Abstract
A wind motor having two sets of wind force collectors which rotate in a horizontal plane. One set is vertically displaced from the other and rotates in an opposite direction. One set is connected to the stator and the other to the rotor of an alternator. The wind force collectors have valved wind traps which have high aerodynamic drag in one profile and low aerodynamic drag in the opposite profile.
Claims11
An apparatus for deriving rotational kinetic energy from wind ambient to said apparatus comprising:
- a support adapted to be vertically disposed;
- first wind force extraction means pivotably connected to said support to rotate in a first direction substantially perpendicular to said support when exposed to wind, said first extraction means including at least one wind trapping means having a cup-shaped body with an open end and valving means disposed at the other end of said body for permitting the passage of wind in one direction but not in the other;
- and at least one means for interconnecting said at least one wind trapping means and said support;
- second wind force extraction means pivotably connected to said support to rotate in a second direction opposed to said first direction in a plane substantially perpendicular to said support when exposed to wind, said second extraction means including at least one wind trapping means having a cup-shaped body with an open end and valving means disposed at the other end of said body for permitting the passage of wind of one direction but not in the other, and at least one means for interconnecting said at least one wind trapping means and said support, said first and second extraction means both being disposed in an area directly responsive to said ambient wind without direction alteration of said wind except by said first and second extraction means;
- and
- means for generating electrical energy having a shaft and a housing, said shaft being coupled to said first extracting means;
- and
- wherein said first and second valve means includes means defining a plurality of open segments radially disposed about the central portion of said other end, a plurality of flexible flap means larger than said open segments and covering each of said open segments on the interior of said body, and means for fixedly securing each of said flap means to said central portion and for permitting each of said flap means to convergingly flex toward the interior of said body.

- and
- wherein said first and second valve means each includes means defining a plurality of open segments radially disposed about the central portion of said other end, a plurality of flexible flap means larger than said open segments and covering each of said open segments on the interior of said body, and means for fixedly securing each of said flap means to said central portion and for permitting each of said flap means to convergingly flex toward the interior of said body.
