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.

The system further includes an electric motor configured to convert electrical energy stored in the battery into kinetic energy. The vehicle is to be propelled by at least the electric motor.

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.

An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A power distribution trailer distributes the electric power generated by the power generation system at the power generation voltage level to the single VFD and converts the electric power at a power generation voltage level to a VFD voltage level and controls the operation of the single shaft electric motor and the single hydraulic pump. The power distribution trailer converts the electric power generated by the power generation system at the power generation level to an auxiliary voltage level that is less than the power generation voltage level. The power distribution trailer distributes the electric power at the auxiliary voltage level to the single VFD that controls an operation of the of the auxiliary systems.

An electric driven hydraulic fracking system is disclosed. A pump configuration includes the single VFD, the single shaft electric motor, and the single hydraulic pump mounted on the single pump trailer. A controller associated with the single VFD and is mounted on the single pump trailer. The controller monitors operation parameters associated with an operation of the electric driven hydraulic fracking system as each component of the electric driven hydraulic fracking system operates to determine whether the operation parameters deviate beyond a corresponding operation parameter threshold. Each of the operation parameters provides an indicator as to an operation status of a corresponding component of the electric driven hydraulic fracking system. The controller initiates corrected actions when each operation parameter deviates beyond the corresponding operation threshold. Initiating the corrected actions when each operation parameter deviates beyond the corresponding operation threshold maintains the operation of the electric driven hydraulic fracking system.

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 wind turbine blade handling apparatus for rotating and lifting a blade. The apparatus includes a root device having a root support member with a concave upper surface and rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; a base, and a scissor-lift mechanism with intersecting struts which converts from a lowered position wherein the struts are disposed in a generally coplanar configuration, to an elevated position wherein the struts are disposed in an angled configuration.
