car steering wheel consists of profiles alari ultralight deformable, on its axis to obtain rotary lift more than the force of gravity and residual energy used for various purpose.

摘要

A device is described for generating energy. The device includes at least two ultralight airfoils rotating along their own axis, which functionally reproduce the characteristics of a propeller. The ultralight airfoils which characterize such aerodynamic configuration use pulling members (such as cables or tie-rods) to keep their shape when operating. An important weight reduction of the structure is thus obtained, which allows different applications in the aeolian generation field.
