Patent number: 7504741Abstract: The present invention provides a device for converting wind flow energy into mechanical energy, comprising a wind-engaging member having an aerodynamic profile which generates an uplift force in the direction of a load cable when the airflow direction is perpendicular to the load cable, a steering mechanism configured to produce a steered movement about a first axis or in a first direction of the wind-engaging member and about a second axis or in a second direction that is different from the first direction or axis of the wind-engaging member, relative to the airflow direction, and a control unit configured to use the steering mechanism to move the wind-engaging member along a predetermined flight path in a flight plane perpendicular to the load cable. The present invention further provides a method for converting wind flow energy into mechanical energy and a docking station for use with the device.Type: GrantFiled: March 30, 2007Date of Patent: March 17, 2009Assignee: Skysails GmbH & Co. KGInventors: Stephan Wrage, Stephan Brabeck

Patent number: 6485339Abstract: An electric propulsion pod for a ship having a electric propulsion pod heat rejection member. The electric propulsion pod is attached below the ship by a hollow ship access shaft. The electric propulsion pod contains an electric motor for producing a water propulsion. The electric motor generates an amount of heat that is conducted and subsequently released into the water through the electric propulsion pod and ship access shaft surfaces. The heat rejection member is fitted for increasing the conduction and subsequent release of the electric motor heat.Type: GrantFiled: April 10, 2001Date of Patent: November 26, 2002Assignees: Siemens Aktiengesellschaft, Schottel GmbH & Co.

Patent number: 6413128Abstract: The present invention pertains to a device for changing the direction of travel of a watercraft with a drive with a gondola-like underwater housing 2 having a contour favorable in terms of flow outside the hull 1 of the watercraft, past which water flows and which is connected to the hull 1 of the watercraft by a shaft 3, one end of which is associated with the underwater housing and the other end of which is associated with the hull 1 of the watercraft. A drive shaft 7, which carries at least one propeller 6 outside the underwater housing, is led out of at least one end of the gondola-like underwater housing 2. The change in the direction of travel of the watercraft 1 is brought about by the shaft 3 being mounted at its upper end pivotably on the watercraft 1 and by a pivoting motor 24 (toothed ring 20, motor pinion 21) acting on the shaft.Type: GrantFiled: December 12, 2000Date of Patent: July 2, 2002Assignee: Schottel GmbH & Co. KGInventor: Stephan Brabeck
