  • Patent number: 11313341
    Abstract: The portable river turbine system is a small-scale electricity generator whereby boaters, fishers, or other individual entities can use the current of a river or other body of water to power or charge small electronic devices such as phones, lights, or radios. The detachable propeller or wheel is attached at one end of the waterproof turbine housing. The turbine can be secured by the side bolting, by the vertical hook, or optionally by both. Said vertical hook has a telescopic expandable shaft, allowing for the shaft to be the optimal length to best submerge the turbine wheel or propeller and still attach to a boat, dock, or other surface above the water's level. Stationed on the top of the waterproof turbine housing are quick connections that can be used for wires and handles.

  • Patent number: 11248581
    Abstract: An encased wind turbine has a casing, rotationally symmetrical in relation to the longitudinal axis and has the cross-section of an airfoil. The radially inner upper side delimits a flow channel. A guide element is rotationally symmetrical in relation to the longitudinal axis projects by part of its length, contrary to the direction of flow, over the casing. The propeller drives a generator, arranged in the housing, for generating electrical energy. The propeller viewed in the direction of flow, is located at least approximately at the guide-element trailing edge. Impinged on by the main flow of the wind, while a bypass flow, owing to the airfoil profile, generates a negative pressure downstream from the guide element and thus accelerates the main flow, is generated between the casing and the guide element. The propeller may be located downstream from the guide element and arranged to be adjustable in its longitudinal position.
