Vertical axis wind turbine arm-mast connection member

A connection member to connect a mast with an arm, the connection member comprising:

• an L-shaped bracket having a first portion and a second portion disposed perpendicular to the first portion, wherein the first portion is attached to a mast exterior surface;
• a first plate attached to the second portion, wherein a first plate plane is disposed perpendicular to a mast longitudinal axis;
• a second plate attached to an arm distal end, wherein a second plate plane is disposed parallel to an arm longitudinal axis;
• and
• a first pivot connector and a second pivot connector pivotally connecting the first plate and the second plate,
• wherein the arm distal end is disposed between the first pivot connector and the second pivot connector.

A vertical axis wind turbine comprising:

• a polygonal mast;
• an arm having an arm proximal end and an arm distal end;
• an L-shaped bracket having a first portion and a second portion disposed perpendicular to the first portion, wherein the first portion is attached to a polygonal mast exterior surface;
• a first plate attached to the second portion, wherein a first plate plane is disposed perpendicular to a polygonal mast longitudinal axis;
• a second plate attached to the arm distal end, wherein a second plate plane is disposed parallel to an arm longitudinal axis;
• and
• a pivot connector pivotally connecting the first plate and the second plate.
