Title:
ATMOSPHERIC RESOURCES EXPLORER
Document Type and Number:
WIPO Patent Application WO2007139412
Kind Code:
B1
Abstract:
The invention herein described consists of a system destined to harness wind resources, transferring wind power to the ground station group on the surface, the process being performed through the tensioning and unwinding of the cable group connecting the airborne group to a reeler in the said ground station group. Through the control group the resultant force vector of the aerodynamic forces tensioning the cable can be significantly altered. This change in aerodynamic forces can be done in order to create two different phases which define the cyclic movement performed by the system: a work phase, where the resultant force vector is of greater magnitude and tensions the cable, unwinding it at the ground station group and thus producing power; and a recovery phase (which requires power from the system) when the cable is rewound in order to bring the airborne group back to its original position. Because the work produced in the work phase is of greater magnitude than the work required during the recovery phase, the system generates positive net power, which can then be introduced in the electrical grid, or stored as any other form of energy such as chemical or mechanical.
