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.

A system includes at least one capacitor comprising a dielectric material having a Curie temperature, each capacitor exhibiting an increased capacitance at a temperature below the Curie temperature and exhibiting a decreased capacitance at a temperature above the Curie temperature, a liquid source positioned adjacent to the capacitor and having a temperature above the Curie temperature, and means for exposing the capacitor to the liquid source for a predetermined time so the temperature of the dielectric material exceeds the Curie temperature, at which point the capacitance decreases. A voltage storage is connected to the capacitors to capture the increased voltage discharged from the capacitors. The capacitors are then removed from the liquid source and cooled. The capacitors may iteratively be recharged, exposed to the liquid source until their temperature exceeds the Curie temperature, connected to the voltage storage, removed from the liquid source, and cooled.

A boomerang hydro multiplier machine designed to enhance hydro power by providing a greater area for collection and containment of fluid thereby providing more power including a wheel device and a guide channel with an endless carrier unit secured extending around the wheel device and through the guide channel, and a series of containers provided on the endless carrier unit used in transferring a continuous fluid supply through the guide channel in order to rotate the wheel device to generate rotational energy. A fluid flow is directed at the containers entering the guide channel from near the top of the wheel device and is discharged near or under the bottom of the wheel device after being directed through the guide channel. An increased electrical energy may be generated without increasing the associated water flow.

A portable hydro-generator for generating electrical energy may include a housing including a storage portion configured to store fluid; a first fluid tank attached to the housing and configured to store fluid; a fluid conduit arranged on the storage portion; a rotating element arranged within the housing; a pedal chain arranged through the storage portion and partially around the rotating element within the housing; and a power generator attached to the rotating element. In use, the fluid conduit may be engaged with a fluid pump to extract fluid from the storage portion to create a vacuum space within the storage portion. Upon creation of the vacuum space within the storage portion, the fluid within the first fluid tank may urge the pedal chain to rotate the rotating element to produce rotational energy. The power generator may convert the rotational energy to electrical energy.
