1. A wind harnessing system comprising:
a substantially helical structure having at least a portion of a spiraling groove defined between adjacent revolutions of a substantially continuous inclined planar member that wraps around and projects from a central core, the inclined planar member being angled with respect to a ground plane, such that the adjacent revolutions of the spiraling groove are separated by the planar member;
at least one energy converter positioned at least partially within the portion of the spiraling groove, the energy converter comprising an electrical generator and a wind powered turbine, the generator being configured to generate electrical power from rotation of the turbine.
