1. A turbine, comprising:
- a plurality of blades configured to travel a path around a first axis and a second axis parallel to the first axis, the path comprising;
a first segment from the second axis to the first axis, the first segment being a first stage of the turbine,a second segment around the first axis,a third segment from the first axis to the second axis, the third segment being a second stage of the turbine, anda fourth segment around the second axis;
wherein each of the plurality of blades have an orientation relative to a vector of blade travel resulting in a blade negative stagger angle in the first stage of the turbine, and a blade positive stagger angle in the second stage of the turbine.

Abstract
Disclosed herein are linear hydraulic turbines in which the linear machine converts the majority of available energy in the flowing water into useful torque directly in the runner, leaving the outflow with very little velocity.

8. A turbine, comprising:
-
a plurality of blades attached to a structure and , traveling a path comprising a first stage substantially linear portion, a first substantially arc-shaped portion, a second stage substantially linear portion, and a second substantially arc-shaped portion; a plurality of stationary guide vanes arranged in a space enclosed by the structure; and a shroud positioned adjacent to the first substantially arc-shaped portion and conforming to a curvature of the first substantially arc-shaped portion, the turbine being configured to receive a free jet working fluid, the free jet working fluid having a flow pattern through the turbine in a plane substantially perpendicular to the first stage and the second stage. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
