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 pump configuration includes a single VFD configuration, the single shaft electric motor, and the single shaft hydraulic pump mounted on the single pump trailer. The single VFD configuration converts the electric power at the power generation voltage level distributed from the power distribution trailer to a VFD voltage level and drives the single shaft electric motor to control the operation of the single shaft electric motor and the single hydraulic pump. The VFD voltage level is a voltage level that is required to drive the single shaft electric motor. The VFD configuration also controls operation of the auxiliary systems based on the electric power at the auxiliary voltage level.

Certain embodiments of the present application relate to a variable frequency drive (VFD) cabin for a pump configuration including a mobile trailer on which the VFD cabin is to be mounted. The VFD cabin generally includes a medium-voltage VFD and a ventilation system. In certain embodiments, the ventilation system is configured to generate an overpressure condition within the cabin to discourage the entry of dust and debris into the cabin. In certain embodiments, one or more components of the medium-voltage VFD are coupled to the floor of the cabin via a vibration damping system. In certain embodiments, the VFD cabin may be directly coupled to a chassis of the mobile trailer without an intervening suspension being provided between the VFD cabin and the chassis.

An electric power generation system is disclosed to produce electrical energy. The electric power generation system includes a solar awning that is ideally carried by a vehicle that is operable under its own power or towed behind a lead vehicle. The solar awning has a solar base attached to the roof of the vehicle and a pair of solar arms that are hingedly connected to respective opposite sides of the solar base. Each of the solar base and the pair of solar arms has an array of solar panels that convert solar energy to electrical energy. The solar awning is folded from an open configuration for maximum exposure to the sun at which the solar arms lie side-by-side the solar base to a closed configuration for minimum exposure to the sun at which the solar arms rotate downwardly from the solar base to lie alongside the vehicle.

A wheel-mounted air compression apparatus for maintaining a predetermined inflation pressure of a tire mounted on a wheel of a vehicle and the tire having an inflation port includes a housing defining an air compression chamber and has an air compressor device positioned therein. The apparatus includes a plurality of support legs spaced apart from one another. Each support leg is attached to the housing and extends away therefrom and may include a pair of sleeves that are length-adjustable for mounting to wheels of various sizes. A pressure sensor is situated in the housing and operably connected to the air compressor and to a nozzle for determining a current pressure of air within the tire. A controller or other electronics cause the air compressor to pump air into a tire if the air pressure therein is detected as declining below a predetermined amount.

A power generation transport includes a gas turbine, an inlet plenum coupled to an intake of the gas turbine, a generator driven by the gas turbine, and an air intake and exhaust module including an air inlet filter housing, an intake air duct coupled to the housing at a first end and to the inlet plenum at a second end, and an exhaust collector coupled to an exhaust of the gas turbine. The transport further includes at least one base frame. The frame mounts and aligns the gas turbine, the inlet plenum, the generator, and the air intake and exhaust module. The intake air duct is mounted on the base frame so as to be disposed underneath the gas turbine, and extend along the base frame from an exhaust end side of the gas turbine to an intake end side, in a longitudinal direction of the power generation transport.

The present invention relates to a wind powered, electrical power generating system for vehicles. The system uses inexhaustible and clean wind energy to produce electrical power for an electric vehicle. The system includes at least one wind turbine positioned to capture wind and coupled to an electromechanical generator for converting the wind into electrical power. The electrical power produced by the generator is stored in a battery pack, for providing electrical power to the DC motor of the vehicle. The battery pack includes three batteries, which either provide power to the DC motor, or are recharged by the generator, depending on their respective power levels. An auto change component swaps the first battery for the second battery, when the power level of the first battery falls below a predefined threshold value.

A portable system for converting wind energy into electrical energy is disclosed. The disclosed system may include a frame hosting one or more conversion modules, arranged as desired. A given conversion module may include one or more wind energy conversion devices (WECDs), arranged as desired. The conversion modules may be electrically connected, directly or indirectly, with one or more downstream electrical energy storage elements (e.g., such as a battery or other capacitive element, optionally native to a host platform). In this manner, the disclosed system may be configured for use in storing and/or supplying electric power for downstream consumption by a host platform or otherwise. In a more general sense, the disclosed system may be utilized, for example, for micro-generation of renewable electrical energy from wind.

A wind turbine blade rotating and braking apparatus comprising: a root device including: a root support member having an upper surface with a radius of curvature and configured to receive a portion (e.g. root) of a wind turbine blade, rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; braking mount on the sides of the root support member; and a braking mechanism (e.g. strap or band) fixedly attached to the first mount, releasably attached to the second mount and extending above the blade to apply a braking force to the blade. Once applied, the braking force can be maintained by a locking pin.

A vehicle incorporates a gravity-assist energy harvesting suspension system including one or more gravitational positive displacement pumps. The positive displacement pump has a cylinder and a reciprocating piston inside the cylinder. The piston is adapted for movement along a compression stroke and an opposite extension stroke in response to a gravitational bounce of the vehicle when in motion. A turbine comprising a rotor shaft and attached blades is mounted relative to a distal end of a fluid outlet hose connected to the pump. Fluid discharged through the outlet hose acts on the blades, thereby moving and imparting rotational energy to the rotor shaft. A generator is operatively connected to the turbine, and is adapted for converting the rotational energy generated by the rotor shaft to electrical energy.

A system and methods are provided for a wing stabilizer charging system for recharging onboard batteries during operation of an electrically powered vehicle. The wing stabilizer charging system comprises a wing stabilizer configured to be coupled with a rear of the vehicle. One or more air inlets are disposed in the wing stabilizer and configured to receive an airstream during forward motion of the vehicle. Wind turbines are disposed within the wing stabilizer and configured to be turned by the airstream. A circuit box is configured to combine electricity received from the wind turbines into a useable electric current. A power cable extends from the circuit box and is configured to supply the useable electric current to any one or more electronic devices, such as any of an onboard battery for powering the vehicle, mobile phones or smart phones, portable music players, tablet computers, cameras, and the like.
