Patent application numberDescriptionPublished
20090033098Controlling power extraction for wind power generation - A power generation system is disclosed. The power generation system comprises a kite connected to a line. The line is alternatively let out during a traction phase and recovered during a recovery phase. A power extractor connected to the line to extract power during the traction phase. And, a power extraction controller configured to target a preferred traction phase line velocity and a preferred recovery phase line velocity.02-05-2009
20090072092Bimodal kite system - A kite is disclosed. The kite comprises a first control element coupled to the kite in a first tether-force configuration, wherein the first control element is used to maintain controlled flight of the kite in the first tether-force configuration during a power generating phase. The kite further comprises a second control element coupled to the kite in a second tether-force configuration, wherein the second control element is used to maintain controlled flight of the kite in the second tether-force configuration during a recovery phase, and wherein during the recovery phase a tether force associated with the second tether-force configuration is reduced as compared to the tether force associated with the first tether-force configuration during the power generating phase03-19-2009
20090289148Faired tether for wind power generation systems - A tether for a kite wind power system is disclosed. The tether has a cross-section that is designed to have less aerodynamic drag than a tether with a circular-shaped cross-section.11-26-2009
20100295303Tethered system for power generation - A system for power generation comprises a wing, a turbine, a tether, and a tether tension sensor. The wing is for generating lift. The turbine is coupled to the wing and is used for generating power from rotation of a propeller or for generating thrust using the propeller. One end of the tether is coupled to the wing. The tether tension sensor is for determining a tension of the tether.11-25-2010
