What is disclosed is a vertical-axis wind turbine that looks somewhat similar to a vertical pole during no-wind or relatively low-wind conditions, i.e., when the turbine is waiting for relatively windy conditions, and that transitions between its “waiting state” and “wind harnessing state” automatically. Yet, to automatically transition between states, the turbine uses relatively few moving mechanical assemblies and uses no electric parts. The turbine has levers attached radially to a vertical mast and one or more wings attached to each lever. Each wing's mounting angle causes the wing to move the lever to which it is attached to deploy the wing(s) attached to that lever to rotate the mast. At an approximate rotation point of the mast, to avoid the deployed wing(s) from unduly opposing the mast's rotation, the wing's angle facilitates the retraction of the wing(s). The net drag of the wing(s) serves to rotate the mast.
