Provided herein is a system and method for heat exchange of a vehicle. The system comprises an enclosure disposed on the vehicle. The enclosure comprises a vent at a base of the enclosure. The enclosure houses one or more sensors. The enclosure comprises a fan disposed at a base of the enclosure. The heat exchange system comprises an deflector disposed on the vehicle outside the enclosure and configured to direct an airflow into the vent of the enclosure. The heat exchange system comprises a motor configured to: generate electricity from the airflow and selectively supply electricity to operate the fan. The heat exchange system comprises a controller configured to adjust the deflector and regulate an amount of electricity supplied from the motor to the fan.

A wind funnel includes airflow chambers. Each airflow chamber has sidewalls forming an external cross-sectional area greater than an internal cross-sectional area. A wind turbine engine includes a turbine drum and the wind funnel. The turbine drum has turbine blades extending from the drum that rotate a centrally positioned vertical shaft. The airflow chambers conduct external air to, and increase air pressure compared to ambient air pressure by a predetermined ratio at, the turbine blades.

An energy-harvesting building structure has multiple levels, a vertical shaft (central vortex tower] to direct wind upward toward an outlet at the top, and multiple wind powered turbines in the shaft. Wind collection areas on multiple levels are exposed to multiple directions. Wind vanes pivot into a backstopped position for redirecting wind to spiral inward toward the shaft. Wind twisters receive and further redirect wind inward and upward into the shaft to feed an air vortex driving the turbines at different levels. Two concentric stages of wind vanes may be included within wind collection areas, with the inner stage vanes having a surface which deforms in one direction but not the other. The building can include occupancy zones between wind collection levels. Heated air can be released into the bottom of the shaft to feed the vortex. At a top level, another wind turbine can draw wind up the shaft.

Wind turbine systems with wind directors are disclosed. The wind director is configured to simultaneously reduce drag force applied to a returning blade and increase force applied to an advancing blade. In some embodiments, the wind director includes an inlet having an inlet width configured to receive wind at a proximal end, and an outlet having an outlet width on a distal end opposite the proximal end. The wind director is configured to position near a wind turbine such that wind exiting the outlet is applied to an advancing blade of the wind turbine. Furthermore, the wind director provides a barrier to a returning blade opposite the first blade, thereby reducing drag force applied thereto. The wind director may further comprise a secondary duct which has an angled outlet and is configured to apply an additional force to the returning blade.

Electric and hydrogen technology automobiles and vehicles such as trucks, buses, ships and boats are believed to be the future of transportation; however for the time being, the problems surrounding the technologies are significant and have kept the consumers away for various reasons including the capacity of batteries and fuel cells, the lack of filling stations, and most of all the limited distance the vehicles can travel without a recharge, which for small electric vehicles can take up to 20 minutes before they can continue to travel with a full battery or fuel cell. Commercial vehicles in particular; cannot take the time to stop frequently and worst yet take the significant amount of time that it would take to recharge their systems. Hybrid vehicles still rely on gasoline which is available to increase the travel distance, but customers concerned for the environment have not yet embraced the solution and larger vehicles such as commercial trucks are not about to take the risk of being left out without fuel under any circumstances. This current invention “Airflow Power Generating Apparatus’ is for use in present and future electric and hydrogen technology vehicles and solves the challenges present today as it provides a system to charge batteries and fuel cells while the vehicle is moving forward. This system will extend the distance vehicles can travel or may eliminate completely the need to recharge batteries of fuel cells at homes or at charge stations.

An electricity generator includes a wind tunnel positioned on the vehicle. The wind tunnel has an open first end and an open second end. The open first end is in communication with ambient air. A turbine chamber is fluidly coupled to the open second end of the wind tunnel. At least one wind turbine is positioned in the turbine chamber. The at least one wind turbine includes a housing. A rotor is positioned in the housing along an axis that is substantially perpendicular to an axis of the wind tunnel.

A wind power generator includes a vertical axis type wind power generation mechanism and a support mechanism. The wind power generation mechanism includes a wind collector, a windmill with a plurality of blades, a windmill rotation shaft, and a generator. The wind collector is formed to surround an outer circumference of the blades. The generator is directly connected to the windmill rotation shaft. The support mechanism includes a mount, and an attitude control means. The wind power generator installed in a stationary state enables to generate power, or the wind power generator fixedly installed on a moving body enables to generate power. The A rear end portion of a horizontal axis type wind power generation mechanism is detachably connected to a lower end portion of the vertical axis type wind power generation mechanism.

Disclosed is a vertical axis wind turbine air concentration tower with reduced radar cross section. The air concentration tower has a polygonal outer perimeter, a pivot located at each vertex of the polygonal outer perimeter, and an inwardly-positioned rudder blade operatively connected at each pivot. Each inwardly positioned rudder blade has a first wind-neutral position, and is pivotable through a plurality of angles that adjust based on an incoming wind direction, such that the incoming wind is channeled to the vertical axis wind turbine, which is located approximately at a center area of the polygonal outer perimeter. A radar absorbent material is applied to the vertical axis wind turbine air concentration tower to reduce the radar cross section. The air concentration tower is designed to provide higher wind speed to the vertical axis wind turbine than the surrounding ambient air.
