| 20090308061 | Cangrier-M1 machine or C-M1 the powerful miracle perpetual motion machine designed for hydroelectric power generation water recycling concept - When water is pumped manually to the overhead tank, the weight of the water is felt on the opposite end of the lever.

| 20150052883 | HYDRAULIC POWER UNIT - A hydraulic power unit comprising a rear face and a front face spaced from one another includes an air inlet configured to receive air into the unit, and an air outlet configured to expel the air received into the unit. The hydraulic power unit further includes controls configured to provide a user interface. The controls and the air inlet are located on the front face, and the air outlet is located on the rear face. A coupler for a hydraulic power unit, configured to couple a drive shaft of the unit to a pump shaft of a hydraulic pump, includes a first aperture configured to receive the drive shaft, a second aperture configured to receive the pump shaft, and a hub configured to be received in a fan. The hub is configured to fixedly couple to the fan so that the fan is driven by the drive shaft. | 02-26-2015 |
| 20150113968 | TRANSIENT LIQUID PRESSURE POWER GENERATION SYSTEMS AND ASSOCIATED DEVICES AND METHODS - A transient liquid pressure power generation system and associated devices and methods are disclosed. The system can include a liquid source and a transient pressure drive device fluidly coupled to the liquid source to receive liquid from the liquid source. The transient pressure drive device can include a drive component, and a valve to cause a high pressure transient wave in the liquid traveling toward the liquid source to operate the drive component. The system can also include a liquid velocity continuation component downstream of the transient pressure drive device and a bypass conduit fluidly coupled to the liquid source and the liquid velocity continuation component. Additionally, the system can include a heat source fluidly coupled to the transient pressure drive device and the liquid source to receive liquid from the transient pressure drive device and heat liquid returning to the liquid source. The liquid velocity continuation component can operate to maintain continuous liquid flow from the liquid source to the heat source from the transient pressure drive device or the bypass conduit to cause substantially immediate maximum liquid flow velocity from the transient pressure drive device upon opening the valve. | 04-30-2015 |
| 20150322978 | SUBSEA FORCE GENERATING DEVICE AND METHOD - A water submerged device for generating a force under water. The device includes an enclosure having a piston that drives a ram, the piston dividing the enclosure into closing and opening chambers, the opening chamber connected to the low pressure recipient, and containing a first fluid. The device further includes a low pressure recipient for containing a first fluid having a lower pressure than the first fluid, and in selective fluid communication with the opening chamber of the enclosure via a first valve. In addition, the device includes a control module connected to the enclosure and in selective communication with the opening chamber of the enclosure via a second valve. The first and second valves are controlled so that only one of the low pressure recipient or the control module is in fluid communication with the opening chamber of the enclosure at a time. | 11-12-2015 |
| 20160025115 | SELF CONTAINED AND WEIGHT ENHANCED HYDROELECTRIC GENERATOR RESERVOIR - A portable self contained hydroelectric generator requires a reservoir of liquid to operate. This invention pertains to a self contained reservoir which uses earth's gravitational force to pressurize the contained liquid. This is achieved by placing a downward force using a weighted platform situated above the liquid. This in turn will provide an increased liquid flow to be used for hydroelectric power generation when said liquid is passed through a turbine. The flowing liquid will be collected in a second reservoir for reuse. | 01-28-2016 |
| 20160084216 | METHOD FOR MANUFACTURING A ROTATING PART OF A HYDRAULIC MACHINE, ROTATING PART MANUFACTURED ACCORDING TO THIS METHOD, HYDRAULIC MACHINE AND ENERGY CONVERSION INSTALLATION - A method is disclosed for manufacturing a rotating part which belongs to a hydraulic machine of an installation for converting hydraulic energy into electrical or mechanical energy. This rotating part includes blades distributed about an axis of rotation of the rotating part and extending from a leading edge to a trailing edge. This method can include manufacturing, in steel, a first part of each blade, which defines the leading edge thereof, manufacturing a second part of the blade in a material other than steel and attaching this to the first part of the blade so as to form a trailing edge. | 03-24-2016 |
