Abstract: The present invention relates to a cyclonic or anti-cyclonic conversion generator comprising a hollow and rigid structure (1) having at the upper end thereof diffusing deflectors (2) to produce a venturi effect and means for converting the kinetic energy of the outside wind into electrical energy, said hollow and rigid structure comprising: means for generating a primary flow (3) and means for generating a secondary flow (4) or vortex core, using convectors (5), (6); and means that facilitate the vertical movement of the primary flow and the secondary flow, using slopes that increase the peripheral flow (12) or a central protrusion or convex surface (11). The generator can be used for generating cyclones and anti-cyclones and can be used with any fluid, such as wind or water. The generator allows the speed of the fluid to be increased, concentrating said fluid on the periphery, which results in improved performance and effectiveness.
