A habitat friendly, pressure conversion, wind energy extraction system is disclosed for safely extracting usable energy from wind. The system includes one or more shrouds or concentrator wings that convert the dynamic pressure of wind into relatively lower static pressure and thereby induces a vacuum that draws wind into a turbine centralized within the shrouds or concentrator wings. As such, the turbine impellor blades may be significantly smaller than the large diameter rotor blades of current popular designs and may be enclosed within the shrouds or concentrator wings that present themselves as highly visible objects and as such are easily avoided by birds in flight. The novel system in particular includes a device and method of airflow regulation than minimizes or prevents the stalling, or the generation of a turbulent flow of wind over or between the shrouds or concentrator wings. This stalling has been shown to occur when airflow is quickly accelerated by force of vacuum and drawn out of the turbine shroud which then mixes with and disturbs the otherwise smooth flow of wind over or between the shrouds or concentrator wings. The system may also include an aerobrake that responds quickly to protect the impellor blades or associated mechanisms from overspeeding or exceeding other design limitations under gusting or violent wind conditions. The system may also include a method of guiding elements of the system to orient appropriately into prevailing winds, and a method to support elements of the system, without unduly impeding the free flow of wind. Other advantages and objects are as well disclosed that increase safety and efficiency, increase installation potential, reduce costs and expenses, and minimize negative environmental impact.

An automatic protective shutter system that is controlled by atmospheric and or human intervention conditions. The shutter consists of a net that can be deployed automatically to cover any opening in a building structure. The shutter net can withstand high winds such as are prevailing winds in a hurricane. The shutter net can also withstand any projectiles that are being encountered in a hurricane. The shutter also protects against the incidence of high ultraviolet UV rays and/or excessive light. The shutter net also detects any tampering by a burglar or vandalism to shut down the opening or to sound an audible alarm. The shutter system is also extremely useful as a shield against the intrusion of insects. The protective shutter system can be controlled locally or by a remote system. The remote system would include a computer system operating through the internet. All of the above can be detected by various sensors such a high wind sensors, ultraviolet sensors and proximity sensors. The shutter net itself has an established surface frequency that operates within tolerable limits to generate a signal when that frequency is disturbed or changed to indicate a disturbance.

An omnidirectional building integrated wind energy power enhancer system is configured to produce electrical power from a wind turbine(s) concealed within and/or on top of a building by means of a flow of pressurized air from the prevailing wind that enters and flows through a portion of a building. A building may provide large exterior surface areas for receiving and directing airflow to the turbine(s). At least a portion of the wind energy power enhancer system is configured within a building, such as between floors, on a single floor, and/or a roof structure. The wind turbine(s) may be configured to receive airflow directly from an inflow chamber that is configured with a building, or from a flow tube coupled with the inflow chamber. Air deflectors may be fixed or dynamic to direct air flow into a flow tube regardless of the direction of the incoming airflow relative to the building.

A stall control wind turbine is eguipped with a latchable furling mechanism so that, except in the event of a fault condition or dangerously high winds, the rotor faces directly into the prevailing wind while generating power. A fault condition may occur when the electrical power grid, to which the wind turbine is connected, fails, when the alternator armature winding develops an open circuit and causes an unloading of the turbine, or when the gearbox breaks, also causing an unloading of the turbine. For a preferred embodiment of the invention, the release mechanism employs an electromagnet, which when energized, maintains the tail boom locked in place and the tail in the proper position to maintain the aerodynamic force. The wind turbine may also be eguipped with an electrically released mechanical brake and a back-up centrifugal brake.
