Abstract: A power generation system (20) including an airborne electricity generator (30), a tether assembly (40) configured to carry electricity from the generator to land, the tether assembly having a first end portion (42) coupled to the generator, and a winch assembly (50) configured to reel the tether assembly onto a drum (52), wherein the winch assembly is configured to apply a reel tension to the tether assembly reeled onto the drum that is lower than a tension in the first end portion of the tether assembly.
Abstract: An electric generating system including a frame configured to couple to a tether system and at least one power generation module mounted to the frame. The at least one power generation module includes a holding structure attached to the frame, a rotating structure, including a rotor shaft, configured to rotate relative to the holding structure, a rotor attached to the rotor shaft, and a plurality of motor/generators attached to the holding structure, each including a drive shaft configured to engage with the rotor shaft.
Abstract: An electric power-generating system configured to convert a source of energy to electricity by turning a rotor shaft with the source of energy includes a mounting plate coupled to the rotor shaft, a drive gear coupled to the rotor shaft and configured to move when the rotor shaft moves, and a plurality of motor/generator devices mounted to the mounting plate. Each motor/generator device includes an output shaft configured to rotatably couple with the drive gear. Each motor/generator device couples independently to the drive gear to provide a plurality of redundant power generating motor/generator devices.
