Abstract
A power generator comprising: a lifting body for suspension in a moving fluid; a control station; and at least two tethers for tethering the lifting body to the control station. The control station is arranged to transform oscillating tension in the tethers produced by an oscillating movement of the lifting body into mechanical motion.
Claims19
A power generator comprising:
- a lifting body for suspension in a moving fluid;
- a control station;
- and
- at least two tethers for tethering the lifting body to the control station,
- wherein the control station is arranged to transform oscillating tension in the tethers produced by an oscillating movement of the lifting body into mechanical motion.
A power generator as claimed in any preceding claim wherein the control station comprises tied points for attaching the tethers and is arranged to oscillate the tied points of the tethers.
A power generator comprising:
- a lifting body for suspension in a moving fluid;
- a control station;
- and
- at least two tethers for tethering the lifting body to the control station, wherein the control station is arranged to provide rocking motion for control of the pull Generated on the tethers by the lifting body and to provide a translational motion for extracting power from the change of pull in the tethers.
A control station for a power generator using a lifting body in a fluid stream comprising:
- at least two tied points for the connection of at least two tethers for tethering the lifting body to the control station;
- and
- means for transforming oscillating tension in the tethers produced by an oscillating movement of the lifting body into mechanical motion.
A control station for a power generator using a lifting body in a fluid stream comprising:
- at least two tied points for the connection of at least two tethers for tethering the lifting body to the control station;
- and
- means for providing a rocking motion to control the pull generated on the tied points and for providing a translational motion to extract power from the change of pull on the tied points.
A method of extracting power from a fluid flow comprising the steps of:
- suspending a lifting body in the fluid flow using at least two tethers;
- and
- transforming an oscillating tension in the tethers produced by an oscillating movement of the lifting body into mechanical motion.
A method of extracting power from a fluid flow comprising the steps of:
- suspending a lifting body in the fluid flow using at least two tethers;
- providing a rocking motion to control the pull generated on the tethers by the lifting body;
- and
- providing a translational motion for extracting power from the change in pull in the tethers.
