1. One or more multistage wind turbines comprising;
a first stage portion with a first static stator and a vertical axis dynamic rotor that has vertical axis turbine blades mechanically connected to one or more rotational drive shafts that rotate said one or more rotational drive shafts in either a clockwise or counterclockwise direction and a second stage portion with a stationary conical portion and a second vertical axis dynamic rotor that includes second rotor axial turbine blades mechanically connected to said one or more rotational drive shafts, wherein said first stage portion utilizes airflow that continues 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 wherein wind continues past said vertical axis turbine blades through said conical portion, which is contained within said vertical axis dynamic rotor, and toward said second rotor axial turbine blades wherein said one or more rotational drive shafts provides energy to at least one energy conversion device.
