Abstract: A rotor assembly for a horizontal-axis wind turbine with blades support attachments. Each end of the supporting elements is fixedly or rotatably attached to one blade. In a new and improved embodiment, the blades start from the support element, skipping the swept area inside these elements but at the same time increasing many times the total swept area with substantially reduced cost. The support elements might be additionally attached to already existing wind turbine rotors. The reinforcing elements support and protect the blades from bending, breaking or falling apart in strong and gusty winds. The rotor of a wind turbine occasionally will rotate with speeds higher then normal and if the blades are not reinforced and properly balanced the whole assembly may start wobbling and then break apart from the tower or the blades may be damaged or may bend or break.

Abstract: A hybrid water pressure energy accumulating, tower assembly used to directly propel water pumps to raise water from low elevation reservoir(s) to high elevation reservoir(s) where it is used as a potential energy. The tower is electrically connected and positioned next to or close to a wind turbine or a wind or solar power plant. The tower includes in-tower storage reservoirs configured for storing water. The in-tower storage reservoirs could be defined by lower and upper water storage containers attached to the inner or outer surface of the tower that might be connected to other neighboring reservoir(s). The lifted water is used to generate electricity utilizing a hydropower generator.

Abstract: A highly efficient, low weight-to-power ratio and adjustable high compression, gasoline or diesel internal combustion engine consisting of a multitude of cylindrical casings parallel to each other or aligned sequentially on one axle. Each casing having one radially extending vane affixed to a shaft rotatably mounted within the casing upon two end plates and one longitudinally extending wall affixed on the inside of the casing. The casing and/or the end plates equipped with plurality of ports and conduits which enable communication between interior chambers of the cylinders, allowing for intake of combustible air-fuel mixture and exhaust thereafter. Ignition means delivering a spark at the end of each working cycle. An extendable and adjustable connecting rod assembly converting the oscillating bi-directional rotary motion of the power output shaft into a continuous unidirectional motion of the main shaft. A self lubricating mechanism incorporated into the engine.

Abstract: A hybrid water pressure energy accumulating, wind turbine tower assembly used to directly propel water pumps to raise water from low elevation reservoir(s) to high elevation reservoir(s) where it is used as a potential energy. The wind tower assembly includes a wind turbine having propeller with a rotor, a generator driven by the rotor and a yaw assembly attached to a tower with a foundation. The tower includes in-tower storage reservoirs configured for storing water. The in-tower storage reservoirs could be defined by lower and upper water storage containers attached to the inner or outer surface of the tower that might be connected to other neighboring reservoir(s). The wind turbine may be of the vertical or horizontal-axis type and may be installed inside a residential or commercial building. The lifted water is used to generate electricity utilizing a hydropower generator.

Abstract: A rotatably alternating air or water cooled two-stroke internal combustion engine comprising a cylindrical casing, and a rotor comprising two radially extending vanes affixed to a shaft rotatably mounted within the casing upon two end plates. Two longitudinally extending walls affixed to the casing. Sealing strips provided between said walls, the shaft, the vanes, the casing and the end plates respectively. Working and supercharging interior chambers between the vanes and the walls. The casing and/or the end plates equipped with ports which communicate with the interior chambers, allowing for intake of combustible air-fuel mixture and exhaust thereafter. Ignition means delivering a spark at the end of each working cycle. An extendable and adjustable connecting rod assembly converting the oscillating bi-directional rotary motion of the output shaft into a continuous unidirectional motion of the main shaft. A self lubricating mechanism incorporated into the engine.
