<p>The present invention relates to a two-door blade for a window power generator to generate a great deal of torque by accepting wind through a wide area on closed both doors in a low wind velocity; to automatically adjust torque by opening both doors to reduce an area for accepting wind in an intermediate wind velocity; and to minimize rotational torque by widely opening both doors in a high wind velocity. The two-door blade for a window power generator is opened or closed by tension, allows maximum power generation with the use of a simple device using a spring; and is capable of controlling a voltage to a certain extent by opening or closing the both doors.</p> |
