Claim:
1. A vertical axis helical turbine assembly comprising: a first wing, a second wing and a third wing placed circumferentially with respect to each other about a vertical axis of a center hub, each respective wing having a first end with a first midpoint and a second end with a second midpoint, each said respective wing having a respective first arm connected from said first end to said hub and a respective second arm connected from said second end to said hub; each said respective wing having said first midpoint of said first end spaced sixty degrees from said second midpoint of said second end in a circumferential direction defined by a midpoint of said vertical axis; each said first end of each said respective wing having a curved first portion and a substantially triangular second portion, said substantially triangular second portion having a first side extending in a planar direction from a first point on said curved first portion and a second side extending in a planar direction to a second point on said curved first portion, said first side and said second side converging to each other to a first end second portion point, each said second end of each said respective wing having a curved first portion and a substantially triangular second portion, said substantially triangular second portion of each said second end having a first side extending in a planar direction from a first point on said curved first portion of each said second end and a second side extending in a planar direction from a second point on said curved first portion of each said second end, said first side of said second end and said second side of said second end converging to each other to a second end second portion point; each said first sides of said respective first end and said respective second end being more proximal to said vertical axis than said respective second sides; each said respective first end being connected to each said respective second end by a substantially solid member having a first edge extending from said first end second portion point to said second end second portion point, a second edge extending from an intersection of said respective second edge and said respective curved first portion of said first end to an intersection of said respective second edge of said respective curved first portion of said second end, a third edge extending from said first end second portion point to said intersection of said respective second edge and said curved first portion, and a fourth edge extending from said second end second portion point to said intersection of said respective second edge of said respective curved first portion of said second end; said third edge and said fourth edge having a portion extending along said respective first side of said substantially triangular second portion.
