Abstract
A propulsion system for a seagoing vessel includes a rotatable frame and either (a) at least two masts coupled to the frame and each having a sail and a boom, or (b) at least two blades coupled to the frame. The rotatable frame and either the rotatable boom or at least two blades may be locked in position in a locked mode and unlocked and freely rotatable in an unlocked mode. A control system that is in communication in communication with a frame lock and either a boom lock or a blade lock and may be configured to determine when the vertical axis wind turbine should be in either the locked mode or the unlocked mode based on the direction of the wind and a direction that the seagoing vessel is traveling.
Claims11
A propulsion system for a seagoing vessel, the propulsion system comprising:
- a vertical axis wind turbine having a locked mode and an unlocked mode, the vertical axis wind turbine having:
- a frame having that is rotatable about a central axis when in the unlocked mode and non-rotatable about the central axis when in the locked mode,
- either (a) at least two masts coupled to the frame, each having a sail and a boom that is rotatable when in the unlocked mode and non-rotatable when in the locked mode, or (b) at least two blades coupled to the frame, the at least two blades when in the unlocked mode and non-rotatable in the locked mode, and
- a mechanical member having a first portion coupled to the boom of one of the at least two masts and a second portion coupled to the boom of the other of the at least two masts or having the first portion of the mechanical member coupled to one blade of the at least two blades and the second portion of the mechanical member coupled to the other blade of the at least two blades, the mechanical member being configured to regulate positions of the two sails or two blades when in the unlocked mode;
- and
- a control system configured to selectively change the vertical axis wind turbine between the locked mode and the unlocked mode.
