Abstract
A multistage wind turbine or network of wind turbines with improved and optimized wind-directing, wind-shaping, and wind-power conversion features indicates that the shapes of these features directly affect the ability of the multistage wind turbine to use the power of moving air, such as wind, to spin a rotor and create torque on a rotor shaft to generate electricity. The wind-power-conversion mechanical efficiency described significantly improves upon previous designs by conversion of wind energy into electrical power at a superior price-to-performance ratio compared with existing alternative energy technologies.
Claims30
One or more multistage wind turbines comprising;
- a first stage portion with a first static stator, a vertical axis dynamic rotor that has vertical axis turbine blades attached to one or more rotational drive shafts that rotate said one or more rotational drive shafts in either a clockwise or counterclockwise direction and at least a second stage portion with a second stator and an axial rotor that includes second rotor axial turbine blades attached to said single rotational drive shaft wherein said first stage portion utilizes airflow directed into said vertical axis wind turbine blades from wind sources to provide torque that overcomes an inertial static force of said one or more rotational drive shafts so that said vertical axis turbine blades cause rotation of said one or more rotational drive shafts and such that wind continues past said vertical axis turbine blades through a conical portion contained within said axial rotor and toward said second rotor axial turbine blades whereby said second rotor axial turbine blades provide additional torque that adds rotational force to said one or more rotational drive shafts, wherein said one or more rotational drive shafts provides energy to at least one energy conversion device.
A network of multistage wind turbines wherein said multistage wind turbines each comprise;
- a first stage portion with a first static stator, a vertical axis dynamic rotor that has vertical axis turbine blades attached to at least single rotational drive shaft that rotates said single drive shaft in either a clockwise or counterclockwise direction and at least a second stage portion with a second stator and an axial rotor that includes second rotor axial turbine blades attached to said single rotational drive shaft wherein said first stage portion utilizes airflow directed into said multistage vertical axis wind turbine blades from wind sources to provide torque that overcomes a rotational drive shaft inertial static force so that said vertical axis turbine blades move rapidly enough to force rotation of said single rotational drive shaft and such that said airflow continues past said vertical axis turbine blades through a conical portion contained within said first rotor and toward second stator axial turbine blades whereby said axial rotor provides additional torque that adds rotational force to said single rotational drive shaft wherein said single rotational drive shaft provides energy to one or more energy conversion devices.
A method for obtaining energy and power efficiency from wind comprising;
- utilizing one or more multistage wind turbines, said one or more wind turbines having a first stage portion with a first static stator, a vertical axis dynamic rotor that has vertical axis turbine blades attached to one or more rotational drive shafts that rotate said one or more rotational drive shafts in either a clockwise or counterclockwise direction and at least a second stage portion with a second stator and an axial rotor that includes second rotor axial turbine blades attached to said one or more rotational drive shafts wherein said first stage portion utilizes airflow directed into said vertical axis turbine blades from wind sources to provide torque that overcomes an inertial static force of one or more rotational drive shafts so that said vertical axis turbine blades cause rotation of said one or more rotational drive shafts and such that wind continues past said vertical axis turbine blades through a conical portion contained within said axial rotor and toward said second rotor axial turbine blades whereby said second rotor axial turbine blades provide additional torque that adds rotational force to said one or more rotational drive shafts, wherein said one or more rotational drive shafts provides energy to at least one energy conversion device.
