Abstract: A kinetic energy transforming module includes a main shaft perpendicularly and rotatably standing on supporting surface and at least one blade structure horizontally mounted on the main shaft for driving the main shaft via wind power. The blade structure includes a horizontal shaft, an upper fan blade and a lower fan blade. The horizontal shaft is fixed on the main shaft. The two fan blades are respectively hinged on the horizontal shaft. Combining these three pieces together becomes a plane, perfect arc or a half circle shape. Find suitable place on the horizontal shaft building some stoppers to control the upper fan blade rotation angle from 5 to 90 degrees, and the lower blade rotation angle from ?15 to ?90 degrees. Hence, the blade structure is able to keep blades rotating and accelerating to achieve higher wind power efficiency.
