Vertical axis wind turbine

A method of assembling and erecting a vertical axis wind turbine comprising the steps of;

• providing a ground embedded central support structure anchor and eight ground embedded guy cable anchors;
• assembling a hinge connection between a central support structure and said central support structure anchor with said central support structure in a substantially horizontal position;
• assembling an overlapping stacked assembly in a substantially horizontal position;
• said overlapping stacked assembly comprising said central support structure overlapping the lower end of a rotor shaft through a rotor lower bearing, an upper rotor bearing assembly overlapping the upper end of said rotor shaft;
• providing an erection gin pole and a hold down gin pole attached to said central support structure;
• attaching one upper bearing guy cable between said upper rotor bearing assembly and a footing attached erection winch, strung in tension over said erection gin pole, to define a temporary erection winch cable, to both hold together and erection pivot said overlapping stacked assembly;
• assembling and attaching at least two rotor blades to said rotor shaft;
• attaching an additional upper bearing guy cable between said upper rotor bearing assembly and said central support structure in tension and strung over said hold down gin pole to hold said overlapping stacked assembly together;
• pulling said temporary erection winch cable to pivot said overlapping stacked assembly about said hinge connection to a vertical position.
