20220186703 | SYSTEM AND METHOD FOR BALANCING OPERATIONAL SYSTEMS OF AN ELECTRIC GENERATOR - A system and method for harvesting electric energy from the earth's gravitational field includes a pneumatic, potential energy (PE) system which cumulatively generates a volume of compressed air with an energy equal to PE, during a predetermined duty cycle. This energy can then be released as an instantaneous burst of energy in the next consecutive duty cycle. Also included is an electro-magnetic system which continuously generates kinetic energy (KE) as a shuttle falls under the influence of gravity during each duty cycle. An interface between the two systems is provided by a water column that separates the two systems yet allows them to be interactive. Specifically, the burst of PE manipulates the water column to maintain its integrity as the shuttle uses the water column as a water pathway for a return to the shuttle's start point under the influence of its buoyancy. | 2022-06-16 |
20220186704 | POWER GENERATOR WITH MULTIPLE TURBINE UNITS - A power generator having an impeller configured to facilitate the translation of balls through a ball-actuated turbine and facilitate the transfer of water to drive a water-actuated turbine. The impeller is located within a fluid compartment and creates a turbulent water flow, which generates an inverted vortex. The impeller includes a central bore having an outlet communicating with the fluid compartment and an inlet communicating with a feed space. An array of balls is supplied to the impeller bore via the feed space and traverses the bore in response to the vortex. The balls ascend through the fluid compartment and an upper water tank. At a higher elevation, the ascending balls are routed downstream via gravity to the ball-actuated turbine, while water is routed downstream via gravity to the water-actuated turbine. After performing their respective turbine-driving actions, the water and balls recirculate to the feed space to repeat the cycle. | 2022-06-16 |
20220186705 | WIND TURBINE ROTOR BLADE CONFIGURED FOR REDUCED TRAILING EDGE NOISE - Wind turbine rotor blade with reduced trailing edge noise A wind turbine rotor blade is described, the rotor blade extending in a spanwise direction between a root end and a tip end, and extending in a chordwise direction between a leading edge and a trailing edge. The rotor blade comprises a series of serrations projecting from the trailing edge, each serration extending from a base to a tip to define a length of the serration. The rotor blade also comprises a respective distinct set of fins associated with, and arranged adjacent to, each of the serrations, each fin projecting from a surface of the blade and extending between a leading end and a trailing end to define a length of the fin. Each set of fins comprises multiple fins whose trailing ends are in spanwise alignment with, and are located at or upstream of, the base of the serration associated with the set. For each set of fins, each fin of the set has a greater length than the serration associated with the set, and the trailing end of at least one fin lies between spanwise edges of the serration associated with the set. | 2022-06-16 |
