The box body includes at least one flexible housing member and at least one rigid housing member which enclose at least one sealed cavity. The first energy collecting unit includes a piezoelectric membrane and electrodes deposited on both sides of the piezoelectric membrane, respectively; the first energy collecting unit overlying on an inner wall of the flexible housing member and are located in the sealed cavity. An end of the first connection member is fixed to the flexible housing member so that the first connection member is connected to the box body and at least a part of the first connection member is located outside the sealed cavity.

Proposed is a wind turbine having a vertical axis rotor mounted in a fixed cylindrical housing provided with outwardly opening shutters. The rotor consists of a rotating core comprising core blades fastened between two circular bases and forming a Ugrinsky rotor, and an annular impeller configured for independent rotation about said core. The impeller comprises impeller blades fastened between two ring-shaped bases and forming a continuation of the core blades, wherein common inter-blade channels are formed which narrow toward the centre of the rotor. Also proposed are wind power stations based on the wind turbines described above, said turbines being mounted vertically one above the other to form a generating tower, or being mounted on a facade of a high-rise building. Technical result consists, in particular, in increasing the efficiency of the wind turbine and making it possible to incorporate wind power stations into an urban environment.

Invention relates to renewable Wind energy combining drag and lift forces into usable torque, having adjustable blades panels with sub blades. Its unique feature is to convert reverse drag into usable lift and combine the two forces in to one cohesive force. The system comprises output drive rotor arranged on a tower base, with its rotating arms with blade panel assemblies mounted rotatably. Each blade panel assembly comprises an auxiliary rotary shaft having sub-blade panels pivotable at one or more pivot points with primary or secondary control arrangements for blocking and/or allowing wind to pass through the blade panels partially or fully. The system further includes sensors to collect control information, coupled to Main Control Unit (MCU) and secondary control arrangements, configured to provide one or more energy forms.

The present disclosure relates to an apparatus (10) for wind power generation comprising at least one primary wind duct (12); at least one secondary wind duct (14); at least one pressure-balancing and guiding unit (14); at least one primary blade unit (20); at least one booster and generator unit (22); at least one secondary blade unit (24); and at least one extractor (26). Characteristically, a counter-rotating motion is created between the primary blade unit (20), the secondary blade unit (24) and the components of the booster and generator unit (22), which causes an increase in the velocity of the wind flowing through the apparatus (10) and a resultant increase in the impact of the high velocity wind on the blades; further amplifying the self-reinforcing effect occurring at each stage of the apparatus (10).
