Apparatus is provided for wind-energy electrical generation. The apparatus presented comprises a shell enclosing a turbine with a vertical axis, the shell having a wind intake and wind egress, and may comprise blades or vanes to direct wind flow inside the shell to push the turbine. The turbine comprises an electrical generator. The turbine axis may be able to tilt. The apparatus may be used for wind-energy electrical generation in sites that are not conducive to convention wind-energy electrical generation. The present disclosure solves problems with the currently available apparatuses for wind-energy electrical generation using a building or other obstacle to its advantage. It also provides a means of combining solar and wind renewal energy harvesting into a single device.

An apparatus for electricity generation is provided. The apparatus includes an air handling unit which absorbs air from an atmosphere and regulates a velocity of flow of the air. The apparatus also includes a hollow chamber which includes a first end and a second end, and provides a passage for the air. Further, the apparatus includes at least two conduits which includes an inlet end and an outlet end respectively, and receives the air from the hollow chamber. The apparatus also includes an electric power generation unit which includes a rotor which rotates at a pre-defined rotation speed, an electricity generator which generates a pre-defined amount of electricity and multiple outlets which releases the air. Furthermore, the apparatus includes a power management unit, wherein an electric power supply from the electric power generation unit is fed back to power the air handling unit.

A rotor assembly comprises a rotor having a plurality of blades and an axis about which the rotor rotates, each blade being spaced from the axis of the rotor such that there is a gap between the axis and an inner edge of each blade through which fluid can flow, and inner and outer edges of each blade lying in and defining a blade plane and each blade being offset from the axis of the rotor such that the axis does not lie in the blade plane; a casing partially surrounding the rotor, the casing having a first opening to permit a fluid flow into or out of the casing in a direction generally perpendicular to the rotor axis; and a second opening at an axial end of the casing to permit a fluid flow into or out of the casing in a direction generally parallel to the rotor axis.

A vertical wind turbine includes a shroud for directing vehicle-created wind towards the turbine blades, which are oriented in response to wind direction.

A system for generating electricity using wind power for an electric vehicle (EV). The system converts wind to electricity for charging the EV's primary batteries, or to provide supplemental electricity to other EV systems, such as heating and cooling. The system comprises an air intake that compresses air along a narrowing path to a turbine component. The turbine component comprises a cylinder housing a turbine for capturing the compressed air. As the turbine rotates due to airflow, it engages at least one alternator to generate electricity. The at least one alternator is then connected to the EV's batteries or other vehicle systems for charging or immediate use.

Provided is a wind power installation for converting the kinetic energy of the wind into the mechanical energy of rotation of a rotor for subsequent conversion of the mechanical energy of rotation into the electrical energy. A wind power installation includes a support frame, a shaft disposed on the support frame, and a blade system mounted on the shaft. The shaft is configured to rotate about a vertical axis and is functionally connected to an electric generator. The support frame is configured to be mounted between at least three radially arranged structures. The wind power installation can include additional blade systems disposed one above another on the shaft. Mounting the support frame between three radially arranged structures results in greater rigidity and robustness of the wind power installation, thus enabling the use of blade systems having a larger blade area and the arrangement of several blade systems on the shaft.

Air stream-driven power-generating systems for electric vehicles have been described and illustrated.

A wind generator assembly for harnessing wind to charge batteries in electric vehicles and hybrid vehicles includes a housing that is mounted on a roof of a vehicle. The housing has a wind passage extending therethrough and wind passes through the wind passage when the vehicle is driven. A turbine is rotatably positioned in the housing. The turbine is positioned in the wind passage and the turbine is rotated by wind passing through the wind passage. A generator is mounted in the generator space and the generator is in mechanical communication with the turbine. Thus, the turbine rotates the generator when the turbine rotates thereby facilitating the generator to produce electrical current. The generator is electrically coupled to batteries in the vehicle to charge the batteries.

A multistage wind turbine or network of wind turbines with improved and optimized wind-directing, wind-shaping, and wind-power conversion features indicates that the shapes of these features directly affect the ability of the multistage wind turbine to use the power of moving air, such as wind, to spin a rotor and create torque on a rotor shaft to generate electricity. The wind-power-conversion mechanical efficiency described significantly improves upon previous designs by conversion of wind energy into electrical power at a superior price-to-performance ratio compared with existing alternative energy technologies.
