission network with power from these turbines, the signal must pass through a power converter, which ensures that the frequency of the voltage of the electricity being generated by the wind turbine is the frequency of the transmission system. Power converters first convert the signal to DC, and then convert the DC signal to an AC signal.

Dual rotor wind turbine has been proved as efficient in a number of academic researches, dual rotor feature enabling to generate more power output.

In one embodiment of the invention, the inventive system includes double rotor and double gear box configuration wind turbine. In such a wind turbine, wind power generation system coupler engages and adjusts multiple generators to optimally produce an electrical output. The double rotor configuration system requires two shelves to be installed on two sides of the wind turbine.

In further embodiment of the invention, the invented wind turbine further includes the LED wiring wrapped around the blades (lengthwise and crosswise) or a flashing LED light and sound device - such an embodiment could be facilitated by using a bird repeller activated with flashing LED light and harmless sound to repel birds away from the turbine.

The impact of wind turbine on birds, which can fly into turbines directly, or indirectly have their habitats degraded by wind development is estimated to be in hundreds of thousands of birds per year.
