Systems and methods related to linear turbine systems are presented. Each embodiment described herein may be designed as a single-stage, linear, impulse turbine system. In an embodiment, a linear turbine includes a first shaft extending along a first axis; a second shaft extending along a second axis, the second axis being separated from and substantially parallel to the first axis; a first plurality of buckets to travel a first continuous path around the first shaft and the second shaft along a first plane, the first path including a first substantially linear path segment between the first axis and the second axis; and a nozzle configured to direct a first fluid jet to contact the first plurality of buckets in the first linear path segment.

A water-driven turbine has an elongated endless conveyor with down and up streaming straightaways connected by travel-reversing turns. Paddles mounted on the conveyor present high resistance to waterflow on the downstream straightaway and low resistance to waterflow or the atmosphere on the upstream straightaway, the differential allowing the flow of water to continuously drive the conveyor which is connected to a power take-off shaft facilitating connection to a variety of energy-harnessing systems. The turbine can be towed, self-driven or mooring line manipulated to a flow site and is operable in unidirectional flows such as rivers and reversing flows such as tides at depths from surface to bottom. The paddles can be mounted or changed on shore, at the flow site and anywhere in between. The turbine is efficient in low and high velocity water flow, not easily damaged by floating debris, cavitation free and fish, mammal and environmentally friendly.

A turbine is provided having one or more vanes joined to respective balloons. Compressed or pumped gas entering the turbine is selectively directed toward desired balloons by selectively activating one or more input valves, in order to selectively inflate the balloons. Simultaneously, gas inside the balloons is selectively directed away from the balloons and out of the turbine by selectively activating one or more output valves, in order to selectively deflate the balloons. The turbine is configured for being at least partially submerged in a liquid. The selective inflation of the balloons generates buoyancy which pushes the balloons upward, thereby causing the turbine to rotate. The selective deflation of the balloons decreases buoyancy which may counter the turbine's rotation. The turbine's rotation can be converted to a desired form of energy via a suitable energy converter.

The present invention relates to a hydraulic device of reversible type adapted to be used both as a water turbine and a hydraulic pump. Said device has characteristics of simplicity of construction and use. In the case of use as a water turbine it does not require distributors of a particular shape and does not require drops of great heights being adapted to take advantage of the pressure of the fluid and not only of the speed thereof.
