Definitions
- the top base of the existing wind turbine generator structure is usually a round plate, which when set on a plate on top of a tower, 40-60-80 feet, permits the easy rotation, plate to plate, of the structure such that the propellers are always perpendicular to the wind movement for maximum power from the wind. Any deviation to the oblique from the perpendicular to the wind reduces the speed of rotation of the propellers and is one method for slowing the rotational speed of the propellers in high winds.
- wind turbine generators on towers are isolated individually or together as a community labeled as a wind farm and these farms are common in California with 4,000 or more turbines providing electricity to cities and local communities.
- Wind farms are being expanded nationally in European countries, especially Denmark, Germany, Holland, Sweden and England. Canada has great potential and is slowly expanding the use of wind turbine generator to supplement hydro and nuclear power.
- the wind generator has a first rotor disposed with a first axis of rotation.... and a second rotor disposed with a second axis of rotation different from the first axis of rotation, each rotor providing power to the field rotor of a generator electrical energy is generated.
- Patent CA 2193972 The Multi-Unit Rotor Blade System Integrated
- the described wind turbine has a set of propeller type wind force collecting rotor turbines composed of an up-wind auxiliary rotor blade turbine being disposed on the front end of the combined bevel-planet gear assembly, and a down-wind main rotor blade turbine. These rotor blades rotate in opposite directions with respect to one another.
- a lightweight counter-rotatable propeller system driven by a rotatable shaft... system includes first and second counter-rotatable propellers, each propeller including a plurality of blades mounted on first and second hubs, respectively.
