Abstract
The invention relates to a water craft comprising a kite element, which is connected to the water craft by a traction cable. The water craft is characterized in that the kite element is equipped with adjusting devices and an energy generation unit, which delivers energy when the tractive force that is exerted on the traction cable is modified.
Claims22
A watercraft having a kite element for propulsion of the watercraft, which is connected to the watercraft by a hawser configured to experience tensile force, characterized in that the kite element is provided with adjusting devices for adjusting the kite, with a power generating device which uses a change in tensile force for generating power which is independent of the tensile force, which emits power when there is a change in the tensile force exerted on the hawser, and with a storage unit for storing power generated by the power generating device, and the adjusting devices are driven by the generated power.
A watercraft having a kite element for propulsion of the watercraft, which is connected to the watercraft by a hawser configured to experience tensile force, characterized in that the kite element is provided with adjusting devices and with a power generating device for generating power which is independent of the tensile force, which emits power when there is a change in the tensile force exerted on the hawser, the power generating device having a piston/cylinder unit with a spring-loaded piston, with the cylinder being connected to the hawser and with the piston being connected to the kite element, or with the cylinder being connected to the kite element and the piston being connected to the hawser, and with the cylinder being connected to a pressurized-fluid reservoir via a non-return valve.
A watercraft having a kite element for propulsion of the watercraft, which is connected to the watercraft by a hawser configured to experience tensile force, characterized in that the kite element is provided with adjusting devices and with a power generating device for generating power which is independent of the tensile force, which emits power when there is a change in the tensile force exerted on the hawser, the power generating device having a spring-loaded toothed rod which is arranged such that it can move in a component and drives a generator via a pinion which is mounted on the component, and the component being connected to the hawser and the toothed rod being connected to the kite element, or the component being connected to the kite element and the toothed rod being connected to the hawser.
