Abstract
A vertical axis wind turbine (VAWT) is disclosed having air or water bearing supports. The VAWT may be configured to float. The VAWT may include a 360° rotor, having a precision machined noncorrosive bearing surface at its perimeter, with a system of wind capturing devices configured to collect kinetic energy of wind. The rotor may be supported by at least three air or water bearing supports positioned substantially at a perimeter of the rotor. Electrical generation components may be located substantially at the perimeter of the rotor.
Claims7
A method of manufacturing large steel rotors used with fluidic and magnetic bearings used in wind turbines and flywheel energy storage devices, the method comprising:
- providing a temporary center bearing and a spindle, the bearing and spindle configured to support, position, and spin a fabricated rotor for machining;
- machining a surface around an outside perimeter of the fabricated rotor to produce a machined surface;
- flame spraying a noncorrosive material onto the machined surface;
- and
- re-machining the flame sprayed surface into an appropriate bearing surface for fluidic and magnetic bearings.
