A generator has interchangeable wind (10, Figure 1) and water 14 turbine assemblies, and drive means 15 selectively connected to a drive shaft 2 that transmits torque to a generator 3 or other energy conversion device which is pivotably mounted 13 on a sailboat for immersion of the turbine in wind or water flow as required. The mounting arrangement may include a yaw arm 5, vertical tube 23, and brackets 22 and 26 attached to the sailboat. The bracketry is releasably mounted to the vertical tube 23, and the yaw arm 5 can rotate and slide about the vertical tube to allow positioning of the turbine in either air or water flow. The energy conversion device may be an alternator, pump or friction mill, and the drive shaft 2 may be flexible or telescopic and pass though the centre of the vertical tube 23. The orientation of the yaw arm may allow furling of the wind turbine at high wind speeds. A lanyard may be included to allow deployment and recovery of the machine, and to set the operating depth of the impeller. |
