  • Patent number: 11835025
    Abstract: A hydrodynamic power generation assembly and method of use therefor for generating electrical power from the combination of kinetic energy, hydrostatic energy, and turbulent energy of water. The power generation assembly comprises a water accelerator assembly comprising a support structure which is at least partially buoyant and a baffle panel member (or an array of baffle panel members) having an opening, inter-panel spacing, or flow passageway around the baffle panel(s). A hydropower converter is supported from, by, or on the support structure and is operatively coupled to a generator. The hydropower converter is positioned behind baffle assembly. Water flowing through or around the baffle assembly has an increased velocity relative the ambient current and therefore is capable of generating more power relative to the ambient water where power generation assembly is deployed.

  • Patent number: 11708673
    Abstract: A reservoir (102) near an ice cap (104), and a graded terrace network (116) on the surface of the ice cap (104). The graded terrace network (116) collects runoff water across a wide area, both within the limits of the reservoir's (102) ice cap natural catchment area (112), and beyond it in the ice cap non-catchment area (114). The graded terrace network (116) directs the collected water into the ice cap natural catchment area (112) and from there it drains into the reservoir's ice-free catchment area (106), and then into the reservoir (102). This increases the volume of water stored in the reservoir (102). This additional stored water is used to power a hydroelectric power station (300) and for other uses. A second reservoir (406), connected to the reservoir (102) by a water pump (402) and a second hydroelectric power station (410), adds additional water storage and power generating capacity.

  • Patent number: 10935005
    Abstract: Systems and methods are disclosed for using electrical energy to store potential energy during a first period of electrical demand and, thereafter, to convert the stored potential energy into electrical energy that can be supplied to an electrical grid during a second period of electrical demand. During the first period of electrical demand, electrical energy is used to move one or more weight(s) from a first relative position of low potential energy to a second relative position of high potential energy. During time periods of high electrical demand, the system is used to move one or more individual weight(s) from the relative position of high potential energy to the relative position of low potential energy. As each individual weight moves from the position of high potential energy, the motion of the weight is used to cause a generator to generate electrical energy.

  • Patent number: 10907611
    Abstract: Aspects described herein include a method of generating a control schedule for a wind turbine. The control schedule specifies a maximum power level that varies over time. The method comprises determining a value indicative of a current remaining fatigue lifetime of the wind turbine or of one or more components. The method further comprises applying an optimization function to perform an optimization to determine an optimized control schedule. The optimization comprises varying a plurality of parameters of an initial control schedule to produce a varied control schedule, estimating a future fatigue lifetime to be consumed by the wind turbine or the one or more components over the duration of the varied control schedule, and constraining the optimization according to one or more input constraints.

  • Patent number: 10873274
    Abstract: The invention provides an energy generation system comprising a generator having charged mutually rotating plate elements, and comprising an integrated drive mechanism for precisely controlling a separation distance between the plates. The drive mechanism provides a separation which varies as a function of the speed of rotation, hence assimilating separation control within the natural operation of the device. Embodiments provide plates comprising self-generating bearings, both hydrodynamic gas and fluid bearings and centrifugal regulator solid bearings, the bearings providing a supporting force between the plates of a magnitude which increases as the rotational speed of the plates increases. Methods of energy generation are also provided.

  • Patent number: 10858087
    Abstract: A vertical-input outboard-motor angled-drive lower unit apparatus and method for improved operations in shallow, muddy, marshy water or water choked with vegetation or obstacles. Vertically applied single-direction rotational power from an outboard motor engine is transferred to operator-controlled forward and reverse rotational power applied at an acute angle to the horizontal water surface. The apparatus is cooled by an external flow of water without being taken into any port which might become blocked. A thrust redirection plate reflects otherwise wasted propeller thrust, especially when operating in reverse, for more efficient operation and reduced churning of the water surface. An angled skeg and the angled orientation of the output shaft and housing deflect obstructions.

  • Patent number: 10823136
    Abstract: The APPARATUSES, METHODS AND SYSTEMS FOR HARNESSING THE ENERGY OF FLUID FLOW TO GENERATE ELECTRICITY OR PUMP FLUID include a device which, when placed in fluid-flow, harnesses the kinetic energy of the flow to generate electricity or to perform useful mechanical work such as pumping. For example, the undulating mechanical action of traveling waves along flexible fins may be harnessed by summing the varying speeds and torques along the fins into a unified circulatory system for power take-off or fluid extraction. The device may include two fins, a chassis, and bellows/pistons/rotary vanes and the like which are connected via a circulatory system of tubes or conduits.
