This invention relates to the harnessing of the wind, this can be done many
different ways,
but what is unique about my invention is that it has a vertical frame
structure that rotates and
has vertical luovers on one side of each arm of the windmill, they are free to
move 180 degrees
or less to minimize wind resistance when the luovers go against the wind, and
when they
rotate to the other side the wind blows them against the arm of the windmill
thus blocking the
wind on that side of the windmill creating a strong rotating force.
