Chaque lame (1) est montée sur un arbre (2) dans une structure de soutien avec une roue dentée solidaire incorporée (3). Chacune des quatre roues dentées (3) est reliée par une roue dentée libre (4) à une roue dentée centrale (5) située sur un arbre central (6). L'arbre (6) est à son tour attaché à une roue dentée (7) qui entraîne des éléments (8) d'alimentation en puissance par des roues dentées supplémentaires (9). Le bilan d'énergie éolienne appliqué aux différentes lames (1) est tel qu'il fait l'ensemble de lames tourner dans le sens horaire. L'engrènement des différentes roues dentées (3, 4 et 5) fait les lames (1) tourner autour des arbres (2) dans le sens anti-horaire; de même, l'arbre central (6) tourne aussi dans le sens anti-horaire, bien que l'agencement d'arbres (2) et de lames (3) tourne dans le sens horaire. En même temps, la ligne d'extension en coupe transversale de chaque lame (1) traverse toujours un seul point fixe imaginaire de référence X situé sur un cercle à travers les quatre arbres (2).
