PATENT INFORMATION

The company and affiliates hold several patents relating to manufacturing and sale vertical axis wind turbines.

Vertical Axis Wind Turbine

(Pat. No. 9,598,758; Issued March 21, 2017)

A vertical axis wind turbine (VAWT) may be configured to include air or water bearing supports. The VAWT may be configured to float. The VAWT may include a 360.degree. 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.

Patented Method of Manufacturing Large Steel Rings

(Pat. No. 8,943,688; Issued February 3, 2015)

Manufacturing method comprising primarily:

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.

Gearless vertical axis wind turbine with bearing support and power generation at perimeter.
