A wind power generation device includes a rotor assembly and a stator. The rotor assembly includes a rotating member, a first magnetic module, and a second magnetic module the latter two of which are fixed on the rotating member. The rotating member has a column and a spiral blade connected to the column. The first and second magnetic modules are arranged outside the spiral blade and face each other. The rotor assembly defines an annular gap formed around the spiral blade and between the first and second magnetic modules. The stator assembly includes a frame, a positioning member connected to the frame, and an induction module fixed on the positioning member and arranged in the annular gap. The spiral blade can rotate the rotator assembly relative to the stator assembly by wind, so that a region between the first and second magnetic module sweeps over the induction module.

Systems and methods to generate electrical power through a direct drive wind turbine. In one aspect, the system uses a diffuser cuff surrounding a counter rotating turbine operating inside a streamlined center body, the counter rotating turbine using a generator with an iron sandwich core. The main wind turbine blades are attached to a barrel stave that increases generator efficiency and distributes loading through the tower support structure.

A transportation vehicle may be equipped with electrical energy harvesting systems to harvest electrical energy for use. By way of example, in the transportation vehicle, a Venturi system may be used to receive an air flow and the speed of the air flow increase in a constricted area of the Venturi system, the air flow containing a large amount of kinetic energy. A plurality of electrical energy harvesting systems is disposed in the Venturi system and is configured to convert the kinetic energy contained in the accelerated air flow into electrical energy that can be used to power on-board electronics as well as one or more on-board batteries in the transportation vehicle, as the transportation vehicle is in motion.

A wind power plant includes a shrouded wind turbine having an annular shroud which defines a longitudinal axis and which is rotationally symmetrical thereto. A radially inner upper side of the shroud forms a flow channel for the wind, wherein a propeller which can rotate about the longitudinal axis and is intended for driving an electrical generator is rotatably mounted in the flow channel. A support, which defines a support longitudinal direction, has arranged thereon an annular shroud bearing element on which the shroud, and hence the wind turbine, can be mounted in different pivoting positions about a pivot axis, which extends transversely with respect to the support longitudinal direction.

The Wind Wall is a solid structure composed of one or more Wind Cells, arranged adjacently, one next to the other, in an orderly and symmetrical way, in such a way that as a whole they form a continuous structure of Wind Cells, sustainable by itself and modular along the three physical dimensions, where each Wind Cell has an inlet opening and an outlet opening, where the internal surface comprised from the inlet opening to the outlet opening has the shape of an extrados (upper face) blade profile in revolution, and where the inlet opening and the outlet opening are of equal or substantially equal dimensions.

The Wind Cell, being the constructive component of the Wind Wall, is an aerodynamic structure specially designed to increase the wind speed within a critical space and, therefore, increase the wind power available to be used by the rotor of a Wind Turbine. The increase in wind speed is achieved through the deliberate creation of environments with high pressure differentials and, at the same time, environments dedicated to maintaining laminar wind flow and mitigating turbulent flow.

The Wind Wall is by itself a new generation of Wind Systems based not only on the aerodynamic efficiency of the Wind Turbine, but also on the aerodynamic efficiency of the structure and environment surrounding the Wind Turbine. In this sense, the new generation of Wind Systems, based on the application of the Wind Wall, will be able to increase the wind speed and, therefore, increase the density of the underlying power, given the same wind resource available in nature, allowing this way a general increase in the capacity of generating electric power.
