Abstract

A windmill which comprises a rotor and a frame for rotatably supporting the rotor for a rotation around an axis. The rotor defines opposite ends and comprises a number of blade sections which extend between the opposite ends and define a surface of rotation around the axis during the rotation of the rotor. The rotor further comprises a set of frame structures, and each frame structure of the set of frame structures interconnect the number of blade sections and form a node at each blade section.
