ABSTRACT:
An auger shaped, fluid medium engaging member is disclosed which includes a helically or auger shaped outer region disposed about a longitudinal axis which passes through a central region of the member. The auger shaped outer region establishes at least one auger or helically shaped fluid medium engaging surface, which intercepts the flow of a fluid medium such as air or water, for effecting rotational movement of the fluid medium engaging member about its longitudinal axis. The auger shaped, fluid medium engaging member may be coupled to an electrical generator, for generating electrical energy upon rotational movement.
