Abstract:
1. A device for generating energy, the device comprising: at least two ultralight rotating airfoils; and pulling means connected to the airfoils for keeping an aerodynamic shape of the airfoils when using the airfoils, the airfoils being mutually connected and adapted to be rotated around their common axis through a force applied by wind, so as to emulate a propeller performance, wherein the device is adapted, during rotation, to modify each of the airfoils independently by controlling a shape of each of the airfoils depending on its angular position when rotating, so as to obtain a resultant of lift forces not aligned with a wind axis, the device being adapted to be used both as traction system, and as aeolian generating system at a height, and the device is adapted to generate energy by rotation and to include rigid ribs adapted to transmit its movement to a generator placed at a center of the device, the device further including weights adapted to counteract a rotation torque linked to energy production, the weights being rigidly spaced from a rotation center of the generator to create a resisting torque that counteracts the rotation torque.
