摘要:
The present invention is a new and novel wind generator system particularly suitable for small wind applications that harnesses low velocity wind effectively. In a preferred embodiment of the invention, the wind generator system comprises a drive shaft; one or more retreating blades and one or more advancing blades attached to the drive shaft and extending radially outwardly therefrom; a generator assembly coupled to the drive shaft and effective for generating electrical power; and a housing having an inner chamber for receiving the blades and a wind directional apparatus that operates to adjust the speed of the wind and to channel wind along a desired flow pathway towards the one or more of the retreating blades and blocks airflow from impinging on one or more advancing blades.

The power output of a wind power station with a Darrieus Rotor is enhanced by wind guides positioned around the Darrieus Rotor to form a wind concentrator. The wind guides include at least two parallel wind deflection plates, displaced along parallel direction with respect to each other.

A shroud for vertical axis wind turbines. The shroud contains vanes that direct airflow to the turbine blades to increase efficiency. The vanes in the shroud further provide a means to close entirely the turbine from adverse weather conditions. The vanes are operated utilizing electrical feedback from the rotational speed of the turbine.
摘要:
A wind turbine having one or more sets of opposing magnets to create an opposing force between a turbine support and a turbine rotor great enough to form a space between them thereby reducing friction between the turbine support and the turbine rotor. The reduction of friction between the turbine rotor and the turbine support allows for an increase in energy production and scale of the wind turbines.

A vertical axis wind turbine (1) comprises three vertically extending sails (8) where each sail (8) comprises a strip (80) of substantially constant width. The opposite ends of each sail (8) are longitudinally twisted to have a pitch angle of approximately 90 degrees. The turbine (1) further comprises a vertically extending central core (7) and a vertically extending opening (9) between each sail (9) and the core (7). Also disclosed is an improvement in a vertical axis wind turbine (91) having at least one main blade (94) each of which has a longitudinal extent and a longitudinally extending radially outermost edge (924). The improvement comprises a longitudinally extending auxiliary blade (944) spaced from the main blade (94) to define a venturi inducing gap (99) between the main blade (94) and the auxiliary blade (944) whereby the turbine (91) has a zone of influence which extends radially beyond the maximum radial extent of the blades.

A wind turbine, including: a rotatable frame; a plurality of airfoils extending in a direction parallel to an axis of rotation of the rotatable frame; and an enclosure surrounding the rotatable frame, wherein the enclosure comprises a plurality of moveable members configured to direct air flow onto a first half of the rotatable frame and to block air flow onto a second half of the rotatable frame to thereby cause the rotatable frame to rotate. The moveable members may be pivotable louvers that can be opened by being oriented in a direction parallel to the direction of the air flow. By changing the orientation of the pivotable louvers, the present wind turbine can generate electricity from winds blowing in any direction.

The invention provides a bi-directional programming method/system/computer product for a programmer to enter source level instructions via either a visual language interface or a traditional syntactic level (code) interface. Irrespective of which means is used to describe the program, a corresponding “view” of the program (visual or syntax) is generated. Changes to the program can be made at either level, allowing the regeneration of the corresponding view (visual or syntax) to reflect the changes. For example, should the original program be described in a visual format, then a program can be generated in the corresponding syntax level format. Similarly, if a programmer wishes to make changes to this syntax level, then the equivalent version of the program can be regenerated in the visual format to reflect the changes. The invention can advantageously be used to develop back-end logic for an application program.

The invention describes an Atmospheric Vortex Engine in which a tornado-like convective vortex is produced by admitting air tangentially in the base of a cylindrical wall (101). The vortex is started by heating the air within the circular wall (101) with fuel. The heat required to sustain the vortex once established can be the naturally occurring heat content of ambient air or can be provided in a peripheral heat exchanger mean (83) located outside the circular wall. The heat source for the peripheral exchanger mean can be waste industrial heat or warm sea water. The preferred heat exchange mean is a crossflow wet cooling tower. The mechanical energy is produced in a plurality of peripheral turbines (61). A vortex engine could have a diameter of 400 m; the vortex could be 100 m in diameter at its base and extend to a height of 1 to 15 km; the power output could be in the 100 to 500 MW range. The vortex process could also be used to produce precipitation, to cool the environment, or to clean or elevate polluted surface air.

Disclosed herein is a guide vane assembly including a rig structure configurable with a turbine and having an inner portion and an outer portion forming extremities thereof, a sail and an actuator assembly. The sail is coupled to the rig structure and shaped for presenting a trough to a flow of impinging fluid, the trough having a depth defined from the rig plane. The sail extends from the outer portion towards the inner portion of the rig structure to terminate at an inner edge whereat a vent is defined. The fluid impinging on the sail is concentrated at the trough and redirected towards the turbine from the vent.
