A turbine includes a cone and a plurality of curvilinear blades extending substantially along the length of the cone, from at or near the apex of the cone to at or near the base of the cone. In one embodiment, each of the curvilinear blades includes two walls, a first wall oriented substantially upstream with respect to the direction of fluid flow and a second wall oriented substantially downstream with respect to the direction of fluid flow. The first and second walls come together to form the edges of the curvilinear blades. |
