1. A turbine blade mounting system for supporting each of a plurality of turbine blades between a pair of vertically spaced and rotatably supported frameworks of a vertical axis wind turbine, said turbine blade mounting system including a pair of mounting units respectively pivotally coupled to opposing ends of a corresponding turbine blade, each of said pair of mounting units comprising:
a carriage displaceably mounted to a corresponding one of said pair of frameworks, said carriage being displaceable along a radially directed path with respect to a rotational axis of said pair of frameworks;
a pivot receptacle mounted to said carriage and into which an end portion of an axial shaft of said corresponding turbine blade is received; and
a restraint system coupled to said carriage, said restraint system including at least a pair of mechanical energy storage elements coupled between said carriage and said corresponding framework for applying a force to said carriage in opposition to displacement of said carriage being displaced in either of opposing radial directions from an initial position.
