The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.Type: ApplicationFiled: August 12, 2019Publication date: February 20, 2020Inventors: Garth Alexander Sheldon-Coulson, Brian Lee Moffat, Daniel William Place

Publication number: 20200056579Abstract: A secondary electric power system and method of operation are disclosed. The system contains a grid having an array of turbines by which pressurized fluid is used to generate electricity to power a residential, commercial, agricultural or industrial structure. The secondary system may be a backup power source to the structure when a primary source is temporarily unavailable or may be a primary source in some circumstances. The method pumps fluid from a first pressure to a second pressure and exposes the fluid to a grid of turbine driven generators, the pressure is reduced across the grid to a third pressure that is less than the second. Additionally embodiments of the system are integrated into and incorporate components of other building utilities, e.g. water, sewer and fire control.Type: ApplicationFiled: August 20, 2019Publication date: February 20, 2020Inventor: Chris BURNS

Publication number: 20200056581Abstract: The invention discloses versions of a horizontal axis wind turbine and methodologies for the design of wind turbines, which are capable of extracting both kinetic and thermal energy from the wind. The wind turbines disclosed use a large diameter forward inlet fairing to accelerate the airflow to the more effective outer radii of the turbine rotor where the airflow is constrained by an airfoil-shaped flow control ring. This serves to prevent rotor tip losses, to inhibit wake expansion, and to accelerate the airflow through the turbine. A similarly large diameter aft pressure recovery fairing promotes rotation and contraction of the wake downstream of the turbine. Further methodologies for optimization and detail design are disclosed.Type: ApplicationFiled: February 7, 2018Publication date: February 20, 2020Inventor: LARRY LEE MANSBERGER
