A rotor which comprises at least one blade and at least one fluid routing device that is mechanically connected to one of the blades so that a fluid inlet thereof is placed in a lateral edge of the blade. The fluid routing device has a continuous channel with an inlet facing the opposite direction of rotation of the blades and an outlet. The continuous channel is sized and shaped to conduct fluid passing via the inlet. The fluid routing device includes a flow directing element that is mechanically connected to the outlet so as to direct the conducted fluid to adjust fluid flow in or on the mechanically connected blade.

Tethered unmanned aerial vehicle (TUAV) includes at least one wing fixed to a fuselage. The wing is comprised of an airfoil shaped body capable of producing lift in response to a flow of air across a major wing surface, and can include at least one flight control surface, such as an aileron. One or more buoyancy cell is disposed within the fuselage for containing a lighter than air gas to provide positive buoyancy for the TUAV when the TUAV is disposed in air. A tether attachment structure facilitates attachment of the TUAV to a tether which is secured to an attachment point for securing the TUAV to the ground when aloft. A wind-powered generator is integrated with the TUAV and configured to generate electric power in response to the flow of air across the least one wing when the TUAV is aloft.

A negative pressure air suction type fluid-driven power machine comprises a fluid pressure accumulation bin, a necking port, a flow inlet, a flow guiding cover, a fluid-inlet flow guiding cover, turbine driving blades, a turbine housing, a turbine shaft, a turbine bracket, nozzles surrounding peripheries of the turbine driving blades, a turbine fluid outlet, a fluid negative-pressure flow guiding cover, a fluid negative-pressure outlet, an external driving fluid inlet, an external driving fluid flow guiding cover, and nozzles. The negative pressure air suction type fluid-driven power machine is formed using a gravity acceleration fluid generated by a fluid flowing to a direction opposite to operation of an object as a main driving power source and using a fluid air suction phenomenon as an auxiliary power source, and can replace some effects of steam engines, internal combustion engines, motors and the like.

Invention relates to the field of solar energy. Power station, which has the air stream directional body, at least a pair of generator connected with wind turbines, tough combined greenhouse to the lower end of the body, the external surface of the of which is painted by matt black paint, and due to invention, it (body) is situated on the slope of the mountain, the greenhouse is being realized in the form of body entrance section, and the entrance of which is widened due to the height and width toward body. Before the greenhouse the black color material layer is located on the surface of the earth, and inside there are full of water reservoirs. The power station additionally has electrical air heaters located along the body, heat exchange system and least one horizontal acceleration cell, which is toughly connected with the upper end of the body and has a narrowing transverse cross section. At the free narrowing end of the acceleration cell, a passing cell is situated, at the exit of which a generator fixed to turbine is located. Heat exchange system has a lower radiator, which is located at the body entrance section and an upper radiator; located at the acceleration cell entrance section. Lower and upper radiators are connected with each other by pipes located along the body. The objective of the invention is to rise the EC of the power plant.
