A multi stage turbine for the generation of current comprising a first paddlewheel rotating in a first direction and mounted on a first axle that is connected to a gear system on a first side of the gear system, whereas the multi stage turbine comprises a second paddlewheel rotating in a second direction, counter directional to the first direction and connected to a second axle that is connected to the gear system on the first side of the gear system, whereby the first axle is concentric with and surrounding the second axle, characterized in that the multi stage turbine comprises a third paddlewheel arranged on a third axle and coupled to a second side, opposite the first side, of the gear system, whereby the third paddlewheel is arranged to rotate in the first direction or the second direction, whereby the third paddlewheel have a diameter that is larger than the first and the second paddlewheel and the multi stage turbine comprises a casing that is surrounding the paddlewheels and is forming a passage for the control of the fluid flow with a flow direction from the first paddlewheel against the second paddlewheel, whereby the casing is arranged at a predetermined distance from the first and second paddlewheel for overflow of a part of the fluid flow past the first and second paddlewheel to the third paddlewheel. |
