Abstract
A fluid turbine 65 is provided, including a rotor 16, including a vertical rotation axis 12, on which at least two rotor blades 18, 20, 22 are arranged, wherein the rotor 16 is arranged within a housing 70, wherein a top 72 and a bottom 74 of the housing 70 are arranged essentially vertical to the rotation axis 12. Each rotor blade 18, 20, 22 has at least a first height 68 at a second distance 69 parallel to the rotation axis 12 and the second height 66 at a second distance 67 parallel to the rotation axis 12, wherein the first distance 69 and the first height 68 are smaller than the second distance 67 and the second height 66, wherein the rotor 16 is rotatable relative to the housing 70. Due to the design of the housing 70, the fluid turbine 65 has particularly high efficiency.
