This invention is made of a rotational hollow blade ( 11 ) turbine, which can be installed in watercourses for power generation. This system may include up to six propellers placed in hexagon shape, since this is the recommended shape for a better collection of the river flow, so that their movement does not obstruct the turbine rotation, and increases speed when immersing and emerging. The mentioned propellers are assembled on top of an axis of rotation, and the latter has an emission pinion ( 12 ) on both ends, which connects to a receiver pinion ( 13 ) placed inside a reduction gear box. Several turbines can be installed depending on the motive power of each hydric flow, and on the connection to two flow generators, one on each side, so that the power falling upon the turbine is regular and balanced.

Magnetic failsafe piston retention assembly, and related components, systems, and methods

A failsafe piston retention assembly, and related components, systems, and methods are disclosed. A failsafe piston retention assembly comprises a head comprising a head body having a first surface. The assembly also includes a piston having second surface, the piston slidably coupled with respect to the head. The piston has a retracted configuration and an unretracted configuration. In the retracted configuration, the second surface is fixed with respect to the first surface by a magnetic force. One advantage of this arrangement is that the piston is retained in its retracted configuration in the event of an operational failure of the piston mechanism. For example, for a hydraulically controlled piston, the magnetic force retains the piston in a retracted configuration even in the event of a loss of hydraulic pressure.

This instant utility application Ser. No. 15/213,996 claims the benefit of priority and, is submitted to replace provisional application 62/334/961 which is herein incorporated by reference in its entirety to improve U.S. Pat. No. 8,/710,414. The improvements are: 1. A method for creating electric power by utilizing Water to drive the generator.2. A method for creating electric power by utilizing Wind to drive the generator.3. A method for creating electric power by attaching solar panels to the collector. It is therefore an object of the present invention to provide improvements to U.S. Pat. No. 8,710,414 by creating kinetic energy from a cone; and, with attaching a framework with photovoltaic cells and directly aiming them at the sun, with a dual axis tracker control.The large opening of the cone is always the entrance and, the small opening is always the exiting end. By forcing a large amount of “fluid” (air/wind or water) to compress or, attempt to compress, a velocity pressure is created to power the various respected compressors. The “compressors” can be fan blades, blower wheels, centrifugal impellers, rotary blades, e.g., any type, including piston driven compressors with modified valves.In reference to the drawing, wind power, in addition to using others' directional controls, it might be best to utilize the counter weight, in the shape of a rudder, like on a boat, ship or, airplane filled with fluid. This would be the stabilizer and could be heated and, used to keep everything from freezing. The “fan blade” part of the drawing is to show it as a substitute for the blower wheel.In reference to the drawing, water power, in addition to using others' directional controls, it might be best to utilize the standard rudder or, to fasten it to a secure place.In reference to the drawing, water power, when used for tidal flows, the cone would be anchored to the sea bed, either on the bottom side or on the two sides and would change directions with the attaching of a ...

The assembly also includes a piston having second surface, the piston slidably coupled with respect to the head. The piston has a retracted configuration and an unretracted configuration. In the retracted configuration, the second surface is fixed with respect to the first surface by a magnetic force. One advantage of this arrangement is that the piston is retained in its retracted configuration in the event of an operational failure of the piston mechanism. For example, for a hydraulically controlled piston, the magnetic force retains the piston in a retracted configuration even in the event of a loss of hydraulic pressure. 1.

A system and method for converting pressure differentials to electricity is disclosed. Initially, a first chamber is empty and a second chamber holds compressed air/fluid. When the device is disposed in the large bodies of water, due to pressure difference inside the first chamber and the ambient pressure, water fills the first chamber. As the water passes through the first chamber, it turns the turbine or creates pressure difference in transducer to produce electricity. The device descends itself in the deeper water column due to added water in first chamber. When the device obtains equilibrium, the compressed air/fluid from second chamber is allowed to flow to the first chamber to evacuate the filled water. The evacuating water again turns the turbine or creates pressure difference in transducer to produce electricity. After evacuation of water, the device will ascend itself to a shallower depth and the process repeats. 1.

The power generator comprises: an upper structure having first and second structures including first and second balancing tanks and first and second machine rooms; a lower structure disposed on the lower portion of the upper structure and including a fluid flowing hole, a first round, and a fluid guide hole through which the fluid can flow; a turbine rotated by the movement of the fluid; an energy generation means for producing electricity by the turbine; and a fixing means. Thus, the power generator is floatable and movable on water so as to be moved to and installed in various locations. The first and second balancing tanks are filled with the fluid such that the power generator can be semi-submerged, and the height of the turbine is disposed at a position so that a shaft can be placed above the water surface such that the turbine is smoothly rotated, while preventing shaking by waving of the fluid and turning of the power generator, thereby improving energy production efficiency. Also, the fluid under the water surface is guided in a direction capable of operating the turbine while maximally preventing disruption to the flow of the fluid moving to the turbine through the first round of the lower structure, thereby improving energy production efficiency. 1.
