Preferably, several wind energy modules can be connected in series and / or also in parallel with each other. Any wind energy module can be retrofitted and / or removed or replaced at any time.

In a further embodiment of the present invention, it is provided that the wind power installation has a base mount, in which wind energy modules can be adjustably attached via a respective mounting of the wind power module. The basic support can be designed, for example, as a rail, for example with latching means.

The fastening means may be designed so that attachment to a mobile and / or an immobile object is possible. Possible objects are motor vehicles, ships, roofs, buildings, bridges, containers and the like. The wind energy modules can be designed extendable / retractable, so that they can contribute, for example, in a braking operation to a brake effect increase by using the energy in addition to an induced by the unfolding brake resistor.

Yet another embodiment of the present invention provides that the base support and / or the holder is retractable and retractable. As a result, if necessary, the entire base bracket or even a portion of the base bracket can be retracted and extended. Preferably, the basic support is composed of several basic support sections, which are all individually controlled to realize a corresponding retraction or extension. Similarly, the holder may consist of several sections, which are for example telescopically designed to allow a corresponding positioning of the wind energy module or the wind energy modules. The sections can also be connected to one another, for example, by means of corresponding joints.

In yet another embodiment of the present invention, it is therefore provided that the basic holder comprises a plurality of basic holding elements, which are connectable to each other via joints.

In addition, a further embodiment of the present invention provides that the wind energy installation comprises at least one channel system, through which a fluid deflected by means of flow guiding means flows to a propeller in order to drive it and thereby generate energy.

In a preferred embodiment of the present invention, it is provided that the channel system is formed in a building, in particular in a high-rise building, preferably as a ventilation shaft. These ventilation shafts can direct an incoming fluid, here for example air, to a propeller with a generator.

Yet another preferred embodiment of the present invention provides that the flow guiding means are arranged on the outside of a building facade. Thus, a fluid flowing around the building can be used to generate energy.

In addition, a further embodiment of the present invention provides that the flow-guiding means comprise fins, preferably fins which can be folded in and out. These can be folded in at high flow velocities to prevent damage. According to the flow conditions, the slats can be adjusted.

The invention further includes the technical teaching that a use of a wind turbine according to the invention is provided for generating energy for an immobile unit, comprising vertically extending units such as houses, buildings, bridges and / or containers. For example, it is often possible to provide sufficient energy for container units used in disaster areas or developing countries or other energy-under-served areas. Such containers or container units can be used as office space, apartments, emergency shelters and the like. The wind energy module according to the invention can also be provided for a wind turbine for generating energy on a mobile unit, including wind power vehicles, engine-powered vehicles, motor and wind power vehicles, land vehicles, watercraft, aircraft and the like, in particular for use on trucks for energy support of the on-board power supply means Connect or extend. The wind turbine is retractable designed accordingly and extendable. In this way, for example, in a braking process, a brake energy recovery can be realized.

The wind energy module according to the invention has at least one propeller with at least one propeller blade. In the case of a propeller blade for a propeller, with a blade body, it is provided, for example, that the blade body has at least one nozzle unit which accelerates a fluid flowing against the blade body. To generate energy from wind energy, the propeller blade is flown. It flows around a fluid, such as wind, a propeller profile and due to the formation of the profile of the propeller blade is moved. In order to effect a movement of the propeller blade even at low wind speeds, a nozzle unit is provided on the wing body, which accelerates when the inflowing fluid flows, so that a greater energy can be obtained. The nozzle unit expediently comprises at least one inlet opening formed in the wing body. The nozzle unit may be formed on the propeller or in the propeller. In this case, the nozzle unit may be formed in the flow direction at the front or rear of the wing bodies. Preferably, the inflowing fluid flows through an inlet opening into the nozzle unit. In addition, the nozzle unit may comprise at least one outlet opening formed in the wing body. The fluid flowing in through the inlet opening can escape from the nozzle unit through the outlet opening, whereby the fluid flowing through the nozzle unit is thereby accelerated. Corresponding fluids are provided in the nozzle unit, for example, a cross-sectional change, which cause an acceleration of the fluid flowing through. As the accelerated fluid flows out, forces are generated which increase movement of the propeller blade, so that a greater amount of energy can be gained. The propeller blade of the propeller of the wind energy module extends radially from a rotatably mounted middle part. In this way, even at low wind speeds or flow velocities can effectively gain energy. The at least one propeller blade is desirably formed from a lightweight material selected from the group of materials having a specific gravity in the range of about less than or equal to 5 grams per cubic centimeter, preferably about less than or equal to 4 grams per cubic centimeter, more preferably less than or equal to equal 3 grams per cubic centimeter, and most preferably from about less than 2 grams per cubic centimeter. Due to the lightweight construction, the propeller blade can be used even at very low wind speeds or flow velocities from about 0.3 m / s, preferably from 0.2 m / s and more preferably from 0.1 m / s, whereby energy can be generated effectively. The propeller blade may also be formed of a composite material, for example a lightweight core and a fiber reinforced sheath. By this construction, a lightweight propeller blade is realized, which has a high strength and is suitable for different flow conditions. The propeller blade can be used, in particular, in a range from low flow velocities to high flow velocities, for example in the range of up to 55 m / s or more.

It is advantageous to form at least one of the propeller blades starting from a wing starting part of the middle part radially leading away with a loop area and due to a tip against the direction of the wing starting part to the middle part. Due to this special design, a propeller drive can be realized even at low flow velocities, so that electrical energy can be effectively obtained. Due to the special flow guidance due to the propeller shape, a high degree of efficiency can be achieved. It has also proven to be beneficial to connect the propeller blade with the top with the middle part. Due to the loop-like design with two different attachment points, a higher stability than, for example, with an attachment point can be realized. It is also possible to attach the propeller blades exchangeably via a detachable connection to the central part. In this way, different propeller blades can be used for different flow conditions, so that optimal energy production can always be achieved. Preferably, the propeller blades are attached by means of a quick-release device to the central part, so that a fast and possibly automated connection can be realized. Such a detachable connection may comprise, for example, a bayonet lock, with which the propeller blades are exchangeably fixed to the central part. In this way, a secure connection can be realized, which is easy to automate. In another possibility for easy replacement of the propeller blades connecting means are provided for exchangeable connection of the propeller with a component to make the propeller as a unit interchangeable. In this way, not only the individual propeller blades, but also the entire propeller can be easily replaced. It is also expedient to stow the propeller in order to compress it when not in use and / or to stow it small-sized. For example, the propeller can be folded together, displaced into one another, displaced one behind the other, folded in or the like, so that the least possible flow resistance after stowage is present. In particular, the propeller can be stowed after loosening the connection.
