The motionless structure is a hollow body and it is formed by a support structure and cover, being said interior space adapted to store electronic components, which can be directly supplied by the energy, produced. On its outer surface, air particles and pollutants filters can be installed, taking advantage of the aerodynamic shape of the motionless structure, which promotes air flow adhesion along its surface, making possible to capture particles along their preferred path. ## Claims ### Claim 1 A combined omnidirectional flow turbine comprising: one or more rotors placed in a vertical position, each of the one or more rotors including blades; an energy transformation element connected to the one or more rotors to convert mechanical energy to electrical energy; a motionless structure comprising an aerodynamic element, the aerodynamic element having a shape of an inverted radial wing surrounding laterally the one or more rotors therein and including an outer sidewall surface and an inner sidewall surface, said inner sidewall surface being continuously curved and bulging inwardly extending in a direction toward the one or more rotors from bottom intake flow to top exhaust flow, said motionless structure being a hollow body comprising: a support structure and a cover, wherein said support structure comprises an interior space configured to store at least one electronic component, wherein the support structure is connected to a vertical mounting mast, and said cover mounted to the support structure; and an electronic supply adaptation circuit, connected to the energy transformation element, configured to actuate said at least one electronic component; wherein the aerodynamic element with the shape of the inverted radial wing promotes creation of a combined air flow comprising a lower air flow and an upper air flow, the lower air flow directed in an ascending direction towards an entire area of the one or more rotors due to an aspiration effect caused by the combined lower air flow, and the upper air flow passing through a top exhaust of the aerodynamic element, wherein the motionless structure comprises at least one filter installed on the outer sidewall surface of the motionless structure. ### Claim 2 (depends on 1) The turbine according to claim 1, wherein the at least one filter is selected from an electrostatic filter, a high efficiency particulate air filter or Activated Carbon Technology filter. ### Claim 3 (depends on 1) The turbine according to claim 1, wherein the motionless structure further comprises an aerodynamic deflector with a brim on an upper portion of the motionless structure. ### Claim 4 (depends on 1) The turbine according to claim 1, wherein the at least one filter is installed on a lower part of the motionless structure. ### Claim 5 (depends on 1) The turbine according to claim 1, the motionless structure comprises one or more aerodynamic elements. ### Claim 6 (depends on 1) The turbine according to claim 1, wherein the blades of the one or more rotors comprise composite materials, magnesium alloys or injected polymers. ### Claim 7 (depends on 1) The turbine according to claim 1, wherein the turbine employs secondary flows from HVAC systems. ### Claim 8 (depends on 1) The turbine according to claim 1, wherein the energy transformation element is disposed in a center area of the turbine or at a ground level area of the turbine. ### Claim 9 (depends on 1) The turbine according to claim 1, wherein the energy transformation element is an electric generator. ### Claim 10 (depends on 1) The turbine according to claim 1, wherein the outer sidewall surface is covered with photovoltaic cells. ### Claim 11 (depends on 1) The turbine according to claim 1, wherein the motionless structure comprises a metallic material, a composite material, a concrete or textile material. ### Claim 12 (depends on 1) The turbine according to claim 1, wherein the motionless structure outer sidewall surface is of a radiofrequency-wave-transparent material. ### Claim 13 (depends on 1) The turbine according to claim 1, comprising lighting systems mounted in a lower part of the motionless structure. ### Claim 14 (depends on 1) A luminaire comprising the turbine as described in claim 1.
