Patent ID: 7675189

Claim:
A fluid-powered electric generating system comprising: a frame configured to couple to a tether system; at least one power generation module mounted to the frame and configured to provide lift from a flowing fluid to maintain the electric generating system within the flowing fluid, the at least one power generation module comprising: an outer holding structure attached to the frame; an inner rotating structure, including a rotor shaft, disposed within and configured to rotate relative to the outer holding structure; a rotor having a plurality of blades attached to the rotor shaft and configured to be rotated by the flowing fluid to create a torque on the rotor shall which rotates the rotor shaft and the inner rotating structure relative to the holding structure; and a plurality of generators attached to the holding structure, each generator having a drive shaft engaged with the inner rotating structure so that the torque from the rotor is transmitted to the generator for production of an electrical power.
