Patent number: 8823197Abstract: Heated air rises in a long, diagonal chimney up the side of a mountain. The airflow in the chimney turns wind turbines. Air entering the chimney's feeder tubes is heated in stages, where each stage has its own solar concentration and thermal insulation needs. Water, water vapor and air can be preheated as they are shipped to a chimney's lower end. Both low heat for preheating and high heat can be stored for night electricity generation and for continuing the chimney's electric production during cloudy periods. Water vapor rising a considerable elevation in a diagonal chimney will condense, giving up latent heat to the chimney air as it produces distilled water or mountaintop snow. Artificial thunderstorm cells downwind from the chimney are discouraged through a reduction in negative ions in the outgoing air and through thorough mixing of chimney air with the atmosphere at the chimney's top.Type: GrantFiled: June 10, 2010Date of Patent: September 2, 2014Inventor: Paul Klinkman

Patent number: 8763386Abstract: This invention captures hydrokinetic energy to do work such as produce electricity. The hydrokinetic flow exerts a torque on a turbine wheel. The wheel causes a set of tanks to rotate around a horizontal centerline. Working fluid drains from tanks near the top of the wheel to drive a conventional turbine before draining into lower tanks. Although a mechanical power transmission driven by the turbine wheel is simpler in concept, scale up to large slowly rotating wheels encounters increasingly difficult design problems: transmission of 1 kW at 1 rpm requires 6,959 ft-lb. In contrast, the conventional turbine of the fluid drive system provides mechanical power for use at a much higher speed than the turbine wheel. Therefore, very large engines can be built without a step-up transmission or components that must withstand extremely large torque loads. One unit can produce reliable 24/7 utility-scale base-load electrical power.Type: GrantFiled: August 6, 2010Date of Patent: July 1, 2014Inventor: Geoffrey Byron Greene

Patent number: 8766466Abstract: An underwater apparatus for generating electric power from ocean currents and deep water tides. A submersible platform including two or more power pods, each having a rotor with fixed-pitch blades, with drivetrains housed in pressure vessels that are connected by a transverse structure providing buoyancy, which can be a wing depressor, hydrofoil, truss, or faired tube. The platform is connected to anchors on the seafloor by forward mooring lines and a vertical mooring line that restricts the depth of the device in the water column. The platform operates using passive, rather than active, depth control. The wing depressor, along with rotor drag loads, ensures the platform seeks the desired operational current velocity. The rotors are directly coupled to a hydraulic pump that drives at least one constant-speed hydraulic-motor generator set and enables hydraulic braking. A fluidic bearing decouples non-torque rotor loads to the main shaft driving the hydraulic pumps.Type: GrantFiled: April 23, 2012Date of Patent: July 1, 2014Assignee: Aquantis, Inc.Inventors: James G. P. Dehlsen, James B. Dehlsen, Alexander Fleming

Publication number: 20140175798Abstract: A power generation system comprising a first vessel, a second vessel, a pump operably connected to the first vessel and the second vessel, and a turbine manifold assembly operably connected to the first vessel and the second vessel, wherein the pump creates a positive pressure in the first vessel to force a fluid in a first direction through the turbine manifold assembly and into the second vessel to a pre-determined level by a negative pressure in the second vessel, wherein, once the fluid reaches the pre-determined level in the second vessel, the pump creates a positive pressure in the second vessel to force the fluid in an opposing second direction through the turbine manifold assembly and back into the first vessel by a negative pressure in the first vessel to complete a cycle is provided. Furthermore, associated methods and a turbine manifold assembly is also provided.Type: ApplicationFiled: December 20, 2012Publication date: June 26, 2014Inventor: Howard G. Hoose, JR.
