A fluid energy converter, such as windmill or a wind turbine, includes a rotor having a front rotatable hub and a back rotatable hub. In some embodiments, a plurality of blades extend from the front hub to the back hub. A suitable blade includes a front section, a tip, and a back section. In one embodiment, the chord of the tip cross section is at an angle relative to the tangent of the rotor radius. The tip chord can be perpendicular to the direction of movement of the fluid. In some cases, the profile of a blade front section, from its root to the tip, forms a concave curve. In one case, the profile of the blade tip, from a junction root to the tip, forms a convex curve. A front section, an apex, and a back section of a blade form a generally parabolic shape.
